Identify the correct statement based on diagram shown:

Options

  1. AThe number of cervical vertebrae is seven in all the mammals including human beings
  2. BThe vertebral column serves as the point of attachment for the ribs only.
  3. CSternum is a flat bone on the ventral midline of thorax.
  4. DOur vertebral column is formed by 26 parallelly arranged units called vertebrae

Correct answer

C. Sternum is a flat bone on the ventral midline of thorax.

Step-by-step solution

Our vertebral column is formed by 26 serially arranged units called vertebrae and is dorsally placed. It extends from the base of the skull and constitutes the main framework of the trunk. Each vertebra has a central hollow portion (neural canal) through which the spinal cord passes. First vertebra is the atlas and it articulates with the occipital condyles. The vertebral column is differentiated into cervical (7), thoracic (12), lumbar (5), sacral (1-fused) and coccygeal (1-fused) regions starting from the skull.
