neuron cluster, found deep within the white matter of the cerebrum, that controls motor function/voluntary movement
is located beneath the cerebrum and is part of the brain that processes information coming from motor neurons
fluid that surrounds the central nervous system and fills ventricles of the brain and central canal of the spinal cord; protects the central nervous system
part of the brain that is the site of higher-order thinking, memory, centralization of the information received by the senses, and control of voluntary movements
decussation of the pyramids
where the group of nerve fibers crosses just above the area where the medulla oblongata meets the spinal cord
part of the brain located just below the thalamus that is responsible for regulating metabolism. Most of the information processed by the limbic system goes through the hypothalamus.
structure that is continuous with the spinal cord and controls several involuntary functions such as breathing, swallowing, and heart rate
controls vision, hearing, and motor control. The midbrain also controls sleep cycles, alertness, and regulation of body temperature.
fatty sheath that protects and nourishes some nerve cells and increases speed at which impulses travel
part of the brain stem located between the midbrain and the medulla oblongata that serves as a relay center, transmitting signals from different parts of the nervous system to the brain and back to the effector organs
collection of nerves that spans the entire brain stem and maintains alertness of the cerebrum
structures in the midbrain that have a high melanin pigment concentration needed for the formation of neurotransmitters
one of the parts of the midbrain that contains visual reflex centers that cause the head and the eyes to work in conjunction when looking at an object
large gray mass at the top of the diencephalon responsible for sending sensory and motor signals to the cerebral cortex
