25
consists brain and spinal chord
Central Nervous System
26
consist of cranial nerves (12pairs) and Spinal Nerves (31 pairs)
Peripheral Nervous System
27
Division of Peripheral Nervous System
Somatic and Autonomic
28
From receptors of limbs/body/head to CNS then CNS to skeletal muscles
Somatic Nervous System
29
sensory impulse from visceral organs to CNS then CNS to cardiac,smooth muscles and glands
Autonomic Nervous System
30
Division of Autonomic Nervous System
Sympathetic and Parasympathetic
31
prepare the body for “E” situations (emergency,exercise, energy expenditure)
Sympathetic Nervous System
32
fight/flight
sympathetic nervous system
33
prepare the body for res recovery and healing
parasympathetic nervous system
34
rest and digest
parasympathetic nervous system
35
detect stimulus (generate nerve impulse)
Receptors
36
receptors to CNS
Afferent ( Sensory Neurons)
37
process sensory information and decide on motor Response
CNS
38
CNS to Effectors
Efferent (Motor Neurons)
39
muscle/glands that alter their activity
Effector
40
rapid, predictable sequence of involuntary actions that is a response to particular stimulus
Reflex
41
is the nervous system pathway followed by nerve impulse to produce a response
reflex arc
42
Region of the brain
Cerebrum, Cerebellum , Brain stem
43
has many convolutions which effectively triple its surface area
Cerebrum
44
80 % of brain mass
Cerebrum
45
initiate voluntary motor activity
Cerebrum
46
analyze information for thinking and learning
Cerebrum
47
part of the brain that store memories
Cerebrum
48
highly folded surface
Cerebellum
49
provide smooth, coordinated skeletal muscle movements
Cerebellum
50
regulates posture and maintains balance subconsciously
Cerebellum
51
part of the brain that connects to the spinal chord
Brainstem
52
has center for controls of basic functions for survival (cardiac and respiratory)
Brainstem
53
Lobes of the Cerebrum
Parietal, Frontal, Occipital, Temporal
54
lobe that contains primary sensory cortex
Parietal Lobe
55
lobe that control conscious awareness of sensation
Parietal Lobe
56
Lobe that contains the motor cortex for control of skeletal muscle movement
Frontal Lobe
57
Lobe that process emotion related to personal and social interaction
Frontal Lobe
58
Lobe that involved in problem solving and learning
Frontal Lobe
59
Lobe that includes the visual cortex
Occipital Lobe
60
Lobe that controls smell, hearing and tase
Temporal Lobe
