Nervous System Two parts of nervous system: 1. 2. Central (brain and spinal cord) Peripheral (somatic and autonomic nerves) Functions: Coordination of the physical movement of the body as well as responding to the action of all the senses of hearing, sight, smell, taste, and touch Enables animals to react to the internal and external stimuli in their environment Neurons: Nerve Cells Axon: Single, long fiber in neurons Dendrites: Several, branched threads in neurons Synapse: Point axon at which the dentrite connects to the Nerve Trunks: Bundles of neurons Gangloins: Nerve bundles which occur outside of the brain or spinal cord Sensory or Afferent Neurons: Nerve cells that receive stimuli and carry them to the central nervous systems Parts of the Brain Cerebrum Largest part of the brain Responsible for decision-making or thinking process that controls voluntary muscle activity and reacts to stimuli of the senses Damage will not cause all body functions to stop Cerebellum: Coordinator of the message from other parts of the brain to the body Damage will not cause paralysis Pons and Medulla Oblangota: Controls reflex actions such as blinking, vomiting, breathing, and swallowing Spinal Cord: Main avenue from message transferal between the brain and other parts of the body Motor Nerve Fibers: Transmit the responses from the brain back to the body Somatic Nerves: Include all nerve structures located outside of the brain and spinal cord which control the functions of body tissue other than organs (parts of the peripheral nervous system) Autonomic Nerves: Located outside the central nervous system Relatively independent Controls the functions of involuntary muscles in internal organs (heart and stomach) Transmit messages between the brain and involuntary muscles (part of the peripheral nervous system)
