Functions of the Nervous
System
1. Sensory- Monitors changes that
occur inside and outside of the body.
2. Integrative- Processes information
coming in, makes decisions, and
stores information.
3. Motor- Sends signals back to body
causing it to respond appropriately.
Neurons


The nervous system (NS) is made out of cells called
neurons.
A neurons 3 Basic Parts (Like a phone?)
– Dendrites- Receive messages.
– Cell Body- Contains nucleus, controls cell.
– Axons- Send messages.
Neurons

3 Basic Types
– Sensory- Bring information from
your body or surroundings to your
spinal cord (SC) and/or brain.
– Motor- Send info from brain or SC
to muscles or glands.
– Interneurons- Connect Sensory and
Motor Neurons
Receptors


Specialized cells that sense a
particular stimulus and begins the
signal from the outside world into your
NS.
Humans have 4 types:
– Movement
– Light
– Temperature
– Chemical
Stimulus
Plural Stimuli
