What is the study of the muscular system?

• Kinesiology
• Myology
• Physiology
• Anatomy

What are the three Kinds of Muscle tissue?

• Tendons
• Ligaments
• Cartilage
• Skeletal muscle, Cardiac muscle, Smooth muscle

What are muscle functions?

• Muscle functions are limited to producing sound and speech.
• Muscle functions are solely for breathing and circulation.
• Movement, stability, control of openings, heat production, and glycemic control.

• Muscle functions include digestion and nutrient absorption.

In glycemic control

• Managing insulin production in the pancreas.
• Regulating blood pressure in hypertension.
• Muscles absorb the storage glucose which helps regulate blood sugar concentration.

• Monitoring cholesterol levels in heart disease.

What is fusiform Muscle?

• Fusiform muscle is a type of muscle that is flat and broad, providing stability but limited movement.
• Fusiform muscle is a type of muscle that is circular in shape, primarily used for posture.
• Fusiform muscle is a type of muscle that is triangular, mainly found in the heart.
• Thick in the middle and tapered at each end.

Uniform width and parallel fascicles?

• Parallel muscles .

• Irregular width and parallel fascicles
• Circular fascicular arrangement
• Random muscle fiber arrangement

What mucles are broad at one end and narrow at the other?

• Parallel muscles
• Circular muscles
• Triangular (Convergent Muscles)

• Fusiform muscles

What does it mean that a muscle exhibits excitability? 

• A muscle exhibits excitability when it only contracts without electrical signals.
• A muscle exhibits excitability to chemical signals, stretch, and electrical changes across the plasma membrane

• A muscle exhibits excitability when it is relaxed and inactive.
• A muscle exhibits excitability when it cannot respond to stimuli.

What does it mean that a muscle exhibits Conductivity?

• A muscle exhibits conductivity; local electrical change triggers a wave of excitation that travels along the muscle fiber

• A muscle exhibits conductivity when it can store energy for later use.
• A muscle exhibits conductivity when it can change its length without any electrical signals.
• A muscle exhibits conductivity when it can only contract without any coordination.

What does it mean that a muscle exhibits Contractility?

• A muscle exhibits contractility when it can stretch without generating any force.
• A muscle exhibits contractility when it can only relax and not generate force.
• A muscle exhibits contractility shorten when stimulated

• A muscle exhibits contractility when it can generate force but not shorten.
