Flashcards in Chapter 3 - Neuroanatomy Deck (24):
1

 Major divisions of the human nervous system (including the subsets of the PNS)

2

 Afferent vs. efferent nerves

Afferent information
  
  efferent nerves
   go from the brain out THEY EXIT

3

Sympathetic vs. parasympathetic nerve functions

4

 The 3 Meningeal layers

Dura MAter

Arachnoid MAter

Pia MAter

5

 Purpose of the blood-brain barrier

 essentially a barrier that allows some substance through but not all
   phospolipid bylayer

**The brain does not conform to the skull but floats in the skull in the blood brain barrier**

6

 Functions of the ventricles

fluid filled cavities deep within the brain.
brain develops from these ventricles
filled with cerebrospinal fluid (Na Cl Glucose O2)
cushions the brain
carries toxings from the brain

7

 Cerebrospinal fluid composition and functions

Na Cl Glucose O2

cushions the brain
carries toxings from the brain

8

 Directional terms in animals and humans (i.e. medial/lateral, etc...)

9

 White vs. gray matter

grey is cell modes and is unmyleinated
White is indicative of axons and is myelinated

10

 The 5 divisions of the human brain

Myelincephalon

diencephalon

metenchepalon

telenchepalon

mesencephalon

11

 The 4 major cerebral lobes

frontal

parietal 

occipital

temporal

12

 General functions of the Thalamus 

(RELAY STATION FOR SENSES)
  sensation and perception
  sensory rely station for all of your sense (all sense pass through this deep part of    your brain) ex. vision traveling from eyes goes through thalamus then on to the    occipital lobe

13

What is the CNS composed of

THE BRAIN AND THE SPINE

14

WHAT IS THE PNS COMPOSED OF

SOMATIC NERVOUS SYSTEM

AUTONOMIC NERVOUS SYSTEM

15

WHAT IS THE SOMATIC NERVOUS SYSTEM

system of nerves that interacts with ones environment
  relay info to and from the CNS
  Afferent information
  
  efferent nerves
   go from the brain out THEY EXIT

16

AUTONOMIC SYSTEM

regulates that bodys internal environment
  2 types of nerves that communicate motor info out
   Sympathetic-stress- (spine) (scared) and parasympathetic-rest and restore- (located at the cranial and sacral regions nerves
  homeostasis-balance

17

What are the two layers of the Dura Mater

1. peristeal layer
   2.  meningeal layer

18

What is the function of the choroid plexus

distills cerebrospinal fluid from the blood

19

Nuclues

 collection of neural cell bodies

20

Fasiciculus

a bundle of nerve fibers

21

funiculus

an area of white matter

22

tract

a bundel of nerve fibers inside the cps

23

commissure

a crossing of fibers from one hemisphere of the brain to the other

24

general functions of the Hypothalamus as described in lecture

small
  regulates our bodily cycles (NOT BREATHING OR HEARTBEAT)
  circadian rhythms
  Maintains homeostasis
  connected to the pituitary gland (hypothalamus controls the endocrine system via   the pituitary gland)
