Lesson 3 Male Repro Flashcards
Parts of male reproductive system
Testis
Epididymis
Vas deferens
Penis
Accessor glands : prostrate, seminal vesicles, bulbourethral
They produce sperm and testosterone
Also surrounded by tunica albuginea
Testis
Parts of the testes
Parenchyma and stroma
It is a functional component of the testes organ
Parenchyma
It is round cell with oval nuclei: single layer against basal lamina
Spermatogonia
It is two or more layers of round cell in prophase stage also the largest cell in the tubule
Primary spermatocytes
Immediately divide into daughters spermatids
Secondary spermatocytes
It appears the toward the lumen of the tubule
Spermatids
Tadpole like cells with head mid piece and tail
Spermatozoa/sperm
It is simple columnar cell in seminiferous tubules also span from the basal lamina
provide nutrients
Sertoli cell
It is connective tissue component
Stroma
This is where the sperm are stored before ejaculation
Epididymis
This is where the sperm are stored before ejaculation
Epididymis
It is a long muscular tube that travels from the tail to epididymis into the pelvic cavity
Vas deferens
It is a tube that carries urine and expel semen
Urethra
Is a male copullary organ that transfers semen to the vagina also a passage of urine
Penis
Parts of accessory gland
Prostate, seminal vesicle, bulbourethral
Accessory gland that are absent in dogs
Seminal vesicles & bulbourethral
Male reproductive system of the rooster
Testes and vas deferens
Located along the chickens back near the top of kidneys
Testes
Duct through which sperm are transported from the testes. Main area of sperm storage in male chickens
Ves deferens
