These are striated muscles:
- A.
Skeletal
- B.
Cardiac
- C.
Smooth
- D.
Both A & B
Correct Answer
D. Both A & BExplanation
Both skeletal and cardiac muscles are striated muscles. Skeletal muscles are attached to the bones and are responsible for voluntary movements. Cardiac muscles are found in the walls of the heart and are responsible for pumping blood. Smooth muscles, on the other hand, are not striated and are found in the walls of organs such as the stomach and intestines. They are responsible for involuntary movements. Therefore, the correct answer is both A (skeletal) and B (cardiac).Rate this question:

- B.
Smooth muscle tissue
- C.
Cardiac muscle tissue
- D.
All of the above
Correct Answer
B. Smooth muscle tissueExplanation
Smooth muscle tissue is located in the walls of hollow internal structures such as the stomach, blood vessels, and airways. Unlike skeletal muscle tissue, which is attached to bones and allows for voluntary movement, smooth muscle tissue is involuntary and contracts slowly and rhythmically. Cardiac muscle tissue, on the other hand, is only found in the heart and is responsible for its involuntary contractions. Therefore, the correct answer is smooth muscle tissue.Rate this question:

- A.
1 bone, moveable tendon
- B.
2 bones, moveable joint
- C.
4 bones, moveable ligament
Correct Answer
B. 2 bones, moveable jointExplanation
Skeletal muscles attach to two bones and have a moveable joint between them. This is because muscles work by pulling on bones to create movement. The joint allows for the bones to move in relation to each other, enabling the muscle to exert force and produce motion. Therefore, the answer "2 bones, moveable joint" accurately describes the attachment and movement of skeletal muscles.Rate this question:

- C.
Rotation
- D.
All of the above
Correct Answer
B. OriginExplanation
The muscle's attachment to the more stationary bone is called the origin. This is where the muscle originates from and provides a stable base for muscle contraction. The origin is typically located closer to the midline of the body and remains relatively fixed during movement.Rate this question:
-
- 15.
The muscle's ______________ is its attachment to the more movable bone.
- A.
Insertion
- B.
Extension
Correct Answer
A. InsertionExplanation
The muscle's "insertion" refers to its attachment to the more movable bone. This means that the muscle is connected to the bone in a way that allows it to move the bone when it contracts. The insertion point is usually located further away from the body's midline compared to the muscle's origin, which is its attachment to the less movable bone.Rate this question:
-
- 16.
What attach muscle to bones at both orgin and insertion sites?
Correct Answer
tendons
tendon
the tendonExplanation
Tendons attach muscles to bones at both the origin and insertion sites. They are tough, fibrous connective tissues that provide stability and transmit the force generated by the muscle to the bone, allowing movement. Tendons are responsible for transferring the contraction of the muscle to the bone, enabling the body to perform various movements and actions.Rate this question:

Tendon sheaths and bursae perform this function:
- A.
Attaching muscle to bone
- B.
Temperature regulation
- C.
Lubrication
Correct Answer
C. LubricationExplanation
Tendon sheaths and bursae are structures in the body that are responsible for lubricating joints and reducing friction between tendons, muscles, and bones. They contain synovial fluid, which acts as a lubricant and helps to reduce wear and tear on the joints during movement. This lubrication function is essential for smooth and pain-free movement of the muscles and bones.Rate this question:

For muscle contractions to occur, the body needs:
- A.
Tendons and joints
- B.
ATP and calcium
- C.
Mitochondria and X chromosones
- D.
Sodium and calcium
Correct Answer
B. ATP and calciumExplanation
Muscle contractions require ATP (adenosine triphosphate) and calcium. ATP is the main source of energy for muscle contractions, providing the necessary fuel for the muscle fibers to contract. Calcium plays a crucial role in the process by binding to proteins in the muscle fibers, allowing them to interact and generate force. Without ATP, the muscles would not have the energy to contract, and without calcium, the muscle fibers would not be able to generate force effectively. Therefore, both ATP and calcium are essential for muscle contractions to occur.Rate this question:

Muscles move bones by ____________________ on them.
- A.
Pushing
- B.
Pulling
Correct Answer
B. PullingExplanation
Muscles move bones by pulling on them. When muscles contract, they generate a pulling force that causes the bones to move. This pulling action is possible due to the arrangement of muscles and tendons, which are connective tissues that attach muscles to bones. As the muscle fibers contract, they shorten and exert a pulling force on the tendons, which in turn pull on the bones, resulting in movement.Rate this question:
-
- 22.
If a prime mover caused extension, the antagonist would cause _____________
- A.
Rotation
- B.
Flexion
- C.
Isometric contractions
Correct Answer
B. FlexionExplanation
If a prime mover caused extension, the antagonist would cause flexion. Flexion is the movement that decreases the angle between two body parts, typically in the sagittal plane. In this scenario, the prime mover is responsible for extending a joint, which means it is causing the angle between the body parts to increase. The antagonist muscle, which has an opposing action to the prime mover, would then cause flexion to decrease the angle and counteract the extension caused by the prime mover.Rate this question:

Muscle contractions causing shivering would produce _________________
Correct Answer
heatExplanation
Muscle contractions causing shivering would produce heat. When muscles contract rapidly during shivering, it generates heat as a byproduct. This heat is produced to help maintain the body's core temperature and prevent hypothermia. Shivering is a physiological response to cold temperatures or illness, and it is the body's way of generating internal heat to keep warm.Rate this question:
- 27.
_____________ muscle contractions don’t always produce movement
- A.
Isometric
- B.
Isotonic
- C.
Tetanic
Correct Answer
A. IsometricExplanation
Isometric muscle contractions don't always produce movement because they occur when the muscle is activated and generating force, but there is no change in the length of the muscle or movement at the joint. In other words, the muscle contracts but there is no visible movement. This type of contraction is commonly seen in activities like holding a heavy object in a fixed position or maintaining a static posture.Rate this question:

When muscles are constantly stimulated and the strength of muscle contractions decreases, it is known as
- A.
Oxgyen debt
- B.
Fatigue
- C.
Atrophy
- D.
Myalgia
Correct Answer
B. FatigueExplanation
Fatigue is the correct answer because when muscles are constantly stimulated, they can become tired and lose their strength to contract. This can happen due to a lack of oxygen and energy supply to the muscles, leading to a decrease in muscle performance. Fatigue is a common phenomenon that occurs after prolonged or intense physical activity, and it can also be caused by various medical conditions or lifestyle factors.Rate this question:

- 29.
Muscle contraction that produces movement of a joint.
- A.
Isotonic
- B.
Isometric
- C.
Abduction
- D.
Adduction
Correct Answer
A. IsotonicExplanation
Isotonic refers to a type of muscle contraction that produces movement of a joint. In an isotonic contraction, the muscle length changes as it contracts and moves a joint, resulting in visible movement. This is in contrast to an isometric contraction, where the muscle contracts but there is no movement of the joint. Abduction and adduction refer to movements of the limbs away from and towards the midline of the body, respectively, and are not directly related to muscle contractions.Rate this question:
