Across
- 3. is a muscle or gland that responds to the commands from the nervous system.
- 6. is the junction between two neurons where the transmission of nerve impulses occurs through chemical messengers called neurotransmitters.
- 8. is an automatic, quick, and involuntary response to a stimulus that does not involve conscious thought.
- 9. is the structural and functional unit of the nervous system which transmits information in the form of electrical impulses.
Down
- 1. is any change in the environment to which an organism responds.
- 2. is the pathway followed by nerve impulses during a reflex action.includes the receptor → sensory neuron → spinal cord → motor neuron → effector.
- 4. are specialized cells or tissues in our body that detect stimuli and send information to the brain or spinal cord through sensory neurons.
- 5. are short, branched extensions of the neuron that receive nerve impulses from other neurons or receptors and transmit them toward the cell body.
- 7. is a long, cylindrical projection of the neuron that carries nerve impulses away from the cell body to the next neuron, muscle, or gland.
