Document Summary

Association area- receiving input from sensory areas and other lower parts of the brain that controls cognitive abilities. Human nervous system is divided into two parts: -central nervous system (cns) Peripheral nervous system (pns) -transmits signals between the brain and the rest of the body. Somatic nervous system-consists of nerves that receive sensory input from the body and control skeletal muscles, which are responsible for voluntary and reflexive movement. Automatic nervous system-receives information from and sends commands to the heart and other organs. Responsible for regulating the activity of organs and glands. Homeostasis-tendency of an animal to regulate its internal conditions by a system of feedback controls to optimize health and functioning, and return to nonemergency state. Central nervous system (cns) - brain and spinal cord. Midbrain-includes neurons that contain very dense concentrations of dopamine receptors and activity. Neurons send messages to higher brain centers involved in the control of movement. Parkinson"s disease caused by loss of dopamine-producing cells.
