Some kids and teens can control their blood sugar level with dietary changes, exercise, and oral medications, but many will need to take insulin injections like people with type 1 diabetes. In the absence of fertilization, by about 12 days after ovulation, the corpus luteum begins to degenerate, hormone levels fall, and the corpus luteum becomes nonfunctional.
The uterine tubes enter the uterine cavity bilaterally in the superolateral portion of the cavity. Doctors can often treat problems with the endocrine system by controlling the production of hormones or replacing certain hormones with medication.
The outer part, the adrenal cortex, produces hormones called corticosteroids pronounced: Prostate The prostate is a walnut-sized exocrine gland that borders the inferior end of the urinary bladder and surrounds the urethra.
The pituitary gland also controls ovulation and the menstrual cycle in women. These epithelial cells contain many stem cells that divide and form sperm cells through the process of spermatogenesis.
They work together to maintain a steady level of glucose, or sugar, in the blood and to keep the body supplied with fuel to produce and maintain stores of energy.
It is located within the pelvis, anterior to the rectum and posterior to the urinary bladder. For a period of time these two processes overlap. They produce eggs and secrete the female hormones estrogen pronounced: The discharge appears at the vulva and is known as lochia.
The adrenal glands have two parts, each of which produces a set of hormones and has a different function: This technique has some unique advantages and is becoming popular, for example in some equine studs where successful mares can continue their competative careers and still become part of a breeding programme.
Urine exiting the body from the urinary bladder also passes through the urethra. Vestibular bulbs Finally, the vestibular bulbs are 2 masses of erectile tissue that lie deep to the bulbocavernosus muscles bilaterally. The nerve supply is attained through the sympathetic nervous system by way of the hypogastric and ovarian plexuses and the parasympathetic nervous system by way of the pelvic splanchnic nerves from the second through fourth sacral nerves.
Effects of Aging on the Female Reproductive System The female reproductive system consists of the external genital organs and internal genital organs. The penis is roughly cylindrical in shape and contains the urethra and the external opening of the urethra. The upper aspect of the body is dome-shaped and is called the fundus; it is typically the most muscular part of the uterus.
Other more specialised techniques used in breeding include: Erections are controlled by the parasympathetic system through excitatory pathways. The average weight of a nonpregnant, nulliparous uterus is approximately g. Literally translated as "large lips," the labia majora are relatively large and fleshy, and are comparable to the scrotum in males.
Rectouterine ligaments, lying within peritoneal folds, stretch posteriorly from the cervix to reach the sacrum.
Recently other techniques have been developed which permit development of the embryo from a donor animal in a recepient female who will carry the pregnancey to term and nurse the resulting offspring - a technique called embryo transfer.
ESS-truh-jen and progesterone pronounced: Hyperthyroidism is a condition in which the levels of thyroid hormones in the blood are very high. Genital tubercle[ edit ] Mesoderm extends to the midventral line for some distance behind the umbilical cord, and forms the lower part of the abdominal wall; it ends below in a prominent swelling, the cloacal tubercle, which after the separation of the rectum becomes the genital tubercle.
The body of the uterus is responsible for holding a pregnancy, and strong uterine wall contractions help to expel the fetus during labor and delivery. A single spermatazoon penetrates the oocyte and the male and female pronuclei fuse to form an ootid which divides repeatedly to form the blastocyst.
The cells of the adrenal medulla are derived from the same embryonic tissue as sympathetic postganglionic neurons; therefore the medulla is akin to a modified sympathetic ganglion.
Together, these strands are referred to as the cardinal ligament. The urethra passes through the prostate and ends at the external urethral orifice located at the tip of the penis.

The internal organs of the male reproductive system, also called accessory organs, include the following: Epididymis: The epididymis is a long, coiled tube that rests on the backside of each testicle.
