lab brain

cerebral peduncle is a stalk-like structure that connects the cerebrum to the brainstem, playing a crucial role in motor control and coordination.

superior colliculus is a paired structure in the midbrain that integrates sensory information, particularly visual stimuli, and coordinates eye movements.

hypothalamus is a small but crucial brain region located below the thalamus responsible for regulating various autonomic functions, including temperature control, appetite, and sleep cycles.

epidural space is the area between the dura mater and the skull or spinal column that contains fat and blood vessels.

dorsal root is a bundle of nerve fibers that carry sensory information from the body to the spinal cord.

diencephalon is a region of the brain that includes structures such as the thalamus, hypothalamus, and epithalamus, playing key roles in sensory and autonomic functions.

ventral root is a bundle of nerve fibers that carry motor information from the spinal cord to the muscles.

midbrain is the upper part of the brainstem, involved in motor movement, particularly movements of the eye, and in auditory and visual processing.
