Chapter 3 & 4 Males and Females Body Parts Flashcards
Mons Veneris
Pubic symphysis
The frontmost component of the vulva: a pad of fatty tissue covered by skin and pubic hair.
The junction of the left and right pubic bones, the frontmost elements of the pelvic skeleton.
Pubic Hair
serves to protect vagina from bacteria & to “wick & volatilize” viginal odors
Labia Majora
the outer lips: 2 folds of skin that run down from the monds on either side of the vulva.
- Composed of fatty tissue
- hair on outer sides
- Erotically sensitive, specially on the inner, hairless sides of the labia.
Labia Minora
the inner lips: hairless, loose folds of skin located between the labia majora and immediately flanking the vestibule.
Clitoral Hood
A loose fold of skin that covers the clitoris.
the labia minora meet at the front, forming the clitorial hood, and at the back
Vestibule
Fourchette
The potential space between the left and the right labia minora. It inclucles the clitoris, urethral opening, & vaginal opening.
The fourchette - place where labia minor meet behind the vestibule
Clitoris
Clitorial Glans
The erectile organ in females, whose external portion is located at the junction of the labia minra, just in front of the vestibule.
Small, erectile, & highly sensitive knob of tissue positioned at the front of the vestibule.
Corpora Cavernosa (2)
contain the clitoriis’ erectile tissue. It can extend back to the pelvic floor. The erectile tissue withing the glans consist of a single corpus spongiosum.
Corpus Spongiosum
A single midline erectile structure. In both sexes it fills the glans.
Stegma
A whitish, greast secreation that builds up under the prepuce of the penis or clitoris.
Crura
internal extensions of the clitoris. 7cm long; wrap the urethra. internal extension of the corpus cavernosum.
Vestibular Bulbs
curved masses of erectile tissue that surround the vestibule & underlie the labia minora = it helps for elevation, lengthen, and stiffen of the vagina in arousal.
Ischiocavernosus Muscle
Surround each crus; contraction of these during arousal elevates the clitoral shaft & glans, causing the glans to disappear under the clitoral hood.
Bulbospongiosus Muscle
forms a sling around the clitoral shaft and surrounds the vaginal opening; contraction of this muscle tightens vaginal opening & increases clitoral erection, and may also help increase the erotic sensations of vaginal penetration by transferring mechanical excitation to the clitoris.
Viginal Opening
Introitus - occupies rear portion of the vestibule; at birth, generally covered by an imcomplete membranous flod of skin called the hymen.
Urethral Opening
located between the vaginla opening and the clitoris. It conveys urine, but it can also ejaculate from it during sexual climax.
Bartholin’s Glands
Lie on either side of the vaginal opening, just inside the labia minora. They secrete a few drops of fluid prior to orgasm. It is possible that these secreations help neuutralize the normally acidic environment of the vagina.
Pelvic Floor
Pubococcygeus Muscle
A muscular sling that underlies and supports the pelvic bone.
a pair of muscles in the pelvic floor that form a sling aorund the vagina. The stiffeness of this muscle during sex, increases pleasure. It prevents urinary and fecal leakage, and possibly help keep semen in the vagina.
Vagina
Potential space; collapsed tube
Forms the birth canal
A muscular tube extending 8 to 10 cm from the pathway taken by gametes or the conceptus.
Reproductive Track
The internal anatomical structures in either sex that form the pathway taken by gametes or the conceptus.
It serves for transport of the male’s sperm and the female’s eggs (ova), as well as fertilization, pregnancy, and passage of the fetus during childbirth.
Procedure where the are between the vaginal opening and the anus Perineum is cut to make more room for the fetus to come out
Episiotomy
Circumferential wrinkles in the inner surface of the vagina
Rugae
Grafenberg Spot
G-spot—an area of heightened sensitivity on the front wall of the vagina; the trigger point for the controversial vaginal orgasm
Only a minority of women claim to have a G-spot. An orgasm is stronger if produce by stimulation of the G-Spot
There are many theories to what structure in the vagina is responsible for a G-spot erection. Even though there are many posibilities there is one that is the most likely.
Glands situated next to the urethra, thought to be equivalent to the larger prostate gland in males
The gland is also responsible for the ejaculation in females
Paraurethral (Skene’s) Glands
A circular muscle around an orifice whose contraction closes the orifice (in this case, the anus).
Sphincter
Uterus
The womb.
a pear-shaped region of the female reproductive tract through which sperm are transported and where the conceptus implants and develops.
Lowermost part of the uterus that opens into the vagina
Cervic
External and Internal Os
a constricted opening that connects the vagina to a canal that runs through the cervix
a second canal that connects the cervix to the uterus
The os posses glands that secreate mucus
The cavity of the uterus
Lumen
Three Layers of the walls of the uterus
Endometrium
Myometrium
Perimetrium
A layer of the uterus that has two functions-the transposrt of sperm up the reproductive track toward the site of fertilization, and the implantation and nourishment of an embry. Because of these two functions it changes over the menstrual cycle
Endometrium
Smooth Muscle
It is under control of the autonomic nervous system.
Involuntary contractions of the myometrium during labor play a vital role in the delivery of the fetus. Myometrical contractions are also thought to aid in the shedding and expulsing of the endometrial lining at menstruation
Conceptus
cluster of cells derived from a fertilized ovum, part of which becomes an embryo
This part of the body is located at top of the uterus.
Fertilization takes place here.
It is about 10cm long and has the width of two hair put together
The Fallopian Tubes or Oviducts
A fringe-like set of extensions at the end of the fallopian tubes
They brush the ovaries in order to sweep in released the ovum
Fimbria
