Chp 12 Med Term – Flashcards

The medical specialty that studies the anatomy and physiology of the male genitourinary system and uses diagnostic tests, medical and surgical procedures, and drugs to treat male reproductive diseases

shares the urethra with the urinary system and is also known as the urogenital system

Scrotum Testes Epididymides Penis Urethra

Vas deferens Seminal vesicles Ejaculatory ducts Prostate gland Bulbourethral glands

to secrete the male hormones, develop male secondary sexual characteristics, produce spermatozoa, and release spermatozoa.

Soft pouch of skin behind the penis and in front of the legs Few degrees cooler than the core body temperature Muscles in wall of the scrotum contract or relax to move the scrotum closer to, or farther away from, the body to adjust to temperature changes.

the area between the anus and the scrotum

The scrotum contains the testes or testicles. Egg-shaped glands about 2 inches in length Testes are the gonads, or sex glands. Function as part of the male genitourinary system and the endocrine system Contain the seminiferous tubules that produce spermatozoa, or sperm Act as endocrine glands; secrete the hormone testosterone

A long, tightly coiled tube (over 20 feet) that is attached to the outer wall of each testis. Within the epididymis, the head of each spermatozoon is given a cap-like layer of enzymes that helps it penetrate and fertilize the ovum of the female. Destroys defective spermatozoa

is a long tube that receives spermatozoa from the epididymis goes behind the urinary bladder, where it merges with a seminal vesicle.

can be stored in the vas deferens for several months in an inactive state.

produce seminal fluid, which makes up most of the volume of semen.

is a large collecting duct that holds spermatozoa and seminal fluid. enters the prostate gland, then joins the urethra within the prostate gland.

A donut-shaped gland at the base of the bladder that produces prostatic fluid.

contains an antibiotic substance that kills bacteria and also contains acid phosphatase, an enzyme that breaks the deposit of semen apart and releases the spermatozoa in the woman's vagina

Small, bulblike glands about the size of peas, located on either side of the urethra just below the prostate gland Produce thick mucus that makes up some of the volume of the semen Mucus helps spermatozoa survive by neutralizing the acidity of any urine remaining in the urethra at the time of ejaculation and neutralizing the normally acidic environment of the female vagina

Functions as an organ of the male genitourinary system and the urinary system. In uncircumcised males, the urethral meatus is covered by the prepuce, or foreskin, of the penis. Three columns of erectile tissue fill with blood during sexual arousal, causing the penis to become firm and erect

At the onset of puberty, the anterior pituitary gland in the brain begins to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH) to stimulate the testes. FSH causes the seminiferous tubes to enlarge and stimulates spermatocytes in the testes to begin dividing. LH stimulates the interstitial cells to begin to secrete testosterone.

causes the male sexual characteristics to develop: Enlargement of the external genitalia Development of large muscles Deepening of the voice Growth of body hair on the face, chest, axillae, and genital area Development of the sexual drive.

Thoughts or sensations initiate sexual arousal. Smooth muscle relaxes in the wall of arteries in the penis, and vasodilation increases blood flow within the penis. The corpora cavernosa and the corpus spongiosum distend with blood and produce an erection. Muscles at the base of the penis contract. Spermatozoa mix with seminal fluid, move into the urethra, and are mixed with mucus from the bulbourethral glands. A series of contractions cause semen to be expelled from the penis through the urethral meatus in a process called ejaculation.

a developmental defect in which one or both of the testicles fail to descend into the normal position in the scrotum undescended testicles

inflammation of the epididymis that is frequently caused by the spread of infection from the urethra or the bladder

Not being able to have children

low sperm count

inflammation of the testes

Cancer of the testicle, usually occurring in men 15 to 35 years of age

A knot of varicose veins in one side of the scrotum

(BPH) enlargement of the prostate gland in older men

Rarely occurs rarely before 40 years of age, but it is the second leading cause of death from cancer in American men; high risk groups include those with a history of multiple sexual partners, STDs and certain viral infections

inflammation of the prostate gland

an inflammation of the glans penis that is usually caused by poor hygiene in men who have not had the foreskin removed by circumcision

When the male penis is curved ventrally with the meatus and the glans in close proximity to each other

painful sexual intercourse

(ED) Inability of an adult male to acheive an erection; impotence.

a narrowing of the opening of the foreskin so that it cannot be retracted (pulled back) to expose the glans penis

a condition in which the male reaches climax too soon, usually before, or shortly after, penetration of the female

a painful erection that lasts 4 hours or more but is not accompanied by sexual excitement

(STD) communicable diseases spread from person to person through sexual contact

Acquired Immune Deficiency Syndrome

immune response

lacking; inadequate

condition of being

gram-negative coccus bacterium -- painful urination with burning and itching -- thin, water discharge from the urethra most common STD

vesicular lesions (blisters) on the penis, scrotum, or anus. when the blisters break, they become skin ulcers. may be flu-like symptoms or no symptoms at all

(CONDYLOMATA ACUMINATA) STD caused by the human papilloma virus warts on perineal region, cervix, anus

painful urination, think yellow discharge from the urethra -- some have no symptoms

seed (ovum or spermatozoon)

flow; discharge

A highly contagious sexually transmitted disease caused by the bacterium Treponema pallidum

an STD caused by a microscopic protozoan that results in infections of the vagina, urethra, and bladder

development of mammary glands in the male caused by altered hormone levels

female; woman

breast; mastoid process

condition; state; thing

blood test + semen test

Test that determines the levels of FSH and LH from the anterior pituitary gland and testosterone from the testes. It is used to diagnose infertility problems.

(PSA) blood test to screen for prostate cancer

prevent perinatal transmission

The testing of DNA samples that exists on the evidence collected from a crime scene

test that analyzes a semen sample for volume, sperm count, motility, and morphology to evaluate fertility or verify sterilization after a vasectomy

detects areas of metastasis from a primary site of prostate cancer

imaging of urinary tract structures using high-frequency sound waves

beyond; higher

sound

process of recording

(DRE) performed on men to screen for prostate enlargement, infection, and indications of prostate cancer

(TSE) a self-help step in early detection of testicular cancer by detecting limps, swelling, or changes in the skin of the scrotum

Surgical removal of the foreskin

removal of one or both testes

endoscopic surgery to move an undescended testicle into its normal position in the scrotum

surgical implantation of a penile prosthesis to correct erectile dysfunction

surgical removal of the prostate

(TURP) excision of the prostate gland by inserting a special endoscope through the urethra and into the bladder to remove small pieces of tissue from the prostate gland

the male sterilization procedure in which a small portion of the vas deferens is surgically removed
