Question

the intercostal muscles between the ribs and diaphragm control​

Answer 1

Answer:

Embryologically, they are formed as the diaphragm etches down the inner surface of the thorax and the primitive rib cartilage condenses. The external intercostal muscles are involved in inhalation. The internal intercostal muscles are involved in exhalation.

Answer 2

Explanation:

Intercostal muscles lie in the spaces between the ribs.

There are three layers of intercostal muscles:

The external intercostals , the internal intercostals, and the innermost intercostals.

When you exhale: the external intercostal muscles relax and the internal intercostal muscles contract. The functions of the innermost intercostals are similar to those of internal intercostals.
