Muscle Tissue and Function Concepts

Front

What is the primary function of the Pectoralis Major muscle?

Back

The Pectoralis Major muscle is primarily responsible for the movement of the shoulder joint, including flexion, adduction, and internal rotation of the arm.

Front

What type of muscle tissue is responsible for involuntary movements such as peristalsis?

Back

Smooth Muscle Tissue is responsible for involuntary movements, including peristalsis, which is the contraction of muscles in the digestive tract.

Front

Which type of muscle tissue is responsible for generating body heat during physical activity?

Back

Skeletal Muscle Tissue generates body heat through the process of metabolism during physical activity.

Front

What does the term 'Extensibility' refer to in muscle tissue?

Back

Extensibility refers to the ability of muscle tissue to be stretched without being damaged.

Front

What is the role of the External Obliques muscle?

Back

The External Obliques muscle aids in the rotation and lateral flexion of the trunk, as well as assisting in the compression of the abdominal cavity.

Front

What is the main characteristic of Cardiac Muscle Tissue?

Back

Cardiac Muscle Tissue is striated and involuntary, found only in the heart, and is responsible for pumping blood throughout the body.

Front

Define 'Contractility' in the context of muscle tissue.

Back

Contractility is the ability of muscle tissue to shorten and generate force when stimulated.

Front

What is the difference between Skeletal Muscle Tissue and Smooth Muscle Tissue?

Back

Skeletal Muscle Tissue is striated and under voluntary control, while Smooth Muscle Tissue is non-striated and under involuntary control.

Front

What is the significance of muscle tissue's 'Excitability'?

Back

Excitability refers to the ability of muscle tissue to respond to stimuli, such as nerve impulses, leading to contraction.

Front

How does the structure of Skeletal Muscle Tissue facilitate its function?

Back

The structure of Skeletal Muscle Tissue, with its long, cylindrical fibers and striations, allows for powerful and rapid contractions.
