Male Reproductive System by opstemy

What is the function of the male reproductive system?

produce, stores, provides nourishments, and transports gametes to ensure the continued existence of the human species.

What is the term for when one or both testes do not descend?

Cryptorchidism

The spermatic cords extend from the pelvic cavity to testes and contain what?

vas deferens, blood, and nerve supply

Where do inguinal hernias occur and which sex do they occur in most often?

occurs in the inguinal canal and mainly in males

For sperm development, how many degrees cooler must the sperm be kept at in order to develop properly? And what muscles help aid in this adjustment by pulling and lowering the testes?

2 degrees cooler than body temperature, Cremaster and Dartos muscles

This tightly coiled tube, located in the testes, is where the place of sperm production takes place?

Seminiferous tubules

These cells are found in spaces between seminiferous tubules and produces sex hormones: androgens and testosterone

Interstitial cells

The rete testes is the passageway that leads from the

seminiferous tubules

What connects rete testes to the epididymis

efferent ductules

What is the beginning of the male reproductive tract?

Epididymis

What stores, protects, and matures spermatozoa after detaching from sertoli (nanny) cells

epididymis

Starting at the epididymis, what is the sequence in the male reproductive tract

Epididymis, Vas Deferens, Ejaculatory Duct, and Urethra

What are three accessory glands of the male reproductive system

seminal vesicles, prostate gland, and bulbourethral gland

In the Seminal Vesicles, where does it drain into? how much does it contribute to the total volume of ejaculant? what does it contain?

Drains into ejaculatory duct, 60% of the volume, contains fructose, prostaglandin, and fibrinogen

In the prostate gland, what does it contain? and what is this a common area for?

Contains antibiotics to prevent urinary infection, common area for male cancer

Which accessory gland helps make semen alkaline?

Bulbourethral gland

how many sperms are released during ejaculation

300 million

What makes up 95% of ejaculate and is a mixture of fluids from accessory glands

Seminal fluid

What do the enzymes in the semen do?

dissolve vaginal secretions, an antibiotic to kill bacteria, coagulates semen by fibrinogen which turns into fibrin

Fibrolysin dissolves clot after

15-30 minutes

What is the corpora cavernosum

erectile tissue, paired structures, extends length of shaft, each surrounds a central artery

What is the Corpus spongiosum

erectile tissue that surrounds the urethra, extends to tip of penis, expands the glans

What is a diploid?

2 sets of chromosomes, regular mitosis

What is a haploid?

one set of chromosomes, meiosis

What is spermatogenesis?

production of sperm

What are sertoli cells?

prevent immune system from attacking developing sperm, circulates FSH & testosterone, secretes inhibin, helps in fetal development of testes

What are sperm cells

mobile carrier of genetic material
