Nervous system divisions

The part of the nervous system consisting of the brain and spinal cord receives sensory input and organizes, analyzes, and processes neural information.

Central nervous system

The uppermost and largest part of the brain, consisting of a left and right hemisphere, responsible for receiving and processing sensory information and controlling the body.

Cerebrum

the region of the brain responsible for conscious motor coordination.

Cerebellum

the trunk of the brain, consisting of the medulla oblongata, pons, and midbrain, that continues downward to form the spinal cord.

Brain stem

the part of the brain where most neural integration occurs.

Cerebral cortex

the brain region responsible for motor movement and processing auditory and visual information.

Midbrain

the brain region responsible for posture, facial movement, and sleep.

Pons

the base of the brain stem, responsible for involuntary functions such as swallowing, sneezing, and heart function.

 Medulla oblongata

the brain region responsible for relaying sensory and motor signals and regulating consciousness.

Thalamus

the neural tissue extending from the medulla oblongata to the lumbar region (lower back) of the vertebral column that connects the body and the brain.

Spinal cord
