Anatomy of a to each other. Nucleus is centrally located in smooth and peripherally located in striated muscles. The cells that have the same structure, features and perform the same functions form a particular type of tissue. Muscle cells are long and elongated so-called muscle fibres and contain actin and myosin contractile proteins.. Function: Contractile proteins present in them helps in contraction and relaxation which brings movement and locomotion. The non-striated (smooth) muscle cell is spindle-shaped and has one central nucleus.
