The cervical plexus is situated deep to the sternocleidomastoid muscle, internal jugular vein, and deep cervical fascia. [1] It is situated anterior to the middle scalene muscle, and levator scapulae muscle. [1]
The supraclavicular nerve is a cutaneous (sensory) nerve of the cervical plexus that arises from the third and fourth cervical (spinal) nerves. It emerges from beneath the posterior border of the sternocleidomastoid muscle, then split into multiple branches. Together, these innervate the skin over the shoulder.
Injury to Erb's point is commonly sustained at birth or from a fall onto the shoulder.The nerve roots normally involved are C5 and partly C6. Symptoms include paralysis of the biceps, brachialis, and coracobrachialis (through the musculocutaneous nerve); the brachioradialis (through the radial nerve); and the deltoid (through the axillary nerve).
The thyrohyoid muscle is innervated (along with the geniohyoid muscle [1] [3]: 457, 709 ) by a branch of the cervical plexus [4] [3]: 538 - the nerve to thyrohyoid muscle (thyrohyoid branch of ansa cervicalis) [4] - which is formed by fibres of the cervical spinal nerve 1 (C1) [1] [2] [3]: 538 (and - according to some sources - cervical spinal nerve 2 as well [4] [3]: 457 ) that join and ...
Ansa cervicalis. The superior root of the ansa cervicalis (formerly known as descendens hypoglossi [1]: 500 ) is by fibres of the cervical spinal nerve 1 [1]: 344 [3] (and, according to some sources, of cervical spinal nerve 2 as well [3]) that have joined and run with the hypoglossal nerve (CN XII) for some distance before [1]: 344 progressively [1]: 369 branching off the CN XII in the ...
The transverse cervical nerve (superficial cervical or cutaneous cervical) is a cutaneous (sensory) nerve of the cervical plexus that arises from the second and third cervical spinal nerves (C2-C3). It curves around the posterior border of the sternocleidomastoideus muscle , then pierces the fascia of the neck before dividing into two branches.
The lower subscapular nerve contains axons from the ventral rami of the C5 and C6 cervical spinal nerves. [2] [3] It is the third branch of the posterior cord of the brachial plexus. [4] [5] It gives branches to 2 muscles: subscapularis muscle. [2] It usually gives 4 branches to innervate the subscapularis, and can give up to 8 branches. [1 ...
The brachial plexus is a network of nerves (nerve plexus) formed by the anterior rami of the lower four cervical nerves and first thoracic nerve (C5, C6, C7, C8, and T1).This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the armpit, it supplies afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand.
