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.
the heart will shrink
lose of sensation at the level of spinal nerve
when you cut or injure a nerve it can completely shut down your nervous system and if you don't consult with your doctor within 5 hours you will die
Nerves are needed to control muscles and other functions. Cutting the sciatic nerve would cause weakness of the leg, or even little to no function in the knee and foot.
Piriformis, it lies superficial to the sciatic nerve.
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.
Lower subscapular nerve
smooth muscle
muscle, nerve, connective and epithelial
the muscle doesn't move
The muscle will atrophy.
When the electrical impulse from a nerve stops, the muscle relaxes and returns to its resting state. This is because the nerve impulse initiates the release of calcium ions in the muscle cells, leading to muscle contraction. When the nerve impulse stops, the calcium ions are reabsorbed, causing the muscle to relax.
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.
The same thing that happens when you cut the Jugular, its like the main nerve in a car!
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.
When the optic nerve is pinched or cut, it can result in vision loss or blindness in the affected eye. This damage can impact the transmission of visual signals from the eye to the brain, leading to a variety of vision problems depending on the severity of the injury. Treatment may involve surgery to repair the nerve or manage any underlying conditions causing the compression.
Facial nerve
radial nerve
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.
Femoral nerve
deep peroneal nerve supplies the tibialis anterior muscle
