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.
No, while muscles can respond to nerve impulses, they do not initiate them. Neurons are responsible for initiating nerve impulses.
No, nerve cells don't contain muscle fibers. However, muscles have nerves running through them.
NO that is a complete lie
yes
Muscles are stimulated by signals from nerve cells called motor neurons
the primary function is to send nerve signals to the various parts of the body
the primary function is to send nerve signals to the various parts of the body
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.
sympathetic fuction and the motor function mainly on the production of voice. http://www.answers.com/topic/vagus-nerve
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.
Transmission of electrical impuses to help muscles to move and organs to function, etc.
energy in your body sends signals from your brain to your muscles to function
muscles relax and expiration occurs
The AN transfers signals originating from vibrations of the ear drum ( tympanic membrane ) to the brain for interpretation.
dendrites receive electrical and chemical signals from axon terminals.
The frog's spinal cord relays motor signals from the brain to the muscles of the body, and sensory information from the body to the brain.
