A. Fully mature and leave the epididymis: The acrosome does not play a role in sperm maturation or their release from the epididymis.
B. Travel through the male reproductive ducts: Movement through the reproductive ducts relies on the sperm's flagellum and muscle contractions, not the acrosome.
C. Develop a full set of chromosomes: Chromosome development occurs during spermatogenesis and is unrelated to the acrosome.

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.
