Hypophyseal portal system is a blood system of vessels in the microcirculation at the base of the brain, connecting the hypothalamus with the anterior pituitary. It is involved in quick transportation and exchange of hormones between the hypothalamus arcuate nucleus and the anterior pituitary gland. Hypothalamic-hypophyseal tract comprises of neurons that deliver vesicles with neurohormones from the hypothalamus to the posterior lobe of the pituitary gland. In this case, it is partly contained within the infundibulum (hollow stalk connecting the hypothalamus and the posterior pituitary gland).
<h3>Chemical <u>
bond</u> is the answer. </h3>
Explanation:
A chemically bond is defined as the invisible force between two atoms which together forms a molecule. Chemical bonds are of different types - covalent bond and ionic bond. These bonds are formed between the atoms because of a chemical reaction.
In a chemical reaction, different reaction intermediates are formed which leads to the formation of new forces of attraction between nearby atoms or ions to form new bonds. Thus chemical bonds are formed from chemical reaction.
