Your Skeletal System Trivia Quiz

Answer: Production of bile

Your skeletal system shapes and supports your body, enables you to move, protects your organs, produces blood cells and stores minerals and other materials until your body needs them. It is your frame and provides your shape.

Answer: Joint

Joints allow bones to move in different ways. There are four types of joints: hinge, ball-and-socket, pivot, and gliding joints. Hinge joints allow forward or backward motion and are found in your knees and elbows. The ball-and-socket joint in your shoulder allows you to swing your arm freely in a circle. Pivot joints have two bones rotating around one another. One example is your neck. Gliding joints allow one bone to slide over another and are found in your wrists and ankles.

Answer: Ligaments

Ligaments are strong connective tissues. They hold bones and joints together and are made of fiber. The other type of connective tissue is known as cartilage. Cartilage is basically soft bone. One example of cartilage is the area above your nose.

Answer: False

Humans are born with around 300 bones. However, when you grow some of them merge together. When you are a fully and normally grown adult, you have 206 bones.

Answer: Compact Bone

Compact bone, also known as cortical bone, is underneath the outer membrane. It is hard and dense, but it is not solid. Small canals run through the compact bone, which carry blood vessels and nerves from the bone's surface to the living cells in the bone.

Answer: Ear

The smallest bones in your body are in your middle ear. They are a set of three bones called the ossicles. These bones help the sound in your ear vibrate.

Answer: Femur

Your femur is the scientific name for the thigh bone. It is the only bone in the thigh and is very strong; the strongest in your body. The femur is also the closest bone to the center of your body.

Answer: True

Exercising regularly helps keep your bones strong. This is because performing exercises such as running and lifting weighting gives your bones a workout.

Answer: Osteoporosis

Osteoporosis is a condition in which the body's bones become weak and break easily. This is more common in women. Evidence has suggested that exercise can help prevent osteoporosis.

Answer: Fracture

A fracture is a broken bone. There are two types of fracture: simple and compound. In a simple fracture, the bone is cracked or completely broken in two or more pieces. A compound fracture is when the broken ends of the bone protrude through the skin.

Answer: Dislocation

A dislocation occurs when the end of a bone, such as your shoulder, pops out of its joint. A dislocation is usually nothing major and a doctor can put back a dislocated bone. However, it might require surgery if it badly misplaced or occurs regularly.

Answer: Sprain

A sprain occurs when ligaments are stretched too far. Sprains are very common and often happen in the ankle when somebody accidentally stumbles. Sprains may cause swelling in the injured areas.

Answer: True

An x-ray is the most common way to identify bone injuries. X-rays are a form of energy that travels in waves. The waves pass through your body to identify bone injuries. MRI (magnetic resonance imaging) is useful to take clear images of both the bone and soft tissues.

However, MRIs are expensive to operate and use and are not as common as x-rays. A CT scan or CAT scan is somewhat similar to the x-ray. However, it can see the inside the body more clearly.

Answer: Arthritis

Arthritis is an injury or disease in the joints. It makes movement extremely painful. If movement becomes impossible, an artificial joint made of plastics or metals may be needed.

Answer: Arthroscope

An arthroscope is a slim, tube-shaped instrument. A small incision is made and it is inserted. Attached to it is a camera that projects an image from the inside of the joint. The camera display is on a monitor. It allows doctors to see inside the joint and to see what is wrong. Arthroscopes are used to identify many problems.
