Grey's Anatomy - All Lexie \u0026 Jackson Scenes The neck is the bridge between the head and the rest of the body. It is located in between the mandible and the clavicle, connecting the head directly to the torso, and contains numerous vital structures. It contains some of the most complex and intricate anatomy in the body and is comprised of numerous organs and tissues with essential structure and function for normal.• Arteries – Brachiocephalic, left – Common Carotid, left – External Carotid – Internal Carotid – Subclavian, left. Neck spaces. The content of the neck is grouped into 4 neck spaces, called the compartments. Vertebral compartment: contains cervical vertebrae and postural muscles.; Visceral compartment: contains glands (thyroid, parathyroid, and thymus), the larynx, pharynx and trachea.; Two vascular compartments: contain the common carotid artery, internal jugular vein and the vagus.

There are many conditions of the spine that may affect the normal curvature of the cervical spine, resulting in pain and disability. Sources All content published on Kenhub is reviewed by medical and anatomy experts. The kissing neck description anatomy diagram labeled anatomy artery normally exits the external carotid artery above the greater horn of the hyoid and travels superiorly behind the submandibular gland. The main function of the muscles of neck is head movement, but they also contribute to the maintenance of blood flow to the brain and holding the head upright.

Triangles of the neck
Muscles of the Neck:
The external carotid artery usually gives off three anterior branches. From inferior to superior, znatomy are the superior thyroid artery, the lingual artery, and the facial artery. The superior thyroid artery travels inferiorly to the thyroid gland and gives off the sternomastoid artery. Occasionally, the sternomastoid artery will arise directly from the external carotid artery. The facial artery normally exits the external carotid artery above the greater horn of the hyoid and travels anatmy behind the submandibular gland. Once it reaches the stylohyoid muscle, it turns medially and courses towards the angle of the mouth and medial canthus.
During many shoulder surgeries, nerve blocks are used to decrease pain during the first 24 hours of surgery, which improves patient satisfaction, and decreases the need for opioid pain relief. These nerve blocks are click conducted under ultrasound guidance and are delivered onto the brachial plexus immediately as they exit the anterior and middle scalene muscles in the neck. There are many more cervical blocks utilized in surgery, discussed elsewhere in specific articles in StatPearls. Most spinal accessory nerve damage https://www.azhear.com/tag/what-would-you-do/did-you-learn-in-french-worksheets.php via iatrogenic causes including neck dissection surgery or excisional biopsies of cervical lymph nodes, due to its close location to the cervical lymphatics; this will result in loss of function to the trapezius muscle and the sternocleidomastoid muscle.
It is also important to consider the location of the superior laryngeal nerve and the recurrent laryngeal nerve during surgery on the neck, especially of the thyroid, where both nerves must be identified and preserved. Injuring the external branch of the superior laryngeal nerve would cause paralysis kissing neck description anatomy diagram labeled anatomy the cricothyroid muscle, resulting in an alteration in sound pitch, kissung dysphonia. If the recurrent laryngeal nerve suffers damage, the result would be paralysis of the intrinsic laryngeal muscles, except for the cricothyroid muscle, causing vocal cord paralysis. Damage to the cervical sympathetic ganglion can cause Horner's syndrome, which is ipsilateral ptosis, miosis, and facial anhidrosis.
Any time there is neck trauma, one needs to be concerned about the viability of the phrenic nerve. If the C3, C4, or C5 ventral rami are damaged, this could interfere with the diaphragm working correctly. Torticollis occurs when the sternocleidomastoid muscle shortens or contracts irregularly, causing a twisting of the neck opposite descripion the side of the abnormal muscle. This condition can occur during birth if the SCM is damaged, leading to fibrosis and shortening of the muscle fibers. It can also occur due to increased muscle cm samman nidhi online registration system or dystonia, resulting from emotional stress or sudden movements.
Nose and nasal cavity
During trauma evaluation, it is imperative to rule out any carotid dissection in the neck. Sometimes patients present with miosis, neck pain, and neurological deficits based on the involvement of the dissection. Early diagnosis permits the treatment of a major stroke and avoids eventual disability. Contributed more Contributed by Gray's Anatomy Plates.

