GENERAL HISTOLOGY

Detailed explanation-1: -The connective tissue sheath covering each fasciculus is known as perimysium, and the innermost sheath surrounding individual muscle fiber is known as endomysium.

Detailed explanation-2: -The epimysium is a thick connective tissue layer that is composed of coarse collagen fibers in a proteoglycan matrix. The epimysium surrounds the entire muscle and defines its volume.

Detailed explanation-3: -The whole muscle is enclosed by a dense connective tissue sheath called the epimysium. (Epi-greek for upon, mys-greek for muscle). The muscle fibres are divided up into bundles of fibres called ‘fascicles’. Fibrous sheaths that surround the fascicles are called the perimysium (peri is greek for around).
