Microanatomy of the Male and Female Reproductive Systems Flashcards
The tunica albuginea divides the testes into ______________.
lobules
Inside the lobules are _____________.
seminiferous tubules (where spermatogenesis takes place)
After spermatogenesis, what structure do sperm pass through to get to the ductus deferens?
The rete testes
Sperm enter the epididymis at the _________.
head of the epididymis
Where are Leydig cells?
Outside the tubules
Describe what a histologic slide of the seminiferous tubules looks like.
It is divided into ducts. The tissue that surrounds the ducts is spermatogonia.
The cells on the basal layer of the seminiferous tubule with larger nuclei are ________________.
spermatogonia
The spermatogonia divide to produce ___________.
first spermatocytes (the cells that undergo the first meiosis)
Secondary spermatocytes divide to produce ____________.
haploid spermatids (which then develop into sperm)
The vasculature is all ___________ to the seminiferous tubules.
outside
What lines the inside of the ductus deferens?
Ciliated epithelium that helps propel sperm along
The ductus deferens is composed of ______________.
fibromuscular tissue
What is in the spermatic cord?
Ductus deferens (largest cord; fibromuscular)
Testicular artery
Pampiniform plexus
The vas deferens has three layers of muscle: ___________________.

Middle: circular
Outmost: outer longitudinal
The entire length of the ductus deferens is __________ epithelium.
columnar
The _______________ are composed of a honeycomb-like network of fibromuscular tissue.
