Cerebellum
The second largest part of brain, coordinates body movement and maintains balance.
What does -cele refer to in neurology?
In neurology, -cele refers to a birth defect in which portion of nervous system protrudes through opening in vertebral column.
Cerebrum
Largest part of the brain; receives sensory information and sends motor commands; also responsible for memory, problem solving, and language; divided into frontal, parietal, temporal and occipital lobes.
Brain
The brain is one of the largest organs in the body; coordinates most body activities; right side of brain controls left side of body and left side brain controls right side of body.
What are the subdivisions of the brain?
Four sections of brain are cerebrum, cerebullum, thalamus, and brain stem; each section performs specific duties.
Medulla Oblongata
Part of the brain stem; connects rest of brain to spinal cord; contains control centers for respiration, heart rate, temperature, and blood pressure.
Meninges
A three-layer protective sac around brain and spinal cord, outer layer is dura mater, middle layer is arachnoid layer, and inner layer is pia mater.
Spinal Cord
A column of nervous tissue providing path for messages traveling to and from brain.
Nerve
A cordlike bundle of neurons carrying messages between the CNS and muscles and organs of body; sensory nerves carry information to CNS; motors nerves carry messages from CNS to muscles and organs.
Pons
Another part of the brain stem; connects cerebellum to rest of brain.
Thalamus
Part of the brain that relays incoming sensory information to correct part of cerebrum.
