Which structure of the male reproductive system from the following image stores the mature sperm before ejaculation?
Prostate
Seminal Vesicle
Epididymis
Bulbourethral
The Correct Answer is C
A. Prostate: The prostate gland produces seminal fluid that nourishes and transports sperm but does not store mature sperm. Its main function is to contribute to the formation of semen.
B. Seminal Vesicle: The seminal vesicles produce a significant portion of the seminal fluid but do not store sperm. Instead, they provide nutrients for sperm and help form semen.
C. Epididymis: The epididymis is a coiled tube located at the back of each testis where sperm mature and are stored until ejaculation. It plays a crucial role in the maturation process of sperm.
D. Bulbourethral: The bulbourethral glands (or Cowper's glands) secrete a pre-ejaculate fluid that lubricates the urethra but do not store sperm.

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.
