Question

hypothalamus and posterior pituitary relationship
the hypothalamus is functionally and anatomically connected to the posterior pituitary lobe by a bridge of
blood vessels
nerve axons
cartilage
bone

Explanation:

The hypothalamus and posterior pituitary are connected by nerve axons. Neurons in the hypothalamus have axons that extend directly into the posterior pituitary. These axons transport hormones (such as oxytocin and antidiuretic hormone) from the hypothalamus to the posterior pituitary for storage and release into the bloodstream. Blood vessels (a vascular connection) are more characteristic of the relationship between the hypothalamus and the anterior pituitary (the hypothalamic - hypophyseal portal system). Cartilage and bone do not form the connection between the hypothalamus and posterior pituitary.

Answer:

nerve axons
