LESSON 7: 20 QUESTIONS REVIEWER

Skeletal muscle

Skeletal muscle

Which of the following types of muscle is responsible for voluntary movements in the body?

Quadriceps

2. Which muscle group is essential for activities such as walking, running, and jumping?

Tendons

What connects your muscles to bones? It also helps us move our limbs and they prevent muscle injury by absorbing some of the impact your muscles take when you do activities or other movements.

Deltoid

It is a muscle that is located in the shoulder  and responsible for various arm movements. Including lifting the arm away from the body.

Myosin and Actin

What is the most abundant protein found in a human’s muscle?

Hamstrings

It is found in the back of the thigh, and it is responsible for bending the knee and hip extension.

Quadriceps

It is located in the front of the thigh.

Myosin

Which protein, found in skeletal muscle fibers, is responsible for the sliding filament theory of muscle contraction by interacting with actin to generate force?

Skeletal muscle

Which type of muscle tissue is under voluntary control?

ATP (Adenosine triphosphate)

What molecule provides the immediate energy for muscle contraction?

Produces movement by contracting and relaxing muscles.

What is the primary function of the muscular system?

Acetylcholine

What is the name of the neurotransmitter responsible for initiating muscle contraction at the neuromuscular junction?

Quadriceps

 Located in the front of the thigh. It is crucial for activities like walking, running and jumping

 Perimysium

 Also called "interfascicular connective tissue, a tissue sheath that surrounds individual muscle fascicles

 Biceps Brachii

Found in the upper arm, the biceps brachii is responsible for flexing the elbow and supinating the forearm.

Intramuscular Injections (IM)

A technique used to deliver a medication deep into the muscles.

The muscle is unable to contract, even when stimulated.

What happens to a muscle during muscle fatigue?

 Muscle Fatigue

Occurs when a muscle is unable to contract, even when it's being stimulated.

ATP ( adenosine triphosphate)

The energy source for muscle contractions is:

Elasticity
