Community, Family, and Reproductive Health - Male & Female Anatomy and Health Foundations Flashcards

Vocabulary practice flashcards covering male and female reproductive anatomy, physiological processes, and fundamental concepts of community, family, and reproductive health across the life course.

Scrotum

A pouch of skin, underlying fibrous and connective tissue, and smooth muscle located below the symphysis pubis that contains the testes, epididymides, and lower spermatic cords in two separate compartments.

Testes

The male gonads or primary reproductive organs, measuring approximately $4.5\,\text{cm}$ long, $2.5\,\text{cm}$ wide, and $3\,\text{cm}$ thick, responsible for producing sperm cells and testosterone.

Tunica Vaginalis

The double-membrane outer tissue covering of the testis, which develops from the abdominal and pelvic peritoneum.

Tunica Albuginea

The tough, fibrous tissue layer beneath the tunica vaginalis that extends internal partitions (septa) to divide the testicular tissue into lobules.

Tunica Vasculosa

The innermost protective covering of the testis, composed of delicate connective tissue and a vascular network of capillaries that supplies blood to testicular tissues.

Seminiferous Tubules

Coiled microscopic structures located within the testicular lobules ($1\text{--}4$ per lobule) that serve as the direct site of sperm production.

Leydig Cells

Interstitial cells located between the seminiferous tubules that produce testosterone, particularly after puberty.

Spermatogenesis

The process of sperm development and maturation occurring within the seminiferous tubules of the testes.

Cryptorchidism

A clinical condition defined by the failure of one or both testes to descend into the scrotum during fetal development.

Orchiopexy

The surgical procedure performed in infancy (ideally within the first $12\text{--}18\text{ months}$ of life) to correct cryptorchidism.

Spermatic Cord

A paired structure passing through the inguinal canal to suspend the testis in the scrotum, containing the vas deferens, testicular artery, testicular veins, lymphatic vessels, and nerves.

Sperm Cell Structure

A mature male gamete consisting of a head (containing nucleus, DNA, and enzymes), a midpiece (containing mitochondria for energy), and a tail/flagellum (for motility).

Epididymis

A long, highly coiled duct located along the posterior surface of each testis divided into a head, body, and tail, responsible for sperm maturation, storage, and transport over approximately $12\text{--}16\text{ days}$.

Ductus Deferens

Also known as the vas deferens, a muscular tube continuing from the tail of the epididymis through the spermatic cord into the pelvic cavity to propel sperm toward the ejaculatory duct.

Vasectomy

A surgical method of contraception that prevents sperm transport by cutting or sealing the ductus deferens.

Ejaculatory Duct

A short tube formed by the union of the duct of the seminal vesicle and the terminal part of the vas deferens that passes through the prostate to open into the prostatic urethra.

Male Urethra Parts

The $20\,\text{cm}$ long male urogenital passage divided into three sections: the prostatic urethra, the membranous urethra (shortest/narrowest), and the spongy or penile urethra (longest).

Hypospadias

A congenital abnormality of the male reproductive tract in which the urethral opening develops on the underside of the penis.

Seminal Vesicles

A pair of sac-like accessory glands behind the urinary bladder that produce fluid rich in fructose to nourish sperm and contribute to semen volume.

Prostate Gland

A single walnut-sized accessory gland located below the bladder around the prostatic urethra that secretes prostatic fluid to support sperm function and motility.

Bulbourethral Glands

Also known as Cowper's glands, paired small accessory glands near the membranous urethra that secrete a clear, alkaline mucus prior to ejaculation to lubricate and neutralize urethral acidity.

Community Health

The health status of a defined group of people and the private, public, and community actions and conditions aimed at promoting, protecting, and preserving their health.

Public Health

The field of health science focusing on population health at local, state, national, or global levels through health policy, surveillance, prevention, and population-wide interventions.

Community Participation

The active involvement of community members in identifying health problems, setting priorities, planning, implementing, and evaluating health programs.

Family Health

A state of health considering individual family members and the family as a unified social and healthcare unit within its environment.

Reproductive Health

A state of complete physical, mental, and social well-being—and not merely the absence of disease or infirmity—in all matters relating to the reproductive system, its functions, and processes.

Vulva

The collective name for the female external genital organs, including the mons pubis, labia majora, labia minora, clitoris, vestibule, Bartholin's glands, and bulbs of the vestibule.

Mons Pubis

A rounded pad of fatty tissue overlying the pubic symphysis that provides cushioning and becomes covered with pubic hair after puberty.

Labia Majora

Two large outer skin folds containing connective tissue, fat, sweat, and sebaceous glands that extend along either side of the vulva for protection.

Labia Minora

Two small, hairless inner folds of skin lacking fat that surround the vestibule and are richly supplied with blood vessels and sensory nerves.

Clitoris

A small, highly sensitive erectile organ located at the anterior junction of the labia minora above the urethral opening, primarily responsible for female sexual arousal.

Vestibule

The anatomical space enclosed by the labia minora that houses the external urethral orifice, vaginal orifice, and associated gland openings.

Skene's Glands

Paraurethral glands whose ducts open on either side of the urethral orifice to produce lubricating secretions.

Bartholin's Glands

Also called greater vestibular glands, paired small glands located near the vaginal opening that secrete lubricating mucus into the vestibule.

Hymen

A thin fold of mucosal tissue surrounding or partially covering the vaginal orifice, whose elasticity and shape vary widely among individuals.

Imperforate Hymen

A congenital condition where the hymen completely obstructs the vaginal opening.

Bulbs of the Vestibule

Paired masses of erectile tissue situated on either side of the vaginal opening that become engorged with blood during sexual arousal.

Vagina

A distensible fibromuscular tube measuring approximately $7\text{--}10\,\text{cm}$ long, extending upwards and backwards from the vestibule to the cervix.

Posterior Fornix

The largest and deepest recess formed at the upper vaginal vault where the cervix projects into the vagina.

Vaginal Douching

The unrecommended practice of flushing the inside of the vagina with fluid, which can alter acidic pH, disrupt normal microflora, and increase infection risks.

Uterus

A hollow, pear-shaped muscular organ in the true pelvis measuring approximately $7.5\,\text{cm}$ long, $5\,\text{cm}$ wide, and $2.5\,\text{cm}$ thick in a non-pregnant adult.

Anteversion

The physiological position where the entire uterus tilts forward relative to the long axis of the vagina, toward the urinary bladder.

Anteflexion

The anatomical bend of the uterus where the body flexes forward relative to the cervix.

Endometrium

The innermost mucosal layer of the uterine body composed of the stratum basalis and the cyclical stratum functionalis, serving as the site for embryo implantation.

Myometrium

The thick middle muscular layer of the uterine wall composed of interlacing smooth muscle fibers that produce menstrual and labor contractions.

Perimetrium

The outer serous covering of much of the uterus, formed by visceral peritoneum continuous with the broad ligaments.

Cervical Canal Openings

The passage within the cervix bounded by the internal os (opening superiorly into the uterine cavity) and external os (opening inferiorly into the vagina).

Transformation Zone

The cervical region at the squamocolumnar junction where mucus-secreting columnar epithelium is physiological transformed into stratified squamous epithelium.

Transverse Cervical Ligaments

Also called cardinal or Mackenrodt's ligaments, major structural supports extending laterally from the cervix and upper vagina to the lateral pelvic walls.

Round Ligaments

Uterine ligaments extending from the cornua through the inguinal canals to the labia majora that help maintain the anteverted position of the uterus.

Uterine Tube Regions

The four anatomical segments of the $10\,\text{cm}$ uterine tube: the intramural/interstitial part (narrowest), isthmus, ampulla (widest, fertilization site), and infundibulum (funnel-shaped with fimbriae).

Mesosalpinx

The specific portion of the broad ligament that encloses and supports the uterine tube.
