The concept that the mind exists separately from the body.

The belief that psychological experiences are tied to physical processes.

The body’s electrochemical communication system that influences behavior.

Includes the brain and spinal cord, controlling the body.

All nerve cells outside the CNS, including sensory and motor neurons.

Part of the PNS that manages voluntary movements.

Part of the PNS that regulates involuntary functions like heartbeat.

Sympathetic prepares for stress; Parasympathetic calms and conserves energy.

Cells that communicate within the nervous system, organizing experiences.

Carry incoming information from sense receptors to the central nervous system (CNS).

Carry outgoing information from the CNS to muscles and glands.

Connect sensory and motor neurons, facilitating communication.

Supportive cells that nourish, protect, and maintain neurons.

A substance that insulates neuronal axons, speeding up signal transmission.

An electrical impulse that travels along the axon of a neuron, signaling activity.

Chemicals released by neurons to communicate with each other and influence functions.

A long fiber of a neuron that transmits nerve impulses away from the cell body.

Branch-like structures on neurons that receive signals from other neurons.

A fatty layer that insulates axons, speeding up nerve signal transmission.

The end point of an axon where neurotransmitters are released.

The gap between neurons where neurotransmitters are released.

The principle that a neuron either fires completely or not at all.
