nervous system
the bodys speedy electrochemical communication network, consisting of nerve cells of the peripheral and central nervous system
central nervous system
the brain and spinal cord
peripheral nervous system
the sensory and motor neurons that connect to the rest of the body
neural "cables" containing many axons. part of the peripheral nervous system. connects to the central nervous system with muscles glands and sense organs
sensory neurons or afferent
carry incoming information from the sense receptors to the central nervous system
motor neurons or efferent
carry outgoing information from the CNS to muscles and glands
CNS neurons that internally communicate and intervene between the sensory inputs and motor outputs
somatic nervous system
component of the PNS that controls the bodys skeletal system
autonomic nervous system
part of PNS that controls the glands and muscles of the internal organs like the heart
sympathetic nervous system
division of the ANS that arouses the body, mobilizing its energy in stressful situations
parasympathetic nervous system
division of the ANS that calms body conserving its energy
sympathetic and parasympathetic nervous system
2 divisions of the autonomic nervous system
somatic and autonomic nervous system
2 components of the PNS
our automatic response to stimuli. a simple, automatic, inborn response to a sensory stimulus
neural network
interconnected neural cells, with experience networks can learn, as feedback strengthens or inhibits connections that produce certain results
tissue destruction, this is a naturally or experimentally caused destruction of brain tissue
edoctrine system
set of glands that secrete hormones into the blood stream. it is the "bodys snail" "slow" for the body so like 1 second
chemical messengers that are produced in one tissue and affect another, similar in structure to neurotransmitters. when acted on brain they influence our interests for sex, food, and aggression. travel in the blood
adrenal glands
located right above the kidney, release epinephrine and norepinephrine. increase heart rate, blood pressure, and blood sugar giving us a surge of energy, helps to arouse the body in times of stress. works with the sympathetic NS
pituitary glands
endoctrines systems most influential. produces of controls release of many different types of hormones. located under the hypothalamus which controls it
adjacent brain area to pituitary glands and controls it
adrenal glands, pituitary glands
parts of the endoctrine system that control hormones
