โ
Muscle bundles/Fascicles
โ
Fascia
(collagenous connective tissue)
โ Each muscle bundle contains a number of muscle fibres.
โ Muscle fibre is a syncitium (sarcoplarm contains many nuclei).
โ Endoplasmic reticulum, i.e., sarcoplasmic reticulum of muscle fibre is the store house of calcium ions.
โ Each muscle fibre has many parallelly arranged myofibrils/ myofilaments.
โ Each myofibril has dark and light bands due to actin and myosin distribution that establish striated appearance.
