Endocrine System Anatomy PMU 2nd Year

Adenohypophysis derives from the ectoderm of the primary oral cavity

There are three parts in the adenohypophysis

Lobus pyramidalis is not an obligatory part of the thyroid gland.

Acidophilic cells constitute 30-40% of the cell composition of adenohypophysis.

The islets of Langerhans are mostly located in the head of pancreas.

Secretion of Langerhans’ island cells is regulated by the adenohypophysis.

Gonadotropic cells refer to the acidophilic cells of adenohypophysis.

Calcitonin and parathormone have antagonistic function.

Parafollicular cells have mesoblastic origin.

The function of parafollicular cells is regulated from adenohypophysis.

The cells of the zona reticularis of the adrenal gland produce aldosterone.

The cells of zona glomerulosa in suprarenal gland are functionally related with the juxtaglomerular apparatus of the kidney

Secretory cells in epiphysis are pituicytes.

There are two lobes in the thyroid gland.

Iodine is needed for the synthesis of the parafollicular hormone.

Melatonin is secreted by the cells of epiphysis.

Mitochondria with tubulo-vesicular folds are characteristic for the cells of the gland:

What kind are the capillaries of the hypophysis?

The hormones of neurohypophysis are produced from cells located in:

In the chromophilic cells o adenohypophysis are stained with different staining:

Herring bodies are:

In normal function of the thyroid gland, thyrocytes in follicles are:
