Yes they do. once an impulse of great enough it opens these little reticulums which contain calcium. the calcium floods out causing a reaction that makes the muscle contract. All to do with ATP and so on and so forth . when the nerve stops this impulse the reticulums draw the calcium back in and the muscle relaxes.
What else can I help you with?
What stimualtes muscles?
Muscles are stimulated by signals from nerve cells called motor neurons
How does the nerve for the thumb contribute to its sensation and movement?
The nerve for the thumb, called the median nerve, provides sensation and controls movement in the thumb. It carries signals from the brain to the muscles in the thumb, allowing us to feel and move it. Damage to this nerve can result in numbness, weakness, or loss of function in the thumb.
What is the function axon terminal?
the primary function is to send nerve signals to the various parts of the body
What is function of axon terminal?
the primary function is to send nerve signals to the various parts of the body
How can an injury to a peripheral nerve cause loss of both sensory and motor function?
An injury to a peripheral nerve causes loss of both sensory and motor functions since that specific part is supplied by the motor pathway such as spinothalalmic and corticospinal.
What is the function of the nerve cells?
The functions of the nerve cells is to carry messages around our body. To adapt to their job, they are very long and are branched at each end.Nerve cells receive, carry, and pass electrical impulses.Neurons (or nerve cells) are the smallest unit of the nervous system which send signals to the rest of the body to perform what ever function the brain wants it to; such as telling the heart to beat.
What is a function of a motor nerve cell?
Motor nerve cells are the nerves that are supplied from the the brain to the muscles and the glands to perform a function. They are used in contracting and relaxing the muscles to perform certain specified functions.
What is the function of vagus nerve?
sympathetic fuction and the motor function mainly on the production of voice. http://www.answers.com/topic/vagus-nerve
What is the function of the median nerve Iliohypogastric nerve?
The median nerve controls muscles in the forearm and hand, providing sensation to the palm and fingers. The iliohypogastric nerve supplies motor function to the lower abdominal muscles and sensory innervation to the skin over the lower abdomen and groin area.
What is the function of the ventral root of a spinal nerve?
The ventral root of a spinal nerve contains efferent motor neurons that carry signals away from the spinal cord to muscles and glands in the body. These motor neurons control voluntary movements and autonomic functions.
An inability to extend the leg would result from a loss of function of what nerve?
An inability to extend the leg would result from a loss of function of the common peroneal nerve, a branch of the sciatic nerve. This nerve provides motor function to the muscles that extend the leg and dorsiflex the foot. Injury or compression of the common peroneal nerve can lead to weakness or paralysis in these muscles, resulting in difficulty extending the leg.
What function do nerve tissue perform?
Transmission of electrical impuses to help muscles to move and organs to function, etc.
