What is the physical relationship of the intercostal to each other?
Inhalation, exhalation
What muscle controls breathing?
The diaphragm, the external intercostal and the interchondral portion of the internal intercostal muscles are the main muscles that control breathing. Other muscles are sometimes used, but only if the person has a breathing disorder or if the body needs energy very quickly.
How are diaphragm and intercostal muscles stimulated?
The diaphragm is stimulated the same way all other muscles are - nerve impulses that originate in the brain (or sometimes the spinal cord). The intercostal muscles expand during inhalation and contract during exhalation in response to the movement of the lungs by the diaphragm.
Why is breathing affected by muscular dystrophy?
First of all, it matters what type of MD you have, but generally since the disease weakens your muscles to the diaphragm, intercostal muscles and other muscles involved in breathing begin to die, and make breathing harder and harder.
Which muscles are involved in inhalation and exhalation?
The diaphragm & the external intercostal muscles (the muscles between the ribs that course downward) are the two most important muscles of inhalation, but there are many other muscles that also contribute to this process. Other muscles of inhalation include: -Pectoralis major -Pectoralis minor -Serratus anterior -Costal levators -Subclavius -Serratus posterior superior -Serratus posterior inferior
What process do mammals use to breathe?
In mammals the muscles that participate in the breathing process are the diaphragm and the intercostal muscles. In respiratory insufficiency other muscles can help the respiration, the muscles of the shoulders, neck, thorax and abdomen. The diaphragm (exclusive of mammals) and the intercostal muscles can contract or relax varying the volume of the thorax (the compartment where the lungs are located). The changing of the thorax volume forces inhalation or expiration. When the thorax volume is increased an internal pressure lower than the atmospheric pressure (external) is created and gases naturally enter the lungs. When the thorax volume is lowered the internal pressure rises above the external pressure and the air is expelled from the lungs.
What is the important muscle of inspiaration?
Most important muscle of inspiration is the diaphragm, which upon contraction, pulls the base of the lung down and increases the pressure inside of the lung, drawing air into the lungs. Other muscles that are not as important except for in forced inspiration are the intercostal muscles and sternocleidomastoid muscles, which only work when forced expiration is required as well :)

How are boys' relationships with each other described in cat's eyes and how do they differ from the relationships between girls?
boys relationship with each other is more than physical where as girls relationship is purely physical and emotional.
What is the large of muscle that controls the size of the chest cavity?
The large muscle below the lungs that make them expand and bring in air is called the diaphragm. (dye-uh-fram). During inhalation, the diaphragm contracts, thus enlarging the thoracic cavity (the external intercostal muscles also participate in this enlargement). This reduces intra-thoracic pressure: In other words, enlarging the cavity creates suction that draws air into the lungs. When the diaphragm relaxes, air is exhaled by elastic recoil of the lung and the tissues lining the thoracic cavity in conjunction with the abdominal muscles, which act as an antagonist paired with the diaphragm's contraction.During exercise or stress or any other cause of labored breathing, air movement is assisted by scalenes, sternocleidomastoid, intercostal muscles, serratus posterior (inferior and superior), all the abdominal muscles, and maybe levator costorum (we still dont know their exact function).the diaphragm, the internal and external intercostal muscles and other accessory muscles such as sternocleidomastoid and others.

What makes the relationship symbiotic?
A relationship is symbotic when both of those involved give and receive physical, emotionally, or other types of benefits.
