What is your diagnosis?
Seminiferous tubules
What is your diagnosis?
Seminiferous tubule.
What type of spermatogenic cell is at the tip of the arrow?
Early spermatid.
What type of spermatogenic cell is at the tip of the arrow?
Primary spermatocyte.
The nucleus at the tip of the arrow belongs to what cell?
Myoid cell.
What is your diagnosis?
Seminiferous tubule interstitium with Leydig cells.
What type of cell is this?
Sertoli cell.
What type of cell is found at the tip of the arrow?
Sertoli cell
What is the structure outlined by the box?
Tubulus rectus
All of the following are characteristics of the cells at the pointer EXCEPT:
a) Cholesterol esters
b) Multiple tight junctions
c) Abundant SER
d) Mitochondria w/ tubular cristae
e) De novo steroid synthesis
B - Multiple tight junctions
These are Leydig cells. Sertoli cells form the tight junctions as part of the blood-testis barrier.

a) Leydig cells
b) Primary spermatocytes
c) Residual bodies
d) Sertoli cells
e) Spermatids
D - Sertoli cells
