Which gland plays major role in the differentiation of T-lymphocyte?Options :AThymusBThyroidCGonadsDAdrenal

Break Down the Problem

1. Understanding the Question: We need to identify which gland is primarily responsible for the differentiation of T-lymphocytes.
2. Evaluating the Options: We will consider the function of each gland listed in the options.

Relevant Concepts

1. Thymus Gland: Essential for the maturation of T-lymphocytes from precursor cells.
2. Thyroid Gland: Primarily regulates metabolism and does not play a direct role in T-lymphocyte differentiation.
3. Gonads (testes and ovaries): Primarily involved in the production of sex hormones and gametes, not in T-lymphocyte differentiation.
4. Adrenal Gland: Produces hormones related to stress response, not directly involved in T-lymphocyte differentiation.

Analysis and Detail

• Among the options provided, the thymus is known for its critical role in the immune system, specifically in the development and differentiation of T-lymphocytes.
• T-lymphocytes (or T-cells) start as precursor cells in the bone marrow and migrate to the thymus, where they undergo maturation and selection processes to become functional immune cells.

Verify and Summarize

• After reviewing the functions of each gland, it is clear that the thymus gland is specifically designed for the differentiation and maturation of T-lymphocytes, while the other glands mentioned do not fulfill this role.

Final Answer

A. Thymus
