Document Summary
Cns with all internal organs, controlled by he sympathetic and parasympathetic nervous systems: responsible for fast-acting, short duration responses to changes in the body. A erent vs e erent: a erent (sensory) impulses from peripheral nerve endings > brain > e erent (motor) impulses to extremities and internal organs. Hindbrain: made up of three parts (medulla, pons, and cerebellum) Pons: link between the hindbrain and the medulla. Cerebellum: coordinates voluntary muscle movement, balance and equilibrium, muscle tone and posture. Midbrain: major pathway for sensory and motor impulses moving between the forebrain and the hindbrain, also responsible for the coordination of visual and auditory re exes. Forebrain: diencephalon (thalamus and hypothalamus) and telencephalonon (is composed of the left and right hemispheres of the cerebral cortex) Thalamus: recognition of sensory stimuli and relay of sensory impulses to the cerebral cortex. Hypothalamus: helps regulate the centres in the medulla that control cardiac functioning, blood pressure, and respiration.
