1. the connective tissue that surrounds each muscle fiber is called the click to select.
2. the specific name for a muscle fibers plasma membrane is the click to select.
3. each myofibril is made of up of several click to select.
4. terminal cisterns are a structural feature of the organelle called the click to select.
5. in a muscle fiber, the click to select is adjacent to a terminal cistern, so the action potential can stimulate calcium ion channels.

Explanation:

1. Endomysium is the connective - tissue surrounding each muscle fiber.
2. Sarcolemma is the name for a muscle fiber's plasma membrane.
3. Myofibrils are made up of sarcomeres.
4. Terminal cisterns are part of the sarcoplasmic reticulum.
5. T - tubules are adjacent to terminal cisterns to facilitate calcium ion channel stimulation.

Answer:

1. endomysium
2. sarcolemma
3. sarcomeres
