Question

how are muscles in lungs different from those in the arms
​

Answer 1

Answer:

The muscles of respiration are also called the 'breathing pump muscles', they form a complex arrangement in the form of semi-rigid bellows around the lungs.

All muscles that are attached to the human rib cage have the inherent potential to cause a breathing action.

Muscles that helpful in expanding the thoracic cavity are called the inspiratory muscles because they help in inhalation, while those that compress the thoracic cavity are called expiratory muscles and they induce exhalation. These muscles possess exactly the same basic structure as all other skeletal muscles, and they work in concert to expand or compress the thoracic cavity.

The speciality of these muscles are that they are composed of fatigue resistant muscle fibers, they are controlled by both voluntary and involuntary mechanisms if we want to take a breath we can, even if we do not think about breathing the body automatically does it.
