-TYPES- OF NEURONS

Types of neurons

Multi ‘ polar constantly referring

Uni polar

Bi Polar

MULTI POLAR neuron com. In CNS mostly MOTOR neurons

One axon, TWO or MORE DENDRITES

One terminal end

Ex- ALL SOMATIC MOTOR NEURONS that control the SKELETAL Muscles

Bi polar neurons (rare)

2 PROCESSES each side of cell body

One axon, ONE DENDRITE

Found in the OLFACTORY EYE and in SMELL

Dendrites and axon on either ends both

Soma in middle

Uni Polar are SENSORY neurons of the pNS

Axon and Dendrites are FUSED

Dendrites with axon right next to end soma in middle

Before soma is PNS

After soma deals with CNS

Cell body closer to CNS

Only one process that connects both dendrites and terminal ‘ communication

PNS —- soma ——— CNS

INTERNEURONS

Are BRANCHED OUT of the types of Neurons

They lie BETWEEN sensory and motor neurons

RESPO. For picking up info from the sensory (uni polar), INTERPRETING , and then sending to MOTOR neurons (multi polar)

Efferent - sensory - uni

AFFERENT - motor - multi

(Extra step, middle men, interpreting, sometimes you need it sometimes you don’t)

Uni polar - int. - Multi polar

Sensory - int - motor response

Effector int to affector
