The neural system of all animals that consists of specialized cells called neurons.

Controls all the activities of the body, including voluntary movements, involuntary functions, and processing information.

The main part of the central nervous system (CNS), responsible for processing information, controlling movements, and higher-level functions.

The network of nerves branching out from the central nervous system (CNS), connecting it to the rest of the body.

Nerve fibers that carry sensory information from the body to the central nervous system (CNS).

Nerve fibers that carry motor commands from the central nervous system (CNS) to the body.

The part of the peripheral nervous system (PNS) that controls voluntary movements of skeletal muscles.

The part of the peripheral nervous system (PNS) that controls involuntary functions like heart rate, digestion, and breathing.

The part of the autonomic nervous system (ANS) that prepares the body for 'fight-or-flight' responses, like increased heart rate and breathing.

The part of the autonomic nervous system (ANS) that helps to conserve energy and promote 'rest and digest' functions.

The functional unit of the nervous system, responsible for transmitting nerve impulses.

The central part of a neuron, containing the nucleus and other cell organelles.

Short, branched extensions of a neuron that receive signals from other neurons.

A long, slender extension of a neuron that transmits signals to other neurons or muscles.

The difference in electrical charge between the inside and outside of a neuron's membrane when it is at rest.

The rapid change in electrical potential across a neuron's membrane that occurs when a signal is transmitted.

The specialized junction between two neurons where nerve impulses are transmitted.

Chemical messengers released by neurons at synapses to transmit signals to other neurons or muscles.

The largest part of the brain, responsible for higher-level functions such as thought, memory, and language.

A structure in the forebrain that relays sensory information to the cerebrum.

A structure in the forebrain that controls basic survival functions like hunger, thirst, and body temperature.

A part of the forebrain involved in emotions, memory, and motivation.

The part of the brain located between the forebrain and the hindbrain, involved in processing sensory information and controlling movement.

The part of the brain located at the back of the head, responsible for coordination, balance, and motor control.

The lowest part of the brain, connecting to the spinal cord, responsible for controlling vital functions like breathing and heart rate.

The process by which an electrical signal travels along a neuron's axon.

The process by which a nerve impulse is transmitted from one neuron to another across a synapse.

A type of synapse where electrical signals are transmitted directly between neurons.

A type of synapse where chemical messengers (neurotransmitters) are released to transmit signals between neurons.

When a stimulus reaches the threshold, causing the opening of sodium channels and an influx of positively charged sodium ions into the neuron.

When the inside of a neuron becomes more negative again after depolarization, due to the potassium ions leaving the cell.

A protective sheath that wraps around some axons, increasing the speed of signal transmission.

The spaces between sections of myelin sheath on an axon, where the signal is amplified.
