Question

Thymic corpuscles are always found in the lighter-colored ________ regions of the thymus.

A) Cortex
B) Medulla
C) Parenchyma
D) Capsule

Answer 1

Thymic corpuscles are found in the lighter-colored medulla regions of the thymus. The medulla is less densely packed than the cortex, which is why it has a lighter appearance.

Step-by-step explanation:

Thymic corpuscles are always found in the lighter-colored medulla regions of the thymus. This is in contrast to the cortex, which is densely packed and, therefore, stains more intensely. The medulla contains a less dense collection of thymocytes, epithelial cells, and dendritic cells, making it appear lighter in color.
