By which structure, hypothalamus is connected with anterior lobe of pituitary gland?
The hypothalamus is connected to the anterior lobe of the pituitary gland via the hypophyseal portal system. This system of blood vessels allows hypothalamic hormones to reach the anterior pituitary directly and regulate its function.
If secretary cells of GHRH are damaged then ......
GHRH (Growth Hormone-Releasing Hormone) stimulates the secretion of growth hormone (GH) from the pituitary gland. GH plays a crucial role in cell division and growth. Therefore, if the secretary cells of GHRH are damaged, the process of cell division will be adversely affected.
Which of the following hormone is directly acting on tissue cells?
STH (Somatotropic Hormone), also known as Growth Hormone (GH), acts directly on tissue cells to stimulate growth and cell reproduction. TSH (Thyroid-Stimulating Hormone), LTH (Luteotropic Hormone), and ACTH (Adrenocorticotropic Hormone) act on other endocrine glands to release their respective hormones.
Which of the following is correct for somato tropic hormone?
Somatotropic hormone (STH) or Growth Hormone (GH) in excess in adults leads to a condition called acromegaly, which causes enlargement of the lower jaw, hands, feet, and other tissues.
Write full form of ACTH?
ACTH stands for Adreno cortico Tropic hormone. ACTH is a hormone produced in the anterior pituitary gland that stimulates the adrenal cortex.
Which of the following option is correct for the location of pineal gland?
The pineal gland is located under the corpus callosum and between the cerebral hemispheres. It is a small endocrine gland in the brain that produces melatonin, which regulates sleep patterns.
Which hormone regulate 24-hr rhythm of our body?
Melatonin is the hormone that regulates the 24-hour rhythm of our body, also known as the circadian rhythm. It is produced by the pineal gland in response to darkness and helps to manage sleep-wake cycles.
It is correct for the functionof pineal gland?
It stimulates reabsorption of water from distal tubule of kidney
Antidiuretic hormone (ADH), also known as vasopressin, is responsible for stimulating the reabsorption of water from the distal tubule and collecting duct in the kidneys. This helps in maintaining the body's water balance and blood pressure.
Which cells are present on the wall of thryoid follicle?
The wall of the thyroid follicle is lined with cuboidal epithelial cells. These cells are involved in the synthesis and secretion of thyroid hormones. When the follicle is inactive, the cells appear more cuboidal, whereas they become columnar when the gland is active.
