The C1 nerve, also known as the first cervical nerve, primarily controls movements and sensations in the neck region. It innervates the muscles responsible for head and neck movement, particularly the sternocleidomastoid and trapezius muscles, which play key roles in head rotation and shoulder elevation. Additionally, the C1 nerve contributes to autonomic functions and provides some sensory information from the scalp.

What is innervated by the C1 and C2 nerves?
The C1 and C2 spinal nerves primarily innervate the muscles and skin of the neck and the back of the head. C1, also known as the suboccipital nerve, primarily innervates the suboccipital muscles, while C2, the greater occipital nerve, provides sensory innervation to the scalp and posterior head. Additionally, these nerves contribute to the cervical plexus, supplying motor and sensory fibers to surrounding structures.
What structure passes through the suboccipital triangle?
The vertebral artery passes through the suboccipital triangle, along with the first cervical nerves (C1) and suboccipital muscles such as the rectus capitis posterior major and minor, and the obliquus capitis superior and inferior.
What does the plexus for C1 - T1 do?
The cervical (C1-C4) and brachial (C5-T1) plexuses innervate the muscles and skin of the neck, shoulder, arm, and hand. They are responsible for motor control and sensation in these areas. The C1-C4 plexus primarily innervates the muscles of the neck and head, while the brachial plexus primarily innervates the upper extremities.
What cranial nerve control the eyes or visual functioning?
The optic nerve, or cranial nerve II, is responsible for visual functioning and carries visual information from the eyes to the brain.
Where does the accessory nerve originate?
The accessory nerve, also known as cranial nerve XI, originates from two parts: the cranial portion and the spinal portion. The cranial part arises from the medulla oblongata, while the spinal part originates from the upper cervical spinal cord (C1-C5). These two components combine and exit the skull through the jugular foramen before innervating the sternocleidomastoid and trapezius muscles.
What is innervated by the C1 and C2 nerves?
The C1 and C2 spinal nerves primarily innervate the muscles and skin of the neck and the back of the head. C1, also known as the suboccipital nerve, primarily innervates the suboccipital muscles, while C2, the greater occipital nerve, provides sensory innervation to the scalp and posterior head. Additionally, these nerves contribute to the cervical plexus, supplying motor and sensory fibers to surrounding structures.
What 2 muscles are innervated by cranial nerve XII besides the 4 intrinsic lingual muscles and the 4 extrinsic lingual muscles?
Geniohyoid & Thyrohyoid as the Hypoglossal nerve is joined by fibers from C1 which supply them
What are the release dates for Nerve Control - 1935?
Nerve Control - 1935 was released on: USA: 18 April 1935
What structure passes through the suboccipital triangle?
The vertebral artery passes through the suboccipital triangle, along with the first cervical nerves (C1) and suboccipital muscles such as the rectus capitis posterior major and minor, and the obliquus capitis superior and inferior.
What makes up the cervical plexus?
the cervical plexus is a network of nerves formed in the neck.formation : ventral rami of C1- 4 nerves. except first cervical nerve, other nerves divide into ascending and descending branches. these nerves unite to form loops on the anterior surface of the scalenus medius and levator scapulae muscles. the plexus is covered by the prevertebral fascia. the plexus is superficially related to sternocleidomastoid and internal jugular vein.branches: they are classified into superficial, deep and communicating branches.superficial branchesthey are cutaneous branches. transverse cutaneous nerve of neck (C2,3)lesser occipital nerve(C2)greater auricular nerve(C2,3)supraclavicular nerves(C3,4)deep branchesanterior branches supply: phrenic nerve(C3,4,5)- diaphragmrectus capitis lateralis (C1)rectus capitis anterior(C1)longus capitis(C1-4)longus colli (C3-8)inferior limb of ansa cervicalis(C2-3)scalenus anterior (C4,5,6)posterior branches supplysternocleidomastoidc2 levator scapulae c3,4trapezius- c 3,4scalenus medius c3,4.communicating branches:superior cervical sympathetic ganglion communicates with C1-4 nerves by grey rami communicantes

What nerves control the quadriceps?
The femoral nerve.
What is the explanation for the nucleus in a nerve cell?
Chemical control center and data repository. It has nothing to do with the function of the nerve cell as part of a nerve.
What is the spinal accessory nerve?
spinal accessory nerve (a nerve that helps control speech, swallowing, and certain movements of the head and neck)
What are the clusters of nerve cells that control the nerve system in flatworm are called?
In flatworms, the clusters of nerve cells that control the nervous system are called ganglia. These ganglia are often referred to as a "nerve ring" and serve as a centralized processing center for sensory information and motor control. Flatworms also possess a simple nerve net that connects these ganglia, allowing for coordinated movement and responses to stimuli.
What does the plexus for C1 - T1 do?
The cervical (C1-C4) and brachial (C5-T1) plexuses innervate the muscles and skin of the neck, shoulder, arm, and hand. They are responsible for motor control and sensation in these areas. The C1-C4 plexus primarily innervates the muscles of the neck and head, while the brachial plexus primarily innervates the upper extremities.
