What position on the muscle cell where the nerve fibers connect?

The point where a nerve fiber connects to a muscle cell is known as the neuromuscular junction. This connection allows the nerve signal, or action potential, to be transmitted from the nerve to the muscle cell, triggering muscle contraction.


What is the space between the nerve and muscle called?

The space between a nerve and muscle is called the neuromuscular junction. This is where the nerve endings release chemical messengers called neurotransmitters, which signal the muscle to contract.


What happens to a muscle when an electrical impulse from a nerve stops?

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.


What part of nerve cell is adjacent to neuromuscular junction?

The axon terminal of a nerve cell is adjacent to the neuromuscular junction. The axon terminal releases neurotransmitters that transmit signals across the synapse to the muscle fiber. This signal triggers muscle contraction.


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.

When a muscle receives a nerve signal it and pulls on a tendon?

The muscle responds and pulls on a bone by way of a tendon. It can not react until the nerve tells it to.

Which substance is stored in the muscle's endoplasmic reticulum and then released when a nerve signal stimulates a muscle fiber?

Calcium ions


What happens to muscles when they lose their nerve supply?

What usually triggers muscle fibers to contract or relax?

The contraction is triggered by the release of calcium within the muscle which is triggered by an electrical signal from a nerve.


What causes muscle spasm?

The short answer is "concentrated lactic acid." Concentrated lactic acid can get trapped in the spindle in the muscle fiber and can not get out. When this lactic acid gets trapped in the muscle spindle the feedback nerves that are protected in the muscle spindle can only send a weak signal to the cerebellum. A weak signal from the feedback nerve to the cerebellum tells the cerebellum to contract a muscle. The feedback nerve is trying to send a strong signal which would tell the cerebellum to relax but because the concentrated lactic acid is trapped in the spindle and interfering with the feedback nerve the correct signal can not get to the brain. As a result the muscle keeps contracting and it never relaxes. The muscles gets stuck in this "bad signal loop" which causes many other problems in the body.


Which muscle trait is the ability to respond to a stimulus such as a nerve or hormone?

Muscle excitability is the ability to respond to a stimulus, such as a nerve signal or hormone, by generating an electrical impulse that leads to muscle contraction. This trait allows muscles to react to signals from the nervous or endocrine systems to produce movement.

What causes muscle contraction in the leg?

Muscle contraction in the leg is caused by the interaction between nerve signals from the brain and the muscle fibers. When the brain sends a signal to the muscle, it triggers the release of calcium ions, which then bind to proteins in the muscle fibers, leading to the contraction of the muscle.
