B1 Biology - Nervous system
| Question | Answer |
|---|---|
| A change in the environment that your body responds to. | Stimulus |
| This detects a change in the environment | Receptor |
| The 'message' carried along a neurone | Impulse |
| The neurone carrying impulses towards the central nervous system | Sensory neurone |
| The neurone carrying impulses away from the central nervous system | Motor neurone |
| Neurones found inside the central nervous system | Relay neurones |
| Effectors include? | Muscles and glands |
| The brain and the spinal cord make up the.. | Central nervous system |
| Three stimuli that the skin can detect. | Pressure, pain, temperature |
| A junction between neurones | Synapse |
| This carries an impulse across a synpase | Neuro-transmitter |
| A short-cut in the nervous system that avoids the brain | Reflex arc |
| Which part of a neurone does the impulse travel along? | The nerve fibre |
| This prevents impulses leaking away from a neurone | Insulating sheath |
| What are voluntary responses? | Ones controlled by the brain |
| How does a pupil shrink reflex protect the eye? | The pupil constricts to reduce light entering the eye |
