Corpus Cavernosum Of Clitoris
The corpus cavernosum of the clitoris is one of a pair of sponge-like regions of erectile tissue that engorge with blood during an erection. This is homologous to the corpus cavernosum of the penis. The term ''corpora cavernosa'' literally means "cave-like bodies". Structure The two corpora cavernosa are expandable erectile tissues of the clitoris. They are joined together along their medial surfaces by an incomplete fibrous septum. Each corpus cavernosum is connected to the rami of the pubis and ischium by a clitoral crus. There is connection to the ischiocavernosus muscle. Each can be up to 7 cm long in an adult. Development The corpus cavernosum is homologous to the corpus cavernosum penis in the male. It develops from the genital tubercle in the embryo. The clitoris also has two vestibular bulbs beneath the skin of the labia minora (at the entrance to the vagina), which expand at the same time as the glans clitoridis to cap the ends of the corpora cavernos ...

Clitoris
In amniotes, the clitoris ( or ; : clitorises or clitorides) is a female sex organ. In humans, it is the vulva's most erogenous zone, erogenous area and generally the primary anatomical source of female Human sexuality, sexual pleasure. The clitoris is a complex structure, and its size and sensitivity can vary. The visible portion, the glans, of the clitoris is typically roughly the size and shape of a pea and is estimated to have at least 8,000 Nerve, nerve endings. * * Peters, B; Uloko, M; Isabey, PHow many Nerve Fibers Innervate the Human Clitoris?

Connective Tissue
Connective tissue is one of the four primary types of animal tissue, a group of cells that are similar in structure, along with epithelial tissue, muscle tissue, and nervous tissue. It develops mostly from the mesenchyme, derived from the mesoderm, the middle embryonic germ layer. Connective tissue is found in between other tissues everywhere in the body, including the nervous system. The three meninges, membranes that envelop the brain and spinal cord, are composed of connective tissue. Most types of connective tissue consists of three main components: elastic and collagen fibers, ground substance, and cells. Blood and lymph are classed as specialized fluid connective tissues that do not contain fiber. All are immersed in the body water. The cells of connective tissue include fibroblasts, adipocytes, macrophages, mast cells and leukocytes. The term "connective tissue" (in German, ) was introduced in 1830 by Johannes Peter Müller. The tissue was already recognized as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endothelium
The endothelium (: endothelia) is a single layer of squamous endothelial cells that line the interior surface of blood vessels and lymphatic vessels. The endothelium forms an interface between circulating blood or lymph in the lumen and the rest of the vessel wall. Endothelial cells in direct contact with blood are called vascular endothelial cells whereas those in direct contact with lymph are known as lymphatic endothelial cells. Vascular endothelial cells line the entire circulatory system, from the heart to the smallest capillaries. These cells have unique functions that include fluid filtration, such as in the glomerulus of the kidney, blood vessel tone, hemostasis, neutrophil recruitment, and hormone trafficking. Endothelium of the interior surfaces of the heart chambers is called endocardium. An impaired function can lead to serious health issues throughout the body. Structure The endothelium is a thin layer of single flat (squamous) cells that line the inter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vagina
In mammals and other animals, the vagina (: vaginas or vaginae) is the elastic, muscular sex organ, reproductive organ of the female genital tract. In humans, it extends from the vulval vestibule to the cervix (neck of the uterus). The #Vaginal opening and hymen, vaginal introitus is normally partly covered by a thin layer of mucous membrane, mucosal tissue called the hymen. The vagina allows for Copulation (zoology), copulation and birth. It also channels Menstruation (mammal), menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle. To accommodate smoother penetration of the vagina during sexual intercourse or other sexual activity, vaginal moisture increases during sexual arousal in human females and other female mammals. This increase in moisture provides vaginal lubrication, which reduces friction. The texture of the vaginal walls creates friction for the penis during sexual intercourse and stimulates it toward ejaculation, en ...

Human Skin
The human skin is the outer covering of the body and is the largest organ of the integumentary system. The skin has up to seven layers of ectodermal tissue (biology), tissue guarding Skeletal muscle, muscles, bones, ligaments and organ (anatomy), internal organs. Human skin is similar to most of the other mammals' skin, and it is very similar to pig skin. Though nearly all human skin is covered with hair follicles, it can appear Nudity#Evolution of hairlessness, hairless. There are two general types of skin: hairy and glabrous skin (hairless). The adjective List of medical roots, suffixes and prefixes#C, ''cutaneous'' literally means "of the skin" (from Latin ''cutis'', skin). Skin plays an important immunity (medical), immunity role in protecting the body against pathogens and excessive transepidermal water loss, water loss. Its other functions are Thermal insulation, insulation, thermoregulation, temperature regulation, sensation, synthesis of vitamin D, and the protection ...

