1What is a synapse?
1. AA gap between cells that slows responses down.
2. BA junction between two nerve cells, consisting of a minute gap across which impulses pass by diffusion of a neurotransmitter.
2The receptors are found in [blank_start]sense organs[blank_end]: the [blank_start]eyes[blank_end], the [blank_start]ears[blank_end], the [blank_start]nose[blank_end], the [blank_start]mouth[blank_end] and the [blank_start]skin[blank_end].
1. Asense organs
2. Beyes
3. Cears
4. Dnose
5. Emouth
6. Fskin
3[blank_start]Sensory neurons[blank_end] carry impulses from the receptors to the CNS. [blank_start]Motor neurons[blank_end] carry impulses from the CNS to effector organs, which may be muscles or glands.
1. ASensory neurons
2. BMotor neurons
4The main steps in reflex actions are:
1. A receptor detects a stimulus.
2. A sensory neutron transmits the impulse to the CNS.
3. A relay neutron passes the impulse on.
4. A motor neurone is stimulated.
5. The impulse passes to an effector.
6. Action is taken.
1. ATrue
2. BFalse
5Label this reflex arc.
1. ARelay neuron
2. BSensory neuron
3. CMotor neuron
4. DCNS
