Final answer:
Nerves, vasculature and stem cells held together by loose connective tissue and encapsulated by endomysium best describe skeletal muscles.
Step-by-step explanation:
The description provided of nerves, vasculature, and stem cells held together by loose connective tissue and encapsulated by endomysium best describes D. Skeletal muscles. In the context of muscle structure, the nerves and vasculature supply the tissue with the necessary resources to function. Stem cells are a potential source for muscle regeneration, while loose connective tissue and the endomysium (a type of connective tissue that encapsulates individual muscle fiber cells) provide support and protection.
