Which hormone is responsible for milk formation in mammary gland ?
Prolactin is the hormone responsible for milk formation in the mammary glands. It stimulates the mammary glands to produce milk (lactation) after childbirth.
Who secrete ANF?
The Atrial Natriuretic Factor (ANF) is secreted by the atrial wall of the heart. When the atria of the heart are stretched due to increased blood volume, they release ANF to reduce blood pressure and fluid levels by promoting the excretion of sodium and water by the kidneys.
What is full form of ANF?
The full form of ANF is Atrial Natriuretic Factor. It is a hormone involved in the regulation of blood pressure by promoting the excretion of sodium (natriuresis) and water from the kidneys.
Which of the following option indicates correctly matched group?
The Juxta Glomerular Apparatus (JGA) secretes erythropoietin, a hormone that stimulates the formation of red blood cells (RBCs) in the bone marrow. This is crucial for maintaining adequate levels of RBCs and ensuring sufficient oxygen transport throughout the body.
Which of the following is not secondary messanger?
T4, or Thyroxine, is not a secondary messenger. Secondary messengers are molecules that relay signals received by receptors to target molecules inside the cell. Examples include AMP (Adenosine Monophosphate), IP3 (Inositol Triphosphate), and Ca2+ (Calcium ions). Thyroxine is a primary hormone produced by the thyroid gland and does not function as a secondary messenger.
Which of the following is called hypercalcemic hormone
PTH, or Parathyroid Hormone, is called the hypercalcemic hormone because it increases the level of calcium in the blood. It does this by stimulating the release of calcium from bones, increasing the absorption of calcium in the intestines, and promoting the reabsorption of calcium in the kidneys. Thyroxine (o2) and TCT (Calcitonin, o3) are not involved in increasing blood calcium levels.
Which hormones are directly involve in cardio-vascular activity
Cortisol and catecholamines (such as adrenaline and noradrenaline) are directly involved in cardiovascular activity. Cortisol helps regulate blood pressure and cardiovascular function, while catecholamines increase heart rate and blood pressure during stress responses. Insulin (o1), progesterone (o2), and oestrogen (o4) do not have direct roles in cardiovascular activity.
Which of the following is not peptide protein hormone?
Estradiol is not a peptide/protein hormone. It is a steroid hormone, which belongs to the class of estrogens. On the other hand, Glucagon, Insulin, and FSH (Follicle Stimulating Hormone) are peptide/protein hormones.
Which of the following hormones need secondary messanger for their expression?
Glucagon and insulin both require secondary messengers for their action. Glucagon uses cAMP as a secondary messenger, while insulin uses a signaling pathway involving insulin receptors and subsequent secondary messengers like PI3K and Akt.
Which hormone is secreted by delta cells?
Delta cells, also known as D cells, in the pancreas secrete somatostatin. Somatostatin acts to inhibit the release of both insulin and glucagon.
