Choose the incorrect statement from the following.a. 12 pairs of ribs...
Incorrect statement: Ribs dorsally articulate with sternum and ventrally with the vertebral column.
Explanation:
The correct statement is that ribs ventrally articulate with the sternum and dorsally with the vertebral column. This means that the ribs are attached to the sternum in the front of the body and to the vertebral column (specifically the thoracic vertebrae) at the back of the body.
Details:
Ribs:
- The ribs are long, curved bones that form the rib cage, which protects the thoracic organs such as the heart and lungs.
- There are 12 pairs of ribs in the human body.
Articulation with sternum and vertebral column:
- Ribs ventrally articulate with the sternum: The anterior ends of the ribs are connected to the sternum through cartilaginous attachments called costal cartilages. The first seven pairs of ribs connect directly to the sternum, while the next three pairs are indirectly connected through cartilage connections.
- Ribs dorsally articulate with the vertebral column: The posterior ends of the ribs are connected to the thoracic vertebrae through joints called costovertebral joints. These joints allow for movement and flexibility of the rib cage during breathing.
Bicephalic nature of ribs:
- The term "bicephalic" means having two heads or attachments.
- Ribs are not bicephalic. Each rib has a single head that articulates with the vertebral column and a single tubercle that articulates with the transverse process of the corresponding thoracic vertebra.
Attachment with sternum:
- Ribs are attached to the sternum with the help of hyaline cartilage.
- The costal cartilages connect the anterior ends of the ribs to the sternum.
- This cartilage allows for some flexibility and movement of the rib cage during breathing.
Therefore, the incorrect statement is option B, which states that ribs dorsally articulate with the sternum and ventrally with the vertebral column. The correct statement is that ribs ventrally articulate with the sternum and dorsally with the vertebral column.

Choose the incorrect statement from the following.a. 12 pairs of ribs...
Statements 'b' and 'c' are incorrect. There are 12 pairs of ribs. Each rib is a thin flat bone connected dorsally to the vertebral column and ventrally to the sternum. It has two articulation surfaces on its dorsal end and is hence called bicephalic. The articulation occurs with the help of hyaline cartilage.
