1
Functions of the nervous system

Control prefor effectors
2
What somatic system controls is
Skeletal
3

Involuntary
4

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

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
White matter of cerebellum
Arbor vitae
70
Cerebellum
Oversee’a posterior muscles to make rapid adjugment to maintain balance to liberium
71
Gives us movement toward allow Noise
Inferior colicuili
72
Comes from darkley pigmated cells
Substantia nijerua
73
Reticular activating system
Controls alertness and attention
74
Connects hypothalamus to Brain stem (patertary glands)
Infedeulum
75
Provides blank between enocrine and nervous system
Hypothalamus
76
Thalamus
Process information to sensory info
77
Responsible for visual info and media ovitory

78
Lembic system
Control emotional content of brain
79
Regulate patterns and movements
Neucli
80

Occipital lobe
81
Highest level of info process
Cerebrum
82
Allow us to interput what we read
General interput
83
Intergrated center
Receive info from asssociate areas and direct extremely Moto contact activities (like speech)
84
