ANA300Y1 Lecture Notes - Lecture 11: Dense Irregular Connective Tissue, Neurovascular Bundle, Muscle Fascicle
Document Summary
Word roots used in reference to muscle tissue: sarcos (gr. Flesh , different components of muscle tissue) e. g. sarcolemma; sarcoplasm. Each skeletal muscle fibre will be covered with endomysium then merge with perimysium. Tendons & aponeuroses (connect this muscle to whatever it will pull on) collagen fibres of epi-, peri-, endomysium blend with those of tendon for attachment (which will ultimately attach to a bone) Striations these black things are nuclei, cells having a single nucleus but rbc no nucleus, this is the type of cell with many nuclei, since formed by fusion of multiple primordial cells. Myoblasts will fuse during development to form larger cells these will fuse and form larger cells. To get a muscle fiber explains the fact that it is multinucleate, since nuclei remain and also explains size of muscle fibers, huge cells since formed from fusion of all these primordial cells.
