Psych test 2

study of biological processes and behaviors

study of the nervous system

communicates through the nervous system

provide nutrition, removes dead neurons

convey info, such as light, sound and touch

convey info to muscles for movement

connects one neuron to another

(communicates from one neuron to another)

provides energy and nutrients for the neuron

small hairs attached to cell body that receive info, from other neurons

long tube that carries info, to muscles, glands and other parts of the body

insulates the axon to increase communication speed

brief electrial impulse that transmits information along the axon

minimum level required to activate a neuron

state in which neuron is ready activate if sufficant stimulus is received

sufficient stimulation has to happen for the action potiential to take place

point of communication between neurons

tiny space between the axon terminal and dendrite of an adjoining neuron

branches at the end of axon with tiny pouches and synaptic vesicles

tiny pouches at the end of an axon, contains neruotransmitters

chemical messages sent by neurons.

process by which neurotransmitters affect other neurons

recycling of neurotransmitters that failed to attach to recepter cite

learning, memory, muscle contractions,

movement, thought processes, rewarding sensations

emotional states, sleep

inhibition of brain activity

pain perception, positive emotions

central nervous system

cerebrospinal fluid to protect the brain from being jarred

spinal column

body network divided into central nervous system and peripheral nervous system

all nerves laying outside of CNS (somatic nervous system)

simple automatic behavior processed in the spinal cord

regulates heartbeat, breathing, and digestion

made up of glands that secrete chemicals called hormones

regulate growth, metabolism, digestion adn sexual development

growth

regulates stress. adrenal medulla, adrenal cortex

sex organs, ovaries in women, testes in men

• medulla
• forebrain
• cerebral cortex
• cerebral hemispheres
• corpus callosum
• temporal lobes
• occipital lobes
• parietal lobes

negative, emotional state occuring in response to events that are percieved as taxing or exceeding a persons resources or ability to cope

the branch of psychology that studies how biological, behavioral, and social factors influence health, illness, medical treatment, and health-related behaviors

the belief that physical health and illness are determined by the complex interaction of biological, psychological, and social factors

everyday minor events that annoy and upset people

a situation in which a person feels pulled between two or more opposing desires motives, or goals

2 appealing decisions

2 unappealing decisions

1 appealing 1 unappealing decision

a rapidly occuring chain of internal physical reactions that prepare people either to fight or take flight from an immefiate threat

hormones secreted by the adrenal medulla that cause rapid physiological arousal; include adrenaline and noradrenaline

hormones released by the adrenal cortex that play a key role in the bodys response to long-term stressors

body system that produces specialized white blood cells that protect the body from viruses, bacteria, and tumor cells

specialized white blood cells taht are responsible for immune responses

an interdisciplinary field that studies the interconnections among psychological processes, nervous and endocrine system functions, and the immune system

accounting for negative events or situations with external, unstable, & specific explanations

accounting for negative events or situations with internal stable and global explanations

stress of moving to a different state or country and adapting to that culture

alarm stage, resistance stage, exhaustion

the resouces provided by other people in times of need

behavioral and cognitive responses used to deal with stressors; involves our efforts to change circumstances, or our interpretation of cirumstances, to make them more favorable and less threatening

coping efforts primarily aimed @ directly changing or managing a threatening or harmful stressor

coping efforts primarily aimed at relieving or regulating the emotional impact of a stressful situation

• 1. avoid or minimize the use of stimulants
• 2. exercise regularly
• 3. get enough sleep

hearing

sight

sensory functions

speech and memory functions, thinking, emotional control

breathing and circulation
