What is the most precise description of a false rib?
A) A rib that does not articulate with the vertebral column
B) A rib that never ossifies, but remains as cartilage throughout life
C) A rib that connects directly to the sternum by its own costal cartilage
D) A rib that connects indirectly to the sternum by a costal cartilage, or has no connection to the sternum
E) A rib that has no cartilaginous connection to the sternum
False Rib
Refers to the ribs that do not directly attach to the sternum but are connected to the true ribs above them.
Costal Cartilage
Flexible connective tissue that links the ribs to the sternum, facilitating the expansion and contraction of the chest cavity.
Sternum
The long, flat bone located in the center of the chest, to which the ribs are attached anteriorly, also known as the breastbone.

Final Answer :
D
Explanation :
A false rib is a rib that either indirectly connects to the sternum by a costal cartilage (ribs 8-10) or has no connection to the sternum at all (ribs 11-12). False ribs do articulate with the vertebral column and can ossify during development, so options A and B are incorrect. Option C describes a true rib, which directly connects to the sternum. Option E is also incorrect, as costal cartilage is still involved in the attachment of false ribs to the body.
