12 FIT - Muscle Types, Fibers and Contractions LM6/7

Which of the following is not a type of muscle tissue?

• Skeletal

• Cardiac

• Smooth

• Connective

The muscle type responsible for voluntary movements is called (a)   muscle.

Cardiac muscle is found in which organ?

• Lungs

• Heart

• Liver

• Kidneys

The sensory receptors that provide information about joint angle, muscle length, and muscle tension are called (a)   .

Which type of muscle fiber is most resistant to fatigue?

• Type I (Slow-twitch)

• Type IIa (Fast-twitch oxidative)

• Type IIb (Fast-twitch glycolytic)

Arrange the following steps in the correct order for muscle contraction:

Which proprioceptor is responsible for detecting changes in muscle tension?

• Muscle spindle

• Golgi tendon organ

• Pacinian corpuscle

• Ruffini ending

A contraction where the muscle lengthens while producing force is called an (a)   contraction.

Which type of contraction involves no change in muscle length?

• Isotonic

• Isometric

• Eccentric

• Concentric

During a (a)   contraction, the muscle shortens while generating force.
