Across
- 3. neurons within the brain and spinal cord; they communicate internally and process information between the sensory inputs and the motor outputs
- 5. neurons that carry outgoing information from the brain and spinal cord to the muscles and glands
- 10. the body's speedy, electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems
- 11. bundled axons that form neural cables connecting the central nervous system with muscles, glands, and sense organs
- 13. the division of the peripheral nervous system that controls the body's skeletal muscles. Also called the skeletal nervous system
- 15. the endocrine system's most influential gland. Under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glands
- 16. the sensory and motor neurons that connect the central nervous system to the rest of the body
Down
- 1. chemical messengers that are manufactured by the endocrine glands, travel through the bloodstream, and affect other tissues
- 2. neurons that carry incoming information from the body's tissues and sensory receptors to the brain and spinal cord
- 4. the part of 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
- 6. the body's "slow" chemical communication system; a set of glands that secrete hormones into the bloodstream
- 7. the division of the autonomic nervous system that arouses the body, mobilizing its energy
- 8. the division of the autonomic nervous system that calms the body, conserving its energy
- 9. the brain and spinal cord
- 12. a pair of endocrine glands that sit just above the kidneys and secrete hormones (epinephrine and norepinephrine) that help arouse the body in times of stress
- 14. a simple, automatic response to a sensory stimulus, such as the knee-jerk response
