Bulbourethral Glands
Two Exocrine glands near the male urethra.
Ductus Deferens
Vas Deferens.
Cowper Glands
Bulbourethral Glands.
Ejection of sperm and fluid from the male urethra.
Ejaculatory Duct
Tube formed by the union of the vas deferens and the duct of the seminal vesicles, opening into the urethra at the prostate gland.
Epididymis (Plural Epididymides)
Tube located on top of each testis; it carries and stores the sperm cells before the enter the vas deferens.
Hair-like process on a sperm cell that makes it motile (able to move).
Fraternal Twins
Twins resulting from two separate, concurrent fertilizations.
Glans Penis
Sensitive tip of the penis.
Identical Twins
Twins resulting from the separation of one fertilized egg into two distinct embryos.
Interstitial Cells of the Testis
Cells that lie between the seminiferous tubules and produce the hormone testosterone. A pituitary gland hormone (LH) stimulates the interstitial cells to produce testosterone.
Parenchymal Tissue (parenchyma)
Tissue composed of the essential cells of any organ. In the testes, parenchymal tissue includes seminiferous tubules that produce sperm.
Area between the anus and scrotum in the male.
Prepuce (foreskin)
Skin covering the tip of the penis.
Prostate Gland
Gland at the base of the urinary bladder that secretes a fluid into the urethra during ejaculation.
External sac (double pouch) that contains the testes.
Spermatozoa and fluid (prostatic and other glandular secretions).
Seminal Vesicles
Glands that secrete a fluid into the Vas Deferens.
Seminiferous Tubules
Narrow, coiled tubules in the testes that produce sperm.
Spermatozoon (Plural: Spermatozoa)
Sperm Cell.
Any procedure rendering an individual incapable of reproduction; Vasectomy and Salpingectomy are examples.
Supportive, connective tissue of an organ.
Testis (Plural: Testes)
Male Gonad that produces Spermatozoa and the hormone testosterone; Testicle.
Hormone secreted by the interstitial tissue of the testes; responsible for male sex characterisitics.
Vas Deferens
Narrow tube (one on each side) that carries sperm from the epididymis into the body and toward the urethra.
