1.

What term is used to describe each end of a long bone?

Epiphysis

Diaphysis

Medullary cavity

Periosteum

2.

In the context of the skeletal system, identify an accurate statement about the movement classification of joints.

Flexion occurs when a joint is straightened, and the angle between the involved bones increases.

The act of moving a body part away from the midline of the body is known as adduction.

The act of turning the sole of one foot inward in such a way that it points to the other foot is known as inversion.

Pronation occurs when the hand is turned to the point where the palm faces upward.

3.

Identify a difference between compact bone tissue and spongy bone tissue.

Spongy bone tissue forms the shafts of long bones, whereas compact bone tissue forms the ends of long bones.

Compact bone tissue is made up of bars and plate-like units called trabeculae, whereas spongy bone tissue is made up of cylindrical-shaped units called osteons.

Compact bone tissue has a dense, strong structure, whereas spongy bone tissue has a light, porous structure.

Spongy bone tissue tends to add to the overall bone weight, whereas compact bone tissue helps make bones lighter in weight.

Incorrect :

Compact bone tissue has a dense, strong structure, whereas spongy bone tissue has a light, porous structure. Spongy bone tissue is made up of bar and plate-like units called trabeculae,

4.

Which of the following is an example of a smooth muscle?

The biceps

The heart muscle

The stomach muscle

The triceps

5.

Identify an accurate statement about the different types of muscles in the human body.

Smooth muscles are the muscles responsible for causing the heart to contract and relax.

Skeletal muscles are the muscles responsible for facilitating the movement of air through the airways of the lungs.

Cardiac muscles are found within all organs, airways, and blood vessels in the body.

Smooth muscles are involuntary muscles; they cannot be consciously controlled.

6.

After suffering serious injuries in a car accident, Julio is advised by his doctor to stay in bed for a few months and to refrain from engaging in any form of physical activity. A few months later, after recovering completely from his injuries, Julio notices that his body has changed. His arms and legs are much thinner than before and his muscles are soft and flaccid. What could be a possible explanation for this?

Due to the lack of use, Julio’s muscles have lost their tone.

The extended period of bed rest has triggered hypertrophy in Julio’s muscles.

The extensive period of bed rest has led to an increase in the diameter of Julio’s muscles.

The car accident may have permanently damaged Julio’s skeletal muscles.

7.

How many cervical vertebrae are present in the human body?

Five

Seven

Nine

Eleven

8.

Identify an accurate statement about the bony thorax.

The thoracic cage has eight pairs of true ribs.

The xiphoid is the inferior portion of the sternum.

Rib pairs seven to twelve of the thoracic cage are the true ribs or vertebrosternal ribs.

Rib pairs five to eight of the thoracic cage are the false ribs or vertebrocostal ribs.

9.

Law enforcement officials in New Hampshire find human skeletal remains in a construction site. They suspect that the remains may have belonged to the victim of a homicide. They take the bones to the forensic department for a medical investigation. Ben, a forensic expert, is asked to conduct a preliminary examination of the bones. Ben first has to determine whether the victim was male or female. Which of the following would help him arrive at a conclusion?

A male skeleton would have a greater number of bones.

A female skeleton would have denser and thicker bones.

A male skeleton would have a broader pelvic girdle.

A female skeleton would have a greater pubic angle.

10.

Which of the following is a fibrous tissue that connects skeletal muscle to bone?

Ligament

Cartilage

Tendon

Fascia

11.

Identify an accurate statement about synovial joints.

Saddle joints can perform all types of movements, including rotation.

Hinge joints are found in the knuckles of the fingers.

Hips and shoulders have ball-and-socket joints.

Gliding joints can only rotate.

12.

Which of the following is a similarity between ligaments and tendons?

Both ligaments and tendons cannot withstand stress.

Both ligaments and tendons help connect bone to bone.

Both ligaments and tendons help connect bone to muscle.

Both ligaments and tendons are types of connective tissue.

13.

What is the name of the condition that is characterized by a reduction in bone density after 50 years of age or especially during menopause in women?

Osteoporosis

Osteoarthritis

Gout

Rheumatoid arthritis

14.

Identify an accurate statement about bone fractures.

A comminuted fracture is a fine fracture that does not completely break the bone.

Greenstick fractures occur more often in adults than in children.

In a compound fracture, the bone is pushed out through the skin.

A hairline fracture occurs when the bone is crushed to such an extent that it becomes fragmented.

15.

For the past few months, Maria has been experiencing pain in the joints of her hands and feet. Her joints have become unusually stiff and swollen, and the pain now appears to be spreading to her elbows and knees as well. She finally decides to visit a health care facility for a thorough medical examination. The doctor conducts a detailed examination and asks Maria to take some tests. On analyzing the test results, the doctor tells her that she is suffering from an autoimmune disease that is affecting the connective tissue in her joints. From which condition is Maria most likely suffering?

Septic arthritis

Rheumatoid arthritis

Osteoporosis

Gout

Identify an accurate statement about fibromyalgia syndrome (FMS).

Fibromyalgia syndrome is an acute pain syndrome that can last up to a week.

The majority of fibromyalgia patients are men.

Fibromyalgia syndrome is typically characterized by muscular inflammation.

There is no set treatment for fibromyalgia syndrome.

18.

Nine-year-old Johnathan has been experiencing muscle weakness since birth, which has been increasing progressively. The doctors have examined and diagnosed him with an incurable genetic disease that typically affects the muscles. The doctors are now advising him to use a wheel chair to move around.

Identify an accurate statement about x-rays.

Bones have the highest density and absorb x-rays the most.

Water allows x-rays to pass through it more easily than air.

Low-density areas typically show up on an x-ray film as dark regions.

An x-ray provides a two-dimensional view of a specific area.

Cindy has been admitted to the oncology department of a healthcare facility. The doctor suspects that she might have a tumor growing in her left lung, behind her heart. He directs her to the diagnostic department and instructs a technician, Larry, to take an x-ray of her chest. Larry asks Cindy to stand very close to an x-ray film, with her back facing the x-ray machine. The x-ray machine is positioned approximately six feet away from where Cindy is standing.
