Question

Difference between peripheral nerve and myotome

Answer 1

Note the difference between a myotome and a dermatome: ... The dermatome refers to an area of sensory innervation to the skin from a particular cord segment or mixed spinal nerve; it is overlapped by other dermatomes and does not correspond to the same area of distribution of the myotome.

Answer 2

Note the difference between amyotome and a dermatome: The myotome refers to all those muscles innervated from a particular segment of the cord eg. However, these muscles are all supplied by different peripheral nerves, which arise from different parts of the brachial plexus.
