Question

Mark the correct sequence of the layers of testis from inner to outer side.

• A. Tunica vaginalis $\rightarrow$ Tunica albuginea $\rightarrow$ Tunica vasculares
• B. Tunica vascularis $\rightarrow$ Tunica vaginalis $\rightarrow$ Tunica albuginea
• C. Tunica vaginalis $\rightarrow$ Tunica vasculares $\rightarrow$ Tunica albuginea
• D. Tunica albuginea $\rightarrow$ Tunica vasculares $\rightarrow$ Tunica vaginalis

Hint:

The correct sequence of testis layers is: Tunica vaginalis (outer), Tunica vasculares (middle), and Tunica albuginea (innermost).

Answer 1

The Correct Option is C

Step 1: Understanding the layers of the testis.
The testis is surrounded by three layers: the outermost layer is the tunica vaginalis, followed by the tunica vasculares (which contains blood vessels), and the innermost layer is the tunica albuginea.
Step 2: Analyzing the options.
(A) Tunica vaginalis $\rightarrow$ Tunica albuginea $\rightarrow$ Tunica vasculares: Incorrect — The blood vessels are located between the tunica vaginalis and tunica albuginea, not at the outermost.
(B) Tunica vascularis $\rightarrow$ Tunica vaginalis $\rightarrow$ Tunica albuginea: Incorrect — The correct order of the layers is not as described in this option.
(C) Tunica vaginalis $\rightarrow$ Tunica vasculares $\rightarrow$ Tunica albuginea: Correct — This is the correct sequence from outermost to innermost layer of the testis.
(D) Tunica albuginea $\rightarrow$ Tunica vasculares $\rightarrow$ Tunica vaginalis: Incorrect — The tunica albuginea is the innermost layer, not the outermost.
Step 3: Conclusion.
The correct answer is (C) Tunica vaginalis $\rightarrow$ Tunica vasculares $\rightarrow$ Tunica albuginea.
