ZOO 3731 Lecture Notes - Lecture 3: Vas Deferens, Seminiferous Tubule, Rete Testis
Document Summary
Where are the seminiferous tubules found within the septa. Two types of seminiferous tubules cells sertoli and germ cells sertoli cells blood testes barrier; non dividing support cells germ cells spermatoza. Leydig cells interstitial cells, produce hormones called androgens. Rete testis: function receive sperm from seminiferous tubules. Efferent ductules connect rete testis to the epididymis. Epididymis; function highly convoluted tubule, sperm maturation (in the cauda) Conducts sperm and some components of seminal fluid from the ductus deferens to the prostatic urethra; formed by the union of the ductus deferens and the seminal vesicle. Male urethra transports both semen and urine to the outside of the body. Three glands that secrete seminal plasma seminal vesicles, prostate gland, bulbourethral gland. Seminal vesicles: function paired glands that secrete a viscous white-ish yellow, alkaline fluid containing fructose and prostaglandins. Prostaglandins: function helps dialate the cervix so that sperm can enter.
