Chromaffin cells are present in
ব্যাখ্যা
Adrenal Medullary parenchymal cells, known as chromaffin cells, arise from neural crest cells, as do the postganglionic neurons of sympathetic and parasympathetic ganglia. Chromaffin cells can be considered modified sympathetic postganglionic neurons, lacking axons and dendrites and specialized as secretory cells.

Regarding histology of thyroid gland-
ব্যাখ্যা
-Follicular cells are columnar when stimulated
-Parafollicular cells are larger than follicular cells

Which is a content of both superior and posterior mediastinum?
১৩.
Induction of central tolerance occurs in-
ব্যাখ্যা
Function of thymus:
1.Production, differentiation and maturation and maturation of T-lymphocytes
2.Secretion of thymopoietin by epithelioreticular cells. Thymopoietin stimulates T cell production.
3.Thymus is essential for development of immunity in early life.
4. Another main function of the thymus is induction of central tolerance, which along with regulatory T cells prevents autoimmunity

The paracortex of lymph nodes can be identified by-
ব্যাখ্যা
Paracortex:
The region between the cortex and medulla, the paracortex or deep cortex does not have precise boundaries but can be distinguished from the outer cortex by its lack of nodules (B-lymphocytes). Paracortex mainly consists of T cells; hence, it is also called thymus-dependent cortex.
