The vertebral column does not include a
- rib.
- vertebra.
- sacrum.
- coccyx.
Introduction: The spinal cord can be defined as the cylindrical bundle of the nerve fibers and connected tissue. It is surrounded in the spinal region and joins approximately all the body parts to the brain. It forms the central nervous system with the brain. The vertebral column encloses the spinal cord that travels inside the spinal canal. It is formed from the central opening in each vertebra.
Answer to Problem 1PL
Correct answer:
The correct answer is the option (a) Rib.
Explanation of Solution
Explanation/justification for the correct answer:
Option (a) Rib. A rib refers to a curved bone located in a person's chest. The ribs provide protection to the internal organs. Ribs are flexible and strong cage that is located around the soft inside parts. Hence, the option (c) is correct.
Explanation for the incorrect answer:
Option (b) Vertebra. A vertebra is one of the 33 bony segments which form the spinal cord of the humans. There are 7 cervical vertebra, 12 thoracic vertebra, 5 lumbar vertebra, 5 sacral vertebra and 4 coccygeal vertebra. Hence, the option (b) is incorrect.
Option (c) Sacrum. It is a triangular bone located in the lower part of the back. It is formed from the fused vertebrae. It is located between the two hip bones of the pelvis region. Hence, the option (c) is incorrect.
Option (d) Coccyx. It is a small triangular bone located at the base of the spinal cord in humans and some apes. It is formed by the fusion of the vestigial vertebrae. Hence, the option (d) is incorrect.
A rib refers to a curved bone located in a person's chest. The ribs provide protection to the internal organs in thorax region. Hence, the option (a) is correct.
