From superficial to deep, what is the correct order of structures that would be encountered if a needle was inserted into a testis?
Tunica vaginalis, tunica albuginea, seminiferous tubules
Tunica vaginalis, seminiferous tubules, tunica albuginea
Tunica albuginea, tunica vaginalis, seminiferous tubules
Seminiferous tubules, tunica vaginalis, tunica albuginea
The Correct Answer is A
A. Tunica vaginalis, tunica albuginea, seminiferous tubules: The tunica vaginalis is the outer protective layer, followed by the tunica albuginea (a tough fibrous layer), and then the seminiferous tubules, where sperm production occurs.
B. Tunica vaginalis, seminiferous tubules, tunica albuginea: The seminiferous tubules are deeper than the tunica albuginea, making this order incorrect.
C. Tunica albuginea, tunica vaginalis, seminiferous tubules: This reverses the outer layers, as the tunica vaginalis is superficial to the tunica albuginea.
D. Seminiferous tubules, tunica vaginalis, tunica albuginea: This order is incorrect, as the tunica vaginalis and tunica albuginea are external to the seminiferous tubules.

Correct Answer is D
Explanation
Trabeculae: These are thin connective tissue strands that extend from the capsule of the lymph node into the interior. They help to divide the lymph node into distinct compartments or regions, which include the cortex (outer area) and medulla (inner area). This compartmentalization is important for the organization and function of the lymph node, allowing it to efficiently filter lymph and facilitate the immune response.
Correct Answer is D
Explanation

C. Gametes do not go through cell division: Gametes are produced through meiosis, which is a type of cell division.
D. Gametes go through meiosis: Gametes are produced through meiosis, a specialized form of cell division that reduces the chromosome number by half, allowing for sexual reproduction.
