The eye muscles have a ratio of about axons) per muscle fiber(s

The IR of the eye muscles is approximately 1 muscle fiber to 1 axon which has a ratio of 1:1. The greater the IR, the bigger the strength is produced by the motor unit. A group of muscles that are innervated by one spinal segment is called a myotome.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
