Sample questions

1. 1.Match each neuron type with its location: (a) Multipolar - (i) retina of eye; (b) Bipolar - (ii) cerebral cortex; (c) Unipolar - (iii) embryonic stage. Choose the correct matching.
   • A.a-ii, b-i, c-iii
   • B.a-i, b-ii, c-iii
   • C.a-iii, b-i, c-ii
   • D.a-ii, b-iii, c-i
2. 2.How do the thalamus and hypothalamus differ in function?
   • A.The thalamus is a major coordinating centre for sensory and motor signalling, while the hypothalamus controls body temperature and the urge for eating and drinking
   • B.The thalamus controls body temperature while the hypothalamus coordinates sensory and motor signals
   • C.Both lie in the hindbrain and control respiration
   • D.The hypothalamus connects the two cerebral hemispheres while the thalamus secretes hormones
3. 3.Chemicals involved in the transmission of impulses at chemical synapses are called:
   • A.Neurotransmitters
   • B.Hormones
   • C.Enzymes
   • D.Antigens
4. 4.Arrange the events of an action potential at one site in correct sequence: (1) Rise in K+ permeability and efflux of K+ restoring resting potential. (2) Stimulus makes membrane freely permeable to Na+. (3) Rapid influx of Na+ and reversal of polarity (depolarisation).
   • A.2, 3, 1
   • B.3, 2, 1
   • C.1, 2, 3
   • D.2, 1, 3
5. 5.During impulse conduction from site A (depolarised) to the adjacent site B, current flows in which manner to complete the circuit?
   • A.Inner surface from A to B and outer surface from B to A
   • B.Inner surface from B to A and outer surface from A to B
   • C.Only along the outer surface from A to B
   • D.Only along the inner surface from B to A
