connective tissue and fascicles Flashcards
endomysium
thin sleeve of loose connective tissue that surrounds each muscle fiber. the smallest component of connective tissue and it creates room for blood capillaries and nerve fibers to reach every muscle fiber.
perimysium
it is the second smallest component of connective tissue sheath that wraps muscle fibers together in bundles called fascicles. it carries the larger nerves and blood vessels as well as stretch receptors called muscle spindles.
epimysium
the second largest connective tissue and it is a fibrous sheath that surrounds every muscle. on its outer surface, the epimysium grades into the fascia, and its inner surface issues projections between the fascicles to for the perimysium.
fascia
the largest sheet of connective tissue that separates neighboring muscles or muscle groups from each other and from the subcutaneous tissue.