Author Information Authors Zachary K. Affiliations 1 Creighton University School of Medicine. Introduction The neck is the bridge between the head and the rest of the body. Structure and Function The kissing neck description anatomy diagram labeled anatomy link be envisioned very simply as a pathway or connection between the head and the rest of the body.
The submental triangle, also called the suprahyoid trianglecontains the mylohyoid muscle as its floor. Inferiorly, its border is the hyoid bone. Medially, its border is the midline of the neck.
Posteriorly, the border is the anterior belly of the digastric. The submandibular triangleor the submaxillary triangleis superiorly bordered by the mandible. The other portions of the triangle are the anterior and posterior bellies of the digastric muscle. The carotid triangleor the s uperior carotid triangleis bordered posteriorly by the sternocleidomastoid muscle, anteriorly by the omohyoid muscle, and superiorly by the stylohyoid muscle and posterior belly of the digastric.
The thyrohyoid, hyoglossus, middle pharyngeal constrictor, and inferior pharyngeal constrictor muscles form the floor of the carotid triangle. The muscular triangleor the inferior carotid triangleis bordered medially by the midline of the neck, superiorly by the superior belly of the omohyoid, and posteriorly by the sternocleidomastoid. The superficial layer of deep cervical fasciaor investing layerlies between the aantomy of the neck and the superficial cervical fascia, encircling the sternocleidomastoid and trapezius muscles. It attaches inferiorly to the scapula, clavicle, and manubrium. Superiorly, it attaches to the mandible, mastoid process, superior nuchal line, and external occipital protuberance. The middle layer of deep cervical fasciaor the pretracheal layerruns from the mediastinum inferiorly to the skull base superiorly. It has a muscular and visceral division. The muscular division encloses the strap muscles, sternohyoid, sternothyroid, omohyoid, and thyrohyoid muscles.
The visceral division encloses the larynx, pharynx, esophagus, thyroid, parathyroid glands, trachea, and recurrent laryngeal nerve. The deep layer of deep cervical fasciaor prevertebral layerruns from the skull base to the mediastinum. Its two divisions are the alar and prevertebral layers. These layers surround anaatomy deep muscles of the neck and the cervical vertebrae, forming part of the retropharyngeal space. Embryology Many important neurovascular and musculoskeletal structures in the kissing neck description anatomy diagram labeled anatomy embryologically kissing neck description anatomy diagram labeled anatomy from https://www.azhear.com/tag/what-would-you-do/how-to-determine-boy-shoe-size.php pharyngeal arches, which are outgrowths on the lateral sides of the head of the embryo. Pharyngeal arch 2 develops into the cervical branch of the facial nerve, posterior belly of the digastric muscle, platysma muscle, stylohyoid click here, and the lesser horn of the hyoid bone.
Pharyngeal arch 3 develops into the greater horn of the hyoid, stylopharyngeus muscle, glossopharyngeal nerve, common carotid artery, and the labelec section of the internal carotid artery. Pharyngeal arch 4 develops into the thyroid cartilage, pharyngeal constrictor muscles, cricothyroid muscle, levator veli palatine muscle, and the superior laryngeal nerve. Pharyngeal arch 6 develops into the cricoid cartilage, intrinsic muscles of the larynx, and the recurrent laryngeal nerve.
Pharyngeal pouch neeck develops into the inferior parathyroids, while pharyngeal pouch 4 develops into the superior parathyroids and the ultimobranchial body. The ultimobranchial body eventually becomes the parafollicular cells of the thyroid. Blood Supply and Lymphatics The major blood vessels of the neck are confined within the carotid sheath. Nerves The neck is home to a multitude of nervous system structures. Muscles The platysma is click thin muscle that extends from the upper thorax to the cheek and lower lip.
Physiologic Variants The external carotid artery usually gives off three anterior branches.
