Understanding Skeletal Muscles Vocab 5

What is the involuntary muscle?

• Skeletal muscles that are under conscious control
• Muscles that only function during sleep
• Muscles that are exclusively found in the digestive system
• Involuntary muscles are muscles that operate without conscious control, including smooth and cardiac muscles.

What is the voluntary muscle?

• Cardiac muscle is primarily skeletal muscle.
• Voluntary muscle is a type of muscle that is under conscious control, primarily skeletal muscle.
• Smooth muscle is a type of voluntary muscle.
• Involuntary muscle is always under conscious control.

What is the primary function of skeletal muscles?

• Movement and posture

• Digestion

• Circulation

• Respiration

Which type of muscle fiber is designed for endurance and can sustain activity for long periods?

• Slow-twitch fibers

• Fast-twitch fibers

• Type IIa fibers

• Type IIb fibers

What is a characteristic of fast-twitch muscle fibers?

• They fatigue quickly

• They are rich in mitochondria

• They are ideal for long-distance running

• They provide energy through aerobic respiration

What is a tendon?

• A tendon is a fibrous connective tissue that connects muscle to bone.
• A tendon is a type of ligament.
• A tendon connects bone to bone.
• A tendon is a type of muscle tissue.

What is a straited muscle?

• Striated muscle is a type of muscle tissue that has a striped appearance and is responsible for voluntary movements.
• Striated muscle is a type of connective tissue that supports organs.
• Striated muscle is involuntary and controls automatic movements.
• Striated muscle is a type of smooth muscle found in the heart.

What is a smooth muscle?

• Smooth muscle is a type of skeletal muscle that is under conscious control.
• Smooth muscle is found only in the heart.
• Smooth muscle is a type of voluntary, striated muscle tissue.
• Smooth muscle is a type of involuntary, non-striated muscle tissue found in organs.

What is the cardiac muscle?

• Cardiac muscle is found in the arms and legs.
• Cardiac muscle is responsible for digestion.
• Cardiac muscle is a type of smooth muscle.
• Cardiac muscle is the muscle tissue of the heart that pumps blood.

What is muscle tissue?

• Muscle tissue is responsible for storing energy in the body.
• Muscle tissue is a specialized tissue that enables movement in the body.
• Muscle tissue is a type of connective tissue.
• Muscle tissue is primarily found in the brain and spinal cord.
