Reproductive System
Male Reproductive System
Definition of Terms
Prostate
The prostate is a gland in men that helps to make semen, the fluid that contains sperm. The prostate surrounds the tube that transports urine away from the bladder and out of the body. A young man’s prostate is about the size of a walnut. It slowly grows larger with age.
Seminal vesicle
The seminal gland, as well known as the seminal vesicle, holds the liquid that mixes with sperm to form semen. Semen is made up of fluid from the epididymis, seminal vesicle, prostate gland, and vas deferens. The fluids help the sperm swim towards the egg and keep the sperm nourished during the traveling process.
Rectovesucal pouch
This is a sac between the rectum and the urinary bladder in males that is formed by a folding of the peritoneum.Its bottom is slightly below the level of the upper ends of the vesiculae seminales—i. e., about 7.5 cm. from the orifice of the anus. A membranous partition known as the Rectoprostatic fascia (Denonvillier’s fascia) is situated at the lowest part of the rectovesical pouch.
Rectum
The rectum is the concluding part of the large intestine that terminates in the anus. The average length of the human rectum may range between 10 and 12 cm. It gets dilated near the anus, where it forms the rectal ampulla. Its major role is to act as a temporary storehouse for feces.
Anus
The anus is the opening where the gastrointestinal tract ends and exits the body. The anus starts at the bottom of the rectum, the last portion of the colon (large intestine). The anorectal line separates the anus from the rectum. Tough tissue known as fascia surrounds the anus and attaches it to the structures close by.
Bulb of penis
The bulb of penis means the bottom portion of the penis. It is as well referred to as the base of the penis. The bulb is made up of a large bundle of tissue. The tissue mass expands from the corpus spongiosum. The bulb is situated above the scrotum, which is the swelling that contains the testicles.
Scrotum
The scrotum is a part of the external male genitalia situated behind and under the penis. It is the small muscular sac that contains and protects the testicles, blood vessels, and part of the spermatic cord. It is divided interiorly into two sections by a septum, and each section contains a testicle. The scrotum protects the testicles from temperature changes
Testicle
Testicles, or testes, produce male hormones and sperm. They are two egg-shaped organs inside the scrotum, the loose sac of skin behind the penis. It’s easy to injure your testicles due to the fact that they are not protected by bones or muscles. Men and boys should wear athletic supporters when they play sports.
Epididymus
The epididymis is a long, coiled tube that stores sperm and transports it from the testes. It appears as a curved structure on the posterior margin of each testis, and is made up of three sections known as the head, body, and tail. Though it looks superficially like the testes, the epididymis is smaller, and the tubes are larger and less densely packed.
Fore skin
The foreskin represents at least a third of the penile skin and protects the glans from abrasion and contact with clothes. The foreskin as well increases sexual pleasure by sliding up and down on the shaft, stimulating the glans by alternately covering and exposing it. This can occur during masturbation or intercourse.
Glans
The glans penis can mainly be described as the rounded head of a penis. Located in the middle of the glans penis is the opening of the urethra. At birth, the glans of the penis is attached to an area of skin called the foreskin. Over time, this foreskin will begin to break up from the glans, until the skin is able to full retract.
Penis
The human penis is an external male sexual organ. It is a reproductive, intermittent organ that additionally serves as the urinal duct. A penis is the primary sexual organ that male and hermaphrodite animals use to inseminate sexually receptive mates during sexual intercourse. A penis can be fractured if it is forcefully bent when engorged.
Urethra
The urethra is the tube through which urine passes out of the body. In men, it’s a long tube that runs through the penis. It also carries semen in men. In women, it’s short and is just above the vagina. Urethral problems may happen due to aging, illness, or injury.
Urinary bladder
The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is produced in the kidneys, and travels down two tubes known as ureters to the bladder. The bladder stores urine, permitting urination to be infrequent and voluntary.
Female Reproductive System
Definition of Terms
Female Reproductive System
The female reproductive system allows for the nurturing of a fertilized egg to develop into a fetus. The external female genitals consist of numerous parts, including the vaginal opening, clitoris, urethra, labia minora, and labia majora. Although a woman’s external genitals are normally referred to as the “vagina,” the vagina in reality is one of the many parts that form that section of a woman’s body.
