Document Summary
Sends signals to activate muscles on the right of the body. Sensory information from the right side of the body travels to the left hemisphere. Controls basic functions of the body like heart rate and respiration. Made up of the midbrain, pons, and medulla oblongata. Gyri (bumps) and sulci (dips) on the surface of the brain. These folds are most prominent in humans and increase the surface area of the brain. The locations of the sulci and gyri are quite consistent between individuals (minor differences in size and shape) and are so prominent they have specific names. Primary motor cortex: processes input from skeletal muscles throughout the body. Motor association area (premotor cortex) and the prefrontal cortex integrate movement information with other sensory inputs to generate perception (interpretation) of stimuli. Primary somatosensory cortex: receives input from the major sense organs (skin, musculoskeletal system, and taste buds) Association areas of the parietal lobe integrate sensory information with.
