Ch 14 Nervous System
Anatomy and Physiology
Question | Answer |
---|---|
nerves that carry sensory nerve impulses from the body to the brain (or from the body to the spinal cord) | afferent nerves (sensory) |
division of the peripheral nervous system that carries nerve impulses to the heart, involuntary smooth muscle, and glands. It includes the parasympathetic division and the sympathetic division | autonomic nervous system |
division of the nervous system that includes the brain and the spinal cord | central nervous system |
nerves that carry motor nerve impulses from the brain to the body (or from the spinal cord to the body) | efferent nerves (motor) |
body system that consist of the brain, spinal cord, cranial nerves, and spinal nerves. It receives nerve impulses from the body and sends nerve impulses to the body. It includes the central nervous system and the peripheral nervous system. | nervous system |
division of the ANS. It includes the neurotransmitter acetylcholine. It directs the activity of the heart, involuntary smooth muscles, and glands while body is at rest (rest and digest) | parasympathetic nervous system |
division of the NS that includes the cranial nerves and spinal nerves | peripheral nervous system |
structure on the cell membrane of a dendrite (or on a muscle, organ or gland) where a neurotransmitter binds | receptor |
involuntary muscle reaction that is controlled in the spinal cord. In response to a sudden pain or muscle stretch, the spinal cord immediately sends a command to move. The entire circuit that the nerve travels through is known as reflex arc | reflex |
division of the peripheral nervous system that controls the movements of voluntary skeletal muscles | somatic nervous system |
division of the ANS. It uses neurotransmitter norepinephrine. It directs the activity of the heart , inv. muscles, and glands during times of increased activity. During danger and stress (flight, fight), releases epinephrine into blood | sympathetic division |
