d. Seminal Vesicle
B
Scalloped Appearance

a. 1st fraction
b. 2nd fraction
c. 3rd fraction
d. NOTA
C
On seminanalysis, patient was noted to have sperm with irregular shape. In which phase of spermatogenises could this have resulted from
a. Golgi Phase
b. Cap Phase
c. Maturation Phase
A
The midpiece of the sperm cell is related to which organelle
a. RER
b. Nucleus
c. Golgi Apparatus
d. Mitochondria
D
Contraction of these structures causes the movement of the spermatozoa into epididymis. A. Seminiferous epithelium B. Myoid cells C. Leydig cells D. Sertoli Cells
B
Which feature differentiates spermatogonia from other cells in the seminiferous epithelium? A. Dome-shaped cell B. Near lumen C. Condensed chromatin D. Notched, irregular nucleus
A
This is the process of extrusion of spermatozoa into the lumen of the male reproductive tract…
-Spermiation
This structure protects the corpora cavernosa…
-Tunica albuginea
The main neurotransmitter used by the body to produce an erection.
Nitric oxide
All of the following are secreted by the Sertoli cells EXCEPT: A. Estradiol B. Acid phosphatase C. Androgen-Binding Protein D. Meiosis Inhibiting Factor
B
Effect of testosterone A. Increased sebum production B. Male pattern baldness C. Low pitched voice D. Prostate hypertrophy
C
Contraction of these structures moves newly formed spermatozoa from seminiferous tubules to the epididymis
A. Seminiferous tubule
B. Rete testis
C. Myoid cells
D. Leydig cells
C
Which of the following emphasizes the need for a blood-testis barrier?
A. Spermatocytes are halted at prophase of meiosis I
B. Spermatids still immobile
C. Sertoli cells have lateral process
D. Spermatocytes may have cell surface antigens that are radically different from spermatogonia
D
Which of the following is the reason for the unpredictability of the time it takes for the spermatogonia to develop into spermatocytes?
A. Prolonged prophase I
B. Short meiosis II
C. Golgi phase of spermatogenesis
D. Mitosis of spermatogonia
