Presentation transcript:

The Nervous System Somatic Nervous System- The division of the peripheral nervous system that connects the central nervous system with sensory receptors, muscles, and the skin. Autonomic Nervous System- The subdivision of the peripheral nervous system that regulates body functions, such as respiration and digestion.

Parts of the Human

Parts of the Human Brain Forebrain Reticular activating system (upper part)- The part of the brain that is involved in attention, sleep, and arousal. Thalamus- The structure of the brain that relays messages from the sense organs to the cerebral cortex. Hypothalamus- The neural structure located below the thalamus that control temperature, hunger, thirst, and various aspects of emotion. Cerebrum- The large mass of the forebrain, consisting of two hemispheres. Cerebral cortex- The bumpy, convoluted surface of the brain; the body’s control and information processing center. Corpus callosum- The nerve fibers that connect the left and right hemispheres of the cerebral cortex.

Parts of the Human Brain Midbrain Reticular activating system (middle part) Hindbrain Reticular activating system (lower part) Medulla- A structure at the base of the brain stem that controls vital functions such as heartbeat and breathing. Cerebellum- The area of the brain that is responsible for voluntary movement and balance. Pons- A brain structure located at the top of the brain stem that is involved in respiration, movement, and sleep.
