The Nervous System
| Question | Answer |
|---|---|
| What are support cells? | Nonexitable cells that provide structural support or that serve important physical and immunological |
| What is the cerebrum? | The large rounded structure of the brain occupying most of the cranial cavity, divided into two cerebral hemispheres that are joined at the bottom by the corpus callosum. |
| What does the cerebrum control? | It controls and integrates motor, sensory, and higher mental functions, such as thought, reason, emotion, and memory. |
| What is the cerebellum responsible for? | It is responsible for the regulation and coordination of complex voluntary muscular movement as well as the maintenance of posture and balance. |
| What is the nervous sytem? | The system of cells, tissues, and organs that regulates the body's responses to internal and external stimuli. In vertebrates it consists of the brain, spinal cord, nerves, ganglia, and parts of the receptor and effector organs. |
| What is the cerebral cortex? | The extensive outer layer of gray matter of the cerebral hemispheres, largely responsible for higher brain functions, including sensation, voluntary muscle movement, thought, reasoning, and memory. |
| What is the hypothlamus? | The part of the brain that lies below the thalamus, forming the major portion of the ventral region of the diencephalon and functioning to regulate bodily temperature, certain metabolic processes, and other autonomic activities. |
| What is the synapse is it and where located? | The junction across which a nerve impulse passes from an axon terminal to a neuron, muscle cell, or gland cell. |
| What is the autonomic nervous system? | The part of the vertebrate nervous system that regulates involuntary action, as of the intestines, heart, and glands, and that is divided into the sympathetic nervous system and the parasympathetic nervous system. |
| What is the central nervous system? | The portion of the vertebrate nervous system consisting of the brain and spinal cord |
