Document Summary
Sits directly above the spinal cord: contains vital life support centers that control autonomic processes such as heart rate, blood pressure, respiration etc, pons of the medulla. Sits above the medulla: transmits information regarding the body"s movement from the cerebral hemisphere to the cerebellum. Structures related to sleep and respiration: midbrain. Lies toward the head end of the pons: controls and coordinates many sensory and motor activities such as the auditory and visual systems, and voluntary movement. Sends signals regarding stressful stimuli upward into the diencephalon and sends signals downward into the brain stem, skeletal muscular system to activate the fof response. Lies above the midbrain, hypothalamus sits below the thalamus: thalamus. Important sensory relay station that gates information from the sense organs to the neocortex. Signal-to-noise ration: thalamus amplifies signals to make them stand out against background noise for signal sensory information to reach conscious awareness, thalamus gate blocks irrelevant sounds.
