Endocrine and Reproductive Systems and Development
Question 1A. Discuss how the pancreatic endocrine hormones glucagon and insulin work antagonistically to maintain homeostasis in the body during times of feast and times of famine.
Insulin and glucagon are polypeptides from the Islets of Langerhans of the pancreas. The two hormones collectively regulate the intermediary metabolism of proteins, carbohydrates, and fats. Insulin has anabolic properties such increasing the storage of fatty acids, glucose, and amino acids. Glucagon, on the contrary, is catabolic, causing mobilization of fatty acids, amino acids, and glucose from the tissues into the blood. The duo is a reciprocal of their net action and release (Ganong 315). After meal or infusion …show more content…
Most pills mixtures comprise of progestin and estrogen taken orally for 21 days each packet has exact 21 tablets. The drug inhibits ovulation through tampering with gonadotropin- releasing hormone and modifies the uterus preventing implantation. The pill also makes the cervical mucus thick and impermeable to sperms. Pill is the most effective with regular menses and effective against dysmenorrhea (Hamilton-Fairley 47 and 48).
The second category is the intrauterine contraceptive devices including copper and progesterone bearing device. Copper inhibits sperm motility. Gives long lasting protection with minimal attention at intercourse. The barrier has little complication. However, insertion requires skilled personnel. Mild pain and bleeding may be present during insertion (Hamilton-Fairley 51). The devices may cause excessive blood loss, unknown dysmenorrhea, and irregular bleeding (Falcone and Hurd 410).
The third contraception method is the barrier, which involve the use of diaphragm, cervical cap, vaginal sheath jellies, and vault pessary. The barrier devices prevent the entry of sperms into the cervix but require spermicide supplementation for effective results. The woman can insert it by herself after training
