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
The muscle affected during an inferior alveolar nerve block is the temporalis muscle.
The piriformis muscle crosses the sciatic nerve in the buttock region. Compression or irritation of the sciatic nerve by the piriformis muscle can lead to sciatica symptoms like pain, tingling, or numbness in the buttock and down the leg.
Neurotransmitters such as acetylcholine transmit impulses between nerve and muscle cells. These chemical messengers are released at the synapse where nerve and muscle cells meet, allowing for the transmission of signals that trigger muscle contraction.
The gastrocnemius is stimulated by a branch of the sciatic nerve called the tibial nerve. This causes contraction and produces plantar flexion of the foot. When a person stands on their "tippy toes" that is plantar flexion. This is a function of this nerve.
The teres major muscle is innervated by the lower subscapular nerve, which arises from the posterior cord of the brachial plexus (C5-C8).
The muscle will atrophy.
When a nerve does not signal a muscle, the muscle will not receive the message to contract and therefore will not move or function properly. This can lead to muscle weakness, paralysis, or loss of function in the affected area. It is important for nerve-muscle signaling to be intact for normal movement and function.
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.
If a nerve is cut, the electrical connection is disrupted, and signals cannot pass through. This can result in loss of sensation and muscle function beyond the site of the injury. The nerve may regenerate over time, but recovery depends on various factors.
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 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 musculocutaneous nerve pierces the coracobrachialis muscle and supplies it with innervation.
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.
