Difference Between Dermatome and Cutaneous Innervation

Difference Between Dermatome and Cutaneous Innervation

Cutaneous innervation refers to the area of the skin which is supplied by a specific cutaneous nerve. Dermatomes are similar; however, a dermatome only specifies the area served by a spinal nerve.

What is a cutaneous nerve?

A cutaneous nerve is a nerve that provides nerve supply to the skin.

What is the difference between Dermatomes and Myotomes?

What are Myotomes and Dermatomes? A group of muscles that is innervated by the motor fibers that stem from a specific nerve root is called a myotome. An area of the skin that is innervated by the sensory fibers that stem from a specific nerve root is called a dermatome.

What is a nerve Dermatome?

A dermatome is an area of skin that's supplied by a single spinal nerve. Your spinal nerves help to relay sensory, motor, and autonomic information between the rest of your body and your central nervous system (CNS).

What is a dermatome used for?

“Dermatome (instrument)”: A surgical instrument used to cut thin slices of skin for the purpose of grafting of wounds and skin defects.

What are the 3 nerves found in the skin?

What is a Dermatome in anatomy?

A dermatome is an area of skin in which sensory nerves derive from a single spinal nerve root (see the following image). Dermatomes of the head, face, and neck.

What is a Myotome?

A myotome is, therefore, a set of muscles innervated by a specific, single spinal nerve. The term is also used in embryology to describe that part of the somite which develops into the muscles. There are 31 spinal nerves.

How do I know my Dermatome level?

Dermatome Testing is done ideally with a pin and cotton wool. Ask the patient to close their eyes and give the therapist feedback regarding the various stimuli. Testing should be done on specific dermatomes and should be compared to bilaterally.

What is Myotome and Dermatome?

A myotome is the group of muscles that a single spinal nerve innervates. Similarly a dermatome is an area of skin that a single nerve innervates. In vertebrate embryonic development, a myotome is the part of a somite that develops into the muscles.

Why do we test Dermatomes?

Dermatomes are primarily used to determine whether the sensory loss on a limb corresponds to a single spinal segment, implying that the lesion affects that particular nerve root (i.e., radiculopathy), and to assign a neurologic “level” to a spinal cord lesion.

What does nerve mean?

(Entry 1 of 2) 1 : sinew, tendon strain every nerve. 2 : any of the filamentous bands of nervous tissue that connect parts of the nervous system with the other organs, conduct nerve impulses, and are made up of axons and dendrites together with protective and supportive structures.
