Body: This is the major part of the pancreas that lies between its neck and tail. This body region looks very similar to a prism. The stomach is just above the body of the pancreas, and is separated by the omental bursa, a pouch that lies between these two organs. Tail: This is the narrowest region of the pancreas, runs to the left side of the abdomen, and is adjacent to the spleen. This narrow end of the pancreas releases pancreatic polypeptide amino acidswhich helps keep a check on the secretory activity of the organ. Surface: The body has 3 surfaces; namely, the inferior, posterior, and the anterior. The anterior surface lies opposite the front of the abdomen. The right half of this surface touches the transverse colon. The lower region of the right half touches the coils of the small intestine. The inferior surface is coated with a peritoneum serous membrane. The right kissing neck description anatomy diagram labeled diagram of the surface is narrower, while the left side is broader.
Margins: Margins refer to the border or edge of the pancreas. The pancreas is bounded by 3 margins, which include the superior, inferior, and the anterior margin. The superior margin is flat at the right, and becomes narrower as it reaches the tail. On the other hand, the inferior margin acts as a line of separation between the posterior and inferior surface. The anterior margin helps differentiate between the anterior and inferior surface of the organ. Pancreatic Duct: The pancreatic duct is a small tube that runs from the head of the pancreas and enters the duodenum. It acts like a medium of connection between these two organs.
In the pancreas, it runs from the left to right, and has numerous branches, known as lobular ducts. In the neck area of this organ, the pancreatic duct is slightly wider and moves downwards to connect with the common bile duct. This action opens the airways again and reestablishes breathing after swallowing. The omohyoid is a narrow muscle that connects the scapula to the hyoid bone. The muscle is composed of two bellies connected by an intermediate tendon, similar to the digastric muscle. The nerve supply to the omohyoid is provided by the ansa cervicalis. Its blood supply stems from the superior thyroid branch of the external carotid artery, and inferior thyroid branch of the thyrocervical trunk.
As other infrahyoid muscles, the omohyoid functions to depress to tell a story books hyoid bone and larynx to reopen the laryngeal inlet after swallowing. In addition, since the intermediate tendon of the omohyoid is connected to the carotid sheathwhen the muscle contracts, it pulls on the sheath and decreases the pressure in the internal jugular vein. This action is convenient as it increases the venous return from the head to kissing neck description anatomy diagram labeled diagram superior vena cava. The sternothyroid is a strap-like muscle that runs in the muscular triangle of the neck.
It arises from the costal cartilage of the first rib and the posterior surface of the manubrium of the sternum. The muscle then courses superiorly to insert onto the oblique line of the thyroid cartilage. The nerve supply to the sternothyroid muscle is derived see more the ansa cervicalis C1-C3. Its blood supply stems from the branches of the lingual and superior thyroid arteries. Like other infrahyoid muscles, the function of the sternothyroid muscle is kissing neck description anatomy diagram labeled diagram depress the hyoid bone and larynx, and thereby open the laryngeal inlet and reestablish breathing after swallowing. In addition, the sternothyroid muscle can pull the thyroid cartilage away from the hyoid bone and further open the laryngeal inlet, which can aid forced inspiration.
The thyrohyoid is a quadrilateral muscle go here in the muscular triangle of the neck. It arises from the oblique line of the lamina of thyroid cartilage, and courses superiorly to insert onto the lower border of the greater horn and the adjacent body of hyoid bone. The thyrohyoid muscle is innervated by the anterior rami of the first cervical spinal nerve C1 via the hypoglossal nerve CN XII. Its blood supply is derived from the infrahyoid and superior laryngeal branches of the superior thyroid artery, and the lingual branch of the external carotid artery.
In conjunction with other infrahyoid muscles, the thyrohyoid functions to depress kissing neck description anatomy diagram labeled diagram hyoid bone following its elevation during the go here of swallowing and vocalization. However, the thyrohyoid has an additional function when the hyoid bone is fixed, in which it elevates the larynx. This action is important for persons that need to sing high notes, such as vocalists. The anterior vertebral muscles are a deep group of muscles located just anterior to the cervical vertebral column.
These include the rectus capitis anteriorrectus capitis lateralislongus capitis and longus colli. These muscles are surrounded by the prevertebral fascia of the neck, which is why they are commonly referred to as prevertebral muscles. The principal function of these muscles is flexion of the head to varying degrees. The rectus capitis is a short strap muscle that arises from the anterior surface of the lateral mass of atlas C1 vertebra and kissing neck description anatomy diagram labeled diagram on the basilar part of the occipital bone, anterior to the foramen magnum. The innervation of this muscle comes from the anterior rami of spinal nerves C1 and C2, while its blood supply is provided by branches of the vertebral and ascending pharyngeal arteries. The function of the rectus capitis anterior is to flex the head at the atlanto-occipital jointas well as to stabilize this joint.
The rectus capitis lateralis is a small muscle that arises from the superior surface of the transverse process of the atlas C1 and ascends superiorly to insert onto the inferior surface of the jugular process of occipital bone. The muscle is innervated by branches of the anterior rami of spinal nerves C1 and C2, and vascularized by the ascending pharyngeal, vertebral and occipital arteries. The function of the rectus capitis lateralis is to flex the head laterally at the atlanto-occipital joint, and to help stabilize this joint during movement. The longus capitis is a long, flat muscle that arises from the anterior tubercles of transverse processes of vertebrae C3-C6 as four thin muscle strips. These muscle strips travel superiorly and link to insert onto the inferior surface of the basilar part of the occipital bone.
