The location of adrenal glands in the human body. Introduction: The adrenal glands, also referred to as the fight or flight glands, contain two endocrine organs, namely the adrenal medulla and the adrenal cortex. These two organs surround each other, with adrenal medulla assuming the interior, and adrenal cortex assuming the exterior position. The adrenal medulla is a sympathetic ganglion, in which the neurons have lost axons and become secretory cells. It is derived from neuroectoderm and comprises of chromaffin cells. This layer occupies 28% of the adrenal gland, whereas the rest is occupied by adrenal cortex. The adrenal cortex is composed of cortical cells which synthesize and secrete a variety of corticosteroids. It is further divided into three layers, namely, zona fasciculate, zona glomerulosa, and zona reticularis. It occupies 80% of the adrenal glands.

Using information from the primary literature (several references have been provided as a starting point below) please answer the following question: Based on your review of the literature on rewilding, what are the major scientific pros and cons for rewilding? Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions. Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly. Recall Nietzche’s…
