Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the function of the motor neurons?
A
they get information about what happens inside and outside the body
B
connect one neuron to another neuron in the central nervous system.
C
they get information from the dendrites
D
they get information from other neurons and sends commands to muscles
Explanation: 

Detailed explanation-1: -Motor neurones are cells in the brain and spinal cord that allow us to move, speak, swallow and breathe by sending commands from the brain to the muscles that carry out these functions. Their nerve fibers are the longest in the body, a single axon can stretch from the base of the spinal cord all the way to the toes.

Detailed explanation-2: -Motor neurons of the spinal cord are part of the central nervous system (CNS) and connect to muscles, glands and organs throughout the body. These neurons transmit impulses from the spinal cord to skeletal and smooth muscles (such as those in your stomach), and so directly control all of our muscle movements.

Detailed explanation-3: -The motor neuron plays a role in the movement, including voluntary and involuntary movements this neuron allow the brain and spinal cord to communicate with muscles, organs, and glands all over the body.

Detailed explanation-4: -Motor neurons are also known as efferent neurons, meaning they carry information from the CNS to muscles, and other peripheral systems such as organs and glands. This contrasts with afferent neurons, or sensory neurons, which carry information from sensory organs and tissues back to the CNS.

Detailed explanation-5: -Sensory cells carry afferent impulses to a central interneuron, which makes contact with a motor neuron. The motor neuron carries efferent impulses to the effector, which produces the response.
