Hormones are chemical substances released by endocrine glands that reach the circulation and target cells to coordinate activities throughout the body. There are several classifications of hormones including steroid hormones like cholesterol, sex hormones like androgens and estrogens, adrenal gland hormones like mineralcorticoids, and amino acid derivative hormones like tyrosine. The anterior pituitary gland secretes hormones like LH, ACTH, TSH, FSH, GH, and prolactin, which stimulate other endocrine glands to secrete their own hormones and regulate various bodily functions.

The hypothalamus controls the endocrine system by secreting hormones that stimulate or inhibit the pituitary gland. The pituitary gland then secretes hormones that target other endocrine glands, such as the thyroid, to release additional hormones like thyroxine. Other major endocrine glands include the pancreas, adrenals, ovaries/testes, and pineal gland, each producing hormones unique to their functions in metabolism, stress response, reproduction, and circadian rhythms.
Endocrine System @.pptx
The endocrine system consists of glands that secrete hormones directly into the bloodstream to regulate distant target organs and tissues. The major glands include the pituitary, thyroid, parathyroid, adrenal, pancreas, ovaries, and testes. The pituitary gland is considered the "master gland" as it controls other endocrine glands by producing hormones that stimulate or inhibit their secretions. Hormones travel through the bloodstream to target cells, regulating critical functions like growth, metabolism, mood, fertility, and fluid and mineral balance. Negative feedback loops help maintain optimal hormone levels within a narrow range.
Hormonal cascade system involving hypothalamus
1. The document discusses the hormonal cascade system involving the hypothalamus. It begins with the hypothalamus secreting releasing hormones that stimulate the anterior pituitary gland.
2. The anterior pituitary gland then secretes additional hormones that target various endocrine glands like the thyroid, adrenals, ovaries and testes. These glands ultimately secrete hormones into the bloodstream.
3. There is amplification and negative feedback involved, with hormones from downstream glands inhibiting the previous steps in the pathway once sufficient amounts are present. The document then discusses the various endocrine glands and hormones they secrete.

The document discusses the endocrine system, including the classification and functions of various endocrine glands. It describes the pituitary gland, thyroid gland, parathyroid gland, adrenal gland, pancreas and their associated hormones. The pituitary gland regulates other endocrine glands via releasing hormones from the hypothalamus. The thyroid gland produces thyroxine and triiodothyrone which regulate metabolism. The parathyroid gland and pancreas regulate calcium and blood sugar levels respectively. The adrenal gland regulates stress responses and metabolism through corticosteroids, androgens and adrenaline/noradrenaline.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Hormones
- 1. Hormones
- 2. Hormones Definition: Hormones are chemical substances produced by the endocrine signaling system. They are released from endocrine glands. Hormones reach into the circulation to reach their target site or cell and help in coordinating the activities of the trillions of cells in the body of a multicellular animal.
- 5. Classification of hormones 1) Steroid hormone Eg. Cholesterol 2) Sex hormones Eg. androgens, estrogens and progesterone 3) Adrenal gland hormones Eg. Mineralcoritcosteriods 4) Amino acid derivative hormones Eg. Tyrosine
- 7. Anterior Pituitary Hormones Luteinizing hormone (LH) Adrenocorticotropic hormone (ACTH) Thyroid stimulating hormone (TSH) Follicle stimulating hormone (FSH) Growth hormone (GH) Prolactin (PRL).
- 9. The anterior pituitary hormones may also be called tropic hormones or endocrinokinetic hormones in function, except prolactin, as they act on other endocrine glands or tissues to stimulate them to secrete active substances. The following sections discuss the structure, release and functions of various hormones secreted by anterior pituitary.
