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 the transverse cervical nerve sensory or motor?
The transverse cervical nerve carries solely sensory fibers. Its main function is to provide sensory innervation to the skin overlying the anterolateral aspect of the neck.
What type of branches do the transverse cervical nerve belongs to?
The transverse cervical nerve arises from C2 and C3 and branches off the cervical plexus posterior to the sternocleidomastoid where it penetrates the deep cervical fascia and divides under the platysma into ascending and descending branches, providing sensation to the anterior and lateral neck.
What muscles are innervated by the cervical plexus?
The muscular branches pass deeply from the plexus to supply the rhomboids, the serratus anterior, the sternocleidomastoid, the trapezius, levator scapulae, and the scalenus medius. There are also branches that supply the muscles of the suboccipital triangle.
What nerves are affected by C2 and C3?
The C2 nerve provides sensation to the upper area of your head; C3 gives sensation to the side of your face and back of your head. Cervical nerve 4 controls your upward shoulder motion and is one of the nerves that controls your diaphragm (muscle at the bottom of your rib cage that helps you breathe).
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 is the function of cervical nerves?
Cervical nerves provide control and sensation to different parts of the body based on the spinal level from where they branch out. More specifically: C1, C2, and C3 (the first three cervical nerves) control the head and neck, including movements forward, backward, and to the sides.
Which of the following areas is innervated by the transverse cervical nerve quizlet?
The skin over the thyroid cartilage is innervated by the transverse cervical nerve, a cutaneous sensory nerve from C2 and C3 roots of the cervical plexus. The skin over the clavicle is innervated by other cutaneous sensory nerves from the C3 and C4 roots of the cervical plexus–the supraclavicular nerves.
Which nerve of the cervical plexus is most important for maintaining life?
One important branch of the cervical plexus is the phrenic nerve, which is formed primarily from the C4 nerve and some contributing axons from C3 and C5.
What is the longest and largest nerve in the body?
The sciatic nerve is the longest, largest nerve in your body. Your sciatic nerve roots start in your lower back and run down the back of each leg.
What are Rami?
rami) (Latin for branch) is the anterior division of a spinal nerve. The ventral rami supply the antero-lateral parts of the trunk and the limbs. They are mainly larger than the dorsal rami. Ventral ramus. The formation of the spinal nerve from the dorsal and ventral roots.
What is a major nerve of the cervical plexus?
Its branches consist of a superficial and deep set. The superficial branches are the great auricular nerve, lesser occipital nerve, transverse cervical, suprasternal, and supraclavicular nerves. The deep branches are the phrenic, communicantes cervicales, communicating, and muscular.
What is the clinical significance of the cervical plexus?
The function of the cervical plexus is to provide skeletal muscle control of the neck and upper torso as well as providing cutaneous sensation to parts of the occiput, neck, and shoulder. The greater occipital nerve originates from the second cervical nerve independent of the cervical plexus.
Is C5 part of the cervical plexus?
The 5th cervical nerve (i.e. the anterior ramus of spinal nerve C5) may also be considered as part of the plexus due to its contribution in the formation of one of the motor branches of the cervical plexus, the phrenic nerve.
What are the symptoms of a pinched nerve at C3 C4?
Signs and symptoms of a pinched nerve include:
tingling.burning.numbness.pain.muscle weakness.stinging pain, such as pins and needles.the area may feel it has “fallen asleep”
What does C6/C7 affect?
The C6-C7 disc is 6th cervical disc near the lower part of the neck, near the top of the shoulders. The nerve root that would be affected by the C6-C7 disc herniation controls the arms, the shoulders, the heart, the lungs, and more.
What are the symptoms of a pinched nerve at C5-C6?
C5-C6 (C6 nerve root): Pain, tingling, and/or numbness may be felt in the thumb side of the hand. Weakness may also be experienced in the biceps (muscles in the front of the upper arms) and wrist extensor muscles in the forearms. The C5-C6 disc is one of the most common to herniate.
Which of the following areas is innervated by the transverse cervical nerve quizlet?
The skin over the thyroid cartilage is innervated by the transverse cervical nerve, a cutaneous sensory nerve from C2 and C3 roots of the cervical plexus. The skin over the clavicle is innervated by other cutaneous sensory nerves from the C3 and C4 roots of the cervical plexus–the supraclavicular nerves.
What does C2 nerve innervate?
It originates from the spinal column from above the cervical vertebra 2 (C2). it innervates the rectus capitis anterior and rectus capitis lateralis muscles, and provides sensory nerves to the trapezius.
What nerve Innervates platysma?
The platysma was most commonly innervated by the cervical branch of the facial nerve (38.2%) or the cervical branch and mandibular branch of the facial nerve (60.5%), followed by the cervical plexus (0.6%), the cervical motor nucleus (0.6%), and the glossopharyngeal nerve (0.1%).
What does the supraclavicular nerve innervate?
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.
