An endocrine gland

with parenchyma consisting of both epithelial and neural tissue is being

examined histologically. The epithelial trabeculae contain two types of cells:

chromophilic and chromophobic. Which organ is it?

A patient with

glaucoma has increased intraocular pressure. The secretion of aqueous humor by

the ciliary body is standard. Which structure of the eyeball wall might be

damaged, causing impaired outflow from the anterior chamber?

Most

participants of the Magellan expedition to America died from a form of

avitaminosis. The disease manifested as general weakness, subcutaneous

hemorrhages, tooth loss, and bleeding gums.

Name the

disease.

Blood sampling

for a complete blood count test is recommended to be performed in the morning

and on an empty stomach. What changes in blood composition can occur if the

sample is taken after food intake?

Decreased

blood supply to organs causes hypoxia, which activates the function of

fibroblasts. Which tissue elements are most likely to increase in volume?

The specimen shows

sections of a hematopoietic and immunogenic organ. The organ contains lymphoid

tissue forming various structures such as lymph nodes, lobules, and cords.

Which organ is characterized by the antigen-independent proliferation and

differentiation?

Histological

examination of the thymus of a 40-year-old man revealed a decreased proportion

of parenchymal glandular elements, an increased amount of adipose and loose connective

tissue, and a greater number of Hassall’s corpuscles. The mass of the organ

remained unchanged. What is the most likely phenomenon?

A 22-year-old

patient was admitted to the hospital complaining of heavy nasal breathing.

Examination of the nasal cavity revealed a thickened mucous membrane, excessive

mucus, and nodular infiltrates without erosions. Nasal rhinoscleroma was

diagnosed and a biopsy was taken. What typical morphological changes are likely

to be found?

An electron micrograph shows a macrophage-like cell

with erythrocytes at various stages of differentiation located along its

cellular processes. This cell is most likely located in which organ?

In a histological specimen, the parenchyma of an organ

is composed of lymphoid tissue that forms lymph nodules. These nodules are

arranged diffusely and surround a central artery. Which anatomical structure

has this morphological organization?
