Control System of the Body




DEFINITION
Nervous tissue is the term for groups of organized cells in the nervous
system, which is the organ system that controls the body’s movements,
sends and carries signals to and from the different parts of the body, and
has a role in controlling bodily functions such as digestion.

FUNCTION OF NERVOUS TISSUES
Coordinates information from all areas of the body and sends
nerve impulses that control all bodily movements
Connects the CNS to the rest of the body and is directly
responsible for controlling movements of specific parts of the
body

DIVISION OF NERVOUS SYSTEM
There are two division:
Central nervous system (CNS) is the brain and spinal cord, it coordinates
information from all areas of the body and sends nerve impulses that control all
bodily movements
The peripheral nervous system (PNS) is everything else. It connects the CNS to
the rest of the body and is directly responsible for controlling movements of
specific parts of the body; for example, just before arm movement the CNS sends
nerve impulses to the PNS nerves in the arm, which causes the arm to move.
