In 1998, skeletal muscle was identified as an endocrine organ [14] due to its now well-established role in the secretion of myokines. [14] [15] The use of the term myokine to describe cytokines and other peptides produced by muscle as signalling molecules was proposed in 2003. [16]
The TRH stimulates the anterior pituitary to produce thyroid-stimulating hormone (TSH). The TSH, in turn, stimulates the thyroid to produce thyroid hormone until levels in the blood return to normal. Thyroid hormone exerts negative feedback control over the hypothalamus as well as anterior pituitary, thus controlling the release of both TRH ...
Both hormones exert their effects principally on the collecting ducts. Tubular secretion occurs simultaneously during re-absorption of filtrate. Substances, generally produced by body or the by-products of cell metabolism that can become toxic in high concentration, and some drugs (if taken). These all are secreted into the lumen of renal tubule.
These dimeric glycoprotein hormones, primarily produced by granulosa cells in the ovary, act as negative feedback regulators of FSH secretion from the anterior pituitary. During the follicular phase, inhibin B is the predominant form, with its levels rising in parallel to the growth of the dominant follicle.
Gigantism and acromegaly caused by an excess of growth hormone in childhood and adult, respectively; Hypothyroidism caused by a deficiency of thyroid-stimulating hormone; Hyperpituitarism, the increased (hyper) secretion of one or more of the hormones normally produced by the pituitary gland
The parvocellular is involved in controlling the secretion of hormones from the anterior pituitary. Anterior Pituitary: The main role of the anterior pituitary gland is to produce and secrete tropic hormones. [6] Some examples of tropic hormones secreted by the anterior pituitary gland include TSH, ACTH, GH, LH, and FSH.
Erythropoiesis (from Greek 'erythro' meaning "red" and 'poiesis' "to make") is the process which produces red blood cells (erythrocytes), which is the development from erythropoietic stem cell to mature red blood cell. [1] It is stimulated by decreased O 2 in circulation, which is detected by the kidneys, which then secrete the hormone ...
Interaction of hormones at target cells Permissiveness is the situation in which a hormone cannot exert its full effects without the presence of another hormone. Synergism occurs when two or more hormones produce the same effects in a target cell and their results are amplified.
