Answer The Question Bone Structure Quiz

Cartilage is a type of connective tissue that is indeed more flexible than bone. It is a firm and flexible tissue that provides structure and support to various parts of the body, such as the nose, ears, and joints. Unlike bone, which is rigid and hard, cartilage is able to bend and absorb shock, making it more flexible. This flexibility allows it to withstand pressure and movement without breaking, making it an essential component in the body's skeletal system.

A joint is a place where two bones come together. It is the point of connection between two bones, allowing movement and providing stability to the skeletal system. Joints are essential for mobility and are found throughout the body. They can be classified into different types based on their structure and function, such as hinge joints, ball-and-socket joints, and pivot joints.

spongy bone is Strong, but lightweight because it has
many small spaces within it

The statement is true. As the body grows, the cartilage in the skeleton is gradually replaced by hard bone tissue. This process is known as ossification, and it is a natural part of skeletal development. Ossification helps to strengthen the skeleton and provide support for the growing body.

Cartilage is a type of connective tissue that covers the ends of many bones in the adult body. It acts as a cushion and reduces friction between bones, allowing for smooth movement and flexibility. This is particularly important in joints, where the ends of bones come into contact with each other. Therefore, the statement "Cartilage covers the ends of many bones in the body of an adult" is true.

Osteoporosis is a condition characterized by weak and brittle bones that are prone to fractures. It is not the same as arthritis, which refers to inflammation of the joints. Osteoarthritis is a specific type of arthritis that occurs when the protective cartilage on the ends of bones wears down over time. Rheumatoid arthritis, on the other hand, is an autoimmune disease that causes chronic inflammation in the joints. Therefore, the correct answer is osteoporosis.

Cartilage is a flexible connective tissue that covers the ends of bones in a joint. It acts as a cushion and prevents the bones from rubbing against each other, reducing friction and allowing smooth movement.

Ligaments are the connective tissues that hold bones together. They are strong, fibrous bands that connect bones to other bones, providing stability and allowing for movement at the joints. Unlike tendons, which connect muscles to bones, ligaments specifically function to hold bones in place and prevent excessive movement or dislocation. Therefore, ligaments are the correct answer to the question.

The statement is false because much of an infant's skeleton is actually made up of cartilage, not bone. As infants grow and develop, the cartilage gradually ossifies and turns into bone. Therefore, at birth, a significant portion of an infant's skeleton is still cartilaginous.

The skull is the correct answer because it is made up of several bones that are fused together and form a rigid structure that protects the brain. These bones do not move independently and therefore can be considered immoveable joints. The mouth, elbow, and hinge are all examples of moveable joints, while "none of the above" is incorrect as the skull does have immoveable joints.

the outer membrane is where blood vessels and nerves enter and leave the bone.

The statement is false. Cartilage does not completely turn into bone as the body stops growing. Some cartilage remains in certain parts of the body, such as the nose and ears, even after growth stops. Additionally, cartilage continues to play a role in the body, providing cushioning and flexibility in joints.

Selective breeding is the process of intentionally choosing certain organisms with desired traits to reproduce and serve as parents for the next generation. This allows for the propagation of those desired traits in subsequent generations, leading to the development of new varieties or breeds with specific characteristics. It involves carefully selecting and mating individuals that possess the desired traits, such as higher yield in crops or specific physical traits in animals, in order to amplify and perpetuate those traits in future generations.

bone marrow is Soft connective tissue in the spaces in bone

compact bone is small canals with blood vessels running through

The given answer states that bones are very strong and lightweight. This is true because bones have a unique combination of strength and lightness, allowing them to support the body's weight and withstand forces without breaking. This is essential for the skeletal system to provide structural support and protect vital organs.

The correct answer is A and B. This is because statement B states that when a bone breaks and heals, the bone may be stronger, which is true. Statement A also states that calcium and phosphorus are two major minerals in bone, which is also true. Therefore, both statements A and B are true.

A hinge joint is a type of joint that allows for forward/backward motion. It is found in the knee and elbow. This type of joint allows for flexion and extension movements, enabling the joint to open and close like a hinge.

The two types of joints are movable and immovable. Movable joints allow for a wide range of motion and are found in areas such as the knees, elbows, and shoulders. Immovable joints, on the other hand, do not allow for any movement and are found in areas such as the skull. Both types of joints play important roles in the body's structure and function.

Bones have multiple functions in the body. Firstly, they provide shape and support to the body, giving it structure and allowing it to maintain its form. Secondly, bones are responsible for movement, as they serve as attachment points for muscles and allow for joint movement. Thirdly, bones protect vital organs, such as the skull protecting the brain or the ribcage protecting the heart and lungs. Additionally, bones play a role in hematopoiesis, which is the production of blood cells. Lastly, bones store minerals, such as calcium and phosphorus, which are important for various bodily functions.

A pivot joint is a type of joint that allows one bone to rotate around another bone. In the case of the head and neck, this joint allows the movement of the head as it rotates on top of the neck.

A gliding joint is found in the wrist or ankle where one bone slides over another.

Osteoporosis is a condition where bones lose minerals and become weaker. To prevent osteoporosis, it is important to eat foods that are rich in calcium and phosphorus. These nutrients are essential for maintaining strong and healthy bones. By consuming a diet that includes sources of calcium and phosphorus, such as dairy products, leafy green vegetables, and nuts, individuals can help to prevent the loss of minerals from their bones and reduce the risk of osteoporosis.

A ball/socket joint is found in the shoulder (arms) and hips (legs) and allows for a swivel motion in a circle.
