The muscular system is an organ system in the body. It consists of ________, smooth and cardiac muscle. Its role is to help the body to move, maintain posture and circulate blood through the body.
skeletal
digestive
respiratory
nervous
Which of the following is NOT a type of muscle found in the muscular system?
Skeletal
Smooth
Cardiac
Nervous
What is one of the main roles of the muscular system?
To help the body to move, maintain posture and circulate blood through the body.
To produce hormones for the body.
To filter waste from the blood.
To transmit electrical signals throughout the body.
What is the main function of the Muscle Belly?
The Muscle Belly is the thick, central part of the muscle that contracts to produce movement.
It stores calcium for muscle contraction.
It connects muscles to bones.
It produces red blood cells.
What are Muscle Fibers?
Muscle Fibers are the individual contractile cells that make up the muscle.
Muscle Fibers are the bones that support the body.
Muscle Fibers are the nerves that transmit signals to the brain.
Muscle Fibers are the blood vessels that carry oxygen.
What is a Myofibril?
A Myofibril is a basic rod-like unit of a muscle cell responsible for muscle contraction.
A Myofibril is a type of connective tissue found in bones.
A Myofibril is a gland that secretes hormones in the endocrine system.
A Myofibril is a type of neuron found in the brain.
What is the function of a Tendon?
A Tendon connects muscle to bone and transmits the force generated by the muscle to move the bone.
A Tendon connects bone to bone and stabilizes joints.
A Tendon produces red blood cells in the body.
A Tendon stores minerals such as calcium and phosphorus.
What is a Ligament?
A Ligament is a fibrous connective tissue that connects bones to other bones at joints.
A Ligament is a type of muscle that moves bones.
A Ligament is a fluid found in the joints.
A Ligament is a bone that supports the body.
When we measure muscle girth, what do we need to locate?
Muscle Fibre
Muscle Belly
Myofibril
Blood vessels

What is the insertion in muscle attachment?
Where the muscle attaches to the stationary bone
Where the muscle attaches to the mobile bone
Where the tendon attaches to the skin
Where the bone attaches to another bone
Fill in the blank: __________ muscles are muscles which are not under our conscious control.
Involuntary

What are fast twitch muscle fibers?
Skeletal muscle fibers that contract quickly and powerfully, responsible for short, high-intensity bursts of activity such as sprinting, jumping, and weightlifting.
Skeletal muscle fibers that contract slowly and sustain contractions for extended periods.
Muscle fibers found only in the heart.
Muscle fibers responsible for digestion.
What are slow twitch muscle fibers?
Skeletal muscle fibers that contract quickly and powerfully.
Skeletal muscle cells that contract slowly but can sustain contractions for extended periods, responsible for endurance activities such as running, swimming, and cycling.
Muscle fibers found only in the heart.
Muscle fibers responsible for digestion.
Fill in the blank: Fast twitch muscle fibers are primarily responsible for short, high-intensity bursts of activity such as ________, jumping, and weightlifting.
sprinting
yoga
walking
meditation
