The Male Reproductive System Flashcards
1
Q
Parts of the Sperm (3)
A
- head = genetic material
- midpiece = mitochondria for energy
- tail = to propel forward
2
Q
- Corpus spongiosum
2. Corpora cavernosa
A
- ventral column of the penis
2. two dorsal columns of the penis
3
Q
Spermagenosis
A
- formation and development of sperm
4
Q
Acrosome
A
- contains enzymes that facilitate the penetration of an ovum’s membrane
5
Q
Epididymis
A
- single, coiled tube about 6m in length; it’s where sperm mature and develop motility
6
Q
Epididymitis
A
- inflammation of epididymis
7
Q
Ductus (vas) Deferens
A
- sperm pass through the pelvic cavity via this duct
8
Q
Ejaculatory duct
A
- passes through the prostate gland
9
Q
Urethra
A
- Sperm leave the body via this duct
10
Q
Scrotum
A
- holds the testes away from the body to reduce their temperature
11
Q
Glans
A
- proper name for the “head” of the penis
12
Q
Foreskin
A
- structure covers the glans on an unaltered penis
13
Q
Circumcision
A
- surgical removal of the foreskin
14
Q
Semen
A
- mixture of sperm and secretions of accessory glands
15
Q
Seminal Vesicles
A
- structures provide the fructose-rich portion of semen
16
Q
Prostate Gland
A
- urethra passes through this structure, which provides about 30% of seminal volume
17
Q
Bulbourethral (Cowper’s) glands
A
- structures secrete a fluid that is sometimes referred to as “pre-ejaculate
18
Q
Order of Organs (5)
A
- Testes
- Epididymis
- Ductus (vas) deferens
- Ejaculatory duct
- Urethra
19
Q
Testosterone
A
- “masculinizes”
- promotes development of male accessory organs
- stimulates protein anabolism and the development of muscle strength
20
Q
Hydrocele
A
- accumulation of watery fluid in the scrotum
21
Q
Epispadias
A
- urethra opens on the top of the glans or shaft of the penis.
22
Q
Prostate cancer
A
- leading cause of cancer deaths in men
23
Q
Phimosis
A
- tight foreskin that cannot be retracted over the glans
24
Q
Hypospadias
A
- urethra opens on the underside of the glans or shaft of the penis
25
Impotence/Erectile dysfunction
- failure to achieve erection of the penis
26
Benign Prostatic Hypertrophy
- enlargement of the prostate common in older men
27
Paraphimosis
- foreskin cannot be replaced to usual position when retracted
28
Inguinal hernia
- protrusion of abdominopelvic organs, possibly into the scrotum
29
Infertility
- reduced reproductive ability
30
Testicular cancer
- cancer most common in men aged 25-35
31
Cryptorchidism
- Undescended testes
32
Sterility
- Inability to reproduce
33
Oligospermia
- Inability to reproduce
