Question

Select the correct statement with respect to locomotion in humans

• A. A decreased level of progesterone causes osteoporosis in old people.
• B. Accumulation of uric acid crystals in joints causes their inflammation.
• C. The vertebral column has 10 thoracic vertebrae.
• D. The joint between adjacent vertebrae is a fibrous joint.

Answer 1

The Correct Option is B

To determine the correct statement regarding locomotion in humans, let us evaluate each option:

1. Option 1: "A decreased level of progesterone causes osteoporosis in old people."

   This statement is incorrect. Osteoporosis is a condition characterized by weak and brittle bones, but it is more commonly associated with decreased levels of estrogen rather than progesterone. Estrogen plays a crucial role in maintaining bone density.

2. Option 2: "Accumulation of uric acid crystals in joints causes their inflammation."

   This statement is correct. The accumulation of uric acid crystals in joints can lead to a condition known as gout, which results in inflammation, pain, and swelling in the affected joint.

3. Option 3: "The vertebral column has 10 thoracic vertebrae."

   This statement is incorrect. The human vertebral column comprises 12 thoracic vertebrae, not 10.

4. Option 4: "The joint between adjacent vertebrae is a fibrous joint."

   This statement is incorrect. The joints between adjacent vertebrae are called intervertebral discs, which are examples of cartilaginous joints (specifically symphysis), not fibrous joints.

Therefore, the correct answer is: "Accumulation of uric acid crystals in joints causes their inflammation."
