Exam 8: Muscle Physiology

MATCHING: ART The following questions relate to accompanying figure of the three types of muscle tissue. Use the figure to help match the following characteristics with the correct muscle type. -Involuntary

Myosin

MATCHING Indicate which of the muscle proteins in skeletal muscle is associated with the item in question by writing the appropriate letters in the blanks using the answer code below: -Can bind with myosin during muscle contraction.

Indicate the characteristics of the muscle-tension receptors using the following answer code: -Coactivation by gamma motor neurons

Sequence the following events involved in muscle cell contraction

Oxidative phosphorylation occurs within the mitochondria of muscle cells.

Submaximal isometric contractions are important for

At Io, a muscle is maximally stretched so that it can develop the most tension upon contraction, because the thin filaments can slide in a maximal distance.

Match muscle type with correct characteristics. -single unit smooth muscle

Indicate the characteristics of the muscle-tension receptors using the following answer code: -Provides information to motor regions of the brain.

Summation events result from increasing amounts of cytoplasmic calcium levels.

Calcium that enters the cell during smooth muscle excitation binds with

Indicate which type of muscle is associated with the property in question by writing the appropriate letter in the blank using the answer code below: -Displays pacemaker potentials and slow-wave potentials.

A motor unit refers to

Match sarcomere component with correct characteristic. -Joins adjacent sarcomeres together.

Indicate which of the characteristics in question apply to each of the muscle fiber types by using the following answer code (more than one answer may apply): -Has myosin ATPase activity.

Indicate which of the characteristics in question apply to each of the muscle fiber types by using the following answer code (more than one answer may apply): -Produces the most lactic acid.

Smooth muscle is grouped into two categories, _____ and _______.

Tendons attach muscles to bones.

A motor unit is a single muscle plus all of the motor neurons that innervate it.
