Flashcards in Lecture 9 Pt II Deck (16):
1

Neurons (Body(

Contains nucleus, mitochondria, ect.

2

Neurofibrils

Bundles of proteins (neurofilaments) that aid in rapid communication and transport

3

Dendrite

Branching processes., terminate with receptors. receiving structure.

4

Axon

Single process attached to the body by the acon hillock. terminated with telondendria with synaptic knobs. sending structure.

5

Myelin Sheath

created by schwann cells. contains myselin sheath gaps.

6

Input zone

dendrites and cell body

7

Summation zone

axon hillock

8

Conduction zone

axon

9

Output zone

telondria and synaptic knobs of axon.

10

Multipolar

One axon and multiple dendrites. most common

11

Bipolar

one axon and one dendrite. Ex. olfactory neurons.

12

(Pseudo)unipolar

one axon with a dendrite end. always sensory. (Afferent)

13

Functional Classifications of Neurons

Afferent, interneurons, efferent

14

Epineurium

fibrous coat surrounding entire nerve

15

perineurium

surrounds and binds fascicles

16

endoneurium

surround individual nerve fibers
