1

Adenohypophysis derives from the ectoderm of the primary oral cavity

1

There are three parts in the adenohypophysis

1

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

1

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

1

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

1

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

1

Gonadotropic cells refer to the acidophilic cells of adenohypophysis.

1

Calcitonin and parathormone have antagonistic function.

1

Parafollicular cells have mesoblastic origin.

1

The function of parafollicular cells is regulated from adenohypophysis.

1

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

1

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

1

Secretory cells in epiphysis are pituicytes.

1

There are two lobes in the thyroid gland.

1

Iodine is needed for the synthesis of the parafollicular hormone.

1

Melatonin is secreted by the cells of epiphysis.

1

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

1

What kind are the capillaries of the hypophysis?

The hormones of neurohypophysis are produced from cells located in:

1

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

1

For the epiphysis is characteristic:

1

The system of the hypothalamic-adenohypophysis blood supply is called

1

B cells in the endocrine pancreas represent % of the islets of Langerhans and produce the hormone

1

The secretory cells of the epiphysis are and produce the hormone and
