The sample of tissue is immersed in fixative solution for a set period of time. The fixative solution must have a volume at least 10 times greater than the volume of the tissue. [6] In order for fixation to be successful, the fixative must diffuse throughout the entire tissue, so tissue size and density, as well as type of fixative must be ...
Labeled anatomy of the human vulva and nearby structures. The vulva is of all of the external parts and tissues and includes the following: [3] Clitoris: an organ located at the top of the vulva. It consists of the body and its pea-shaped glans that is protected by the clitoral hood.
The tissues of the vulva are highly vascularised and blood supply is provided by the three pudendal arteries. [22] Venous return is via the external and internal pudendal veins . [ 23 ] The organs and tissues of the vulva are drained by a chain of superficial inguinal lymph nodes located along the blood vessels .
The vagina is attached to the pelvic walls by endopelvic fascia. The peritoneum is the external layer of skin that covers the fascia. This tissue provides additional support to the pelvic floor. The endopelvic fascia is one continuous sheet of tissue and varies in thickness. It permits some shifting of the pelvic structures.
The first step of plastination, fixation, [4] frequently uses a formaldehyde-based solution, and serves two functions. Dissecting the specimen to show specific anatomical elements can be time-consuming. Formaldehyde or other preserving solutions help prevent decomposition of the tissues. They may also confer a degree of rigidity.
In human anatomy, and in mammals in general, the mons pubis or pubic mound (also known simply as the mons / m ɒ n z /, and known specifically in females as the mons Venus or mons veneris) [1] [2] is a rounded mass of fatty tissue found over the pubic symphysis of the pubic bones.
In some instances, extra tissue is needed to reconstruct or construct the vagina. These grafts used in vaginoplasty can be an allotransplantation , a heterograft , or an autologous material. [ 9 ] [ 10 ] A woman can use an autologous in vitro cultured tissue taken from her vaginal vestibule as transplanted tissue to form the lining of the ...
Vaginal rugae disappear in older women and those with an estrogen deficiency. [7] The rugae can disappear with anterior vaginal wall prolapse which can occur when supports to the portion located between the vagina and bladder are damaged and the bladder bulges into the vaginal lumen.
