NEUROTRANSMITTERS nerves terminal in the spine, brain stem, thalamus, and hypothalamus, pituitary gland
Enkephalin, endorphin
26
NEUROTRANSMITTERS type.... pleasurable sensation, inhibits pain transmission
excitatory enkephalin endorphin
27
2% of the total body average young adult (1400g) average older adult (1200g)
Brain
28
brain dividef into 3 major organs
cerebrum brain stem cerebellum
29
85% of the brain tissue largest and most developed part of the brain
cerebrum
30
is the great longitudinal fissure that separates the cerebrum into the right and left hemisphere
cerebral hemisphere
31
external or outer portion of the hemisphere innermost layer
gray matter white matter
32
composed of 2 hemisphere
thalamus and hypothalamus
33
cerebral hemispheres are divided into pairs of lobes
Frontal Parietal Temporal Occipital
34
largest lobe
frontal
35
concentration, abstract thought, information storage, or memory and motor function
Frontal
36
Broca Area - left hemisphere and us critical for motor control of speech
Frontal
37
also responsible in large part for a person's effect, judgment personality and inhibitions
frontal
38
critical thinking personality motor activity
frontal
39
analyzes sensory information to other cortical areas and is essential to a person's awareness of body position in space, size and shape discrimination
parietal
40
right lefr orientation
parietal
41
discrimination of sensory impulses to pain, touch, pressure heat and cold
Parietal
42
responsible for visual interpretation and memory
occipital
43
contains the auditory receptive areas
temporal
44
plays in memory of sound and understanding of language and music
temporal
45
hearing and sound short term memory
temporal
46
thick collection of nerve fibers that connects the two hemisphere of the brain responsible for the transmission of info from one side of the brain to the other
corpus callosum
47
verbal, linguistic, arithmetic, calculation and analytical functions
cerebral dominance of the left side of the brain
48
geometric, spatial, visual, pattern and musical functions
nondominant hemisphere
49
integrates sensory information to provide smooth coordinated movement control fine movement, balance and position (postural) sense or proprioception (awareness of positionof extremities w/o looking at them
cerebellum
50
Function: Smell (sensory) Key Role: Detects odors
Olfactory (I)
51
Function: Vision (sensory) Key Role: Transmits visual information.
Optic (II)
52
Function: Eye movement, pupil constriction (motor) Key Role: Controls most eye muscles, eyelid elevation, and pupil response.
Oculomotor (III)
53
Function: Eye movement (motor) Key Role: Controls the superior oblique muscle (downward and inward movement).
Trochlear (IV)
54
Function: Facial sensation, chewing (mixed) Key Role: Provides sensation to the face and controls jaw muscles.
Trigeminal (V)
55
Function: Eye movement (motor) Key Role: Controls the lateral rectus muscle (eye abduction).
Abducens (VI)
56
Function: Facial expression, taste (mixed) Key Role: Controls facial muscles, taste (anterior 2/3 of tongue), and some salivary glands.
Facial (VII)
57
Function: Hearing, balance (sensory) Key Role: Transmits sound and equilibrium information.
Vestibulocochlear (VIII)
58
Function: Taste, swallowing (mixed) Key Role: Taste (posterior 1/3 of tongue), salivation, and pharynx sensation.
Glossopharyngeal (IX)
59
Function: Autonomic control, swallowing (mixed) Key Role: Regulates heart rate, digestion, and respiratory functions; controls voice and swallowing muscles.
Vagus (X)
60
Function: Neck and shoulder movement (motor) Key Role: Controls sternocleidomastoid and trapezius muscles.
Accessory (XI)
61
Function: Tongue movement (motor) Key Role: Enables speech and swallowing.
Hypoglossal (XII)
