Document Summary
Nervous system consists of both the central nervous system (cns) and the peripheral. Cns composed of brain and spinal cord. Muscles and organs considered parts of the pns. Pns can be divided into somatomotor (nerves going to skeletal muscles) and autonomic (going to other organs) nervous systems. 6. 4 & 6. 5 - basic structure of the brain. Left hemisphere sends signals to activate muscles on the right side of the body; similarly, sensory information from right side of body travels to the left hemisphere (vice-versa for right hemisphere) Brainstem controls some of the most basic functions of the body, such as heart rate and respiration. Made up of the midbrain, pons, and medulla oblongata. The medulla is continuous with the spinal cord. At the back, or posterior region, just above the brainstem, is the cerebellum which is responsible for coordinated movement. Diencephalon consists of the thalamus and hypothalamus. Many gyri (bumps) and sulci (dips) on the surface of the brain.
