The hypothalamus has two kinds of outputs to the pituitary gland: directly to the posterior lobe, and indirectly to the anterior lobe (via a capillary plexus). Cell bodies in the supraoptic and paraventricular nuclei project down the pituitary stalk to the posterior lobe, and releasing peptides into the capillaries in the posterior pituitary. This is therefore the correct answer.

a
Posterior lobe of the pituitary
QuestionChoice
This is another name for the anterior pituitary gland. The hypothalamic cell bodies in the supraoptic and paraventricular nuclei do not project to it.

d
Adenohypophysis
QuestionChoice
The cavernous sinus is the structure within which the pituitary is situated. The hypothalamic cell bodies in the supraoptic and paraventricular nuclei do not project to it.

QuestionChoice
Whilst there are axonal projections from the hypothalamus to the medulla, the hypothalamic cell bodies in the supraoptic and paraventricular nuclei project instead to the posterior lobe of the pituitary gland.

e
Medulla oblongata
QuestionChoice
Hypothalamic cell bodies in many other nuclei (parvocellular) have shorter axons that release peptides onto a capillary plexus in the neck of the stalk, projecting down to the anterior lobe of the pituitary. However, the hypothalamic cell bodies in the supraoptic and paraventricular nuclei do not project to the anterior pituitary.

A 35-year-old man presents to an endocrinology clinic with a tumour of the hypothalamus. It is noted that some surrounding structures are also affected.

To which structure do the hypothalamic cell bodies in the supraoptic and paraventricular nuclei project?
a