Fallopian tube
The uterine tube (Fallopian tube) transports an egg from the ovary to the uterus. Unless a biological abnormality, surgery, or ectopic pregnancy resulted to the loss of a tube, women ought to have two uterine tubes in their bodies. A few women may suffer from a tubal or ectopic pregnancy that puts their fallopian tube and their lives in danger.
Ovary
The ovary is a ductless reproductive gland in which the female reproductive cells are produced. It is one of the paired sexual gonads in females held by a membrane beside the uterus on each side of the lower abdomen. It is required in reproduction since it is responsible for producing the female reproductive cells or ova.
Urinary bladder
The urinary bladder is a muscular sac in the pelvis, just above and behind the pubic bone. When empty, the bladder is about the size and shape of a pear. Urine is produced in the kidneys, and travels down two tubes known as ureters to the bladder. The bladder stores urine, permitting urination to be infrequent and voluntary.
Symphysis pubis
The pubic symphysis is a midline or secondary cartilaginous joint situated between the left and right pubic bones of the median plane. More specifically, it is situated superior to any external genitalia and anterior to the bladder. It can be found above the penis in males and above the vulva in females.
Mons veneris
The mons pubis is also known as mons, mons veneris, or pubic mound. It is the fat pad covering on the pubic bone which divides to form labia majora. The main functions of mons pubis are to cussion and protection to the pubic and also protect the bones and tissues lying beneath.
Clitoris
The clitoris is the key to all female orgasms and clitoris is the human female’s most erogenous zone, often known as the ‘female penis’ due to the fact that it is similar in form to the male penis. It is possible for all women to orgasm if the female erectile organs are effectively stimulated.
Orifice of urethra
The external urethral orifice (urinary meatus) is the external opening of the urethra, from which urine is ejected during urination. It is placed about 2.5 cm behind the glans clitoridis and immediately in front of that of the vagina. The internal urethral orifice is the opening of the urinary bladder into the urethra. It is placed at the apex of the trigonum vesicae.
Vagina
The vagina is an elastic, muscular tube that connects the cervix of the uterus to the vulva and exterior of the body. The vagina is located in the pelvic body cavity posterior to the urinary bladder and anterior to the rectum. It measures about 3 inches in length and less than 1 inch in diameter but stretches during sexual intercourse and childbirth.
Anus
The anus is the opening where the gastrointestinal tract ends and exits the body. The anus starts at the bottom of the rectum, the last portion of the colon (large intestine). The anorectal line separates the anus from the rectum. Tough tissue known as fascia surrounds the anus and attaches it to the structures close by.
Cervix
The cervix is the lower part of the uterus also known as the womb and is the place where a baby grows during pregnancy. The cervix has a small opening that expands during childbirth. It as well allows menstrual blood to leave a woman’s body
Rectum
The rectum is the concluding part of the large intestine that terminates in the anus. The average length of the human rectum may range between 10 and 12 cm. It gets dilated near the anus, where it forms the rectal ampulla. Its main role is to act as a temporary storehouse for feces.
Vaginal fornix
The vaginal fornix is the anterior (front) and posterior (back) recesses into which the upper vagina is divided. These vault-like recesses are created by protrusion of the cervix into the vagina. The fornix uteri is as well known as the fornix vaginae (or the vaginal fornices) and the uterine fornices.
Sigmoid
In human anatomy, the lower colon, the lower portion of the large bowel is known as sigmoid. Sigmoid is short for sigmoid colon. It is gotten from the Greek letter sigma, which is shaped like a C. Sigmoid also means curved in two directions like the letter S. For example, a sigmoid curve is an S-shaped curve.
Uterus
The uterus is a female reproductive organ situated between the bladder and the rectum, in the pelvic area. The uterus has three layers: the inner lining (endometrium); the middle muscular layer (myometrium); and the outer layer (perimetrium). The uterus is linked to the fallopian tubes, the cervix and through the cervix to the vagina.
Sacrum
The sacrum is a large wedge shaped vertebra at the inferior end of the spine. It forms the solid base of the spinal column where it intersects with the hip bones to form the pelvis. The sacrum is a very strong bone that supports the weight of the upper body as it is spread across the pelvis and into the legs.
