It cannot contract nor have stimulation. This is also known as paralysis.
When a nerve is cut, it will stop sending signals to the brain. This will cause a loss of feeling in the area as well as stop the muscle from working. If the nerve is not fixed, it can cause a ball of scar tissue to form that may give you an electrical feeling when touched.

What muscle in the buttock crosses the sciatic nerve?
Piriformis, it lies superficial to the sciatic nerve.
What are the General structural and functional differences between a nerve and smooth muscle cell?
The general structural and functional differences between a nerve cell and a smooth muscle cell are as follows. A nerve cell, controls the nervous system and automatic functions a smooth muscle cell is located in the smooth muscle where the nerve cell is.
Which nerve supplies teres major muscle?
Lower subscapular nerve
What muscle must be supplied by a somatic motor nerve?
smooth muscle
What is the most common type of tissue in the body?
muscle, nerve, connective and epithelial
What happens when a nerve does not signal a muscle?
the muscle doesn't move
What happens to muscles when they lose their nerve supply?
The muscle will atrophy.
What happens to a muscle when an electrical impulse from a nerve stops?
yes
What two prominent muscles have been affected if your right accessory nerve was severed in an accident and there was muscle atrophy?
When a nerve is cut, the muscle that communicates with the brain along that nerve no longer functions. this results in atrophy, the muscle thinning. It may not be repairable since the nerves degenerate when they get cut. If the surgeon says a nerve graft is doable, then there can be good sucess with a repair.
What happens when the serpentine belt breaks?
The same thing that happens when you cut the Jugular, its like the main nerve in a car!
What muscle and nerve will you need to isolate to study the physiology of nerve fibers?
To study the physiology of nerve fibers, you would need to isolate a specific muscle and the nerve innervating that muscle. This allows for the investigation of the interaction between the nerve and muscle, observing the transmission of signals and studying the response of the muscle to nerve stimulation. Commonly studied muscles and nerves in this context include the gastrocnemius muscle and the sciatic nerve in animal models.
What happens when the optic nerve is pinched or cut?
You would go blind, because the optic nerve would then be unable to transmit signals from the eye to the brain.
How is the nerve supply to platysma muscle?
Facial nerve
Which nerve supplies the anconeus muscle?
radial nerve
What muscle is cut in carpal tunnel surgery?
Actually no muscle is cut during this surgery. Instead, the surgeon cuts the transverse carpal ligament so pressure on the median nerve (the cause of carpal tunnel syndrome) can be released thus reducing the symptoms.
What nerve controls quadriceps muscle group?
Femoral nerve
Nerve supply of the tibialis anterior muscle?
deep peroneal nerve supplies the tibialis anterior muscle
