Two terminal cisternae and a T-tubule
For skeletal muscle, a triad includes a T tubule with a sarcoplasmic reticulum and a terminal cisterna on either side. Within a muscle fiber there are thousands of triads.

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.

The smaller fiber in a muscle fiber is called a myofibril. A band of tissue that connects bone to bone is called a ligament.
The sacromere with the proteins actin and myosin allow the muscle cell (fiber) to contract.
