Q

Functions of Thoracic Wall

A

Resist the negative internal pressures generated by the elastic recoil of the lungs and inspiratory movements.
Provides attachment for and support the weight of the upper limbs.
Provides attachment for many of the muscles of the upper limbs, neck, abdomen, and back and the muscles of respiration.
