Chapter 14- Reproductive System Flashcards
Androgens:
hormones for male
What are the primary reproductive organs in the male?
Testes
Spermatozoa:
male sex cells
Vas deferens;
ejaculatory duct begins where the seminal vesicles join the vas deferens, & this tube joins the urethra.
Prostate:
Gland the size of a walnut that secretes alkaline fluid, below the bladder.
Scrotum:
Retractable sac- like structure that contains the testes.
Penis:
External cylindrical organ with a slightly enlarged end
Urethra:
Tube that allows booth urine and semen to exit the body
What is the common treatment of prostatitis?
Antibiotics, such as penicillin
What is the common treatment for BPH or prostate cancer?
Laser treatment
Tumors:
Life threatening condition such as testicular cancer.
Infectious diseases:
conditions caused by bacteria, such as syphilis and gonorrhea
Impotence:
The inability to achieve and maintain erection
Inflammatory disorders:
Swollen, painful male reproductive organs like the prostate and epididymis
Genital herpes:
painful genital vesicles and ulcers
Gonorrhea:
painful and frequent urination, discharge form the penis
Syphilis;
chancre at the site of exposure, usually the penis
AIDS:
fever, joint pain, muscle pain, night sweats, and malaise
What is the most prevalent STI?
Genital Warts
What type of urine specimen is obtained to perform a urinalysis?
Random urine specimen
Obsterics:
The branch of medicine that deals with pregnancy, labor, and the postpartum period.
Urologist:
Doctors who specialize in male reproductive disorders, along with female and male urinary system disorders.
Gynecologist:
Doctors who diagnose and treat female reproductive system diseases. Often provider practices both obstetrics and gyno (OBGYN).
Nurse midwives:
Healthcare providers who assist women through pregnancy, labor, and delivery.
Doula:
Woman who assists other women during labor and delivery. Also, may provide support to the family after childbirth.
Gamete:
A mature sexual reproductive cell; spermatozoon or ovum.
Gonad:
Organs that produce sex cells in both males and females.
Testes:
Located in the scrotum, testes are the primary reproductive organ in males. Each testis is about 4 cm wide and 3 cm thick.
Consists of lobules that hold seminiferous tubules where spermatozoa are produced.
Spermatozoa are the male sex cells, where the formation of sperm begins.
Male Reproductive:
- Primary reproductive organ = testes.
-Each testis is oval in shape, measures about 1.6 inches long & 1 inch wide. - Testes are surrounded by white, fibrous capsules & are suspended together is a sac called the scrotum.
- Testes produce gametes = Spermatozoa
- Spermatozoa’s are made up of: Head, Midpiece, and Tail or Flagellum
Head:
Contains the chromosomes in the nucleus
Midpiece:
Contain mitochondria which produces energy
Tail or Flagellum:
used for movement
Spermatogenesis:
formation of sperm
Seminiferous tubules:
Spermatozoa’s are formed in a series of tiny tubes in each testis.
Where do spermatozoa’s travel to when they reach the testis?
Epididymis (Where they are stored and matured)
Epididymis:
is a coiled tube that is almost 20 feet long and found on top of & behind each testis.
-Next, the spermatozoa moves to the Vas deferens.
-Each Vas deferens is 18 inches long that connects to the base of the epididymis & passes along to the side of the testis.
-Deferens travels into the pelvic cavity, just found behind the bladder.
Prostate gland, Seminal Vesicles, & Cowper Gland or Bulbourethral gland):
provides fluid either to nourish or to aid in motility & lubrication.
Semen:
sperm & fluid together makes up.
Glans penis:
Semen exit through the tip of the penis.
Foreskin and/or Prepuce:
at birth the glans penis is surrounded by this called.
Testosterone:
at puberty the interstitial cells start to produce this
-maining reproductive structures & development of sperm.
Cells & Secondary Sex Characteristics:
- Deep voice
-Broad shoulders
-Narrow hips
-Body hair
The penis composed of three columns:
of highly vascular erectile tissue.
Two columns of corpora cavernosa.
Corpus Spongiosum.
Corpus Spongiosum:
fills w/ blood, through the dorsal vein, during sexual arousal.
What should a patient be instructed to feel for during a testicular self-exam?
Hard painless lumps in the testicles
Tenderness when examining the epididymis
How does a provider determine an enlarged prostate?
Digital Rectal Examination (DRE)
What are male sex hormones called collectively?
Androgens
What is true about the testes?
- The scrotum contains the testes.
- Spermatozoa are produced in the testes.
- The testes are the primary reproductive organs in the male.
The urethra in a male is a part of which two systems?
Urinary, Reproductive
What physiological changes occur to result in erection?
- Arteries in the penis dilate.
- Veins in the penis compress.
- Three columns of erectile tissue in the penis become stimulated.
