The part of the bone where blood cells are made.
-
Joint
-
Marrow
-
Ligament
Correct Answer
A. MarrowExplanation
Marrow is the soft, spongy tissue found inside the bones. It is responsible for producing blood cells, including red blood cells, white blood cells, and platelets. This process is known as hematopoiesis. Marrow contains stem cells that differentiate into various types of blood cells. Therefore, the statement "The part of the bone where blood cells are made" accurately describes marrow. Joints are the connections between bones, and ligaments are bands of fibrous tissue that connect bones to each other.Rate this question:

What makes up the skeletal system?
-
blood
-
Muscles
-
Tissues
-
Bones
Correct Answer
A. BonesExplanation
The skeletal system is made up of bones. Bones provide support, shape, and protection to the body, as well as serving as attachment points for muscles. They also produce blood cells and store minerals such as calcium. Without bones, the body would not have a framework to support itself or be able to perform essential functions like movement and protection of vital organs.Rate this question:

What makes bones so strong?
-
Cartilage
-
Silica
-
Blood and marrow
-
Calcium and phosphorous
Correct Answer
A. Calcium and phosphorousExplanation
Bones are strong due to the presence of calcium and phosphorous. These minerals are essential for the formation and maintenance of bone tissue. Calcium provides the strength and rigidity to the bones, while phosphorous helps in the formation of the bone matrix. Together, they contribute to the overall strength and structure of the bones, making them able to withstand physical stress and support the body.Rate this question:

What works with the bones of your skeleton to make your body move?
-
Blood
-
Muscles
-
Tissues
-
Organs
Correct Answer
A. MusclesExplanation
Muscles work with the bones of your skeleton to make your body move. Muscles are responsible for generating force and contraction, which allows movement to occur. When muscles contract, they pull on the bones, causing them to move. This coordinated action between muscles and bones enables various movements, such as walking, running, and lifting objects. Without muscles, the bones would be unable to move, resulting in immobility.Rate this question:

What is a joint?
-
A hinge
-
A ball and socket
-
The place where two bones are joined
-
The place where tendons are fastened together
Correct Answer
A. The place where two bones are joinedExplanation
A joint refers to the place where two bones are joined together. It is the point of connection between two bones in the body, allowing for movement and flexibility. Joints can be found throughout the body and come in different forms, such as hinge joints (allowing movement in one direction, like the elbow) and ball and socket joints (allowing movement in multiple directions, like the hip). The correct answer accurately describes the definition of a joint as the place where two bones are joined.Rate this question:

Movable joints are places where bones can move easily. Which is an example of a movable joint?
-
Skull
-
ribs
-
Knee
Correct Answer
A. KneeExplanation
The knee is an example of a movable joint because it allows for a wide range of movement. It is a hinge joint that allows for flexion and extension, as well as some rotation. The skull and ribs, on the other hand, are examples of fixed joints as they do not allow for much movement.Rate this question:

Which of the following is an example of an immovable joint?
-
Skull
-
Ribs
-
Knee
Correct Answer
A. SkullExplanation
The skull is an example of an immovable joint because it is made up of several bones that are fused together, forming a solid structure. These bones do not have any movement between them, resulting in the skull being a fixed and immovable part of the body. Unlike the knee joint, which is a hinge joint allowing movement, or the ribs, which are connected to the spine by cartilage and allow some flexibility, the skull remains stationary and provides protection for the brain.Rate this question:

-
Option 4
-
All of the above
Correct Answer
A. All of the aboveExplanation
The skeletal system has multiple functions. It provides support to the body, giving it shape and structure. It also works in conjunction with the muscles to facilitate movement of the body. Therefore, the correct answer is "all of the above" as it encompasses all the mentioned functions of the skeletal system.Rate this question:

