Endocrine System Glands Quiz

Endocrine System Glands

Adenohypophysis refers to the anterior pituitary gland, crucial for hormone production.
Adrenal Cortex is the outer layer of the adrenal gland, responsible for secreting corticosteroids involved in metabolism and immune response.
Adrenal Medulla, the inner part of the adrenal gland, releases catecholamines like epinephrine and norepinephrine, which prepare the body for fight-or-flight responses.
Alpha Cells in the pancreas produce glucagon, a hormone that raises blood glucose levels.
Beta Cells in the pancreas secrete insulin, which lowers blood glucose levels.
Catecholamines are hormones released by the adrenal medulla during stress, impacting cardiovascular and metabolic functions.
Corticosteroids encompass a range of steroid hormones released by the adrenal cortex that regulate various physiological processes.
Delta Cells produce somatostatin, which inhibits the release of other hormones, including insulin.
Endocrine Glands are ductless structures that secrete hormones directly into systemic circulation.
Glucocorticoids like cortisol are key hormones produced by the adrenal cortex, impacting glucose metabolism and immune function.
Gonads are the primary reproductive organs, with testes in males producing sperm and ovaries in females producing eggs and sex hormones.
Graves' disease is an autoimmune disorder that leads to excessive thyroid hormone secretion, causing symptoms like weight loss and hyperactivity.
Hormones are biochemical messengers secreted by glands, regulating various bodily functions.
Hypophyseal Portal System connects the hypothalamus to the anterior pituitary, facilitating direct hormone communication.
Inhibiting Hormones from the hypothalamus decrease secretion of hormones from the anterior pituitary, maintaining hormonal balance.
Islets of Langerhans are specialized regions in the pancreas that contain endocrine cells, regulating blood sugar levels.
Mineralocorticoids, such as aldosterone, regulate sodium and potassium balance and influence blood pressure.
Negative Feedback is a regulatory mechanism that decreases hormone production when the desired effect is achieved, promoting homeostasis.
Neurohypophysis is another name for the posterior pituitary gland, which releases hormones like oxytocin and vasopressin.
Pancreas has dual functions, serving both as an endocrine organ that regulates blood glucose and as an exocrine organ that secretes digestive enzymes.
Parathyroid Glands help maintain calcium homeostasis by secreting parathyroid hormone (PTH), which raises blood calcium levels.
Pineal Gland synthesizes melatonin, a hormone that regulates sleep-wake cycles, with levels fluctuating based on light exposure.
Pituitary Gland controls numerous hormonal activities and is divided into anterior and posterior lobes, each with distinct functions.
Releasing Hormones stimulate the anterior pituitary to release specific hormones, prompting various biological activities.
Sex Steroids include hormones such as testosterone and estrogen, which influence reproductive functions and sexual characteristics.
Target Cells are equipped with specific receptors to respond to particular hormones, ensuring precise physiological responses.
Tetany is a condition of prolonged muscle contraction caused by insufficient calcium levels (hypocalcemia).
Thymus plays a significant role in the immune system by producing hormones that facilitate the development of T-cells.
Thyroid Gland regulates metabolic rate and energy expenditure by releasing hormones such as thyroxine (T4) and triiodothyronine (T3).
