The temporal lobe: The part of the cerebrum that plays a role in terms of memory and hearing, among other things.

The frontal lobe: The part of the cerebrum that enables some of the senses, thinking, movement, judgement and a person's ability to write words, among other things.

Cerebrum: The largest part of the brain that coordinates and enables bodily movement, sensory perception, learning, the sense of smell, the senses, memory, thinking, judgement and language and communication abilities.

White matter: The substance in the central nervous system that plays a lesser role in the central nervous system's functioning than the gray and the substance that contains far fewer cells than the gray matter.

Gray matter: The gray colored substance in the central nervous system that plays a higher role in the central nervous system's functioning than the white matter and the substance that contains myelinated neurons, unmyelinated neurons, glial cells, and circulatory capillaries.

Brain: The major organ of the body that controls and manages virtually all physiological and emotion bodily responses.

Dura mater: The outermost layer of the meninges.

Arachnoid: The middle layer of the meninges.

Pia mater: The innermost layer of the meninges.

Meninges: The protective membrane that covers the brain and the spinal cord.

Central nervous system: The part of the nervous system that consists of the brain and the spinal cord.

Somatic nervous system: Controls voluntary physiological bodily functions such as voluntary muscular movements with the skeletal muscles of the body.

Autonomic nervous system: Controls automatic and involuntary physiological functions of the body that are outside of our voluntary control.

Afferent nerves: Nerves that send and receive sensory function related nerve signals.

Efferent nerves: Nerves that send and receive motor function related nerve signals.

The senses: Hearing, vision, smelling, tasting and touch.

Motor neurons or nerves: The neurons that send and transmit message that involve muscle movement.

Sensory neurons or nerves: The neurons that 'sense' and transmit information from the external environment.Synapse: The point at which neurons gently touch each other to send or receive a nerve impulse or message.Glial cells: A type of nervous system cell, other than a neuron, that forms myelin which is the covering or sheath over parts of the neuron.Neurons: The primary nervous system cells.Glossary of Nervous System Terms and Terminology
