Explanation:
Answer:
The dense irregular connective tissue that covers muscle fascicles and holds them together is called the epimysium (option a)
Each individual muscle fiber is covered by a layer of connective tissue called the endomysium (option e)
Explanation:
The epimysium is the sheath of dense connective tissue that surrounds the entire set of fascicles that form the muscle. The innervation and irrigation of the muscle reaches the epimysium.
The endomysium is a thin layer of reticular fibers that surrounds muscle fibers individually. There are only capillaries of very small caliber and very thin nerves.
