14138481638 | What makes sensory input possible? | sensors receptor cells and sensory neurons | 24 | |
14138481639 | What is integration? | the brain's job of processing sensory input to make decisions different regions have different functions | 25 | |
14138481640 | What makes integration possible? | communication between interneurons in the brain | 26 | |
14138481641 | What is motor output (voluntary response)? | skeletal muscle is contracted to move skeleton | 27 | |
14138481642 | What is motor output (involuntary response)? | smooth or cardiac muscle is contracted glands are stimulated | 28 | |
14138481643 | What makes motor output possible? | motor neurons and effector tissues (muscles and glands) | 29 | |
14138481644 | In certain cases is there a lack of motor output? | yes communication between interneurons in the brain can create its own end result | 30 | |
14138481645 | Why are nutrients important? | they play specific roles in maintaining homeostasis and cellular metabolism in the body | 31 | |
14138481646 | What is the major organ of the digestive system? | the gastrointestinal (GI) tract, which includes the mouth, pharynx, esophagus, stomach and intestines | 32 | |
