Muscles that enmesh the spermatic cord and draw the testes closer to the body to keep them warm?
Cremaster muscles
A bundle of connective tissue that passes upward from the testes, through the inguinal canal, into the pelvic cavity
also contains the ductus deferens, blood and lymph vessels and nerves?
Spermatic cord
Subcutaneous muscle the contracts and wrinkles the skin?
Dartos muscle
The ducts in which sperm are produced?
Seminiferous tubules
Included with in the seminiferous tubules are two things what are they?
Epithelium
Sustentacular cells
Germ cells in the process of becoming sperm?
Epithelium
These protect germ cells and promote their development
They provide nutrients, waste removal and growth factors
They secrete a ABP and inhibin to regulate sperm production
They are take junctions between cells that form of blood testes barrier?
Sustentacular cells
Clusters of cells between seminiferous tubules that produce testosterone?
Interstitial cells
The network that the seminiferous tubules lead into?
The Rete testis
The spermatic ducts Are made up of five parts what are they?
Efferent ductules
Epididymis
Ductus deferens
Ejaculatory duct
These carry sperm from the Rete testis to the epididymis?
Efferent ductules
This is the site of sperm maturation and storage?
Epididymis
These transport sperm
They are a muscular tube that continues from the epididymis
It passes through the spermatic cord, runs along the top of the bladder, and unites with the duct of the seminal vesicle behind the bladder?
Ductus deferens
This is where the ductus deference and the seminal duct meet and transport sperm to the urethra?
It passes through the prostate gland and empties into the urethra?
Ejaculatory duct
Passes urine and semen to the outside?
Urethra
There are three accessory glands what are they?
Seminal vesicles
Prostate gland
Bulbourethral glands
These glands are posterior to the bladder
The ducts empty into the ejaculatory duct
Secretion Constitute 60% of semen?
Seminal vesicles
this gland is inferior to the bladder
It’s surrounds the urethra and ejaculatory duct
Secretion constitutes 30% of semen?
Prostate gland
Bulbs at inner end of penis
Ducts lead into the penile urethra
They produce fluid that lubricates the head of the penis and neutralizes the acid of residual urine in the urethra?
Bulbourethral glands
Deposits urine and semen to the outside?
The penis
Internal half?
The root
The External half?
The shaft
Expanded head at the distal end of the penis?
Glans
Skin over the glans?
Prepuce (foreskin)
Tissues that fill with blood during erection?
Erectile tissues
Erectile tissue enclosing the penile urethra?
Corpus spongiosum
Two cylinders of erectile tissue on the dorsal or top side of the penis?
Corpora cavernosa
Stimulates the anterior pituitary to secrete FSH and LH?
GnRH
Stimulate sustentacular cells to secrete androgen binding proteins (ABP)
FSH
Stimulates interstitial cells to secrete testosterone?
LH
Stimulates sperm production in the presence of ABP, inhibits GnRH, Stimulates development of secondary sex characteristics and organs, stimulates growth of sex organs, sustains libido?
Testosterone
suppresses FSH secretion which slows sperm production?
Inhibin
The head of The sperm contains three parts what are they?
The nucleus
Acrosome
Basal body of the flagellum
Two parts of the flagellum or tail of the sperm?
Mid peace
Rest of the tail
This contains haploid or half set of condense chromosomes?
Nucleus
Contains enzymes used to penetrate the egg?
Acrysome
Contains numerous large mitochondria which powers the tail so the tail can move?
Beats as the sperm migrates up the female reproductive tract?
Beats as the sperm migrates up the female reproductive tract?
Rest of tail
How much semen is expelled during Ejaculation?
2 to 5 mL
How many sperm are produced per milliliter?
50-120 million
A clotting enzyme, protein hydrolyzing enzyme is called?
Prostate fluid
Fructose, CHO which produce energy prostaglandins which cause reverse peristalsis helping to bring sperm to egg and proseminogelin are all part of what?
Seminal vesicle fluid
Noncancerous enlargement of the prostate gland?
Prostatic hyperplasia
Second most common cancer in men?
Prostate cancer
Inability to maintain an erection?
Erectile dysfunction
Urethra opens on the ventral side?
Hypospadias
Inability to fertilize an egg?
Infertility
Most common solid tumor in men ages 15 to 34?
Testicular cancer
Abnormal dilation of veins in the spermatic cord?
Varicocele
Bacterial sexually transmitted diseases?
Nongonococcal urethritis
Gonorrhea
Pelvic inflammatory disease (chlamydia or N. gonorrhea, only in women)
Syphilis
Causes urethral discharge and pain in the testes or pelvic region, urethral inflammation?
Nongonoccal urethritis
Pus discharge from penis, abdominal discomfort, genital pain, painful urination, abnormal uterine bleeding?
Gonorrhea
Infection of the female pelvic organs often resulting in sterility?
Pelvic inflammatory disease
Stage one, lesion on penis or vagina; stage II rash, fever, joint pain, and hair loss; stage III cardiovascular damage, brain lesions?
Syphilis
Viral diseases which are there to stay you cannot get rid of?
Genital herpes
Genital warts
Hepatitis B and C
Blisters on penis, labia, vagina cervix, size, buttocks; later lesions appear anywhere on the body?
Genital herpes
Male: lesions on penis, perineum, or anus; female: lesions on cervix, vaginal wall, perineum, or anus?
Genital warts
Inflammatory liver disease?q
Hepatitis B and C
