1.
What is the biggest bone in the human body?
Correct Answer
B. Femur
Explanation
The femur is the biggest bone in the human body. It is located in the thigh and is also known as the thigh bone. The femur is the longest and strongest bone in the body, responsible for supporting the weight of the body and facilitating movement. It connects the hip bone to the knee joint and plays a crucial role in walking, running, and other physical activities.
2.
The elbow and knee are what type of joints?
Correct Answer
B. Hinge
Explanation
The elbow and knee joints are classified as hinge joints because they allow movement in only one plane, similar to the opening and closing of a door on its hinges. These joints primarily allow flexion and extension movements, with a slight amount of rotation possible in some cases. The hinge joint design enables stability and strength in these weight-bearing joints, making them suitable for the specific functions of the elbow and knee.
3.
The ______________ connects bones to muscles, enabling movement when the muscle contracts.
Correct Answer
tendon, Tendon
Explanation
A tendon is a fibrous connective tissue that connects muscles to bones. When a muscle contracts, the tendon pulls on the bone, causing movement at the joint. This is a crucial part of the musculoskeletal system, allowing for mobility and stability.
4.
A joint is a place where two or more bones meet?
Correct Answer
A. True
Explanation
A joint is indeed a place where two or more bones meet. Joints allow for movement and provide flexibility in the skeletal system. They can be found throughout the body, such as the knee, elbow, and shoulder joints.
5.
What is the function of the skeletal system?
Correct Answer
D. All of the above
Explanation
The skeletal system has multiple functions. Firstly, it provides support to the body, helping it to maintain its shape and structure. Secondly, it works in conjunction with muscles to facilitate movement and mobility. Lastly, the skeletal system contributes to giving the body its overall shape. Therefore, the correct answer is "All of the above".
6.
Blood works with bones of the skeleton to make the body move.
*Extra credit* ____________________ works with the bones of the skeleton to make the body move?
Correct Answer
B. False
Explanation
Blood does not work with the bones of the skeleton to make the body move. The movement of the body is primarily controlled by the muscular system, as muscles contract and relax to produce movement. The skeletal system provides support and structure to the body, while blood is responsible for transporting oxygen, nutrients, hormones, and waste products throughout the body.
7.
The elbow is a gliding joint.
Correct Answer
B. False
Explanation
The elbow joint is not a gliding joint. It is a hinge joint that allows for flexion and extension movements. Gliding joints, also known as plane joints, allow for sliding or gliding movements between bones. The elbow joint consists of the humerus, ulna, and radius bones, which form a hinge-like structure that enables the bending and straightening of the arm. Therefore, the statement that the elbow is a gliding joint is incorrect.
8.
Where can you find a ball and socket joint in the human body?
Correct Answer
C. Both hip and shoulder
Explanation
A ball and socket joint is a type of joint that allows for a wide range of movement in multiple directions. The human body has two ball and socket joints, one in the hip and one in the shoulder. In the hip joint, the rounded head of the femur fits into the socket of the pelvis, allowing for movements such as rotation and flexion. In the shoulder joint, the rounded head of the humerus fits into the socket of the scapula, allowing for movements such as abduction and adduction. Therefore, both the hip and shoulder joints are examples of ball and socket joints in the human body.

10.
The patella is found in your skull.
*Extra Credit* The patella is what kind of joint? _____________________________
Correct Answer
B. False
Explanation
The patella, commonly known as the kneecap, is not found in the skull. It is a small, triangular bone located in front of the knee joint. It plays a crucial role in protecting the knee joint and providing leverage to the quadriceps muscles. Therefore, the given statement "The patella is found in your skull" is incorrect.
11.
**EXTRA CREDIT** Gliding joints are found where?
Correct Answer
D. All of the above
Explanation
Gliding joints are found in the ankle, wrist, and spine. Gliding joints allow bones to glide past each other in various directions, facilitating smooth movements. The ankle joint allows for up and down movements of the foot, the wrist joint enables side-to-side and up and down movements of the hand, and the spine has multiple gliding joints that allow for flexibility and movement in various directions. Therefore, the correct answer is "All of the above."
