Biology Summary 3.8 The nervous system
The nervous system is made of 2 parts:
- Central nervous system: brain and spinal cord.
- Peripheral nervous system: all the other areas of your body.
Sensory receptors pick up stimuli/ create nerve impulses impulses goes to
the peripheral system transmits to the central nervous system peripheral
picks signals from the central transmits them to effectors creates a
response.
The brain is divided into 3 major parts
Cerebrum: largest part of the brain. Thinking takes place and memories
are stored.
Cerebellum: maintains balance. Coordinates your movements using
information from your eyes, ears, muscles and tendons.
Brain stem: connects the brain to spinal cord. Controls automatic
functions; breathing, blood pressure and heartbeat.
The spinal cord connects the brain
with the peripheral nervous system.
It’s located in the bones of the spine.
