Round Ligament Of Uterus
The round ligament of the uterus is a ligament that connects the uterus to the labia majora. It originates at the junction of the uterus and uterine tube. It passes through the inguinal canal to insert at the labium majus. The two round ligaments of uterus develop from the gubernaculum; they are the female homologue of the male gubernaculum testis. Structure The round ligament of the uterus originates at the uterine horns, in the parametrium. The round ligament exits the pelvis via the deep inguinal ring. It passes through the inguinal canal to reach the labium majus, inserting into the fibro-fatty substance of the labium majus. Blood supply The round ligament is supplied by the artery of the round ligament of uterus, also known as ''Sampson's artery''. Development The round ligament develops from the gubernaculum which attaches the gonad to the labioscrotal swellings in the embryo. Function The round ligament of uterus acts to hold the uterus anterior-ward to in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pelvis
The pelvis (: pelves or pelvises) is the lower part of an Anatomy, anatomical Trunk (anatomy), trunk, between the human abdomen, abdomen and the thighs (sometimes also called pelvic region), together with its embedded skeleton (sometimes also called bony pelvis or pelvic skeleton). The pelvic region of the trunk includes the bony pelvis, the pelvic cavity (the space enclosed by the bony pelvis), the pelvic floor, below the pelvic cavity, and the perineum, below the pelvic floor. The pelvic skeleton is formed in the area of the back, by the sacrum and the coccyx and anteriorly and to the left and right sides, by a pair of hip bones. The two hip bones connect the spine with the lower limbs. They are attached to the sacrum posteriorly, connected to each other anteriorly, and joined with the two femurs at the hip joints. The gap enclosed by the bony pelvis, called the pelvic cavity, is the section of the body underneath the abdomen and mainly consists of the reproductive organs and ...

Deep Inguinal Ring
The inguinal canal is a passage in the anterior abdominal wall on each side of the body (one on each side of the midline), which in males, convey the spermatic cords and in females, the round ligament of the uterus. The inguinal canals are larger and more prominent in males. Structure The inguinal canals are situated just above the medial half of the inguinal ligament. The canals are approximately 4 to 6 cm long, angled anteroinferiorly and medially. In males, its diameter is normally 2 cm (±1 cm in standard deviation) at the deep inguinal ring.The diameter has been estimated to be ±2.2cm ±1.08cm in Africans, and 2.1 cm ±0.41cm in Europeans. A first-order approximation is to visualize each canal as a cylinder. Walls To help define the boundaries, these canals are often further approximated as boxes with six sides. Not including the two rings, the remaining four sides are usually called the "anterior wall", "inferior wall ("floor")", "superior wall ("roof")", and "poste ...

Pregnancy
Pregnancy is the time during which one or more offspring gestation, gestates inside a woman's uterus. A multiple birth, multiple pregnancy involves more than one offspring, such as with twins. Conception (biology), Conception usually occurs following sexual intercourse, vaginal intercourse, but can also occur through assisted reproductive technology procedures. A pregnancy may end in a Live birth (human), live birth, a miscarriage, an Abortion#Induced, induced abortion, or a stillbirth. Childbirth typically occurs around 40 weeks from the start of the Menstruation#Onset and frequency, last menstrual period (LMP), a span known as the Gestational age (obstetrics), ''gestational age''; this is just over nine months. Counting by Human fertilization#Fertilization age, ''fertilization age'', the length is about 38 weeks. Implantation (embryology), Implantation occurs on average 8–9 days after Human fertilization, fertilization. An ''embryo'' is the term for the deve ...

Cardinal Ligament
The cardinal ligament (also transverse cervical ligament, lateral cervical ligament, or Mackenrodt's ligament) is a major ligament of the uterus formed as a thickening of connective tissue of the base of the broad ligament of the uterus. It extends laterally (on either side) from the cervix and vaginal fornix to attach onto the lateral wall of the pelvis. The female ureter, uterine artery, and inferior hypogastric (nervous) plexus course within the cardinal ligament. The cardinal ligament supports the uterus. Structure The cardinal ligament is a paired structure on the lateral side of the uterus. It originates from the lateral part of the cervix. Attachments It attaches the cervix to the lateral pelvic wall by its attachment to the obturator fascia of the obturator internus muscle. It attaches to the uterosacral ligament. Relations It is continuous externally with the fibrous tissue surrounding the pelvic blood vessels. Function The cardinal ligament supports the uter ...

