10 Questions2 MinutesCreated by MuscleMaster101

Which sentence/sentences is/are true?

Sarcoplasmatic reticulum is storing Ca2+.

Skeletal muscles are derived from fused myoblasts

Triad is present within the cardiac muscle

Caveolin 3 is involved in reparation of the sarcolemma

Which sentence/sentences are true?

The oval nuclei are located peripherally under cell membrane only in skeletal muscle.

Each fiber of skeletal muscle is surrounded by dense connective tissue of epimysium

Cardiac muscle cells posses one or two centrally located nuclei.

In smooth muscle sarcomeres are arranged in myofibrils

The sarcomere extends from M line to M line.

The dense bodies of smooth muscle cells are composed of actin.

The dense bodies contain alpha-actinin and are present in smooth muscles.

What is true about endomysium?

Surrounds the whole muscle

Is located between perimysium and epimysium

Is delicate, reticular connective tissue.

Surround the external lamina of individual muscle fibers

Surrounds the entire muscle

Capilarries form a rich network within the endomysium.

What is true about the skeletal muscle contraction?

To trigger a muscle contraction, calcium has to bind to myosin in smooth, skeletal and cardiac muscle cells

During the skeletal muscle contraction energy is released from ATP.

To trigger a muscle contraction, calcium has to bind to Troponin C in skeletal and cardiac muscle cells.

To trigger a muscle contraction, calcium has to bind to tropomyosin in skeletal and cardiac muscle cells.

What is true about the cardiac muscle?

Contraction is triggered at nodes of conducting fibers.

Nuclei are centrally located.

Contraction is triggered at motor end plate.

Fibers are aligned in branching arrangements.

What is true about perimysium?

It surrounds a bundle of fibers

It surrounds the whole muscle

It contains blood vessels

It surrounds every single muscle fiber

It does not contain any blood vessels

What is true about sarcomeres?

Contains Z line + ½ I Band + A Band + ½ I Band + Z line.

Are typical for smooth muscles

Extends from Z line to Z line

Contains Z line + whole I band + A band + whole I band + Z line

Are present only in smooth muscles.

The major protein of the Z line of sarcomere is creatine kinase.

In smooth muscle sarcomeres are arranged in myofibrils

Extends from M line to M line

The major protein of the Z line of sarcomere is myosin

Which pairs are correct (cells/structures and their location)?

Caveolae - Smooth muscle

Intercalated discs - cardiac muscle

Smooth muscle cells - muscularis externa of small intestines

Two terminal cisterns per sarcomere with T-tubule - skeletal muscle
