Document Summary

Core of the brain = basic physiological functions. Bridge for carrying nerve impulses between higher and lower levels of the nervous system. Not part of the brainstem but is connected. All input to and from the brain motor nerve tracts here passes through. Also plays a role in certain types. Neurons that control muscles in the face and neck. Physical damage = uncoordinated/ jerky movements/ inability to perform habitual movements such as walking. Nger shaped structure that extends from neurons as well as many sensory and motor. Bre tracts that connect higher and lower portions of the nervous system. Impulses from eyes and ears are organized here and sent to the forebrain. Alerts higher centers of the brain that messages are coming, either blocks them or sends them forward. Ascending part- sends input to higher regions of the brain. without stimulation sensory messages do not register in conscious awareness.
