What neurons carry impulses to muscles and glands?

Motor neurons have a long axon and short dendrites and transmit messages from the central nervous system to the muscles (or to glands).

What are motor neurons stimulated by?

When a muscle is stretched, sensory neurons within the muscle spindle detect the degree of stretch and send a signal to the CNS. The CNS activates alpha motor neurons in the spinal cord, which cause extrafusal muscle fibers to contract and thereby resist further stretching.

What is the muscle or gland where motor neuron ends?

They are also called efferent neurons. (v) Effectors are muscles or glands which work in response to the stimulus received from the motor neurons. Explanation: hope this helped you.

Do neurons stimulate muscles or glands?

Explanation: A motor neuron is a nerve cell that conveys impulses from the central nervous system to a muscle or gland. The motor neuron is attached to the muscle fibre at a neuromuscular junction or synapse. The transmission of a nerve impulse to the synapse causes the muscle fibres contract.

What makes the transmission of motor impulses occur?

The transmission is chemical in nature; that is, there is no direct contact between the axon of one neuron and the dendrites of another. The cholinergic nerves ( parasympathetic nervous system) liberate at their axon endings a substance called acetylcholine, which acts as a stimulant to the dendrites of adjacent neurons.

How are motor neurons connected to the central nervous system?

Motor neurons carry information from the central nervous system to organs, glands, and muscles . Sensory neurons send information to the central nervous system from internal organs or from external stimuli. Interneurons relay signals between ​motor and sensory neurons.

Where do chemical and electrical impulses end in the neuron?

These branches end at junctions called synapses. It is at the synapse where chemical or electrical impulses must cross a gap and be carried to the dendrites of adjacent cells. At electrical synapses, ions and other molecules pass through gap junctions allowing for the passive transmission of electrical signals from one cell to the other.

Which is part of the brain carries impulses in the opposite direction?

Those that carry impulses in the opposite direction, away from the brain and other nerve centers to muscles, are called efferent neurons, motor neurons, or motoneurons. Another type, the interneuron, found in the brain and spinal cord, conducts impulses from afferent to efferent neurons. Synapses.
