Afferent nerve

• branch of the nervous system that controls involuntary body functions

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

• part of an axon that contains a nucleus

• the brain and spinal cord

Autonomic nervous system

• branch of the nervous system that controls involuntary body functions

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

• part of an axon that contains a nucleus

• the brain and spinal cord

Central Nervous System

• branch of the nervous system that controls involuntary body functions

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

• part of an axon that contains a nucleus

• the brain and spinal cord

Dendrites

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

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

• a long thin fiber connected to the motor neuron cell body

• sheath the fatty bands of insulation surrounding axon

  fibers

Somatic Nervous System

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

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

• branch of the nervous system that stimulates the skeletal muscles

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