What is a primary characteristic of hormones classified under FLAT?

• A. They are all tropic hormones
• B. They promote local cellular response
• C. They are synthesized in the pancreas
• D. They directly impact target tissues

Answer: (A)

Hormones classified under the acronym FLAT — which stands for Follicle-stimulating hormone (FSH), Luteinizing hormone (LH), Adrenocorticotropic hormone (ACTH), and Thyroid-stimulating hormone (TSH) — are characterized primarily as tropic hormones. These hormones are secreted by the anterior pituitary gland and have the main function of stimulating other endocrine glands to produce and release their own hormones. This connection is crucial in understanding the endocrine system's regulatory mechanisms. Tropic hormones serve to control various physiological processes by influencing other glands rather than acting directly on non-endocrine tissues. Therefore, their primary role in the body is not to elicit immediate changes in target tissues directly but to regulate and coordinate the functioning of other glands, enabling a cascade of hormonal effects throughout the body. The other options do not accurately describe the FLAT hormones. They do not promote local cellular responses, as they primarily function at a systemic level by signaling other endocrine glands. They are not synthesized in the pancreas, which is primarily involved in producing insulin and glucagon, and these hormones do not directly impact target tissues; instead, they rely on secondary messengers to influence cellular responses following their signaling to other glands
