Nervous+System

The CNS and PNS [Nowicki,875] [Vinnie] Peripheral Nervous System [Nowicki, 875] [Vinnie] The dendrites [Nowicki, 876] [Vinnie] Somatic Nervous System: Transport signals from the brain to the muscles that produce voluntary movements. [Nowicki,R70] [Vinnie] Autonomic Nervous System: Controls automatic without thinking. [Nowicki,890] [Vinnie]
 * What is homeostasis?** Regulation that maintenance of the internal environment. [Nowicki, R56] [Vinnie]
 * How does the nervous system help the body maintain homeostasis?** It tells systems in the body when an adjustment is needed. It sends messages that control all the systems of the body. [ Nowicki, 874] [Vinnie]
 * How are the two parts of the nervous system different?** The CNS interprets messages and stores for later use. The PNS is a network that transmits messages to the CNS. [Nowicki,875] [Vinnie]
 * What are the major structures of the nervous system?**
 * What is a stimulus?** Something that causes a response.[Nowicki,874] [Vinnie]
 * What are neurons?** Carries messages within the nervous system and between other body systems.[Nowicki,876] [Vinnie]
 * What part of the neuron receives signals?** The dendrites [Nowicki, 876] [Vinnie]
 * To what part of the nervous system do motor neurons and sensory neurons belong?**
 * What is the electrical impulse that moves down an axon called?**
 * What are the chemical signals that allow one neuron to stimulate another?** The resting potential, because it contains the potential energy needed to transmit an impulse. [Nowicki,877] [Vinnie]
 * When and where is an impulse an electrical signal?** Neurons transmit information in the form of electrical and chemical impulses. Neurons is stimulated, it produces an electrical impulse that travels only within that neuron. Before the signal can move to the next cell, it changes into a chemical signal. [Nowicki,877] [Vinnie]
 * From sensing a stimulus to producing a response, how do your CNS and PNS work together?** PNS transmits message to the CNS and from the CNS to other organs in the body. The CNS stores the messages for later on use.[Nowicki,875] [Vinnie]
 * How is a reflex arc different from other responses?** The signal never travel up the spinal cord to the brain, you react quickly. [Nowicki,889] [Vinnie]
 * What is the difference between the two parts of the PNS?**

__29.1__
 * Stimulus:** Is anything that triggers a change in an organism. Example: behavior. [Vinnie]
 * nervous system:** is a physically connected network, that controls thoughts, movements, and simpler life processes such as swallowing. [Vinnie]
 * central nervous system (CNS):** includes the brain and spinal cord. [Vinnie]
 * peripheral nervous system (PNS):** network of nerves that transmits message to the CNS and from the CNS to another organs in the body. [Vinnie]
 * endocrine system:** Collection of physically disconnected organs that helps to control growth, development, and responses to your environment, such as body temperature. [Vinnie]

__29.2__
 * Neuron:** Specialized cell that stores information and carries messages within the nervous system and between other body systems. [Vinnie]
 * Dendrite:** branchlike extensions of the cytoplasm and the cell membrane that receive message. [Vinnie]
 * Axon:** long extension that carries electrical messages. [Vinnie]
 * action potential:** that triggers a moving electrical impulse. [Vinnie]
 * Terminal:** part of axon, vesicles bind to the terminal’s membrane and release their chemicals into synapse. [Vinnie]
 * Neurotransmitter:** Chemicals into the synapse. [Vinnie]
 * Synapse:**

__29.4__
 * Cerebrum:** part of the brain responses to hunger, thirst, emotions, motion, and pain. [Vinnie]
 * Cerebellum:** part of the brain that coordinates your movements. [Vinnie]
 * reflex arc:** spinal cord also controls involuntary movements. [Vinnie]
 * somatic nervous system:** the PNS that regulates all of the movements over which you have voluntary control. [Vinnie]
 * autonomic nervous system:** control automatic functions that you don’t have to think about. [Vinnie]
 * __29.6__**
 * Glands:** which can be found in many different areas of the body. [Vinnie]
 * Hormones:** chemical signals made by the endocrine system. [Vinnie]
 * Hypothalamus:** small area of the middle of the brain. [Vinnie]
 * releasing hormone:** stimulate other glands to release their hormones. [Vinnie]
 * pituitary gland:** in the middle of the brain. [Vinnie]
