These are the muscles that move the rib cage and they work together:
- Diaphragm (Prime mover of inhalation). If you need to breathe deeper you will use these:
- Scalenes (Elevate rib cage, assist in inhalation)
- Sternocleidomastoid (Elevate Rib Cage, assist in inhalation)
- Pectoralis minor (Elevate Rib Cage, assist in inhalation)
- External Intercostals (Elevate rib cage, assist in inhalation)
- Internal Intercostals (Depress, assist in exhalation)
The diaphragm is under both voluntary control (holding your breath) and involuntary control (sleeping, reading)
What else can I help you with?
Does exhalation occur when the diaphragm and rib cage muscles relax?
Yes, exhalation occurs when the diaphragm and muscles of the rib cage relax.
What protects the lungs and supports breathing?
The Rib Cage, Sternum and the Diaphragm.
What happens to your diaphragm rib cage and lungs often you exhale?
Your diaphragm expands, your rib cage goes up, and your lungs also expand. I learned this in science.
Is your diaphragm below your rib cage?
yes
What is the breathing line under the lung?
It is called the Diaphragm, which is under the lungs and rib cage. ---- The Diaphragm is what moves the rib cage up and down when you breath in and out.
Does the axial skeleton assist in respiration?
No really. The muscles that move the rib cage are involved in breathing along with the diaphragm.
What are you doing when the diaphragm lowers and the rib cage expands?
Inhaling.
Does the rib cage move up and down when we exhale?
When we exhale, the rib cage moves down and inward as the diaphragm relaxes and moves upward. This action decreases the volume of the thoracic cavity, leading to an increase in pressure that pushes air out of the lungs. So, during exhalation, the rib cage does not move up; rather, it moves down.
Protects the lungs and supports breathing?
The Rib Cage, Sternum and the Diaphragm.
When you breath where does your rib cage move?
in out in out
When the rib muscles and diaphragm relax and the chest cavity becomes what?
When the diaphragm and muscles of the rib cage relax, the thoracic cavity becomes smaller. These changes occur during exhalation.
What happens to the movement of the chest when inhaling and exhaling?
Both... your chest expands - pushing your rib-cage out, and your diaphragm pushes downwards - forcing your organs to move outwards slightly.
