Flashcards in Intro to Neuro DOCX Deck (15):
1

What is gray matter?

Consists of nerve cell bodies & neuroglia.
Has cerebral cortex and Nuclei.

2

Cerebral Cortex is

Brain bark, is multiple layers of nerve cell bodies & neuroglia that form a sheeh

3

Nuclei

A nucleus is a collection of nerve cell bodies & neuroglia w/in the CNS

4

What is white matte?

Consist mainly of myelinated nerve cell axons & neuroglia.
Also has tracts, peduncles & commisures.

5

Tracts in the NS are

Bundle of axons
Fasiculus - bundle
Lemniscus - ribbon
Brachium - arm

6

Peduncle is

Foot like process

7

Commisures are

Decussating/crossing axons
Anterior
Posterior
Olfactory
Corpus callosum

8

Cutaneous n.

skin receives sensory & autonomic inn.

9

Nerve fiber

refers to a dendrite or axon of a neuron

10

Pathways of NS

2 or 3 neurons relay particular information of modalities or motor fx

11

Sensory p/w

relays sensory input

12

Motor p/w

Brain to muscle motor info

13

What is a decussation?

Oblique crossing of axons from one side to other side of CNS.

14

Commisural fibers are

Axons that arise from one side of brain or spinal cord and cross to other side.

15

Association fibers are

Axons that connect the different parts of the same hemisphere.
