the motor unit
A single alpha motor neuron together with all the all the muscle fibers it innervates is referred to as a 'motor unit'.
A motor neuron and all of the skeletal muscle cells it stimulates is called a motor unit.
The space between the ending of one neuron and the communication with the next neuron is called the synapse, or sometimes it is called the synaptic gap or synaptic cleft. But synapse is the common term.
Acetylcholine (ah-Seh-til-KO-leen) is the organic molecule that triggers muscle contractions in humans. Acetylcholine acts on both the central nervous system (CNS) and on the peripheral nervous system (PNS). It is also the principal neurotransmitter in autonomic ganglia.
The leg wouldn't be able to receive or transmit impulses and information from the central nerves system CNS to the muscle and glands
When a signal reaches the end of a neuron it releases neurotransmitters into the synapse where they bind to receptors to release the second messenger into the next neuron.If you are confused I highly recommend this website: http:/learn.genetics.utah.edu/content/addiction/reward/neurontalk.html
Motor unit = the single motor neuron and the multiple muscle fibers that it innervates.
Motor neurons and the muscle fibers they transmit signals toA motor unit is a collection of muscle fibers that contract as a single functional unit when stimulated by an impulse from a motor neuron. The actual size can vary greatly, from many large muscle fibers in the quadriceps muscle group per motor unit to just a few muscle fibers in the muscles of the fingers per motor unit.
This will depend upon the number of muscle fibers the nerve innervates. However, all fibers innervated by the nerve should contract in response to the neuronal impulse.
it is the motor unit
the motor unit
This is called a motor unit.
The neuromuscular junction. A chemical called neurotransmitter is released from a neuron to stimulate the muscle fibers to contract.
