Why do the navajo associate the tips of the fingers with the trail of the wind?
kozerog [31]
Allegedly, <span>the finger tips show where the wind blew when our ancestors were created. In a way, their fingertips are roots to their ancestors, so touching them somehow links them to their ancestors. And as you probably know, the Navajo are very much connected to their ancestors, and tribes in general. </span>

Anuta_ua [19.1K]

The thyroid is an endocrine gland that regulates metabolic function through the production of all of the following hormones except: Thyroliberin.

Thyrotropin is a peptide secreted by the anterior pituitary gland that prompts the thyroid gland to release thyroxine. It is also known as thyroliberin and thyroid-stimulating hormone (TSH) Thyrotropin-releasing factor, a peptide located in the hypothalamus of the brain and affecting glandula thyroidea secretion, acts to cause the release of TSH.

In vivo, thyrotropin controls thyroid development favourably. The gland becomes hypoplastic in its absence, either as a result of a pituitary disorder or as a side effect of thyroid hormone therapy, with a reduction in the quantity and size of thyrocytes.
