Regulation Notes Review
| Question | Answer |
|---|---|
| What is the life function by which organisms controls and coordinates its other life functions to maintain existence? | Regulation |
| What is the purpose of the Neuron? | it is the basic functional unit of the the human nervous system |
| Which part of the neuron are fibers that serve to detect a stimulus and direct an impulse toward the cell body? | Dendrites |
| Axon | What is the elongated portion of the neuron that carries the nerve impulses from the cyton toward the terminal branches? |
| Terminal branches | What are the fibers of the neuron leading from the axon on the nerve cell that reach toward the dendrites of the adjacent neurons and secrete chemical neurotransmitters? |
| What is the gap that occurs between adjacent neurons? | synapse |
| What are special chemicals produced and secreted by the neuron's terminal branches? | neurostransmitters |
| What type of neuron receives stimuli from the environment and transmits to central nervous system for interpretation? | Sensory Neurons |
| Which type of neuron is located in central nervous system and interprets sensory impulses and transmits "commands" to motor neurons? | Interneurons |
| What type of neuron carries impulses from the "command centers" in the CNS to effector organs (muscles or glands) when a response is initiated? | Motor Neurons |
| What are bundles of neurons(may contain single type of neuron or two separate types)? | nerves |
| What is the system that contains the brain and spinal cord? | Central Nervous System |
| What is the large organ composed of a mass of interneurons located in the cranial cavity? | the brain |
| What are the three regions the brain is divided into? | cerebrum, cerebellum, medulla |
| What is the largest portion of the brain that regulates conscious thought, memory, sense interpretation, reasoning, and other voluntary activities? | cerebrum |
| What is the part of the brain that is located at the rear of the cranium, and responsible for coordinating muscular activities and balance? | cerebellum |
| Which part of the brain regulates the automatic rhythmic processes of the body? | medulla |
| What starts with a stimulus, and moves from the sensory neuron, to interneuron, to motor neuron, and then to the effector | Reflex arc |
| Which type of neuron receives the stimulus? | sensory neuron, found in the senses |
| Which type of neuron interprets the sensory neurons impulse? | interneuron, found in the spinal cord |
| Which type of neuron carries the impulse from the spinal cord to the muscle? | motor neuron |
| Which system regulates automatic functions? | Autonomic Nervous System |
| Which system controls the nerves of the voluntary skeletal muscles? | Somatic Nervous System |
| Which nerves come off of the CNS? | Peripheral Nervous System |
| Name the congenital disease that effects the muscles and speech. | Cerebral Palsy |
| Name the disease that has inflammation of the meninges. | Meningitis |
| Name the disease where there is a chronic breakdown of the neurons in the brain. | Alzheimer's disease |
| What is it called if brain function is impaired from the lack of oxygen? | Stroke |
