spermiogenesis

A spermatid undergoes ______________________ by greatly condensing its nucleus, forming a long flagellum with a surrounding mitochondrial middle piece, and forming a perinuclear acrosomal cap.

e. Seminal vesicles

As sperm pass through the male genital ducts, proteins and low-molecular-weight products are added from several sources producing semen. Which of the following provides a nutritive, fructose-rich secretion? a. Interstitial cells of Leydig b. Bulbourethral (Cowper) glands c. Prostate gland d. Epididymis e. Seminal vesicles

secondary spermatocytes

Primary spermatocytes undergo a first meiotic division to form haploid ________________________________.

spermatids

Secondary spermatocytes undergo the second meiotic division to produce small, round _________________, which differentiate while still associated with Sertoli cells.

primary spermatocytes

Stem cells called spermatogonia undergo mitosis and give rise to ________________________.

pseudostratified columnar epithelium

The epididymis is lined by ____________________________________ containing principal cells, which have long stereocilia.

Epididymis

Where does the final maturation of the sperm take place?

Sertoli cells Note: Sertoli cells also produce androgen-binding protein, which concentrates testosterone

Which cells in the testes are the supporting cells?

Leydig cells

Which cells in the testes produce testosterone?

a. Prostate

Which of the following organs is normally characterized by the accumulation of corpora amylacea with increasing age? a. Prostate b. Seminal vesicles c. Bulbourethral (Cowper) glands d. Epididymis e. Ductus (vas) deferens
