-The splitting of a primary spermatocyte into two secondary spermatocytes, each having 23 chromosomes (half the number in primary spermatocyte)
Basic process of Meiosis II
-Duplication of chromosomes
-The splitting of the two secondary spermatocytes into 2 spermatids (equaling to 4 spermatids); however chromosomes are duplicated in the secondary spermatocyte in order for each spermatid to have 23 chromosomes
What are the major differences between spermatogenesis vs. oogenesis?
Spermatogenesis yields 4 cells while oogenesis yields only 1.
Know the parts of the testes (4)
-Tunica albuginea: tough, fibrous tissue that encloses the testes
-Lobules: compartments in the testis that hold seminiferous tubules
-Seminiferous tubules: lined with a special stratified epithelium containing spermatogenic cells that give rise to sperm cells
-Interstitial cells: between seminiferous tubules that produce and secrete male sex hormones (testosterone)
Tightly coiled tube that connects testis to vas deferens and supplies glycogen; partial maturation of sperm cells occurs here
muscular tube that connects epididymis to ejaculatory tube and uses peristalsis to transport sperm
