Does the motor neuron send a signal to or from the muscle fiber?

Sensory Neuron sends info to the brain while the motor sends the info to the muscle fiber.
The motor neurone sends a signal from the CNS or PNS to the effector muscle or gland. Therefore the motor neurone sends a signal TO the muscle fibre.

The motor neuron and the muscle fiber it controls constitute a what?
Motor Unit :)
The synapse of a motor neuron with a muscle fiber is known as the what?
neuromuscular junction
What is the function of the neuromuscular junction is to?
Includes the axon terminal of a motor neuron plus the motor end plate of a muscle fiber. Is where the axons of motor nerves meet the muscle & transmit messages from the brain which cause the muscle to contract & relax.
Skeletal muscle fiber is controlled by a motor neuron at a single?
Each muscle cell is only innervated by a single motor neuron, but each motor neuron innervates any number of muscle cells. When an action potential travels down the axon of an alpha motor neuron, it will depolarize several muscle cells at the same time, a phenomenon known as summation.
Chemical released to stimulate muscle contraction?
A signal is generated in the motor cortex of the brain, and travels down the spinal cord to the affected motor neurons. As the action potential travels down the axon of the final motor neuron, it causes calcium influx and exocytosis of acetylcholine-containing vesicles, releasing acetylcholine into the neuromuscular junction. From there, acetylcholine binds with receptors on the muscle fiber end plates, where it depolarizes the muscle fiber, causing contraction of the muscle.
A motor neuron together with the muscle fiber it innervates?
it is the motor unit

The point of contract between the nerve ending and the muscle fiber is called a motor neuron?
Neuromuscular junction (NMJ)
What is a motor neuron attached to?
A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.
What is the name of a neuron that transmits a neural impulse from the central nervous system through the spinal cord to a muscle?
The neuron that transmits a signal from the nervous system to an effector is a motor neuron.
Which two structures approach each other at a neuromuscular junction?
The motor neuron and the muscle fiber approach each other.
