Musculoskeletal System Quiz Questions And Answers

The sternum is a flat bone that is located in the chest. It is commonly known as the breastbone and is positioned in the center of the chest, connecting the ribcage. The sternum plays a crucial role in protecting the heart, lungs, and major blood vessels.

The ilium is a bone of the pelvis. It is the largest and uppermost part of the hip bone, forming the prominence of the hip. It plays a crucial role in supporting the weight of the upper body and connecting the spine to the lower limbs.

The statement that all joints of the body are freely moveable is false. While many joints in the body are indeed freely moveable, there are also joints that have limited or no movement, such as the joints in the skull or the joints between the vertebrae in the spine. Additionally, some joints may become less mobile due to injury, disease, or age. Therefore, it is incorrect to say that all joints of the body are freely moveable.

The femur is the correct answer because it is the longest and strongest bone in the body. It is located in the thigh and is responsible for supporting the weight of the body and facilitating movement. The femur is also crucial for the attachment of muscles, making it an essential bone for mobility and stability.

The thoracic spine is not located in the neck. The thoracic spine refers to the middle and upper back region, consisting of twelve vertebrae that connect to the rib cage. The neck region is known as the cervical spine, which is located above the thoracic spine. Therefore, the statement that the thoracic spine is located in the neck is false.

When you shrug your shoulders, the bone that elevates is the scapula. The scapula, also known as the shoulder blade, is a flat, triangular bone located on the upper back. It is attached to the clavicle (collarbone) and the humerus (upper arm bone) and plays a key role in the movement of the shoulder joint. When you shrug, the scapula moves upward and inward, causing the shoulders to lift.

The number of thoracic vertebrae in the spine is twelve. The thoracic vertebrae are located in the middle region of the spine, between the cervical vertebrae in the neck and the lumbar vertebrae in the lower back. There are twelve thoracic vertebrae in total, each of which is connected to a pair of ribs. These vertebrae provide structural support and protection for the organs in the chest, such as the heart and lungs.

The humerus is the long bone located in the upper arm. It extends from the shoulder to the elbow, making the answer "shoulder to elbow" the best explanation for its location.

The trapezius muscle is located in the back. It is a large, triangular muscle that extends from the base of the skull down to the middle of the back and across the shoulder blades. It helps to move and stabilize the shoulder blades and is involved in various movements of the neck and upper back.

There are seven cervical vertebrae in the human spine. The cervical vertebrae are located in the neck region and are numbered C1 to C7. These vertebrae provide support and flexibility to the neck and allow for various movements of the head and neck.

There are five lumbar vertebrae in the human spine. The lumbar vertebrae are the largest and strongest of the movable vertebrae in the spine. They are located in the lower back region and play a crucial role in supporting the weight of the upper body and allowing for movement and flexibility.

The ulna is one of the two bones in the forearm, along with the radius. It runs parallel to the radius from the elbow to the wrist. The ulna is located on the side of the forearm opposite to the thumb, commonly known as the pinky side. Therefore, the answer "elbow to wrist (pinky side)" accurately describes the location of the ulna.

Joints connect bone to bone in the human body. Joints are the structures that allow movement between bones and provide stability to the skeletal system. They are formed by the combination of bones, ligaments, tendons, and cartilage. Joints enable various types of movements, such as bending, rotating, and extending, allowing us to perform a wide range of activities. Without joints, the skeletal system would be rigid and immobile.

The fibula is a bone located on the lateral side of the lower leg, extending from the knee to the ankle. It runs parallel to the tibia, which is the larger bone in the lower leg. The fibula does not bear as much weight as the tibia, but it provides support and stability to the leg. Therefore, the answer "Knee to ankle (lateral side)" accurately describes the location of the fibula.

The latissimus dorsi muscle is located in the back. It is a large, flat muscle that extends from the lower spine to the upper arm. It is responsible for various movements of the shoulder joint, such as pulling the arm down and back, rotating the shoulder inward, and bringing the arm closer to the body.
