axon

long fiber that carries electrical impulses away from the nerve cell body

glucose

simple sugar that is used to make ATP through cellular respiration

insulin

hormone from the pancreas that decreases blood sugar by signaling the liver to store glucose

circulatory system

body system consisting of the heart and blood vessels that circulate blood through the body

kidneys

organs that filter nitrogen wastes from blood to make urine

liver

organ that regulates blood sugar by storing or releasing glucose; makes bile to break down fats; filters poisons out of the blood

excretion

elimination of wastes from the body (urine, carbon dioxide, sweat)

spinal cord

cord of nerve tissue that conducts messages between the brain and the peripheral nerves

sensory neurons

neurons that carry sensory information from receptors to the central nervous system

motor neurons

neurons that carry outgoing information from the central nervous system to the muscles and glands

neuron

nerve cell; conducts electrical signals

endocrine system

collection of glands that secrete hormones into the blood which regulate growth, development, and homeostasis

hormone

chemical messengers secreted by glands into the blood

gland

an organ that secretes hormones into the bloodstream

nervous system

consists of brain, spinal cord, and nerves and regulates the body's responses to internal and external stimuli

homeostasis

the process by which organisms keep their internal environment relatively stable

negative feedback loop

an opposite action to what is occurring in the body to regain homeostasis, ex. if body temperature rises too high, body tries to lower it

dendrites

part of a neuron that carries the electrical impulse to the cell body

nerve

bundle of neurons surrounded by connective tissue

synapse

where two adjacent neurons meet

neurotransmitter

chemical messenger sent across a synapse which allows two neurons to communicate

glucagon

hormone from the pancreas that raises blood sugar by signaling the liver to release glucose

glycogen

long chain of glucose molecules; how glucose is stored in the liver and muscles

pancreas

endocrine gland behind the stomach the regulates blood sugar with two hormones

central nervous system

processes and analyzes information from the peripheral nervous system; brain and spinal cord

peripheral nervous system

consists of nerves that conduct signals to and from the central nervous system

stimulus

anything that causes a response

response

a reaction to a stimulus

feedback inhibition

synonym for negative feedback; a change in the body causes the body to reverse the change

insulin

hormone produced by the pancreas that lowers blood sugar

adrenaline

hormone released by the adrenal glands in response to physical or mental stress
