What is the definition of excitability (irritability) in muscle tissue?
Ability to shorten when stimulated.
Ability to receive and respond to a nerve impulse.
Ability to stretch without being damaged.
Ability to return to original length after being stretched.
What is the primary function of excitability in muscle tissue?
To produce tension and movement.
To prevent tearing and allow flexibility.
To enable communication between the brain and muscles.
To maintain shape and tone for repeated movements.
Which characteristic of muscle tissue describes its ability to shorten when stimulated?
Excitability
Extensibility
Elasticity
Contractibility
What is the main purpose of contractibility in muscles?
To allow muscles to return to their original length.
To prevent muscle damage during stretching.
To produce tension and movement.
To receive nerve impulses.
Which of the following is an example of contractibility in action?
Hamstrings stretching when bending forward.
Calf muscles returning to position after each step.
The heart muscle contracting to pump blood.
Muscles receiving a nerve impulse.
The ability of muscle tissue to stretch without being damaged is known as:
Contractibility
Elasticity
Excitability
Extensibility
What is the function of extensibility in muscle tissue?
To enable communication with the brain.
To produce force for movement.
To prevent tearing and allow flexibility.
To maintain muscle tone.
Which characteristic allows muscle tissue to return to its original length after being stretched or contracted?
Contractibility
Extensibility
Excitability
Elasticity
What is the definition of pressure in the context of the human body?
A twisting force around a joint.
The ability of tissue to stretch and recoil.
Force applied over an area.
A pulling or stretching force from muscle contraction.
Which of the following is an effect of pressure on the body?
Produces rotational movement.
Allows movement but can cause strain if excessive.
Prevents injury and stores energy.
Impacts blood flow, joint stress, and tissue health.
How is torque defined in relation to body mechanics?
A force that causes tissues to stretch.
A twisting or rotational force around a joint.
The result of balanced internal and external forces.
Force distributed evenly across a surface.
Which activity is an example of torque producing rotational movement?
Holding a plank position.
Tendons recoiling during jumping.
Pitching a baseball.
Wearing high heel shoes.
What is the primary characteristic of tension in muscles?
The ability to return to original shape after deformation.
A force that causes joints to compress.
A pulling or stretching force from muscle contraction.
The overall motion of the body.
What is a key benefit of tissue elasticity in the body?
It increases joint stress.
It generates excessive strain.
It prevents injury and stores energy.
It causes muscles to contract involuntarily.
What is the definition of movement in the context of the muscular system?
A twisting force applied to a joint.
The result of balanced internal and external forces.
The stretching of tendons beyond their normal range.
The compression of tissues due to external weight.
