Input from sensory organs to brain & spinal cord
Output from the brain & spinal cord to muscles & glands
Carry info. Between other neurons (only found in brain and spinal cord)
Functions Surplus DeficitDopamine Influence: Movement, Learning, Attention, and Emotion Parkinson's Disease Depression
Serotonin Affects: Mood Hunger, Sleep, and Arousal Sleepy Violence, Depression, and Anxiety
Norepinephrin Helps control: Alertness and Arousal Happiness Depression
GABA Inhibitory Neurotransmitter Relaxation, loopyness Seizures, Insomnia, and Anxiety
Glutamate Memory Injures brain cells Causing MS
Acetylcholine(ACh)Muscle Contraction paralysis, Convulsions, or Death Memory impairment Alzheimer’s
Endorphins Released in response to: Pain and Exercise “Runner’s High” Happiness 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 skullMedulla: base of brain stem, heartbeat & breathingReticular Formation: between ears spinal cord to thalamus, arousalThalamus: top of brainstem, sensory switchboard- not smellCerebellum: back of brain, voluntary movement & balance
Amygdala- almond shaped, aggression & fear Hypothalamus - bellow thalamus, eating drinking body temp. reward centersPituitary gland – pea sized base of brain, controls endocrine system
Hormones – chemical messengers, produced in one tissue and effect anotherAdrenal Gland – above kidneys, release epinephrine & norepinephrine is stressful situationsPituitary gland – pea sized base of brain, controls endocrine system
