Loss of muscle mass and strength.
-
Any break in the continuity of a bone.
-
Straightening of a joint.
Correct Answer
A. Loss of muscle mass and strength.Explanation
Atrophy refers to the loss of muscle mass and strength. It occurs when muscles are not used or exercised regularly, leading to a decrease in muscle size and function. This can happen due to various reasons such as lack of physical activity, aging, or certain medical conditions. Atrophy can result in weakness, decreased mobility, and difficulties in performing everyday tasks. Regular exercise and physical therapy are often recommended to prevent or reverse muscle atrophy.Rate this question:

A person with osteoporosis usually develops gnarled fingers and visibly swollen joints.
-
True
-
False
Correct Answer
A. FalseExplanation
Osteoporosis is a condition characterized by weak and brittle bones, not by gnarled fingers and visibly swollen joints. The symptoms of osteoporosis typically include back pain, loss of height, and a stooped posture. Swollen joints and gnarled fingers are more commonly associated with conditions like rheumatoid arthritis or osteoarthritis. Therefore, the statement that a person with osteoporosis usually develops gnarled fingers and visibly swollen joints is incorrect.Rate this question:

A typical long bone consists of five basic parts, the blood vessels, the spongy bone, the marrow cavity, yellow marrow, and the _________.
Correct Answer
hard boneExplanation
A typical long bone consists of five basic parts, including the blood vessels, the spongy bone, the marrow cavity, yellow marrow, and the hard bone. The hard bone refers to the dense outer layer of the bone, also known as compact bone. This layer provides strength and support to the bone, protecting the inner structures and allowing for movement and weight-bearing.Rate this question:

There are about ______ muscles in our body.
Correct Answer
700Explanation
The human body consists of approximately 700 muscles. Muscles are responsible for various functions such as movement, stability, and heat production. They are made up of muscle fibers and are attached to bones by tendons. These muscles allow us to perform voluntary movements such as walking, running, and lifting objects. Additionally, muscles in our body also help in maintaining posture and providing support to our skeletal system. Overall, the human body contains around 700 muscles that play a crucial role in our daily activities.Rate this question:

A disorder characterized by interrupted nerve impulses from the brain that results in muscle weakness is know as __________.
Correct Answer
myasthenia gravisExplanation
Myasthenia gravis is a disorder that is characterized by interrupted nerve impulses from the brain, leading to muscle weakness. This condition occurs when there is a breakdown in communication between the nerves and muscles, resulting in fatigue and weakness in the affected muscles. The interruption of nerve impulses can cause difficulty in controlling voluntary muscles, such as those used for movement and breathing. Myasthenia gravis is an autoimmune disorder, meaning that the body's immune system mistakenly attacks its own tissues, in this case, the receptors on the muscles responsible for receiving nerve signals.Rate this question:

The muscle that forms the heart and is responsible for the beating is _______________.
Correct Answer
cardiac
cardiac muscleExplanation
The correct answer is "cardiac" or "cardiac muscle". The heart is made up of cardiac muscle, which is a specialized type of muscle tissue. This muscle is responsible for the rhythmic contractions and relaxations that allow the heart to beat and pump blood throughout the body. It is unique to the heart and different from skeletal or smooth muscle found in other parts of the body.Rate this question:

______________ is the only voluntary muscle associated with the skeletal system.
Correct Answer
skeletal
skeletal muscleExplanation
The skeletal muscle is the only voluntary muscle associated with the skeletal system. This is because the skeletal muscle is attached to the bones and is responsible for the movement of the body. Unlike other types of muscles, such as smooth muscles or cardiac muscles, the skeletal muscle is under conscious control, meaning that we can choose to contract or relax these muscles at will. This allows us to perform various movements, such as walking, running, or lifting objects.Rate this question:

Muscle fibers are held together by connective tissues.
-
True
-
False
Correct Answer
A. TrueExplanation
Muscle fibers are indeed held together by connective tissues. Connective tissues, such as tendons and fascia, provide structural support and help to transmit forces generated by muscle contractions. These tissues also allow for the coordination and synchronization of muscle movements, ensuring efficient and smooth functioning of the muscles. Therefore, the statement "Muscle fibers are held together by connective tissues" is true.Rate this question:
