Herniated disk are most likely to occur in _____________ region.
- A.
Cervical
- B.
Lumbar
- C.
Sacral
- D.
Thoracic
Correct Answer
B. LumbarExplanation
Herniated disks are most likely to occur in the lumbar region. The lumbar region refers to the lower back area of the spine, which is the most common site for herniated disks. This is because the lumbar region bears most of the body's weight and is subjected to a lot of stress and strain. Herniated disks occur when the soft inner portion of a disk protrudes through the tough outer layer, causing pain and discomfort. Therefore, the lumbar region is the most susceptible to this condition.Rate this question:

_______________means to move towards the midline.
- A.
Adduction
- B.
Abduction
- C.
Extension
- D.
Flexion
Correct Answer
A. AdductionExplanation
Adduction refers to the movement of a body part towards the midline of the body. This means that when a body part is adducted, it is moved closer to the center of the body. For example, when you bring your arms down to your sides from a raised position, you are performing adduction. This movement is opposite to abduction, which is the movement of a body part away from the midline. Extension refers to the straightening or lengthening of a body part, while flexion refers to the bending or decreasing of the angle of a body part.Rate this question:

Yellow marrow
- C.
Osteon units
- D.
RBCs
Correct Answer
C. Osteon unitsExplanation
Compact bone contains structures called osteon units. These units consist of concentric rings of bone tissue called lamellae, which surround a central canal called the Haversian canal. The Haversian canal contains blood vessels, nerves, and connective tissue. The lamellae also contain lacunae, which house bone cells called osteocytes. Canaliculi, tiny channels, connect the lacunae and allow for communication between osteocytes. Osteon units are responsible for providing strength and support to compact bone, as well as facilitating the exchange of nutrients and waste materials within the bone tissue.Rate this question:

As we age the growth plates disappear throught the process of ____________
- A.
Necrosis
- B.
Ossification
- C.
Ischemia
- D.
None of these
Correct Answer
B. OssificationExplanation
Ossification is the process by which the growth plates in our bones disappear as we age. During ossification, new bone tissue is formed and replaces the cartilage in the growth plates, leading to their closure. This process is essential for the normal development and growth of bones, and it helps to increase bone density and strength. Necrosis refers to the death of cells or tissues, and ischemia refers to the inadequate blood supply to a particular organ or tissue. Therefore, neither necrosis nor ischemia is involved in the disappearance of growth plates.Rate this question:

High ketones can be seen in times of starvation or anorexia nervosa
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
High ketones can be seen in times of starvation or anorexia nervosa because in these conditions, the body does not have enough glucose to use as fuel. As a result, it starts breaking down stored fat for energy, which leads to the production of ketones. Ketones are a byproduct of fat metabolism and their levels increase in the blood and urine when the body is in a state of ketosis. This is a natural response to provide an alternate source of energy when glucose is scarce.Rate this question:
