What are 3 types of muscle tissue?
- A.
Cardiac, smooth, and striated
- B.
Smooth, involuntary, and involuntary
- C.
Cardiac, skeletal, and striated
Correct Answer
A. Cardiac, smooth, and striatedExplanation
The correct answer is cardiac, smooth, and striated. These three types of muscle tissue are differentiated based on their structure and function. Cardiac muscle tissue is found only in the heart and is responsible for pumping blood. Smooth muscle tissue is found in the walls of organs and blood vessels, and it helps in the movement of substances through these structures. Striated muscle tissue, also known as skeletal muscle tissue, is attached to bones and is responsible for voluntary movements of the body.Rate this question:

Muscles will shrink if they are not used.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Muscles require regular use and exercise to maintain their strength and size. When muscles are not used, they can undergo a process called atrophy, where the muscle fibers decrease in size and the overall muscle mass decreases. This can result in muscle weakness and loss of muscle tone. Therefore, it is true that muscles will shrink if they are not used.Rate this question:

The bicep and tripcep muscles are a muscle group that contract at the same time.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The bicep and tricep muscles are not a muscle group that contract at the same time. In fact, they are antagonist muscles, meaning that when one contracts, the other relaxes. The bicep muscle is responsible for flexing the elbow, while the tricep muscle is responsible for extending the elbow. Therefore, they work in opposition to each other rather than contracting simultaneously.Rate this question:

What is the functional unit of a muscle?
- A.
Nerve tissue
- B.
Sarcomere
- C.
Myofibril
- D.
Striated tissue
Correct Answer
B. SarcomereExplanation
The sarcomere is the functional unit of a muscle. It is a highly organized structure within a muscle fiber that is responsible for muscle contraction. It is composed of two types of protein filaments, actin and myosin, which slide past each other during contraction. This sliding filament mechanism allows for the shortening of the sarcomere and ultimately the muscle as a whole, resulting in movement. Therefore, the sarcomere plays a crucial role in the functioning of muscles.Rate this question:

A muscle can only partially contract.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Muscles have the ability to fully contract, not just partially. When a muscle contracts, the muscle fibers shorten, resulting in the movement of the body part it is attached to. This contraction can be either voluntary or involuntary. Therefore, the statement that a muscle can only partially contract is incorrect.Rate this question:

When a muscle receives a nerve impulse it contracts fully and then relaxes awaiting the next impulse. This is known as the ____ principle of muscle contraction.
- A.
"All or none"
- B.
Reflex
- C.
Knee jerk
Correct Answer
A. "All or none"Explanation
The principle of "All or none" in muscle contraction states that when a muscle receives a nerve impulse, it either contracts fully or does not contract at all. This means that there is no partial contraction of the muscle. Once the muscle receives the impulse, it contracts completely and then relaxes, waiting for the next impulse to contract again. This principle ensures that the muscle generates enough force to perform its function effectively.Rate this question:
