Human Reproductive Systems Quiz

The human organ system responsible for producing and fertilizing gametes (sperm or eggs) and carrying a fetus in females.

A haploid cell that combines with another haploid gamete during fertilization, forming a zygote.

Organs in the reproductive system that produce gametes and sex hormones.

Endocrine hormones that control sexual organ development, puberty, and reproduction.

A pouch-like sac of skin that holds the testes, keeping them at a temperature slightly below body temperature for sperm production.

The process of sperm production.

A single diploid cell formed by the fusion of two gametes during fertilization.

The scrotum's muscles adjust the testicles' position to regulate temperature, keeping them at the optimal temperature for sperm production.

The process of sperm creation in the seminiferous tubules, transforming immature sperm into mature sperm.

These tubules within the testes are the site where sperm are produced.

Support and nourish developing sperm cells, and help create a blood-testis barrier.

Hormone that stimulates Sertoli cells to produce proteins like androgen-binding protein, necessary for sperm production.

Produce testosterone, crucial for male characteristics and sperm development.

The key hormone that drives male sexual characteristics and supports sperm production.

Stimulates Leydig cells to produce testosterone.

Fibrous tissue capsule surrounding the testes.

Partitions dividing the testes into lobules.

Cone-shaped structures within the testes housing seminiferous tubules.

Pair of glands that secrete an alkaline fluid into the urethra, important for pre-ejaculate.

Prostatic, Membranous, and Spongy (Penile) sections of the tube. Passageway for urine and semen.

Male organ of copulation with three erectile tissues (Corpora Cavernosa & Corpus Spongiosum).

Two of the three cylindrical masses of erectile tissue in the penis.

A cylindrical mass of erectile tissue in the penis that encloses the penile urethra.

Outer, dense portion of the ovary containing follicles.

Inner, loose portion of the ovary containing blood vessels and nerves.

Temporary endocrine structure in the ovary that produces progesterone and some estrogen.

Reproductive cells (gametes) responsible for sexual reproduction.

Support and nourish developing sperm in the seminiferous tubules.

Smooth muscle cells in the seminiferous tubules that aid in sperm movement.

Short tubes connecting seminiferous tubules and rete testis; simple cuboidal epithelium with Sertoli cells.

Network of tubules that collect sperm from seminiferous tubules before entering efferent ducts; simple cuboidal epithelium.

Tubules facilitating sperm transport from rete testis to epididymis; alternating simple cuboidal and columnar.

Comma-shaped structure that stores and matures sperm; pseudostratified columnar epithelium.

Columnar cells with stereocilia in the epididymis.

Undifferentiated cells found in the epididymis.

Tube conveying sperm from epididymis to ejaculatory duct; pseudostratified and thick muscularis.

Structure containing blood vessels, nerves and ductus deferens.

Canal formed by seminal vesicle and ductus deferens; opening into urethra.

Glands producing seminal fluid, containing fructose and prostaglandins.

Walnut-shaped gland at bladder neck, secreting components to seminal fluid.

Oviducts; tubes that transport eggs from the ovaries to the uterus. They have distinct regions: Infundibulum, Ampulla, Isthmus, and Uterine part

The funnel-shaped, open end of the uterine tube, catching the egg.

The widest part of the uterine tube, often the site of fertilization.

The narrow section of the uterine tube connecting to the uterus.

Pear-shaped organ with muscular walls; site of fetal development.

The part of the uterine tube that is embedded within the uterine wall.

The top, rounded portion of the uterus.

Larger central part of the uterus.

Narrowing section connecting the body and cervix of the uterus.

Neck-like portion of the uterus that opens into the vagina.

Outermost layer of the uterus, the serosa.

The muscular middle layer of the uterus.

Inner lining of the uterus; site of implantation and sloughs off during menstruation.

Hormone that stimulates uterine contractions during labor and milk ejection.

Female organ for sexual intercourse and childbirth.

Glands that secrete mucus for lubrication during sexual arousal.

Female external reproductive organs; Includes vestibule, labia minora, majora, and clitoris

Highly sensitive erectile tissue; comprised of corpora cavernosa and glans clitoris

Mammary gland, responsible for milk production; composed of ducts, alveoli, and suspensory ligaments.

Milk-carrying ducts in the breast.

Cells that surround alveoli in the breasts and contract to express milk.

Connective tissues that support the breasts
