Which of the following is true of the anterior pituitary gland?

(Please select 1 option)

Produces hormones which share a common beta sub-unit Incorrect answer selected

Exhibits a constant hormone secretion activity

Is connected to the thalamus by neural tissue

Produces glycoproteins This is the correct answer

Is contained in the anterior cranial fossa

Explanation

The pituitary stalk connects the posterior pituitary to the hypothalamus and it is contained in the pituitary sella with the optic chiasm and hypothalamus as superior relations.

Glycoproteins such as thyroid-stimulating hormone (TSH) and luteinising hormone (LH) follicle-stimulating hormone (FSH) are produced by the anterior pituitary. These share a common alpha subunit with unique beta subunits.

There is diurnal variation in the secretion of many hormones such as LH, adrenocorticotropic hormone (ACTH) and growth hormone (GH).
