Question

The axons of lower motor neurons project out of the spinal cord (via the ventral nerve roots), becoming part of the spinal nerves. These cells synapse onto skeletal muscles throughout your body, controlling whether or not they contract in response to voluntary motor commands generated in the cerebral cortex. Thus, these cells can be classified as -

A the somatic nervous system.

B efferent.

C the parasympathetic nervous system.

D sensory neurons.

E part of the PNS.

F effector neurons.

G part of the CNS.

H interneurons.

I the sympathetic nervous system.

J afferent.

Explanation / Answer

The somatic nervous system: It is the portion of the peripheral nervous system that control voluntary control of body movements. Efferent neurons: transmit neural impulses away from the central nervous system . Also known as motor neuron. The parasympathetic nervous system: is a part of autonomic nervous system. It is required for rest-and-digest" or "feed and breed" activities in human body. Sensory neurons: They are the nerve cells required for changing external stimuli from environment of the organisms to internal electrical impulses. Part of the PNS: Two important part of PNS include somatic nervous system and autonomic nervous system. Effector neurons: is responsible for the transmission of impulses that originate in central nervous system and reaches to an effector resulting a physiological response with respect to changes in the environment. Part of the CNS: consist of brain and spinal cord. Interneurons: transmit signals among sensory neurons, and motor neurons. The sympathetic nervous system: is a portion of autonomic nervous system Afferent: these are neurons that transmit signal from sensory stimuli to the cental nervous system.
