Somatic nervous system
The afferent nerves of the somatic nervous system carry sensory signals from the skin, skeletal muscles, joints, ears, eyes, tongue, etc. to the central nervous system, while the efferent nerves of the somatic nervous system carry motor signals from the central nervous system to the skeletal muscles.
These neurons connect the CNS to various muscles and glands throughout the body.
what the tree main parts ofthe peripheral nervous system are there
Basically the peripheral nervous system (PNS) consists of all nerves and ganglia which are not in the central nervous system (CNS) which consists of the brain and the spinal cord. The PNS can be divided in to the autonomic nervous system (ANS) which controls involuntary functions such as heart rate and the production of saliva and the somatic nervous system. ANS can be further divided in to two categories called the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS). SNS and PNS are integral in the homeostatic regulation of the bodies functions. The somatic nervous system is associated with the bodies voluntary movements such as those of the skeletal muscles, ie the act of you picking up a pen. It is also associated with receiving external stimuli ie hearing, sight and touch.

The afferent nerves of the somatic nervous system carry sensory signals from the skin, skeletal muscles, joints, ears, eyes, tongue, etc. to the central nervous system, while the efferent nerves of the somatic nervous system carry motor signals from the central nervous system to the skeletal muscles.
The Peripheral Nervous System is made up of 12 pairs of cranial nerves which transmit signals from the joints, skeletal muscles and skin to the brain. The PNS is further subdivided into the Somatic Nervous System and the Viscera.
Motor neurones
The function is to detect and to try to control! The structure is three fold. First, the ANS controls internal functions. Second, the CNS controls the nervous systems. Third, the PNS conveys information about the environment and "output" functions.
These neurons connect the CNS to various muscles and glands throughout the body.
what the tree main parts ofthe peripheral nervous system are there
The somatic nevous system controls voluntary movements while the autonomic nervous system only controls involuntary movements.
They carry instructions from the CNS to muscles, glands, and adipose tissue.
