Muscular System Test

Front

Which muscle type is striated?

Back

Cardiac and skeletal muscles are striated, meaning they have a banded appearance due to the arrangement of actin and myosin filaments.

Front

What separates neighboring muscles and groups?

Back

Fascia is a connective tissue that separates neighboring muscles and groups, providing support and structure.

Front

What type of contraction occurs when the muscle lengthens?

Back

Isotonic eccentric contraction occurs when a muscle lengthens while under tension, such as when lowering a weight.

Front

What is a rope-like fibrous connective tissue that connects muscles to bones?

Back

Tendons are the fibrous connective tissues that attach muscles to bones, allowing for movement.

Front

What is the 'kissing muscle'?

Back

The orbicularis oris is known as the 'kissing muscle' because it encircles the mouth and is used in actions like kissing.

Front

What type of muscle is involuntary and found in the heart?

Back

Cardiac muscle is involuntary and is found only in the heart, responsible for pumping blood.

Front

What is the function of skeletal muscles?

Back

Skeletal muscles are responsible for voluntary movements of the body, allowing for locomotion and posture.

Front

What connective tissue surrounds individual muscle fibers?

Back

Endomysium is the connective tissue that surrounds individual muscle fibers, providing support and insulation.

Front

What is the role of the perimysium?

Back

Perimysium is the connective tissue that surrounds fascicles, which are groups of muscle fibers, providing structure and support.

Front

What is an example of an isotonic concentric contraction?

Back

An example of isotonic concentric contraction is lifting a weight, where the muscle shortens while generating force.
