Question

Mukesh was looking for a slide of a nerve cells among five unlabelled slides. Which of the following will help him identify the nerve cells?

a) Spindle shaped cells with big central nucleus

b) Red coloured, biconcave disc shaped enucleated cells

c) A cell body with branched extensions at one end and a long projection at the other

d) Round or oval cells with a bilobed nucleus

Answer 1

Spindle shaped cells with big central nucleus is a non striated muscle so this is ruled out
b) Red coloured, biconcave disc shaped enucleated cells are RBCs so this is ruled out

c) A cell body with branched extensions at one end and a long projection at the other is a nerve cell

d) Round or oval cells with a bilobed nucleus is Eosinophil, so this is also ruled out

So the right answer is C. Because a nerve cell is observed having a cell body, branched cytoplasmic extensions (dendrites) and a long extended fibre –the axon.
