What do seminiferous tubules produce
Spermatozoa
What do interstitial cells (leydig) cells produce
Testicular androgens
What is the path of the seminiferous tubules to the epididymus
Straight tubules Rete testis Ductuli efferentes Epididymus
What epithelium lines the seminiferous tubules
Complex stratified epithelium
At are the two types of cells in the seminiferous epithelium
Supporting cells (serotoli cells) Cells of spermatic lineage
What is the process by which spermatozoa are formed
Spermatogenesis
Spermatogenesis begins with what cell
Spermatogonium
What is the process of cells in spermatogenesis
Spermatogonium Type a spermatogonia Type b spermatogonia Primary spermatocytes Secondary spermatocytes Spermatids
What are the largest cells of spermatic lineage
Primary spermatocytes
What is the genetic number for primary spermatocytes
2n 4d
What is the genetic number of secondary spermatocytes
1n 2d
What is the genetic number of spermatids

What are the three stages of spermiogenesis
Golgi Acrosomal Maturation
What happens in the Golgi phase of spermiogenesis
Single Acrosome forms Flagellar axoneme begins to form
What happens in the acrosomal phase
Acrosome is formed Mitochondria aggregate around middle piece Flagella is formed
What happens in the maturation phase
Excess cytoplasm is shed Spermatozoa are released
What does testicular fluid contain
Steroids Proteins Ions Androgen binding protein
True or false: Serotoli cells divide during the reproductive period
False
What type of junctions bind serotoli cells
Occluding and gap
Sertoli cells separate the seminiferous tubule into what two compartments
Basal compartment Ad luminal compartment
What three things do Sertoli cells release
Fluid for spermatozoa Androgen binding protein Inhibit
What does androgen binding protein do
Concentrates testosterone
What controls ABP
FSH and testosterone
What does inhibin do
Suppresses FSH
