Male Reproductive System
| Question | Answer |
|---|---|
| male reproductive system | produce,sustain,transport sperm sperm from penis to vagina during sexual intercourse produces testosterone |
| copulation | sperm from male penis to female vagina during sexual intercourse |
| primary organs | male gonads- testes |
| gonads | male sex glands-testes |
| testes | small ovoid glands that develop high in abdominal cavity near the kidneys they produce male germ cells called spermatozoa and secrete testosterone |
| testosterone | secondary sex characteristic changes that occur in male with onset of puberty which include growth of facial hair and deepening voice |
| accessory organs | ducts that transport sperm to outside of body- epididymis, vas deferens,seminal vescicle, ejaculatory duct, urethra,prostate gland |
| supporting structures | scrotum,penis, pair of spermatic cords |
| scrotum | external sac located posterior to penis and suspended from perineum has the testes divides into 2 sacs |
| perineum | area between scrotum and anus in males |
| spermatic cord | contains blood and lymphatic vessels and nerves and vas deferens |
| seminiferous tubules | specialized tiny tubules in testicles responsible for production of sperm |
| epididymus | tightly coiled tubule that resembles a comma sperm mature and become fertile and motile- can move leads to vas deferens |
| vas deferens(ductus deferens) | straight,narrow tube that transports sperm form epididymis to ejaculatory duct |
| ampulla | formed when vasdeferens enlarges it is a sac like dilation |
| ejaculatory duct | formed when vas deferens merges with adjacent seminal vesicle |
| seminal vesicles | secrete thick yellowy fluid caled seminal fluid which is part of volume of semen |
| ejaculation | sexual intercourse expelling semen from male urethra |
| semen | combination of sperm and various secretions expelled from body through urethra during sexual intercourse |
| urethra | ducts from prostate empty into the urethra and transports urine and semen outside of body |
| prostate | gland below bladder surrounds base of urethra ducts transport secretions to urethra thin milky colored alkaline secretions enhance motility of sperm and neutralize secretions if vagina and has muscular action that aids in expelling semen from body |
| bulbourethral glands(cowper's glands) | pair of pea sized glands below prostate gland |
| seminal vescicles | glands that secrete seminal fluid into vas deferens secretes the larges amount of fluid out of prostate and bulbourethral glands |
| volume of semen | 1.5-6.0 ml each ml contains 50-150 million sperm if sperm count is below 10-20 million ml than there could be fertility problems |
| pubic arch | body that is visible pendant portion |
| Penis | male organ of sexual intercourse consists of base that attaches it to pubic arch and tip called glans penis |
| prepuce(foreskin) | loose retractable fold of skin that covers glans penis |
| circumcision | removal of foreskin shortly after birth |
| external urinary meatus | urethra extends length of penis and ends as opening at tip of glans penis |
| erection | penis made of sponge liketissue that contains blood spaces that are empy without esual intercourse but when sexual intercours occurs the spaces fill with blood causing penis to become rigid and enlarge in diameter and length |
| chancre(vanereal sore) | skin lesion usually of primary syplilis that begins as small raised area and develops into red painless ulcer with scooped out appearance |
| cryosurgery | using below freezing temperature to destroy tissue 160 C |
| debridement | removal of dirt damaged tissue and cellular debris form wound or burn |
| dormant | inactive |
| epididectomy | surgical removal of epididimis |
| epididymitis | inflammation of epididymis |
| exudate | fluid pus or serum slowly dischharged from cells or blood vessels through small pores or breaks in cell membranes |
| flaccid | weak,lacking normal muscle tone |
| Kaposi's sarcoma | malignant growth beginning as soft brownish or purple raised areas on feet and slowly spreads in skin spreads to lymph nodes and internal organs mostly in me and associated with aids |
| malaise | feeling of weakness or discomfort |
| malodorous | foul smelling,bad odor |
| motility | ability to move |
| opportunistic infection | infeciton caused by normally non-disease producing organisms that sets up in host where resistance is decreased from surgery,illnesses,disorders |
| orchidopexy | surgical fixation of teticle |
| palpation | feeling with hands |
| pelvic inflammatory disease | inflammation of upper female genital tract cervix,ovaries, uterus, fallopian tubes(salpingitis) |
| perineum | area between scrotum and anus in male and between vulva and anus in female |
| prophylactic | agent or regimen that contributes to prevention of infection and disease |
| prostatectomy | surgical removal of part or all of prostate |
| rectoscope | instrument used to view the rectum that has a cutting and cauterizing loop |
| resectoscope | instrument used to surgically remove tissue form body |
| salpingitis(pelvic inflammatory disease) | inflammation of fallopian tubes |
| spermatozoan(spermatozoon) | mature male germ cell |
| truss | apparatus worn to prevent or blosck herniation of intestines or other organ through opening in abdominal wall |
| vesicles | blisters-small raised skin lesion containing clear fluid |
| andr/o | man,male |
| balan/o | glans penis |
| semin/i | semen |
| zo/o | animal(man) |
| anorchism | no testicles |
| balanitis | inflammation of glans penis and mucous membrane beneath it |
| benign prostatic hypertrophy | benign enlargement of prostate gland creating pressure on upper part of urethra or neck of bladder and causing obstruction of urine flow |
| carcinoma of prostate | malignant growth within prostate gland creating pressure on upper part of urethra most common cause of cancer in men |
| carcinoma of the testes(testicular cancer) | malignant tumor of the testicle that appears as a painless lump in the testicle rare male fertility requires only 1 testicle |
| cryptochordism | condition of undescended teticles absence of 1 or both teticles form scrotum testicle in abdominal cavity or inguinal canal |
| epispadias | congenital defect in ehich urethra opens on upper side of penis at some point near the glans |
| hydrocele | accumulation of fluid in any sac like cavity or duct particularly the scrotal sac or along the spermatic cord |
| hypospadias | congenital defence in which urethra opens on under side of penis instead of at end |
| impotence | inability of male to achieve or sustain erection of penis |
| inguinal hernia | protrusion of a part of intestine through a weakened spot in the muscles and membranes of the inguinal region or the abdomen intestine pushes into and sometimes fills entire scrotal sac in males |
| orchitis | inflammation of testes could be 1 or both from bacterial infection or injury mumps |
| phimosis | tighness of the foreskin of penis that prevents it from being pulled back opening or foreskin narrows and may cause difficult urination usually congenital |
| premature ejaculation | abnormal dilation of veins of spermatic cord leading to testicle |
| prostatitis | inflammation of the prostate gland |
| vericocele | abnormal dilation of veins of spermatic cord leading to testicle abnormal dilation of veins of spermatic cord leading to testicle |
| aquired immunodeficiency syndrome(AIDS) | deadly virus that destroys immune system by invading t cells transmitted though sexual contact, needles,transfusion and mother can pass to baby could be undetected for years takes 1-3 months to detect in blood associated with Karposi's sarcoma 1-10 yrs fo |
| transmissable | capable of being passed from one person to another |
| momgamous | only 1 partner |
| chlamydia | sexually transmitted bacterial infection that causes inflammation of the cervix and inflammation of urethra and epididymis in men |
| genital herpes(venereal herpes) | higly contagious viral infection of genitalia caused by herpes simplex can recur active phase symptoms are present virus can spread dormant-no symptoms can still transmit virus ulcers |
