This type of tissue is found in skeletal muscles and is responsible for the voluntary movements of bones.

The myofibrils are bundles of interconnected protein filaments of striated muscles. The filaments (myofilaments) included in the myofibrils are mainly thick filaments (myosin), and thin filaments (actin). The contractile functional unit of the myofibril is called the sarcomere

The myofibrils have a characteristic banding pattern detected under a light microscope referred to as striations

The main function of the myofibrils is to produce muscle contraction and relaxation.

Terminology English: Myofibrils
Latin: Myofibrilla
Definition Bundles of interconnected protein filaments of striated muscles
