Organising The Nervous
System
- Responding to the Environment
- All organisms need a method of
communication between their
sensors and effectors.
- Subdividing the Nervous
System
- The nervous system
coordinates the actions
of the body through
electrical impulses
- It works in conjunction with the endocrine system.
- Structurally
and
functionally
divided into
subsystems
- Central nervous system and peripheral nervous system
- The CNS consists of the
brain and spinal cord.
- It is made up of grey matter
(billions of non-mylelinated nerve
cells) and white matter (longer,
mylelinated axons and dendrons
that carry impulses.
- The peripheral nervous system is
made up of theneurones that carry
impulses into and out of the CNS
