What is oogenesis? Oogenesis is a type of gametogenesis. It is the process of producing female gametes, once sex determination of the embryo has occurred. The presence of the SRY gene on the Y chromosome leads to male gonad formation and spermatogenesis, while female gonad development is the âdefault stateâ.
One type of twist or kink is called a small bowel obstruction. This usually happens after a patient has had an abdominal operation like appendectomy, hysterectomy, or colon removal which leads to scar tissue or adhesions developing in the abdomen. The intestines can be come twisted, kinked, or obstructed around this scar tissue. This condition, called a small bowel obstruction, may require surgery for treatment in 20% of patients. Small bowel obstruction can also occur as the result of a hernia. Another type of intestinal twist is called a volvulus. This usually occurs in the colon, where a segment of the colon rotates 180 degrees like a roller coaster loop. This causes a blockage of the colon and may pinch off the blood supply to the colon.
Ocular Wound Healing. The ocular fibrotic wound-repair response is quite similar to that seen in other tissues in the human body. In the eye, fibrotic scarring most commonly occurs in the conjunctiva, cornea, iris, lens, retina, and choroid (Figure 2). In vascularized ocular tissues, like the conjunctiva, iris, choroid, or even the cornea or retina after having chronic ocular disease, fibrovascular scars are basically granulation tissue.
