Wish the diagram were colored but the description and explanation is spot on.
I have read three books on Anatomy from a Yoga perspective but fairly applicable to understand all sorts of physical exercises or movements, and my personal ranking is as follows :
#1. Concise Book of Yoga Anatomy by Jo Ann Staugaard-Jone.
#2. Anatomy of Movement by Blandine Calais-Germain
#3. Yoga Anatomy by Leslie Kaminoff
#1 is Phenomenal. Lays great emphasis on all aspects of musculoskeletal system like ligaments, tendons, aponeurosis, nerves, etc.
Have great great things about Ray Long's book but yet to read that one, maybe that can up this one.
#2 is Good. Simple language. Lot of space to make notes. I use it as my anatomy notebook rather than textbook.
#3 is Not Good. Arrange by type of pose rather than muscle group. Less detail about each muscle, and more about their state in each pose, which you can automatically figure out if you understand the muscle groups.
