4) Phalanges

Answer 1

Vertebrae is the term in its plural form among the options, which refers to the bones that form the vertebral column. The vertebral column supports the body and the rib cage protects vital organs. The correct option is 2.

Step-by-step explanation:

The term in its plural form among the options given is vertebrae, which is the plural of vertebra. The other options have the following plural forms: pleura becomes pleurae, bursa becomes bursae, and phalanx becomes phalanges.

In the context of anatomy:

• The ossicles of the middle ear are part of the axial skeleton.
• The femur is part of the appendicular skeleton.
• The phalanges are part of the appendicular skeleton.
• The bones of the cranium are part of the axial skeleton.
• The ilium is part of the appendicular skeleton.

The vertebral column is a vital part of the human skeleton that supports the upper body and protects the spinal cord. The S-shaped curve of the vertebral column provides strength, support, and flexibility. The rib cage is a set of bones that protect the heart and lungs; its primary function is to shield these vital organs. Hence, 2 is the correct option.