Vestibular Bulbs
In female anatomy, the vestibular bulbs, bulbs of the vestibule or clitoral bulbs are two elongated masses of erectile tissue typically described as being situated on either side of the vaginal opening. They are united to each other in front by a narrow median band. Some research indicates that they do not surround the vaginal opening, and are more closely related to the clitoris than to the Vulval vestibule, vestibule. They constitute the Clitoris#Root, root of the clitoris along with the Crus of clitoris, crura. Structure Research indicates that the vestibular bulbs are more closely related to the clitoris than to the vestibule because of the similarity of the trabecular and erectile tissue within the clitoris and bulbs, and the absence of trabecular tissue in other genital organs, with the erectile tissue's trabecular nature allowing engorgement and expansion during sexual arousal. Ginger et al. state that although a number of texts report that they surround the vaginal opening, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embryo
An embryo ( ) is the initial stage of development for a multicellular organism. In organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization of the female egg cell by the male sperm cell. The resulting fusion of these two cells produces a single-celled zygote that undergoes many cell divisions that produce cells known as blastomeres. The blastomeres (4-cell stage) are arranged as a solid ball that when reaching a certain size, called a morula, (16-cell stage) takes in fluid to create a cavity called a blastocoel. The structure is then termed a blastula, or a blastocyst in mammals. The mammalian blastocyst hatches before implantating into the endometrial lining of the womb. Once implanted the embryo will continue its development through the next stages of gastrulation, neurulation, and organogenesis. Gastrulation is the formation of the three germ layers that will form all of the different parts of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genital Tubercle
A genital tubercle, phallic tubercle, or clitorophallic structure is a body of tissue present in the development of the reproductive system of amniotes. It forms in the ventral, caudal region of mammalian embryos of both sexes, and eventually develops into a primordial phallus. In the human fetus, the genital tubercle develops around week four of gestation, and by week nine, becomes recognizably either a clitoris or penis. This should not be confused with the sinus tubercle which is a proliferation of endoderm induced by paramesonephric ducts. Even after the phallus is developed (either a penile shaft or clitoral shaft), the term genital tubercle remains, but only as the terminal end of it, which develops into either the glans penis or the glans clitoridis. In the development of the male fetus, the two sides of the tubercle approach ventrally forming a hollow tube that encloses the male urethra. The two glans wings merge in the midline forming the septum glandis. In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ischiocavernosus Muscle
The ischiocavernosus muscle (erectores penis ''or'' erector clitoridis in older texts) is a muscle just below the surface of the perineum, present in both men and women. Structure It arises by tendinous and fleshy fibers from the inner surface of the tuberosity of the ischium, behind the crus penis; and from the inferior pubic rami and ischium on either side of the crus. From these points fleshy fibers succeed, and end in an aponeurosis which is inserted into the sides and under surface of the crus penis. Function In females, the ischiocavernosus muscle assists with clitoral erection. In males, it helps to stabilize the erect penis by compressing the crus penis and retarding the return of blood through the veins. Additional images File:Gray236.png, Right hip bone.

The clitoral crura (: clitoral crus) are two erectile tissue structures, which together form a "V" shape. ''Crus'' is a Latin word that means "leg". Each "leg" of the ''V'' converges on the clitoral body. At each divergent point is a corpus cavernosum. Together with the vestibular bulbs, they form the clitoral root. The crura are attached to the pubic arch, and are adjacent to the vestibular bulbs. The crura flank the urethra, urethral sponge, and vagina and extend back toward the pubis. Each clitoral crus connects to the rami of the pubis and the ischium The ischium (; : is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ischium
The ischium (; : ischia) is a paired bone forming the lower and back part of the hip bone. Situated below the ilium (bone), ilium and behind the pubis (bone), pubis, it is one of three regions whose fusion creates the coxal bone. The superior portion of this region forms approximately one-third of the acetabulum. Structure The ischium is made up of three parts–the body, the superior ramus and the inferior ramus. The body contains a prominent ischial spine, spine, which serves as the origin for the superior gemellus muscle. The indentation inferior to the spine is the lesser sciatic notch. Continuing down the posterior side, the ischial tuberosity is a thick, rough-surfaced prominence below the lesser sciatic notch. This is the portion ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
