the bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body
central nervous system
brain and spinal cord
a nerve cell; the basic building block of the nervous system.
complex cable of neurons(nerves) that runs down the spine, connecting the brain to most of the rest of the body.
connector of sensory and motor found in the spinal cord
a simple, automatic, inborn response to a sensory stimulus, such as the knee-jerk response
long fiber that carries impulses away from the cell body of a neuron
a jellylike fluid inside the cell in which the organelles are suspended
picks up stimuli from the internal or external environment and converts each stimulus into a nerve impulse
a neuron that sends an impulse to a muscle gland, causing the muscle or gland to react
bundles of axons coated in myelin that travel together through the body
Touch, taste, smell, sight, and hearing.
the act of perceiving the odor of something
The chemical sense which perceives or distinguishes flavor.
the perception of light by the eyes
the sensation produced by pressure receptors in the skin
perceive (sound) via the auditory sense
away from the central part; on the edge
peripheral nervous system
all the nerves located outside the central nervous system; connects the central nervous system to all parts of the body
The part of the central nervous system that is located in the skull and controls most functions in the body
large part of the brain that controls the senses and thinking
the "little brain" attached to the rear of the brainstem; it helps coordinate voluntary movement and balance
part of the brain nearest the spinal cord which controls breathing, heart rate and blood pressure
the junction between the axon tip of the sending neuron and the dendrite or cell body of the receiving neuron
space between the axon terminal of one neuron and the receptors of the next neuron
