It is released in a rhythmic fashion every 60 to 120 minutes. GnRH stimulates the pituitary gland to produce follicle stimulating hormone (FSH), the hormone responsible for starting follicle (egg) development and causing the level of estrogen, the primary female hormone, to rise.
What is the target gland for FSH?
| Endocrine gland/ source of hormone Hormone Target organ or tissue | Anterior pituitary (adenohypophysis) FSH (follicle stimulating hormone) Ovaries / testes (tubules) | LH (luteinizing hormone) Ovaries / testes (Leydig cells) | GH (growth hormone) All tissues | TSH (thyroid stimulating hormone) Thyroid gland |
|---|
Which pituitary gland releases FSH?
Gonadotrophin-releasing hormone is released from the hypothalamus and binds to receptors in the anterior pituitary gland to stimulate both the synthesis and release of follicle stimulating hormone and luteinising hormone.
What gland releases TSH and FSH?
Thyroid stimulating hormone is produced and released into the bloodstream by the pituitary gland . It controls production of the thyroid hormones, thyroxine and triiodothyronine, by the thyroid gland by binding to receptors located on cells in the thyroid gland.
What gland in the brain produces FSH?
The major hormones produced by the pituitary gland are: ACTH: Adrenocorticotrophic hormone. Stimulates the production of cortisol, a “stress hormone” that maintains blood pressure and blood sugar levels. FSH: Follicle-stimulating hormone.
What stimulates FSH release?
GnRH stimulates the pituitary gland to produce follicle stimulating hormone (FSH), the hormone responsible for starting follicle (egg) development and causing the level of estrogen, the primary female hormone, to rise.
Where is FSH secreted from?
FSH is made by your pituitary gland , a small gland located underneath the brain. FSH plays an important role in sexual development and functioning. In women, FSH helps control the menstrual cycle and stimulates the growth of eggs in the ovaries.
Which gland or organ secretes epinephrine and aldosterone?
| Endocrine Gland Associated Hormones Effect | Adrenal (cortex) aldosterone increases blood Na + levels | cortisol, corticosterone, cortisone increase blood-glucose levels | Adrenal (medulla) epinephrine, norepinephrine stimulate fight-or-flight response | Pancreas insulin reduces blood-glucose levels |

What adrenal gland produces norepinephrine and epinephrine?
The adrenal medulla , the inner part of an adrenal gland, controls hormones that initiate the flight or fight response. The main hormones secreted by the adrenal medulla include epinephrine (adrenaline) and norepinephrine (noradrenaline), which have similar functions.
What does posterior pituitary secrete?
The posterior lobe produces two hormones, vasopressin and oxytocin . These hormones are released when the hypothalamus sends messages to the pituitary gland through nerve cells. Vasopressin is also known as antidiuretic hormone (ADH).
What gland releases TSH?
The hypothalamus releases thyrotropin-releasing hormone (TRH), which stimulates the pituitary gland to release thyroid-stimulating hormone (TSH).
What does pituitary gland secrete?
The pituitary gland secretes multiple hormones, including melanocyte-stimulating hormone (MSH, or intermedin), adrenocorticotropic hormone (ACTH), and thyrotropin (thyroid-stimulating hormone, or TSH).
Which endocrine glands secretes calcitonin?
Calcitonin is a hormone that is produced and released by the C-cells of the thyroid gland . Its biological function in humans is to have a relatively minor role in calcium balance.
What is the pineal gland?
The pineal gland was described as the “Seat of the Soul” by Renee Descartes and it is located in the center of the brain. The main function of the pineal gland is to receive information about the state of the light-dark cycle from the environment and convey this information to produce and secrete the hormone melatonin.
Which gland stores its hormone before their release?
Two hormones are produced by the hypothalamus and then stored in the posterior pituitary gland before being secreted into the bloodstream.
What gland is estrogen secreted from?
| Where the hormone is produced Hormone(s) secreted | Ovaries Estrogen | Ovaries Progesterone | Parathyroid glands Parathyroid hormone (PTH) | Thyroid gland Thyroid hormone |
