Ch. 14 The Male Reproductive System Flashcards
Androgen
any hormone that produces male characteristics
Bulbourethral Gland
a small gland beside the urethea below the prostate that secretes part of the seminal fluid. Also called the Cowper gland
Circumcision
Surgical removal of the end of the prepuce
Coitus
Sexual Intercourse
Ductus Deferens
The duct that conveys spermatozoa from the epididymis to the ejaculatory duct. Also called vas deferens
Ejaculation
ejection of semen from the male urethra
Ejaculatory Duct
the duct formed by union of the ductus deferens and the duct of the seminal vesicle. It carries spermatozoa and seminal fluid into the urethra
Epididymis
a coiled tube on the surface of the testis that stores sperm until ejaculation
Erection
the stiffening or hardening of the penis or the clitoris, usually because of sexual excitement
Follicle-Stimulating Hormone (FSH)
a hormone secreted by the anterior pituitary that acts on the gonads. In males, FSH stimulates Sertoli cells that promote cell development
Gamate
a mature reproductive cell, the spermatozoon on the male and the ovum in the female
Glans Penis
the bulbous end of the penis
Gonad
a sex gland; testis or ovary
Inguinal Canal
the channel through which the testis descends into the scrotum in the male
Interstitial Cells
Cells located between the seminiferous tubules of the testes that produce hormones mainly testosterone
Luteinizing Hormone (LH)
a hormone secreted by the anterior pituitary that acts on the gonads. In males, it stimulates the interstitial cells to produce testosterone
Meiosis
the type of cell division that creates gametes; it results in cells with 23 chromosomes half the number found in other body cells
Penis
the male organ of copulation and urination
Pituitary Gland
an endocrine gland at the base of the brain
Prepuce
the fold of skin over the glans penis; the foreskin
Prostate Gland
a gland that surrounds the urethra below the bladder in males and contributes secretions to the semen
Scrotum
a double pouch that contains the testes
Seminal Vesicle
a sac-like gland behind the bladder that contributes secretions to the sperm
Sertoli Cell
Cell in a seminiferous tubule that aids in the development of spermatozoa; sustentacular cell
Spermatic Cord
cord attached to the testis that contains the ductus deferens, blood vessels, and nerves enclosed within a fibrous sheath
Spermatozoon
mature male sex cells
testosterone
the main male sex hormone
urethra
the duct that carries urine out of the body and also transport semen in the male
Vas Deferens
the duct that conveys spermatozoa from the epididymis to the ejaculatory duct. Also called the ductus deferens
test/o
testis, testicle
orchi/o, orchid/o
testis
osche/o
scrotum
semin
semen
sperm/i, spermat/o
semen, spermatozoa
