GENERAL HISTOLOGY

Detailed explanation-1: -Myosin filaments are made up of proteins from myosin and meromyosin. Actin is located in the fibres of the muscle, microfilaments, cell membrane, and cell wall.-Myosin is primarily discovered in muscle cells. Actin interacts with myosin to facilitate muscular contraction.

Detailed explanation-2: -Although actin is a prominent contractile protein, the significance of the expression of its various isoforms during development remains unclear. Myosin is the most abundant contractile protein and consists of two heavy and four light chains.

Detailed explanation-3: -In muscle cells, the actin filaments are organized into regular arrays that are complementary with a set of thicker filaments formed from a second protein called myosin. These two proteins create the force responsible for muscle contraction.
