Read the following passage and answer if the question is true or false.
Passage: The internal intercostal muscles have fibres that are angled obliquely downward and backward from rib to rib. These muscles can therefore assist in lowering the rib cage, adding force to exhalation.

Question: do the internal intercostal muscles contract during inspiration?

Is the answer True or False? Respond with only "True" or "False" and no additional text.
False. The internal intercostal muscles primarily assist in lowering the rib cage during exhalation. They do not contract during inspiration.
