There are four types of triads: major, minor, augmented, and diminished. Major triads consist of a root, major third, and perfect fifth. Minor triads have a root, minor third, and perfect fifth. Augmented triads have a root, major third, and augmented fifth. Diminished triads have a root, minor third, and diminished fifth.
A muscle triad includes one T-tubule and two terminal cisternae of the sarcoplasmic reticulum. This arrangement is responsible for regulating calcium release during muscle contraction in skeletal muscle cells.
The largest skeletal muscle connective tissues are fascicles, which are bundles of fibers, which are made of myofibrils, which consist of myofilaments.
A single muscle cell is called a muscle fiber.
Each muscle fiber is also called a myofiber.

The smaller fiber in a muscle fiber is called a myofibril. A band of tissue that connects bone to bone is called a ligament.
