Rugae can be seen within stomach. Anatomical terminology. [edit on Wikidata] Rugae folds behind the anterior teeth in the hard palate of the mouth. In anatomy, rugae (sg.: ruga) are a series of ridges produced by folding of the wall of an organ. [1] Most commonly rugae refers to the gastric rugae of the internal surface of the stomach.
Vaginal rugae are structures of the vagina that are transverse ridges formed out of the supporting tissues and vaginal epithelium in females. [1] Some conditions can cause the disappearance of vaginal rugae and are usually associated with childbirth and prolapse of pelvic structures. The rugae contribute to the resiliency and elasticity of the ...
The gastric folds (or gastric rugae) are coiled sections of tissue that exist in the mucosal and submucosal layers of the stomach. [1] They provide elasticity by allowing the stomach to expand when a bolus enters it. These folds stretch outward through the action of mechanoreceptors, which respond to the increase in pressure. [2]
The epithelium of the vagina, visible at top, consists of multiple layers of flat cells. The vaginal epithelium is the inner lining of the vagina consisting of multiple layers of (squamous) cells. [1][2][3] The basal membrane provides the support for the first layer of the epithelium-the basal layer. The intermediate layers lie upon the basal ...
The gastric mucosa is the mucous membrane layer of the stomach, which contains the gastric pits, to which the gastric glands empty. In humans, it is about one mm thick, and its surface is smooth, soft, and velvety. It consists of simple secretory columnar epithelium, an underlying supportive layer of loose connective tissue called the lamina ...
The term vagina is from Latin vāgīna, meaning "sheath" or "scabbard". [1] The vagina may also be referred to as the birth canal in the context of pregnancy and childbirth. [2] [3] Although by its dictionary and anatomical definitions, the term vagina refers exclusively to the specific internal structure, it is colloquially used to refer to the vulva or to both the vagina and vulva.
The transverse folds of rectum (or Houston's valves or the valves of Houston) are semi-lunar transverse folds of the rectal wall that protrude into the rectum, not the anal canal as that lies below the rectum. Their use seems to be to support the weight of fecal matter, and prevent its urging toward the anus, which would produce a strong urge ...
FMA. 76583. Anatomical terminology. [edit on Wikidata] Gastric pits are indentations in the stomach which denote entrances to 3-5 tubular gastric glands. [1][2] They are deeper in the pylorus than they are in the other parts of the stomach. The human stomach has several million of these pits which dot the surface of the lining epithelium.
