Where is C2 dermatome?
The C2 dermatome is an area of skin that receives sensations through the C2 nerve. This dermatome includes the top and back of the scalp, the skin over the front of the neck, and the ear lobes.
What does C2 nerve control?
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 nerve comes from C2?
The cervical spinal nerve 2 (C2) is a spinal nerve of the cervical segment. It is a part of the ansa cervicalis along with the C1 and C3 nerves sometimes forming part of Superior root of the ansa cervicalis….Cervical spinal nerve 2.

What Dermatomes are responsible for sensation along the back?
5 lumbar dermatomes (L1-L5) that supply sensation from these spinal nerves in the lower limb (leg, foot, hip, etc.) – “L” refers to the five lumbar vertebrae, the disks below them, and the corresponding area of the lower back.
Where is C1 and C2 located?
The C1 and C2 vertebrae are the highest of the spinal vertebrae and are located at the very top of the neck, connecting the head to the spine. The C1 vertebrae is named atlas and the C2 vertebrae is named axis.
What is the C2 in your neck?
The axis (C2) cervical vertebra is the second vertebra of the spine. It is unique in that it contains the odontoid process — odontoid means “tooth” and that is what this bone looks like — that forms a pivot point on which C1 atlas can rotate. Injuries to the odontoid are common in motor vehicle accidents and falls.
What happens when C2 is out of alignment?
If the C1 or C2 vertebra is out of place, they can be placing undue pressure on the brainstem, causing it to send improper signals to the brain. The brain may think the body is in motion when it is not actually moving, leading to the symptoms of vertigo.
What causes C2 misalignment?
A misalignment at C0-C1-C2 can also come from sitting at a desk with poor posture, birth trauma, or falling out of a tree when you are a child. However, the most common way we see large trauma produced is from a concussion from either sports or work related injuries, or a car accident.
What is C2 called?
C2 (cervical vertebra): C2 is the symbol for the second cervical vertebra, which is also called the axis. It is so-named because the uppermost cervical vertebra (called the atlas) rotates about the odontoid process of the second cervical vertebra.
Where is v3 on the dermatome map?
Finally V3 is the lower face, otherwise referred to as the “Mandibular Division of Trigeminal Nerve”. C2 (“Occipital Protuberance”) impacts the back of the head and C3 (“Supraclavicular Fossa”) is part of the neck. On that map, C4 is in the clavicle region and C5 is the upper arms.
Where are C5 and T1 in the dermatome?
As noted before, dermatomes overlap, but there are principal dermatomes. One of the online maps shows that C5 is for the clavicles, as well as lateral parts of the upper limbs (which also include C6 and C7). C8 and T1 are for the medial sides of upper limbs.
How are dermatome maps used in the medical field?
Dermatome Map. Dermatome maps show the sensory distribution of each dermatome across the body. Clinicians can use test touch with a dermatome map as a way to localise lesions, damage, injury to specific spinal nerves, and to determine the extent of the injury, for example, if a patient is experiencing numbness in only one area.
Where are dermatomes located in the human anatomy?
A dermatome is the area of the skin of the human anatomy that is mainly supplied by branches of a single spinal sensory nerve root. These spinal sensory nerves enter the nerve root at the spinal cord, and their branches reach to the periphery of the body.
