Motor
Sensory
Interneuron
Input from sensory organs to brain &
spinal cord
Carry info. Between other
neurons (only found in brain and
spinal cord)
Output from the brain & spinal cord
to muscles & glands
Functions
Dopamine Influence: Movement, Learning,
Attention, and Emotion
Serotonin Affects: Mood Hunger, Sleep,
and Arousal
Norepinephrin
GABA
Helps control: Alertness
and Arousal
Inhibitory Neurotransmitter
Glutamate
Memory
Surplus
Deficit
Parkinson's Disease
Sleepy
Depression
Violence, Depression, and Anxiety
Happiness
Relaxation, loopyness
Depression
Seizures, Insomnia, and Anxiety
Injures brain cells Causing MS
Acetylcholine(ACh)Muscle Contraction
paralysis, Convulsions,
or Death
Endorphins Released in response to:
Pain and Exercise
“Runner’s High” Happiness
Memory impairment Alzheimer’s
Emotional, Crying,Chronic pain
Central nervous system(CNS) – Brain and
Spinal cord
Peripheral nervous system(PNS) – links CNS
with body’s sense receptors, muscles and
glands
Left: Language
Right: Math
&Music
Back of head, Optic nerve SIGHT
Sides of head above ears, Auditory cortex
HEARING –speech, facial, word recognition
& memory formation
Back top of head, hand-eye coordination,
Front of head, working memory, motor cortex
Brainstem: where spinal cord swells as it enters
skull
Medulla: base of brain stem, heartbeat & breathing
Reticular Formation: between ears spinal cord to
thalamus, arousal
Thalamus: top of brainstem, sensory switchboardnot smell
Cerebellum: back of brain, voluntary movement &
balance
Amygdala- almond shaped,
aggression & fear
Hypothalamus - bellow thalamus,
eating drinking body temp. reward
centers
Pituitary gland – pea sized base
of brain, controls endocrine system
Hormones – chemical messengers,
produced in one tissue and effect
another
Adrenal Gland – above kidneys,
release epinephrine &
norepinephrine is stressful
situations
Pituitary gland – pea sized base of
brain, controls endocrine system
CAT- X-ray scan, shows brain
structure, cross-sectional views of all
tissue
PET- Cellular function of human
body
MRI- (magnetic resonance imaging)
uses magnetic and radio waves no
Radiation, Bones turn out dark all
tissue showed, Brain and spinal cord
