How changes in the environment could be related to mass extinctions?

Biology
1 answer:
Neko [114]3 years ago
6 0

Answer:

Climate change?

Explanation:

A massive extinction event that took place 200 million years ago may have been caused by climate change, new research suggests. The findings shed new light on the pace of mass extinction, and imply that relatively small changes in atmospheric carbon dioxide levels may be enough to trigger an extinction event.

Where are the hormones oxytocin and antidiuretic hormone (adh) stored?
a_sh-v [17]

The axon terminals of neurons of the hypothalamic-hypophyseal tracts store and secrete ADH and oxytocin in the capillaries of the inferior hypophyseal artery.

<h3>Hypophyseal artery:</h3>

The infundibulum of the pituitary gland, the pars tuberalis, and the median eminence are all supplied by the superior hypophyseal artery. It is a branch of the internal carotid artery's cerebral portion. In order to supply the hypothalamus, the superior hypophyseal arteries split off from the internal carotid arteries, forming a capillary network in the median eminence that is not protected by the blood-brain barrier. The infundibular plexuses and the stalk, respectively, are the sources of the long and short hypophyseal portal veins.

The C6 section of the internal carotid artery gives rise to the superior hypophyseal artery (or arteries). Within 5 mm of the ocular artery's origin, it often arises as a single trunk from the internal carotid artery's medial or posteromedial side.
