Which of the following structures connects hypothalamus to the anterior lobe of the pituitary gland?

• A. Dendrites of neurohypophysis
• B. Axons of neurohypophysis
• C. Bands of white fibres from cerebellar region
• D. Hypophyseal portal system

Answer 1

The correct option is D Hypophyseal portal system

Within the infundibulum is a bridge of capillaries that connects the hypothalamus to the anterior pituitary. This network is called the hypophyseal portal system. It allows hypothalamic hormones to be transported to the anterior pituitary without first entering the systemic circulation.
