Question

The lymphoid stem cells in the bone marrow form
(A) Natural killer cells
(B) Platelets
(C) B lymphocytes
(D) Neutrophils
Choose the correct answer from the options given below:

• (A) and (D)
• (A) and (C)
• (A) and (B)
• (C) and (D)

Hint:

Understand the differentiation pathways of lymphoid and myeloid stem cells to identify their respective progeny.

Answer 1

The Correct Option is B

Bone marrow lymphoid stem cells generate two primary immune cell types: natural killer (NK) cells and B lymphocytes. NK cells, part of the innate immune system, offer rapid responses to infected or cancerous cells. B lymphocytes, components of the adaptive immune system, produce antibodies. Platelets and neutrophils, conversely, originate from myeloid stem cells rather than lymphoid stem cells.
