A&P Final exam vocab

afferent nerves

• the thin, membranous sheath enveloping a nerve fiber

• sensory transmitters that send impulses from receptors in the skin, muscles, and joints to the central nervous system

• the intersection between a neuron and another neuron, a muscle, a gland, or a sensory receptor

• all parts of the nervous system external to the brain and spinal cord

automatic nervous system

• branch of the nervous system that controls involuntary body functions

• the fatty bands of insulation surrounding axon fibers

• non-neutral tissue that forms the interstitial or supporting elements of the CNS; also known as glial cells

• the thin, membranous sheath enveloping a nerve fiber

cell body

• all parts of the nervous system external to the brain and spinal cord

• branches of a neuron that collect stimuli and transport them to the cell body

• the uninsulated gaps in the myelin sheath of a nerve fiber where the axon is exposed

• part of an axon that contains a nucleus

central nervous system (CNS)

• sensory transmitters that send impulses from receptors in the skin, muscles, and joints to the central nervous system

• the thin, membranous sheath enveloping a nerve fiber

• the brain and spinal cord

• branch of the nervous system that controls involuntary body functions

dendrites

• the uninsulated gaps in the myelin sheath of a nerve fiber where the axon is exposed

• branch of the nervous system that stimulates the skeletal muscles

• branches of a neuron that collect stimuli and transport them to the cell body

• all parts of the nervous system external to the brain and spinal cord

efferent nerves

• motor transmitters that carry impulses from the central nervous system out to the muscles and glands

• sensory transmitters that send impulses from receptors in the skin, muscles, and joints to the central nervous system
