1

Functions of the nervous system

Sense external and internal environments, integrate sensory information, coordinated involuntary and voluntary activities
Control prefor effectors

2

What somatic system controls is

Skeletal

3

Automatic nervous systems

Involuntary

4

Basic functions of a unit is called

Neuron

5

Axon parts

Axon hillock connects axon to cell body

6

Synapse is side of

Communications

7

Because lack of anturals the central nervous system the

Neurons can’t divide

8

Ineral receptors that monitor are

Inside

9

Proceral receptors position for

Joints

10

Bi polar

One axon one dentrite

11

Multi polar (most common)

One axon many dentrites

12

Neuron cell body of peripheral nervous system are clustered in

Ganglia

13

Astrocite functions

Maintain the blood-brain barrier, absorb access neuro transmitter, respond to neuro damage and form 3 deminition framework of central nervous system

14

Alegondeno cites

Make up mythlon seeth of central nervous system

15

Microgleia

Are fegocites

16

White matter

Mylonated

17

Gray matter

Unmylonated

18

Statilite cells

The Gleno cells in the peripheral nervous system

19

When electrical and chemical forces together it is

Electrical chemical radiant

20

Absolute fractory period

When action potential begins until another action potential is enicasted

21

Minimal stimulus

That triggers action potential is called threshold

22

Continuous propagation

Goes all entire length

23

Posterior root ganglia

Contains sensory neurons

24

31 spinal cord segments for spinal nerves they contain

Sensory and motor neurons

25

Coste megliajs

Ends in L1

26

Dura matter

Outer most

27

Pea mater

Direct contact with spinal cord

28

Cerebral spinal fluid is in the

Suberacnode space

29

Subderal space is

Dura and eraconde

30

Cover nerve outer most

Epenerium

31

Surrounds facial

Paraneium

32

Surrounds individual axons

Endonarium

33

Anterior horns are

Somatic motor

34

Posterior root ganglia is posterior

=sensory

35

If stubborn won’t get

Sensory input

36

Sensory information carried to spinal cord or interior ramps if

Brushed against aboudmen

37

Cervical plexus

Supplies in for to diphram

38

Nerve plexus is interwoven work

Of nerves

39

Fretic nerve interfates the

Diaphragm

40

If injury C3 C4 C5 it might be hard to

Breath

41

The breakale plexus has

C4-T1 nerves

42

Allner nerve is included as long as radial, median and muscles contain

Static nerve

43

Is formed from fibular nerve and tibular nerve that is coxagel plexus

Static nerve

44

One synapses to servers post sepatic

Divering pool

45

Actually extends back towards the impluse

Reverberation

46

Are based on synapis form during development

Inate telex is

47

Different types of reflexes

Intersegmental, polysnaptic, and ansomatic

48

Goes from sensory to motor neuron directly

Monosonaptic

49

Is important to regulate muscle length

Stretch reflex

50

Are intersegmental involve recenitcial renivation, involve pools of inner neurons and have reverberating circuits

Polysonatic reflexes

51

Complents the flexor reflex

Cross extensor reflex

52

Iperlateral

Reflex on same side

53

Conserlateral

Opposite sides

54

Rapid automatic response to a trigger to a specific stimuli

Reflex

55

Located between Cerberum and brain stem

Diasefalon

56

Located floor of diaseflon

Hypothalamus

57

Sensory information is processed in the

Thalamus

58

Autonomic center controls

Blood pressure, heart rate, digestion

59

Medulla

3rd of dualamagata
3rd and 4th meteicals lengthed by clender canal called ceberal aqueduct

60

Where cerebral spinal fluid is located

Subarachnoid space

61

What makes cerebral spinal fluid in corderode plexus

Epedimal cells

62

Ascending CElls

Carry sensory information

63

Descending Carries

Motor information

64

Medulla magata

Controls heart rate

65

Crossing over

Decusation

66

Auditory

Located in temporal lobe

67

Coordinate muscle responses

Association areas

68

Pre frontal cortex

Responsible for predicting consequences of events or actions

69