Recumbence
Lyingalso called recumbency, prostration, or decubitus in medicine ()is a type of human position in which the body is more or less horizontal and supported along its length by the surface underneath. Lying is the most common position while being immobilized (e.g. in bedrest), while sleeping, or while being struck by injury or disease. Positions When lying, the body may assume a great variety of shapes and positions. The following are the basic recognized ones. * Supine: lying on the back on the ground with the face up. * Prone: lying on the chest with the face down ("lying down" or "going prone"). See also "Prostration". * Lying on either side, with the body straight or bent/curled forward or backward. ** The fetal position is lying or sitting curled, with limbs close to the torso and the head close to the knees. ** The recovery position (coma position), one of a series of variations on a lateral recumbent or three-quarters prone position of the body, into which an unconsci ...

Anteversion
Standard anatomical terms of location are used to describe unambiguously the anatomy of humans and other animals. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on. As part of defining and describing terms, the body is described through the use of anatomical planes and axes. The meaning of terms that are used can change depending on whether a vertebrate is a biped or a quadruped, due to the difference in the neuraxis, or if an invertebrate is a non-bilaterian. A non-bilaterian has no anterior or posterior surface for example but can still have a descriptor used such as proximal or distal in relation to a body part that is nearest to, or furthest from its middle. International organisations have determined vocabularies that are often used as standards for subdisciplines of anatomy. For example, ''Terminologia Anato ...

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] |
Labioscrotal Swellings
The labioscrotal swellings (genital swellings or labioscrotal folds) are paired structures in the mammalian embryo that represent the final stage of development of the caudal end of the external genitals before sexual differentiation. In humans, the two swellings merge: * In the ''female'', they become the posterior labial commissure. The sides of the genital tubercle grow backward as the genital swellings, which ultimately form the labia majora; the tubercle itself becomes the mons pubis. * In the ''male'', they become the scrotum In most terrestrial mammals, the scrotum (: scrotums or scrota; possibly from Latin ''scortum'', meaning "hide" or "skin") or scrotal sac is a part of the external male genitalia located at the base of the penis. It consists of a sac of skin .... References External links "Development of Male External Genitalia", at mcgill.caDiagram at mhhe.com* * {{Authority control Embryology of urogenital system ...

Gonad
A gonad, sex gland, or reproductive gland is a Heterocrine gland, mixed gland and sex organ that produces the gametes and sex hormones of an organism. Female reproductive cells are egg cells, and male reproductive cells are sperm. The male gonad, the testicle, produces sperm in the form of Spermatozoon, spermatozoa. The female gonad, the ovary, produces egg cells. Both of these gametes are haploid cells. Some hermaphroditic animals (and some humanssee Ovotesticular syndrome) have a type of gonad called an ovotestis. Evolution It is hard to find a common origin for gonads, but gonads most likely evolved independently several times. Regulation The gonads are controlled by luteinizing hormone (LH) and follicle-stimulating hormone (FSH), produced and secreted by gonadotropic cell, gonadotropes or gonadotrophins in the anterior pituitary gland. This secretion is regulated by gonadotropin-releasing hormone (GnRH) produced in the hypothalamus. Development The gonads develop f ...

Artery Of Round Ligament Of Uterus
The artery of the round ligament of the uterus, also known as Sampson's artery, is a branch of the inferior epigastric artery. It runs under, and supplies, the round ligament of the uterus. It constitutes an anastomosis of the uterine artery and ovarian artery. It was originally named after John A. Sampson (1873–1946), an American gynecologist who studied endometriosis. Clinical significance It is considered an insignificant artery that is dissected during hysterectomies. It can be the source of hemoperitoneum Hemoperitoneum (also haemoperitoneum, sometimes also hematoperitoneum) is the presence of blood in the peritoneal cavity. The blood accumulates in the space between the inner lining of the abdominal wall and the internal abdominal organs.

Parametrium
The parametrium is the fibrous and fatty connective tissue that surrounds the uterus. This tissue separates the supravaginal portion of the cervix from the bladder. The parametrium lies in front of the cervix and extends laterally between the layers of the broad ligaments. It connects the uterus to other tissues in the pelvis. It is different from the perimetrium, which is the outermost layer of the uterus. The uterine artery and ovarian ligament are located in the parametrium. An associated form of pelvic inflammatory disease Pelvic inflammatory disease (PID), also known as pelvic inflammatory disorder, is an infection of the upper part of the female reproductive system, mainly the uterus, fallopian tubes, and ovaries, and inside of the pelvis.
