GENERAL HISTOLOGY

Detailed explanation-1: -Your thymus is a small gland in the lymphatic system that makes and trains special white blood cells called T-cells. The T-cells help your immune system fight disease and infection. Your thymus gland produces most of your T-cells before birth.

Detailed explanation-2: -This review demonstrates growing evidence for the hypothesis that endocrine factors from the pituitary and hypothalamus directly influence the development and function of the immune system. Both pituitary and hypothalamic hormones interfere with lymphocyte proliferation and function.

Detailed explanation-3: -The thymus is a primary lymphoid organ essential for the development of T lymphocytes, which orchestrate adaptive immune responses.

Detailed explanation-4: -The thymus produces and secretes thymosin, a hormone necessary for T cell development and production. The thymus is special in that, unlike most organs, it is at its largest in children. Once you reach puberty, the thymus starts to slowly shrink and become replaced by fat.

Detailed explanation-5: -Which endocrine gland regulates immune system development? The hypothalamus is a brain structure that controls the endocrine system.
