the nervous system comprises three major types of neurons: sensory neurons, interneurons, and this
the part of the autonomic nervous system is thought of as the "fight or flight" system
this is a thin "bark" of neurons in the forebrain that is thought to be the most evolved of brain regions
the insulation around axons made of glial cells that allow for faster transmission of nerve impulses and is also called the "white matter" in the brain; MAKES NERVE IMPULSE MOVE FASTER/MORE EFFICIENT
this NT is involved in mood regulation, aggression, sleep, and is involved in eating disorders, OCD and depression
a part of the forebrain that is associated with emotion, memory, and goal-directed behavior; includes the hippocampus and the amygdala
the result of positively charged sodium ions entering a neuron followed by positively charged potassium ions flowing out
generate electricity that creates nerve pulses; building blocks of nervous system; release NTs
most common 1 of 2 NT; rapidly excites neurons, increasing likelihood of communication; associated with learning and memory and schizophrenia
most common 2 of 2 NT; main inhibitory NT dampening neural activity; anti-anxiety meds bind to GABA receptors; associated with learning, memory, and sleep
NT associated with muscle contraction, cortical arousal, selected attention, sleep, memory
NT associated with brain arousal, mood, hunger, sleep, depression, stress, panic disorders
NT associated with emotional arousal, risky behavior, motor function, Parkinson's disease, depression, Schizophrenia
NT associated with mood, body temp, aggression, sleep cycles, depression, eating disorders, OCD
b. spinal cord
Peripheral N. Sys:
senses body's internal functions, controls glands, controls smooth muscles of hear, blood vessels, stomach, intestines
2 largest hemispheres; outer portion of forebrain; HIGHLY INVOLVED WITH THINKING, LEARNING, EMOTIONS
