Q1: Define reflex action. Draw a labeled diagram of a reflex arc and explain how it works.

Reflex action is a quick, involuntary response to a stimulus that does not involve the brain. It happens automatically without conscious thought. Reflex arc components (in order of response): 1. Receptor (e.g., sensory nerve ending in skin) - detects stimulus 2. Sensory neuron (afferent neuron) - c...

Q2: What is the structure and function of a neuron? How do neurons transmit signals?

Structure of a neuron (nerve cell): 1. Dendrites - short branching extensions that receive signals from other neurons 2. Cell body (soma) - contains nucleus; integrates signals 3. Axon - long extension that transmits signals away from cell body 4. Axon terminals - branches at end of axon that form s...

Q3: Compare the nervous system and endocrine system. How do they coordinate body functions?

Nervous system: - Uses electrical signals (action potentials) - Transmission through neurons - Very fast (milliseconds) - Effects are localized and short-term - Composed of brain, spinal cord, and nerves - Divisions: Central nervous system (brain and spinal cord) and Peripheral nervous system (somat...