What is the difference between cartilage and bone?
-
Bone is rubbery, and cartilage is firm.
-
Cartilage is rubbery, and bone is firm.
-
Bone is a more primitive tissue than cartilage.
-
Bone is inside the body, and cartilage is outside.
Correct Answer
A. Cartilage is rubbery, and bone is firm.Explanation
Cartilage and bone have different textures. Cartilage is described as rubbery, while bone is described as firm. This difference in texture is due to the composition and structure of these tissues. Cartilage is made up of cells called chondrocytes and a matrix of collagen fibers, which give it its rubbery texture. On the other hand, bone is composed of cells called osteocytes and a matrix of collagen fibers and calcium minerals, which provide strength and rigidity, resulting in a firm texture.Rate this question:

These joints are found in the hip and shoulder.
-
Hinge
-
Ball and socket
-
Pivot
Correct Answer
A. Ball and socketExplanation
Ball and socket joints are found in the hip and shoulder. These joints allow for a wide range of motion in multiple directions, making them highly flexible. The rounded end of one bone fits into the cup-shaped socket of another bone, allowing for rotation and movement in multiple planes. This design allows for movements such as swinging the arm or rotating the leg, providing a greater range of motion compared to hinge or pivot joints.Rate this question:

What do the patella and ulna protect?
-
Wrist and elbow
-
Digestive organs
-
Knee and elbow
Correct Answer
A. Knee and elbowExplanation
The patella is a bone located in the knee joint that protects the knee from external impact and provides stability to the joint. The ulna is one of the two bones in the forearm that forms the elbow joint and helps protect the structures within the joint. Therefore, both the patella and ulna protect the knee and elbow respectively.Rate this question:

There are three types of joints. What are they?
-
Immovable, stable, movable
-
Immobile, mobile, stable
-
immovable, movable, partly movable
Correct Answer
A. immovable, movable, partly movableExplanation
The correct answer is immovable, movable, partly movable. Joints in the human body can be classified into three types based on their movement capabilities. Immovable joints, also known as fixed or synarthrosis joints, do not allow any movement. Movable joints, also called synovial or diarthrosis joints, allow a wide range of movements. Partly movable joints, also known as amphiarthrosis joints, allow limited movement. This classification helps in understanding the different functions and capabilities of joints in the body.Rate this question:

These joints are found in the wrists and ankles
-
Ball ans Socket
-
Hinge
-
Gliding
Correct Answer
A. GlidingExplanation
Gliding joints are found in the wrists and ankles. These joints allow bones to slide past each other in multiple directions, providing flexibility and allowing for smooth movements. Unlike ball and socket joints, which allow for a wide range of motion, or hinge joints, which only allow for movement in one plane, gliding joints allow for limited movement in multiple directions. This type of joint is well-suited for the wrists and ankles, as they require both stability and flexibility for everyday movements.Rate this question:

Partly movable joints are places where bones can move a little. Which is an example of a partly movable joint?
-
Skull
-
Elbow joint
-
rib
-
Knee joint
Correct Answer
A. ribExplanation
A rib is an example of a partly movable joint because it is connected to the spine at the back and to the sternum at the front by cartilage. This allows for a small amount of movement, such as during breathing or bending of the torso. However, the movement is limited compared to fully movable joints like the elbow or knee joint.Rate this question:

What is the difference between compact bone and spongy bone?
-
They have different bone marrow.
-
They are made of different materials.
-
They have different sizes of bone cells.
-
They have different arrangement of bone cells.
Correct Answer
A. They have different arrangement of bone cells.Explanation
Compact bone and spongy bone differ in their arrangement of bone cells. Compact bone has a dense and solid structure with tightly packed bone cells arranged in concentric circles around blood vessels, forming osteons. On the other hand, spongy bone has a more porous and honeycomb-like structure with a network of trabeculae. The bone cells in spongy bone are not arranged in concentric circles but are scattered within the trabeculae. This difference in arrangement of bone cells allows compact bone to provide strength and support, while spongy bone provides flexibility and helps in reducing the weight of the bone.Rate this question:
