Epithelial Tissue

Epithelial tissue is characterized by its close proximity of cells, with minimal extracellular space between them.

Thymus

The Thymus is a primary lymphoid organ that plays a crucial role in the development of T lymphocytes (T cells).

T Cell Entry into the Thymus

T cells enter the Thymus through blood vessels.

Cortex and Medulla of the Thymus

The cortex of the Thymus is the outer region that is densely packed with immature T cells.
The medulla of the Thymus is the inner region that contains more mature T cells.

T Cell Maturation in the Thymus

The maturation of T cells in the Thymus must occur in a controlled environment to prevent the generation of self-reactive T cells that could attack the body's own tissues.

Thymus Capsule

The thick white capsule surrounding the Thymus serves to isolate the Thymus from external influences and create a protected environment for T cell maturation.

s’Hassall Corpuscles

s’Hassall corpuscles are concentric layers of epithelial cells found in the medulla of the Thymus.
Their function is unclear but may involve the regulation of T cell development and activity.

Keratin-Stained Epithelial Tissues

Keratin-stained epithelial tissues (keratinized) have a unique characteristic of having a tough, protective outer layer of keratin protein.
This distinguishes them from other types of epithelial tissues which lack this feature.

Test your knowledge on identifying different components of the spleen histology, including red and white pulp, trabeculae, and PALS. Practice recognizing the capsule, central artery, T cells, and follicles in spleen tissue sections.
