Gross or Macroscopic Anatomy studies:

• A. Structures too small to be seen with the naked eye.
• B. Large body structures visible to the naked eye.
• C. The cellular components of tissues.
• D. The development of an embryo.

Answer: (B)

Gross or macroscopic anatomy focuses on structures large enough to be seen without a microscope, such as organs, bones, muscles, vessels, and entire organ systems, and how they relate to each other in the body. You study these by dissection, surface observations, and imaging that reveals large structures. The other descriptions refer to areas studied with magnification (microscopic anatomy, like cells and tissues) or to development (embryology), which is why they don’t fit gross anatomy.
