Which of the following is an accumulation and release centre of neurohormones?
1 Anterior pituitary lobe
2 Posterior pituitary lobe
3 Intermediate lobe of the pituitary
4 Hypothalamus
Explanation:
The neurohormones in most mammals (like oxytocin and vasopressin) are produced in the hypothalamic region of the brain and secreted into the blood by the neurohypophysis i.e., posterior part of the pituitary gland.

Statement A : Vasopressin acts on the smooth muscles of our body and stimulates their contraction. Statement B : Oxytocin acts mainly at the kidney and stimulates resorption of water and electrolytes by the distal tubules.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.

The hormones from the hypothalmus reach the neurohypophysis via?
1 Axons
2 Portal blood vessels
3 Arterial circulation
4 None of these
Explanation:
Neurohypophysis (pars nervosa) also known as posterior pituitary, stores and releases two hormones called oxytocin and vasopressin, which are actually synthesised by the hypothalamus and are transported axonally to neurohypophysis

The pituitary gland secretes its hormones into
1 Portal circulation
2 Arterial circulation
3 Venous circulation
4 2 and 3
Explanation:
The pituitary gland secretes its secretion/ hormones in to venous circulation, as the deoxygenated blooddrains into the veins, hormones will also flow along to the heart.
