nervous and endocrine system
| Question | Answer |
|---|---|
| the body's speedy, electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems. | nervous system |
| the brain and the spinal cord | central nervous system (CNS) |
| the sensory and motor neurons that connect the central nervous system to the rest of the body | peripheral nervous system (PNS) |
| bundled axons that form neural cables connecting the central nervous system with muscles, glands, and sense organs | nerves |
| neurons that carry incoming information from the brain and spinal cord | sensory (afferent) neurons |
| neurons that carry outgoing information from the brain and spinal cord to the muscles and glands | motor (efferent) neurons |
| neurons within the brain and spinal cord; they communicate internally and process information between the sensory inputs and motor outputs | interneurons |
| the division of the peripheral nervous system that controls the body's skeletal muscles. | somatic nervous system |
| the part if the peripheral nervous system that controls the glands and the muscles of the internal organs (such as the heart). Its sympathetic division arouses; its parasympathetic division calms. | autonomic nervous system |
| the division of the autonomic nervous system that arouses the body, mobilizing its energy | sympathetic nervous system |
| the division of the autonomic nervous system that calms the body, conserving its energy | parasympathetic nervous system |
| a simple, automatic response to a sensory stimulus, such as the knee-jerk response | reflex |
| the body's "slow" chemical communication system; a set of glands that secrete hormones into the bloodstream | endocrine system |
| chemical messengers that are manufactured by the endocrine glands, travel through the bloodstream, and affect other tissues | hormones |
| a pair of endocrine glands that sit just above the kidneys and secrete hormones epinephrine and norepinephrine) that help arouses thee body in times of stress | adrenal glands |
| the endocrine system's most influential gland. Under the influence of the hypothalamus, it regulates growth and controls other endocrine glands | pituitary gland |
