Propolis Cognitive Error Autopsy

Official Correct Choice:
Option D: T-lymphocytes
Concept:

Lymphocytes are named based on the primary lymphoid organ where they undergo their final maturation and selection.

Formula:

None

Solution:

  • All blood cells originate from hematopoietic stem cells in the bone marrow.


  • A specific lineage of immature lymphocytes leaves the marrow and migrates to the thymus gland situated in the upper chest.


  • Within the thymus, under the influence of thymosin hormones, these cells mature into immunocompetent T-lymphocytes (the 'T' literally stands for Thymus).


Why other options are incorrect:

  • B-lymphocytes: Mature entirely within the Bone marrow.
