Flashcards in 4 Types of Neurons Deck (11):
1

Multipolar Cells:

structure: MANY cell processes, ONE axon, MULTI dendrites
Function:motor neurons for voluntry/involuntarymovement

interneurons form fiber tract tat links b/w brian & spinal cord regions

2

Multipolar Cells Locations:

cerebral cortex
cerebellar cortex
gray matter in spinal cord

3

Bipolar Cells:

Structure: 2 cell processes, one axon, one dendrite
Function:sensroy neurons for vision, hearling, balance, smell

4

Bipolar Cells Locations:

retina of eyes
inner ear
olfactory epithelium in nasal cavity

5

Unipolar Cells:

Structure: one cell processes that divides into 2 branches

BOTH branches are axons

The receptive endings of peripheral branch re dendrites

6

Unipolar Cells Functions:

Sensory neurons for general: touch. temperature, pain,

7

Unipolar Cells Locations:

sensory ganglia for spinal nerves
most cranial nerve ganglia

8

Anaxonic Cells:

Many cell processes, ALL are dendrites
Function: unknown
Locations: various regions of the brain

9

Afferent:

signals travel from neurons of the body to the CNS

10

Efferent:

Exits the CNS to go to neurons of body

11

Neurolia/Glial Cells:

Perform a variety of functions
that protect/support neurons & other structures
small bodies & cytoplasmic processes extend from

Found in CNS & PNS
