It is required for differentiation of T-cells?
Thymosin is a hormone required for the differentiation of T-cells. T-cells are a type of white blood cell that play a central role in the immune response. Thymosin is produced by the thymus gland and is crucial for the maturation of T-cells.
Which hormone is secreted by Zona fasciculata?
Glucocorticoids are secreted by the Zona fasciculata, which is the middle layer of the adrenal cortex. These hormones are involved in the regulation of metabolism and immune response. Cortisol is one of the primary glucocorticoids produced in this layer.
Column I (Name of Functions glands) (a) Posterior pituitary (b) Adrenal medulla (c) parathyroid (d) Ovary (e) Adrenal cortex Column II (Name of Hormones ) (i) Relaxin (ii)Catecholamines (iii) Glucocortecoids (iv) Oxytocin (v) PTH Column III (Functions) (f) Regulate corbohydrate pituitary metabolism. (g)Milk secretion frommammarygland (h) Decrease Cad+2d absorption from food absorption from digested food (i) Increase Cad+2dcortex absorption from digested food (j) Relax cervix of the uterus (k) Pupilary dilation
To match the glands, hormones, and functions correctly, we need to understand the role of each gland and the hormone it secretes.
Thus, option o4 correctly matches these glands, hormones, and their functions.
Which hormone’s secretion increases in emergency?
During emergencies, the body's 'fight or flight' response is triggered, which involves the release of Adrenaline (also known as epinephrine) from the Adrenal medulla. This hormone prepares the body to respond to stressful situations by increasing heart rate, blood flow to muscles, and energy availability.
Which of the following secretes mineralocorticoids?
Mineralocorticoids, such as aldosterone, are secreted by the Zona glomerulosa of the adrenal cortex. These hormones are crucial for maintaining electrolyte balance and blood pressure by regulating sodium and potassium levels in the blood.
Which of the following stimulates adrenal gland in an emergency?
In an emergency, the central nervous system (CNS) stimulates the adrenal gland. The CNS sends signals to the adrenal medulla, which then secretes adrenaline and noradrenaline to prepare the body for a 'fight or flight' response.
Under secretion of which hormone can cause diabetes mellitus?
Diabetes mellitus is caused by the under secretion of insulin. Insulin is a hormone produced by the pancreas that helps to regulate blood sugar levels. When the body does not produce enough insulin, blood sugar levels remain high, leading to diabetes mellitus.
Which gland atrophies after puberty?
The thymus gland atrophies after puberty. It is very active during childhood and puberty, playing a crucial role in the development of the immune system. However, after puberty, it gradually shrinks and is replaced by fat.
Which of the following hormones are concerned with osmoregulation?
Which hormone regulates colour of skin?
MSH (Melanocyte-Stimulating Hormone) regulates the color of the skin by stimulating the production and release of melanin in melanocytes. This hormone is responsible for skin pigmentation. Therefore, the correct option is o1.
