Which of the Following Muscles Cannot Elevate the Ribs

Question

Which of the following muscles cannot elevate the ribs?
A) External intercostals
B) Serratus anterior
C) Scalenes
D) External oblique
E) Sternocleidomastoid

Accepted Answer

The external oblique muscle primarily functions in the movement of the trunk, such as in trunk rotation and lateral flexion, and in compressing the abdominal contents, rather than elevating the ribs, which is a function associated with breathing.
