1. Where are Sertoli cells located in the testis?
A.
Inside the seminiferous tubules
B.
Inside the epididymis
C.
In the prostate gland
D.
Around the urethra
Correct Answer:
Inside the seminiferous tubules
Explanation:
Sertoli cells are located within the seminiferous tubules of the testis.
2. Sertoli cells are found among which cells in the seminiferous tubules?
A.
Developing germ cells
B.
Red blood cells
C.
Liver cells
D.
Nerve cells
Correct Answer:
Developing germ cells
Explanation:
Sertoli cells lie among the developing germ cells within the seminiferous tubules.
3. Sertoli cells form part of the lining of which structure?
A.
Seminiferous tubules
B.
Urinary bladder
C.
Vas deferens
D.
Seminal vesicle
Correct Answer:
Seminiferous tubules
Explanation:
Sertoli cells are supporting cells located in the epithelial lining of seminiferous tubules.
4. Which testicular structure contains Sertoli cells?
A.
Seminiferous tubules
B.
Interstitial spaces only
C.
Blood vessels only
D.
Tunica vaginalis
Correct Answer:
Seminiferous tubules
Explanation:
Sertoli cells are present inside the seminiferous tubules rather than in the surrounding interstitial spaces.
5. Sertoli cells extend from the basement membrane toward which part of the seminiferous tubule?
A.
The lumen
B.
The scrotal skin
C.
The epididymal duct
D.
The prostate capsule
Correct Answer:
The lumen
Explanation:
Sertoli cells extend from the basement membrane toward the lumen of the seminiferous tubule.
6. Which cell is located within the seminiferous epithelium?
A.
Sertoli cell
B.
Leydig cell
C.
Prostate cell
D.
Epididymal muscle cell
Correct Answer:
Sertoli cell
Explanation:
Sertoli cells are located within the seminiferous epithelium, while Leydig cells are outside the tubules.
7. Sertoli cells are located on which side of the seminiferous tubule wall?
A.
Within the tubule lining
B.
Only in the outer scrotal wall
C.
Inside the urinary bladder
D.
Within the prostate gland
Correct Answer:
Within the tubule lining
Explanation:
Sertoli cells are components of the lining of the seminiferous tubules.
8. Which location distinguishes Sertoli cells from Leydig cells?
A.
Sertoli cells are inside seminiferous tubules
B.
Sertoli cells are inside blood vessels
C.
Sertoli cells are in the epididymis
D.
Sertoli cells are in the scrotal skin
Correct Answer:
Sertoli cells are inside seminiferous tubules
Explanation:
Sertoli cells are found inside seminiferous tubules, whereas Leydig cells are located in the spaces between them.
9. A microscopic section of a seminiferous tubule shows a supporting cell between germ cells. Which cell is it most likely to be?
A.
Sertoli cell
B.
Leydig cell
C.
Sperm cell in the epididymis
D.
Smooth muscle cell
Correct Answer:
Sertoli cell
Explanation:
Sertoli cells are supporting cells situated among the germ cells within seminiferous tubules.
10. Where would a Sertoli cell be observed in relation to a seminiferous tubule?
A.
Between the basement membrane and the lumen
B.
Only outside the testis
C.
Inside the urinary bladder
D.
Within the seminal vesicle
Correct Answer:
Between the basement membrane and the lumen
Explanation:
Sertoli cells extend through the seminiferous epithelium from the basement membrane toward the lumen.
