3.

The ribs, sternum, and spine protect these.
- Kidneys, bladder, urethra
- Heart, lungs, blood vessels
- Small intestine, large intestine
- Stomach, lungs
Correct Answer

A. Heart, lungs, blood vessels

Explanation

The correct answer is heart, lungs, blood vessels. The ribs, sternum, and spine form the ribcage, which provides protection for the heart, lungs, and blood vessels. The heart is a vital organ that pumps blood throughout the body, while the lungs are responsible for oxygenating the blood and removing carbon dioxide. The blood vessels, including arteries and veins, transport the blood to and from the heart and lungs. The ribs, sternum, and spine act as a barrier, shielding these essential organs and ensuring their proper functioning.

What do bones store?
- Bile and insulin
- Urine and feces
- Calcium and iron
- Nutrients
Correct Answer

A. Calcium and iron

Explanation

Bones store calcium and iron. Calcium is an essential mineral that is stored in bones and plays a crucial role in maintaining bone strength and density. It is also involved in muscle contraction, nerve function, and blood clotting. Iron is another important mineral that is stored in bones and is necessary for the production of red blood cells and the transportation of oxygen throughout the body. Both calcium and iron are vital for overall health and proper functioning of the body.

5.

What protects the spinal cord?
- Patella
- Ulna
- Vertebrae
- None of the above
Correct Answer

A. Vertebrae

Explanation

The spinal cord is protected by the vertebrae. The vertebrae are the bones that make up the spinal column and surround and encase the spinal cord. They provide a bony barrier that helps to shield the delicate spinal cord from injury or damage. The vertebrae also provide support and stability to the spine, allowing for movement and flexibility while still ensuring the protection of the spinal cord.

6.

The part of the bone where blood cells are made.
- Marrow
- Joint
- Ligament
- All of the above
Correct Answer

A. Marrow

Explanation

Marrow is the correct answer because it is the part of the bone where blood cells are made. Marrow is a soft, gelatinous substance found in the center of bones and is responsible for producing red and white blood cells as well as platelets. Joints and ligaments are not involved in the production of blood cells. Therefore, the correct answer is marrow.

What do the carpals and tarsals protect?
- Wrist and ankle
- Knee and elbow
- Heart, lungs, and blood vessels
- None of the above
Correct Answer

A. Wrist and ankle

Explanation

The carpals and tarsals are bones found in the wrist and ankle respectively. They form the structure of these joints and provide support and stability. Additionally, they protect the delicate structures within the wrist and ankle, such as nerves, blood vessels, and tendons, from injury and damage.

8.

What do the clavicle and scapula protect?
- Brain
- Intestines
- Shoulder
- Mind
Correct Answer

A. Shoulder

Explanation

The clavicle and scapula are bones located in the shoulder region. They form the shoulder girdle and provide support and protection to the shoulder joint and surrounding structures, such as the muscles, tendons, and ligaments. Therefore, the clavicle and scapula protect the shoulder.

9.

What do the ilium and spine protect?
- Digestive organs
- Knee and elbow
- Wrist and ankle
- None of the above
Correct Answer

A. Digestive organs

Explanation

The ilium and spine protect the digestive organs. The ilium is a bone in the pelvis that helps protect the lower part of the digestive system, including the intestines. The spine, or vertebral column, surrounds and protects the spinal cord, which is a crucial part of the central nervous system that controls various bodily functions, including digestion. Therefore, the ilium and spine play a significant role in safeguarding the digestive organs.

Which of these is NOT a job of the skeletal system?
- Support and give shape to the body
- Makes blood cells
- Removes wastes from the body
- None of the above
Correct Answer

A. Removes wastes from the body

Explanation

The skeletal system is responsible for supporting and giving shape to the body, as well as protecting internal organs and providing attachment points for muscles. It also produces blood cells in the bone marrow. However, the removal of wastes from the body is primarily the function of the excretory system, which includes organs like the kidneys, bladder, and skin. Therefore, removing wastes from the body is not a job of the skeletal system.

The ________ connect bones to muscles.
- Joints
- Tendons
- Ligaments
- Spine
Correct Answer

A. Tendons

Explanation

The tendons connect bones to muscles. Tendons are strong, fibrous connective tissues that transmit the force generated by muscles to the bones, allowing for movement of the joints. They are essential for the functioning of the musculoskeletal system in the human body.

These joints are found in the hip and shoulder.
- Hinge
- Ball and socket
- Pivot
- Saddle
Correct Answer

A. Ball and socket

Explanation

Ball and socket joints are found in the hip and shoulder. These joints allow for a wide range of motion in multiple directions, including flexion, extension, abduction, adduction, and rotation. The ball-shaped end of one bone fits into the cup-shaped socket of another bone, allowing for smooth and fluid movement. This type of joint provides stability and support while also allowing for a greater range of motion compared to other types of joints.

What do the patella and ulna protect?
- Wrist and elbow
- Digestive organs
- Knee and elbow
- Respiratory organs
Correct Answer

A. Knee and elbow

Explanation

The patella and ulna are both bones in the human body that provide protection to specific joints. The patella, also known as the kneecap, protects the knee joint. It acts as a shield, covering and protecting the front of the knee joint, preventing any direct impact or injury to the knee joint. The ulna, on the other hand, is one of the two bones in the forearm and it protects the elbow joint. It forms the bony prominence on the inner side of the elbow and provides stability and protection to the joint.

What do blood hormones help control?
- Blood sugar and fat deposits
- Proteins and carbohydrates
- Vitamins and fiber
- Proteins and nutrients
Correct Answer

A. Blood sugar and fat deposits

Explanation

Blood hormones help control blood sugar and fat deposits. Hormones such as insulin and glucagon regulate the level of glucose in the blood, ensuring it stays within a normal range. Insulin promotes the uptake of glucose into cells, while glucagon stimulates the release of stored glucose when blood sugar levels are low. Additionally, hormones like leptin and adiponectin regulate fat metabolism, helping to control the storage and breakdown of fat deposits in the body.

15.

These joints are found in the knee and elbow.
- Pivot
- Ball and socket
- Hinge
- None of the above
Correct Answer

A. Hinge

Explanation

The joints found in the knee and elbow are hinge joints. Hinge joints allow movement in only one direction, similar to the opening and closing of a door. In the knee and elbow, these hinge joints allow for flexion and extension, enabling the bending and straightening of the limbs. Pivot joints, on the other hand, allow for rotational movement, while ball and socket joints provide a wide range of motion in multiple directions. None of these descriptions fit the joints found in the knee and elbow, making hinge the correct answer.
