Nervous System: a physically connected network of cells, tissues, and organs that controls thoughts, movements, and dimplier life processes such as swallowing.
Endocrine System: a collection of physically disconnected organs that helps to control growth, development, and responses to your environment, such as body temperature.
Stimulus: something that causes a response.
Central Nervous System : includes the brain and spinal cord. Interprets messages from other nerves in the body and stores some of these messages for later use.
Peripheral Nervous System : a network of nerves that transmits messages to the CNS and from the CNS to other organs in the body.
Neuron: a specialized cell that stores information and carries messages within the nervous system and between other body systems.
Dendrites: branchlike extensions of cytoplasm and the cell membrane that receive messages from the neighboring cells.
Axon: a long extension that carries electrical messages away from the cell body and passes them to other cells.
Resting Potential: the distance in charge across the membrane.
Sodium Potassium Pump: protein that uses energy to actively transport Na+ ions out of the cell and bring K+ ions into the cell.
Action Potential: charge distribution that triggers a moving electrical impulse.
Synapse: a tiny gap between the neurons.
Terminal: the part of the axon through which the impulse leaves the neuron.
Neurotransmitters: chemical signals of the nervous system.
Rod Cells: detect light intensity and are used in black and white vision.
Cone Cells: Detects color.
Hair Cells: specialized cells in the inner ear that contain mechanoreceptors that detect vibrations.
Cerebrum: the part of the brain that interprets signals from your body and forms responses such as hunger, thirst, emotions, motion, and pain.
Cerebral Cortex: interprets information from your sensory organs and generates responses.
Cerebellum: part of the brain that coordinates movements. Helps maintain posture, balance and automatically adjusts your body to help you move smoothly.
Brain Stem: connects the brain to the spinal cord and controls the most basic activities required for survival.
Reflex Arcs: nerve pathways that need to cross only two synapses before producing a response.
Somatic Nervous System: the division of the PSN that regulates all of the movements over which you have voluntary control.
Autonomic Nervous System: the division of the PNS that controls automatic functions that you do not have to think about.
Sympathetic Nervous System: the part of the autonomic nervous system that prepares the body for action and stress.
Parasympathetic Nervous System: the division of the autonomic nervous system that calms the body to conserve energy.
Addiction: the physiological need for a substance.
Desensitization: when there is more neurotransmitter present in the synapse than usual.
Tolerance: Takes a larger dose of the drug to produce the same effect.
Sensitization: Occurs when low amounts of a neurotransmitter are in the synapses.
Stimulants: drugs that increase the number of action potentials that neurons generate by the drugs that increase the number of action potentials that neurons generate by increasing the amounts of neurotransmitter in the synapse.
Depressants: drugs that make a person feel relaxed and tired.
Hormones: chemical signals made by the endocrine system.
Glands: create and release hormones into the bloodstream.
Hypothalamus: a small area of the middle of the brain. Makes hormones that stimulate the pituitary gland to release hormones, and stimulates the production of hormones that control growth, reproduction, and body temperature.
Pituitary Gland: another small area of the middle of the brain. Makes and releases hormones that control cell growth as well as osmoregulatory hormones that regulate the concentration of water in the blood.
Releasing Hormones: hormones that stimulate other glands to release their hormones.
