Question

Rearrange the following in the correct sequence pertaining to what is given within brackets at the end.
(a) Effector Sensory neuron Receptor Motor neuron Stimulus Central nervous system Response (Reflex arc)
(b) Repolarisation Depolarisation Resting (polarised) (during conduction of nerve impulse through a nerve fibre)
(c) Axon endings Nucleus Dendrites Axon Perikaryon Dendron (Neuron structure)
(d) Diencephalon Cerebellum Medulla oblongata Pons Cerebrum mid brain (sequence of parts of human brain).

Answer 1

The rearranged correct sequences are as follows

(a) Stimulus – Receptor – Sensory neuron – Central nervous system – Motor neuron – Effector – Response
(b) Resting – Depolarization – Repolarization
(c) Dendrites – Dendron – Perikaryon – Nucleus – Axon – Axon endings
(d) Cerebrum – Diencephalon – Mid-brain – Cerebellum – Pons – Medulla oblongata
