What does the supraclavicular nerve innervate?

Supraclavicular nerves. The supraclavicular nerves are three cutaneous nerves that emerge as a common trunk from the cervical plexus before branching to innervate the skin over the upper chest and shoulders.

Correspondingly, where does the supraclavicular nerve originate?

The supraclavicular nerves (descending branches) arise from the third and fourth cervical nerves; they emerge beneath the posterior border of the sternocleidomastoideus (sternocleidomastoid muscle), and descend in the posterior triangle of the neck beneath the platysma and deep cervical fascia.

Subsequently, question is, what muscles does the subclavian nerve innervate? The suprascapular nerve comes off the upper trunk, from roots C5-C6, and innervates the supraspinatus and infraspinatus, which are contributors to the rotator cuff apparatus. Arising from anterior divisions of C5-C6, also from the upper trunk, the subclavian nerve innervates the subclavius muscle.

Herein, what does the transverse cervical nerve innervate?

Transverse cervical nerve. The transverse cervical nerve, also known as the superficial cervical nerve, cutaneous cervical nerve or anterior cutaneous cervical nerve of the neck, is a cutaneous branch of the cervical plexus that innervates the skin covering the anterior cervical region.

Is supraclavicular part of the neck?

The supraclavicular fossa is an anatomically complex region of the upper neck, the contents of which lend themselves to diverse differential diagnosis for pathology within the region.

What is a supraclavicular nerve block?

The supraclavicular block is a regional anesthetic technique used as an alternative or adjunct to general anesthesia or used for postoperative pain control for upper extremity surgeries (mid-humerus through the hand).

What is supraclavicular fossa?

The Supraclavicular fossa is an indentation (fossa) immediately above the clavicle. In terminologia anatomica, it is divided into fossa supraclavicularis major and fossa supraclavicularis minor.

Where does the long thoracic nerve run?

The long thoracic nerve (LTN) originates from the ventral rami of cervical nerve roots 5, 6, and 7. It traverses the middle scalene muscle in the neck, passes under the brachial plexus and over the first rib. It then travels along and innervates the serratus anterior muscle (SA).

What are supraclavicular lymph nodes?

The supraclavicular lymph nodes are a set of lymph nodes found just above the clavicle or collarbone, toward the hollow of the neck. Swelling and pain in the lymph nodes are signs of an infection and sometimes, a malignancy (a cancerous tumor).

Where does the Musculocutaneous nerve end?

The musculocutaneous nerve arises from the lateral cord of the brachial plexus, courses through the anterior part of the arm, and terminates at 2 cm above elbow as lateral cutaneous nerve of the forearm.

What does Subscapular nerve innervate?

Subscapularis muscle Teres major muscle

What does the greater occipital nerve innervate?

Semispinalis capitis Scalp

Where is the Suprascapular nerve located?

Anatomy. The suprascapular nerve comes off the upper trunk of the brachial plexus, receiving innervation from both the C5 and C6 roots. The nerve runs posteriorly under the trapezius, passing through the suprascapular notch of the scapula to enter the supraspinous fossa (Figure 31–1).

What nerves are affected by c1 and c2?

C1, C2, and C3 (the first three cervical nerves) help control the head and neck, including movements forward, backward, and to the sides. The C2 dermatome handles sensation for the upper part of the head, and the C3 dermatome covers the side of the face and back of the head.

What nerves are affected by c3 c4?

C3- Commonly affects the trigeminal nerve which can cause trigeminal neuralgia. This is a facial pain that can be along three distributions involving the forehead, cheek, and jaw areas of the face. C4- Affects mostly the diaphragm.

Is the cervical plexus sensory or motor?

The cervical plexus lies deep to the sternocleidomastoid muscle. Its branches convey motor fibers to many cervical muscles and to the diaphragm. Its sensory fibers convey exteroceptive information from parts of the scalp, neck, and chest as well as proprioceptive information from muscles, tendons, and joints.

What muscles are innervated by c3?

C1-C2: Rectus capitis anterior and lateralis. C1-C3: Longus capitis. C2-C3: Prevertebral muscles and sternocleidomastoid. C3-C4: Levator scapulae, trapezius and scalenus medius.

What does c1 nerve do?

The cervical spinal nerve 1 (C1) is a spinal nerve of the cervical segment. C1 carries predominantly motor fibres, but also a small meningeal branch that supplies sensation to parts of the dura around the foramen magnum (via dorsal rami).

Where do the cervical nerves go?

The nerves emerge from the spine over the top of each vertebra, except for the eighth, which comes out of the spine under the seventh cervical vertebra. They connect the central nervous system to the body's limbs and organs.

What muscles are innervated by the ANSA Cervicalis?

Branches from the ansa cervicalis innervate most of the infrahyoid muscles, including the sternothyroid muscle, sternohyoid muscle, and the omohyoid muscle. Note that the thyrohyoid muscle, which is also an infrahyoid muscle, is innervated by cervical spinal nerve 1 via the hypoglossal nerve.

What is in the carotid triangle?

The main contents of the carotid triangle are the common carotid artery (which bifurcates within the carotid triangle into the external and internal carotid arteries), the internal jugular vein, and the hypoglossal and vagus nerves.

What nerve controls shoulder?

Nerves of the Shoulder

Axillary Nerve - supplies the Deltoid muscle.
Long Thoracic Nerve - supplies Serratus Anterior muscle and can cause Winging of the Shoulder.
Suprascapular Nerve - supplies supraspinatus and infraspinatus muscles and can be entrapped or diseased.
