The study of the structure of the nervous system.

The nervous system is divided into central and peripheral components.

Comprises the brain and spinal cord.

Includes all nervous system parts outside the CNS.

Part of PNS that controls voluntary muscle movements.

Regulates involuntary body functions, such as heartbeat and digestion.

A division of the autonomic system that prepares the body for stressful situations.

A division of the autonomic system that calms the body and conserves energy.

The human brain is divided into five main parts: forebrain, midbrain, hindbrain, diencephalon, and brainstem.

The forebrain includes the cerebrum, thalamus, and hypothalamus; it's responsible for complex functions like thought and emotion.

Also known as the mesencephalon, the midbrain acts as a relay station for visual and auditory information.

The hindbrain comprises the medulla, pons, and cerebellum, regulating basic life functions and motor control.

A clear fluid surrounding the brain and spinal cord, providing cushioning, nutrients, and waste removal.

Part of the nervous system regulating involuntary actions like heartbeat and digestion.

Nerves that carry motor signals from the CNS to muscles or organs.

Nerves that carry sensory signals to the CNS from the body.

The part of the nervous system outside the brain and spinal cord.

Nerves that mobilize energy in threatening situations.

Nerves that conserve energy and promote 'rest and digest'.

A cluster of cell bodies in the CNS.

A cluster of cell bodies in the PNS.

A bundle of axons in the CNS.

A bundle of axons in the PNS.

Contains cell bodies and unmyelinated axons.

Composed of myelinated axons; facilitates communication.

The outer layer of the brain involved in sensory processing, motor control, and higher cognitive functions.

A brain structure involved in movement coordination and timing.

A two-lobed structure that relays sensory information to the cerebral cortex.

Regulates essential behaviors like feeding, sleeping, and temperature control.

A group of nuclei that coordinate movement and are essential for learning.

A group of structures involved in emotions and memory.

A part of the limbic system involved in forming new memories and spatial navigation.

An almond-shaped structure involved in processing emotions and fear responses.

Network of neurons that regulates wakefulness, arousal, and alertness.

Also known as the midbrain, it processes visual and auditory information.

A condition resulting from a stroke affecting the medulla, causing paralysis and respiratory failure.

A neurological disorder where brain tissue protrudes into the spinal canal, causing various symptoms.

Feedback loops between the thalamus and cortex critical for consciousness and sensory integration.

A part of the midbrain that plays a role in visual and auditory reflexes.
