2D and 3D

I often wonder how people learn anatomy from textbooks. 3D is so different from 2D. Like the trapezius muscles, for example. Do you know the upper fibres over the shoulders like a shawl, to finish on the clavicle, around 1/3 to the edge? Beautiful! (Though in the pages of a book, they look flat like a diamond shaped pancake).

As for serratus anterior and posterior, the actual layout get even more complicated.....what fun! Is it necessary, I hear you ask. Of course! Because if you pull your serratus, it hurts when you breathe, and it feels like heart attack.

I love anatomy!