The muscle is innervated by anterior rami of spinal nerves C1-C3, and vascularized by the ascending pharyngeal artery, ascending cervical branch of the inferior thyroid artery and the muscular branches of the vertebral artery. The longus capitis functions as a weak flexor of the head when acting bilaterally, while unilateral contraction of the muscle produces ipsilateral rotation of the head. The longus colli, also called the longus cervicis, is a long muscle that spans the entire length of the cervical spine and the upper vertebrae of the thoracic spine.
It is divided into three parts:. The muscle is innervated by the anterior rami of the spinal nerves C2-C6.
Its blood supply stems from branches of the vertebral, inferior thyroid and ascending pharyngeal arteries. The main function of the longus colli is to flex the neck. In addition, the inferior movies with dance 2022 of the muscle can produce a weak ipsilateral flexion and contralateral rotation of the neck. You anatkmy now finished the muscles of the anterior neck. Take a break to test what you've learned with our quiz. The lateral neck muscles, also called the lateral vertebral muscles, are a group of muscles that pass obliquely along the lateral sides of the neck.
These include the anterior, middle and posterior scalene muscleswhich extend between the transverse processes of the cervical vertebrae and the upper two ribs. Due to their attachments, these muscles mainly produce ipsilateral flexion of the neck. The anterior scalene muscle is the most anterior of the scalene muscles. It arises from the anterior tubercles of the transverse processes of vertebrae C3-C6, and inserts onto kissing neck description anatomy diagram labeled diagram scalene tubercle and the superior border of the first rib. The anterior scalene muscle is innervated by the anterior rami of the spinal nerves C4-C6, and znatomy by the ascending cervical branch of inferior thyroid artery.
The function of the anterior scalene muscle depends on its point of action and whether the muscle acts alone or together with its contralateral counterpart. The middle scalene is the largest of the scalene diargam, that arises from the transverse processes of axis C2 and atlas C1and the posterior tubercles of transverse processes of the vertebrae C3-C7. The muscle then passes posterolaterally to insert onto the superior border of the first rib. The middle scalene muscle receives kissing neck description anatomy diagram labeled diagram nerve supply from the anterior rami of cervical spinal nerves C3-C8. Its blood supply stems from the ascending cervical branch of the inferior thyroid artery. The main function of the middle scalene muscle is to produce an ipsilateral flexion of the neck, when acting from below. When the cervical part of the vertebral column is fixed and the muscle is acting from above, it stabilizes or raises the 1st rib during forced inspiration.
The posterior scalene is the smallest and most posterior of the scalene muscles that arises from the posterior tubercles of transverse processes of cervical vertebrae C4-C6. It then extends posterolaterally and inserts into the external surface of the second rib. The nerve supply to the posterior scalene muscle is derived from the anterior rami of spinal nerves C6-C8, while its blood supply comes from the ascending cervical branch of the inferior dlagram artery and the transverse cervical branch of the thyrocervical trunk.
Similar to the middle scalene, the main function of the posterior scalene diafram ipsilateral flexion of the neck when acting from below, and stabilization or elevation of the second rib when acting from above. Surely you must be a bit intimidated by the amount of information you need to learn about the muscles of the neck. Shorten your studying time and make your life easier with our high-yield muscle anatomy charts! The posterior aspect of the neck is covered by muscles that connect the skull to the spinal column and pectoral girdle. These muscles can be divided into three layers.
Anterior neck muscles
The trapezius digram a large, flat, triangular muscle that forms a diamond shape with its contralateral counterpart. The muscle extends over the diagraam aspect of the neck and the superior part of the thorax. Based on the orientation of its fibers, the trapezius is divided into three parts; descending, transverse and ascending part, each of them having distinct attachments. The trapezius muscle is innervated by the kissing neck description anatomy diagram labeled diagram nerve CN XI. Its blood supply stems from branches of the occipital, superficial cervical, transverse cervical and dorsal scapular arteries. The main function of the trapezius is to produce lateral flexion and contralateral rotation of the head when acting unilaterally, and extension of the head when acting bilaterally.
In addition, the trapezius muscle stabilizes and produces movements of the scapula. Depending on which part of the trapezius contracts, these movements may be elevation, depression, retraction and rotation of the scapula. The superficial muscles of the posterior neck are the splenius muscles; the splenius capitis and splenius cervicis. These muscles also belong to the superficial layer of the deep intrinsic back muscles. The splenius muscles are innervated by the posterior rami of middle and lower cervical spinal nerves. The blood supply to the splenius muscles is by the occipital and transverse cervical arteries. The function of the splenius muscles is to extend the head when contracted bilaterally, whereas unilateral contraction produces lateral flexion and rotation of the head to the same side. What are in lip scrub reviews transversospinalis muscles are a large group of muscles that kissing neck description anatomy diagram labeled diagram belong to the deep layer of the intrinsic muscles of the back.
This group of muscles comprise the semispinalismultifidusand rotatores muscles. All diiagram these muscles are subdivided further according to the region they span.
