Terms in this set (19)

structures of endocrine system
adrenal cortex secretes hormone that regulate sugar and salt, stress adrenal medulla secretes adrenaline (epinephrine)
adrenal glands
part of peripheral nervous system
regulates heart rate, breathing, blood pressure, etc. (involuntary actions)
broken into sympathetic division and parasympathetic division
autonomic nervous system
neurons located throughout brain and spinal cord
carries information between brain and body
cannot heal when damaged
central nervous system
numerous glands located throughout the body that secrete hormones which affect organs, muscles, and other glands in body
endocrine system
state of increased physiological arousal that a.) directs energy to brain, b.) can be triggered by physical stimuli that threaten survival, or c.) involves responses that prepare fight or flight
activation of sympathetic nervous system
fight-flight response
area at base of brain
controls sleeping, walking, body movements, and vital reflexes
hindbrain
sympathetic and parasympathetic divisions of autonomic nervous system to work together and maintain body's level of arousal in balance for optimum functioning
homeostasis
structure of limbic system
near bottom middle of brain
regulates motivational and emotional behaviors
controls much of endocrine system
regulates pituitary gland
hypothalamus
6 interconnected structures in core of forebrain that influence motivational behaviors
known as primitive/animal brain
limbic system
subdivision of autonomic nervous system that decreases physiological arousal and helps return the body to a calmer state
also stimulates digestion
parasympathetic division
all nerves that extend from spinal cord and carry messages to and from muscles, glands, sensory organs
divided into somatic and autonomic
peripheral nervous system
part of the endocrine system
below hypothalamus
connected by narrow stalk
anterior-controls growth
posterior-controls water and salt levels
pituitary gland
network of nerves connected to sensory receptors or muscles that you can move voluntarily
sensory fibers ->motor fibers
carries information from brain or spinal cord to muscles
somatic nervous system
part of autonomic nervous system
stimulated by threatening situations
sympathetic division
part of limbic system
located in middle of forebrain
receives sensory information, processes it, and passes it on to the cortex
thalamus
