Which hormones secreted by developing follicles?
Residual cells within ovulated folliclesproliferate to form corpora lutea, which secrete the steroid hormones progesterone and estradiol (estrogen).
How does progesterone play a role in a feedback mechanism?
"The corpus luteum synthesizes progesterone, estradiol, and 17-hydroxyprogesterone. The increased progesterone levels affect the thermoregulatory site in the hypothalamus and increase the core body temperature. Negative feedback from the increased release of estradiol and progesterone from the corpus luteum results in decreased serum LH and FSH levels in the luteal phase. If conception has not occurred, FSH levels increase again at the end of the luteal phase as the progesterone and estradiol levels decrease. The decrease in progesterone and estradiol levels results in shedding of the endometrium-i.e., menstruation. LH pulse frequency is high (90 minutes) and of low amplitude in the follicular phase. The pulse frequency and amplitude increase immediately before ovulation".
Which part of the endocrine system already male reproductive glands?
The male reproductive glands are primarily the testes, which are part of the endocrine system as they produce hormones, particularly testosterone. The testes are responsible for the production of sperm and the secretion of hormones that regulate male secondary sexual characteristics and reproductive functions. Additionally, the hypothalamus and pituitary gland play crucial roles in regulating the function of the testes through the release of gonadotropins.
Glandular secretion associated with?
The glandular secretion is associated with pocrine, holocrine, and merocrine.
What condition occurs when there is an increase in estrogen secretion by the adrenal cortex of males?
Increased estrogen secretion by the adrenal cortex in males can lead to a condition called gynecomastia, which is the development of breast tissue in males. This can result in breast enlargement or tenderness. It is important to consult a healthcare provider for proper evaluation and management.
What inhibits secretion of LH and FSH?
Progesterone
What hormones are realeased from the ovaries?
The ovaries produce a couple of gonadal hormones. One of these, estrogen, promotes the secondary sex characteristics and sex drive. Another is progesterone which prepares the uterus for pregnancy. Another hormone called in inhibin inhibits the secretion of follicle stimulating hormone.
What does LH hormone do?
It's a protein that regulates secretion of progesterone in women and controls the maturation of Graafian follicles, ovulation and initiation of the corpus luteum. In men it stimulates the Leydig cells to produce testosterone which is the hormone responsible for the appearance of secondary sexual characteristics of male and the sexual appetite.
Causes the endometrial glands to begin the secretion of nutrients?
Progesterone
What processes in the monthly reproductive cycle of the female occurs simultaneously?
a.maximal LH secretion and menstruation b.maximal steroid secretion by the corpus luteum and menstruation c.early follicular development and the secretory phase in the uterus d.degeneration of the corpus luteum and a decrease in ovarian progesterone secretion
During the secretory phase of the menstrual cycle?
progesterone secretion is at its highest
What hormone causes the endometrial glands to begin the secretion of nutrients?
progesterone.
Exert negative feedback on the anterior pituitary relative to fsh secretion?
Estrogen and progesterone.
Is secondary hyperparathyroidism caused by excessive parathyroid secretion?
False
What are the secondary sex characteristics that are caused by estrogen?
There are many secondary sexual characteristics caused by testosterone, including growth of facial, chest, and armpit hair. Enlargement of the voice box leading to an Adam's apple and a deeper voice. Broadening of the shoulders. Increased secretion of the sweat, and oil glands. Increased muscle mass.
Is there still secretion on the day of ovulation if you get pregnant?
No, women do not ovulate stop during pregnancy (inhibited by high levels of estrogen and progesterone)
What condition of arrested physical and mental development results from a congenital lack of thyroid secretion?
Arrested physical and mental development resulting from a congenital lack of thyroid secretion is known as Cretinism.
