Male Reproductive System Flashcards
This part of the external genitalia is an outpouching of the abdominal wall it consists of loose cutaneous sacs and superficial fascia that hangs from the root of the penis
Scrotum
Separates into two sacs that contains one testes each sac
Vertical internal septum
The testicular temperature is regulated by the contraction and relaxation of muscle fibers called
Cremaster muscle
Elevates the testis bringing them closer to the pelvic cavity in response to cool temperature or the sense the testes moving them farther away the pelvic cavity in response to heat
CreMaster muscle
Testicular temperature is regulated _____ below normal body temperature to ensure production in survival of spermatozoa
2-3 degrees
These are oval shape glands confined in the scrotum
Testes (singular: testis)
Consist of the vas deferens, nerves, and blood vessels such as testicular arteries veins and lymphatic vessels that oxygenate drain and carry testosterone to the body.
Spermatic cord
The tunica albuginea forms extension called septa that consequently divides the testes into compartment called
Lobules
Each lobule contains ______ seminiferous tubules
1 to 4
Are tightly coiled tubes where sperm are produced in a process called spermatogenesis
Seminiferous tubules
Are found in the spaces between adjacent seminiferous to bills these cells secrete testosterone or hormone that assist in the descent of the testicles and development of the external male genitalia during prenatal secretion and development of male secondary sexual characteristic during puberty
Leydig cells
The follicle stimulating hormones stimulates the _____ and speeds up spermatogenesis
Sertoli cells
Luteinizing hormone stimulates leydig cells that secretes __________
Testosterone
This hormone inhibits the release of FSH to slow down the production of sperm
Inhibin
Controls the development growth and maintenance of male sex organs, stimulates muscle buildup and bone development, protein annabolism, causes maturation of sperm cells, causes thyroid cartilage enlargement that causes deepening the voice
Testosterone
Is the process in which a sperm is produced by the seminiferous to bills of the testes
Spermatogenesis
Spermatogenesis entire process takes about _____ days
64 to 72
Is known as the male gamete also known as sperm cell
Spermatozoa
About what million sperms are produced daily via spermatogenesis
300 million
The sperm have a life expectancy of __ hours inside the female reproductive system
48
How many chromosomes do we have
23
Its Main function is the transport of sperm cells from the body
Ducts system
Is a comma shaped organ that is made up of highly convoluted tube that is roughly 6 m long. this is found at the posterior lateral side of the testis
Epididymis
Also called Seminole duct this is a straightened chord that starts from the epididymus via the spermatic court through the inguinal canal and arches over the urinary bladder
Vas deferens
Consists of the doctor’s deference testicular artery autonomic nerves veins and lymphatic vessels The structure is considered a supporting structure of the male reproductive system
Spermatic cord
Is located at the base of the bladder it is a vicious yellowish and alkaline fluid that contains fructose prostaglandins vitamin c clotting proteins and other substance that nourish and activate the sperm
Seminole vesicle
Seminole vesicle secretes ____ percent of the ejaculates total volume which is produced mainly during ejaculation
60%
Is a donut shaped gland that encircles the upper prosthetic part of the urethra and its size is that of a chestnut
Prostate gland
Prostate gland secretes about ____ percent of the ejaculate volume characterized to be milky and slightly acidic
25
Is a pea size gland inferior the prostate this gland secretes mucus for lubrication and a protective alkaline substance that neutralize acid to decreasing sperm damage in the urethra
Bulbo urethral gland
Liquid semen coagulates within __ minutes upon ejaculation due to the fibronogen from the seminal vesicle
5
The average volume of semen is about
2.5 to 6 ml
Is the male organ of copulation that delivers spermatozoa to the female reproductive tract is contain the urethra which is the passageway for semen and urine it is cylindrical in shape and consists of a body glands penis and a root
Penis
The body of the penis is composed of three cylindrical masses of tissue which are
2 corpus cavernosa and 1 corpus spongiosum
It is the final excretory organ of urination
Penis
Hairless thin skin that’s adhere so loosely freely and movable allowing for expansion of the erect penis
Shaft
What are the three parts of the penis
Root, shaft, and glans penis
The head of the penis
Glans penis
For uncircumcised mail it is the foreskin that covers the glands
Prepuce
Loughed epithelial cells in mucus collect between glands and foreskin forming a white cheese-like substance called
Smegma
Involves removal of the purpose or foreskin of the penis
Circumcision
Responsible for moving sperm
Ducts
Are used in assessment of pre adolescent and adolescent males
Tanner’s stages of maturation
Affecting men older than for teachers of age cause in unknown but during aging fibromascular structures of the prostate gland atrophy and collagen gradually right places the muscular element of the prostate
Benign prostate hyperplasia (BPH)
Impotence failure to consistently maintain a sufficiently ridged erect penis to allow for sexual intercourse
Present as a lack of desire or inability to ejaculate
Erectile dysfunction
A sexually transmitted infection caused by a bacteria that is also sometimes called “the clap”, “tulo or “drip”
Gonorrhea
Its a sexually transmitted infection We are one or more sores develop on your genitals
Syphilis
Are type of sexually transmitted infection that causes warts small bumps or growths to form in and around your genitals and rectum
Genital warts
Is defined as inability to attract the skin (foreskin or prepuce) covering the head of the penis
Fimosas
Happens to people with partially circumcised or uncircumcised penises this medical emergency happens when the foreskin is unable to be thrown back down over the glands of the penis
Paraphimosis
Is a birth defect in boys in which to opening of the urethra is not located at the tip of the penis
Hypospadias
It’s a rare birth defect located at the opening of the urethra theoreta does not develop into full tube in the urine access the body from an abnormal location
Epispadias
A condition in which one or both of the testes fail to descend from the abdomen into the scrotum
Cryptorchidism
Occurs if a small part of the intestine drops into the scrotum with the testes
Inguinal hernia
