The image is a page from a textbook, likely biology or physiology, discussing the endocrine system. The page is primarily text with a diagram illustrating the hormones secreted by the adrenal cortex. The diagram shows a central representation of the adrenal gland, divided into cortex and medulla. Arrows point from the cortex to three categories of hormones: Glucocorticoids, Mineralocorticoids, and Sex hormones. Below Glucocorticoids, functions like raising blood glucose and gluconeogenesis are listed. Mineralocorticoids are linked to controlling potassium excretion and sodium reabsorption. Sex hormones are further divided into Androgens and Oestrogens, with their functions related to secondary sex characteristics and nitrogen metabolism. The text elaborates on these hormones. "The mineralocorticoids" section details Aldosterone's role in electrolyte balance, specifically sodium reabsorption and potassium excretion, and mentions the influence of blood sodium levels and Angiotensin. "The sex hormones" section states that the adrenal cortex produces testosterone, oestrogens, and progesterone in both sexes, and that these hormones are important until the testes and ovaries mature. It also notes that their secretion is controlled by ACTH. Two functions are listed, concerning secondary sex characteristics and protein deposition. The final section, "THE ADRENAL MEDULLA," describes the medulla as an outgrowth of nervous tissue that produces catecholamines like adrenalin and noradrenalin when stimulated by sympathetic neurons. These hormones are noted to potentiate sympathetic stimulation. Three main effects of adrenalin and noradrenalin are listed: dilatation of coronary arteries, dilatation of bronchi, and dilatation of blood vessels to skeletal muscles. Visible text includes chapter information ("THE ENDOCRINE SYSTEM 223"), figure number and caption ("Figure 14:12 The hormones secreted by the cortex of the adrenal gland and their main functions."), and section headings and bullet points as described above. The page is a standard textbook page, likely from a print publication, and the setting is educational. There are no people, specific weather, or time of day cues visible. The image is a close-up of the text and diagram, suggesting it's part of a larger document. in Jalingo, Nigeria
