Document Summary
Slide 2: animals are characterized by having 2 broad types of muscle tissues: striated muscles and smooth muscles, striated muscles are characterized by having banding patterns. In smooth muscles, the same proteins are present but they"re not organized in a regular fashion so you don"t get the bands. Slide 3: here we have a muscle. The tendons are connective tissues that attach the muscle tissue to the bone. The connective tissue that makes up the tendon is continuous with the layers of connective tissue that surround the entire muscle: within the myofibre are cylindrical structures called myofibril. Within each muscle cell, there are many myofibrils. If you want to be specific, the type of actin found in muscles is known as alpha actin. Actin plays a major role within cell cytoskeleton, in the muscle it"s a different kind of actin, but in muscles it"s just alpha actin: a single monomer, an individual actin protein, is referred to as g-actin.
