Oxidative phosphorylation occurs within the mitochondria of muscle cells.

A skeletal muscle undergoes hypertrophy mainly by producing many more muscle fibres.

The contractile response of a muscle fibre to a single action potential is called a(n) ____________________.

The actin filaments in sarcomere contain cross bridges.

Match the types of muscles, labelled a. through g., with the properties in question. (Options may be used more than once or not at all.) a.skeletal muscle only b.single-unit smooth muscle only c.cardiac muscle only d.skeletal muscle and cardiac muscle e.skeletal muscle and single-unit smooth muscle f.single-unit smooth muscle and cardiac muscle g.skeletal, single-unit smooth, and cardiac muscles -display(s) pacemaker potentials and slow-wave potentials

The work performed by a muscle is the force it develops divided by distance.

The T tubule ranges transversely to the surface of the muscle cell membrane.

If the load on a muscle is increased, eventually a load will be reached at which the velocity of shortening becomes zero. What is the term for the muscle contraction at this point?

Match the bands, labelled a. through c., with the descriptions. (Options may be used more than once or not at all.) a.A band b.I band c.H zone -composed of thin filaments only

Match the types of muscles, labelled a. and b., with the characteristics. a.isometric contraction b.isotonic contraction -used to accomplish movement

Which of these statements correctly describes foot proteins?

What is the term for the region between two Z lines?

Which of these structures controls the conscious initiation of muscle contraction?

Which muscle type is myogenic?

During aerobic exercise, what is the primary means by which ATP is produced for contractile activity?

Which of these activities is involved in the process of muscle relaxation?

Match the muscle fibre types, labelled a. through c., with the characteristics. (Options may be used more than once or not at all.) a.slow-oxidative fibre b.fast-oxidative fibre c.fast-glycolytic fibre -has myosin ATPase activity

The source of calcium in smooth muscle is the ____________________.

How does an action potential spread rapidly to the central portions of a muscle cell?

Match the muscle fibre types, labelled a. through c., with the characteristics. (Options may be used more than once or not at all.) a.slow-oxidative fibre b.fast-oxidative fibre c.fast-glycolytic fibre -can be transformed into another fibre type by specific training
