Releases cortisol, epinephrine, and norepinephrine during fight or flight
Adrenal Gland
Branches extending from the cell body that receive chemical messages via neurotransmitters
Dendrites
Long tube-like extension that sends electrical message (action potential) away from the cell body of the neuron
Axon
Regularly spaced gaps in myelin sheath along the axon that enable ion exchange
Nodes of Ranvier
Extremely narrow space between terminal button of the sending neuron and the receptor site of the receiving dendrite — location of neurotransmission
Synapse
Pleasure, reward, movement, learning, attention
Lack: Parkinson’s
Excess: Schizophrenia
Dopamine
Memory and movement
Lack: Alzheimer’s
Excess: Muscle Convulsions
Acetylcholine (AcH)

Endorphins
Automatic survival functions, send and receive information, damage will result in death

Pons
Survival functions, heartbeat, breathing, digestion, reflexes, sneezing, coughing, vomiting, swallowing
Medulla ❤️
Arousal to stimuli, attentiveness, filters incoming stimuli - damage causes coma
Reticular formation
Smooth voluntary body movements, lack of dopamine hurts and causes Parkinson’s
