corpus collosum

Examples of corpus collosum in the following topics:

• Ovarian Cycle

  • It begins with the formation of the corpus luteum and ends in either pregnancy or luteolysis.
  • The hormones produced by the corpus luteum also suppress production of the FSH and LH that the corpus luteum needs to maintain itself.
  • With continued low levels of FSH and LH, the corpus luteum will atrophy.
  • The death of the corpus luteum results in falling levels of progesterone and estrogen.
  • The loss of the corpus luteum can be prevented by implantation of an embryo.

• White Matter of the Cerebrum

  • The great majority of commissural tracts pass through the large corpus callosum.
  • The corpus callosum (Latin: "tough body"), also known as the colossal commissure, is a wide, flat bundle of neural fibers beneath the cortex in the eutherian brain at the longitudinal fissure.
  • The posterior portion of the corpus callosum is called the splenium, the anterior is called the genu (or "knee"), and the area between the two is the truncus or body of the corpus callosum.
  • The rostrum is the part of the corpus callosum that projects posteriorly and inferiorly from the anteriormost genu.
  • Agenesis of the corpus callosum (ACC) is a rare congenital disorder in which the corpus callosum is partially or completely absent.

• Hormonal Regulation of the Female Reproductive Cycle

  • The luteal phase begins with the formation of the corpus luteum stimulated by FSH and LH and ends in either pregnancy or luteolysis.
  • The hormones produced by the corpus luteum also suppress production of the FSH and LH, which leads to its atrophy.
  • The death of the corpus luteum results in falling levels of progesterone and estrogen, which triggers the end of the luteal phase.
  • Alternatively, the loss of the corpus luteum can be prevented by implantation of an embryo: after implantation, human embryos produce human chorionic gonadotropin (hCG).
  • Human chorionic gonadotropin is structurally similar to LH and can preserve the corpus luteum.

• Penis

  • The human penis is made up of three columns of tissue: 1) Two corpora cavernosa that lie next to each other on the dorsal side and, 2) a corpus spongiosum that lies between the corpora cavernosa on the ventral side.
  • The glans penis is the bulbous end of the penis formed by the corpus spongiosum.
  • The urethra is the last part of the urinary tract and traverses the corpus spongiosum.

• Hemispheric Lateralization

  • A longitudinal fissure separates the human brain into two distinct cerebral hemispheres connected by the corpus callosum.
  • Patients with split-brain are individuals who have undergone corpus callosotomy, a severing of a large part of the corpus callosum (usually as a treatment for severe epilepsy).
  • The corpus callosum connects the two hemispheres of the brain and allows them to communicate.

• Erectile Dysfunction and the Blue Pill

  • The corpus cavernosum penis is one of a pair of sponge-like regions of erectile tissue which contain most of the blood in the penis during penile erection.

• Implantation

  • The syncytiotrophoblast also produces human chorionic gonadotropin (hCG), a hormone that "notifies" the mother's body that she is pregnant, preventing menstruation by sustaining the function of the progesterone-producing corpus luteum within the ovary.

• Oogenesis

  • The empty follicle then forms a corpus luteum which later releases the hormone progesterone to maintain the potential pregnancy.

• Pubis

  • The rough superior edge of the corpus, known as the pubic crest, ends laterally in the pubic tubercle.

• Male Sexual Response

  • Physical or psychological stimulation, or both, leads to vasodilation in and the increased blood flow into the three spongy areas that run along the length of the penis (the two corpora cavernosa and the corpus spongiosum).
