Sample Questions

Q1.During repolarisation of the axonal membrane:

  • ANa+ rushes into the cell
  • BK+ diffuses outside the membrane, restoring the resting potential
  • CThe membrane becomes more permeable to Na+
  • DNeurotransmitters are released

Q2.The neural system of all animals is composed of highly specialised cells called:

  • ANephrons
  • BNeurons
  • CHepatocytes
  • DMyocytes

Q3.If efferent nerve fibres to a muscle are damaged, what would be the expected result?

  • AThe person cannot feel pain in that muscle
  • BThe person cannot voluntarily move that muscle
  • CThe person feels increased sensation
  • DThe muscle becomes stronger

Q4.In a reflex arc where a person touches a hot object, which is the correct pathway of nerve impulse?

  • AEfferent neuron to CNS to afferent neuron to effector
  • BReceptor to afferent neuron to CNS to efferent neuron to effector (muscle)
  • CCNS to receptor to efferent neuron to muscle
  • DEffector to afferent neuron to receptor

Q5.The cerebral cortex is referred to as grey matter because:

  • AIt is covered with myelin sheaths
  • BNeuron cell bodies are concentrated here, giving a greyish appearance
  • CIt contains white fibres
  • DIt is made of connective tissue
