The various muscles of respiration aid in both inspiration and expiration, which require changes in the pressure within the thoracic cavity. The respiratory muscles work to achieve this by changing the dimensions of the thoracic cavity.
The principal muscles are the diaphragm, the external intercostal and the interchondral part of the internal intercostal muscles. Both the external intercostal muscles and the intercondral elevate the ribs, thus increasing the width of the thoracic cavity, while the diaphragm contracts to increase the vertical dimensions of the thoracic cavity, and also aids in the elevation of the lower ribs.
Accessory muscles are typically only used when the body needs to process energy quickly (e.g. during heavy exercise, during the stress response, or during an Asthma attack). The accessory muscles of inspiration can also become engaged in everyday breathing when a breathing pattern disorder exists.

What is active phase of respiration?
inspirationInpiration involves contraction of muscles. This is an energy requiring process
What type of cellular respiration causes muscle contraction?
Aerobic cellular respiration produces energy for muscle contraction but this is not what causes the contractions. The binding properties between the proteins actin and myosin are what give muscles the ability to contract.
What is myospasm?
A myospasm is a muscle spasm - a sudden jerking or twitching caused by contraction of the muscles.
What requires acetylcholine for contraction?
Anerobic contraction of muscles.
What do you mean by orgasms?
An "orgasm" in a male is the release of sperm from the tip of the penis. It is caused by spasmodic contraction of muscles at the base of the penis.
How is breathing different from tissue respiration?
Breathing is the physical contraction of muscles such as the internal and external intercostals that draw air into and out of the lungs. Tissue respiration involves the tissues using Oxygen brought to them in the blood and respiring to produce CO2.
Is Vasodilation is a widening of the lumen due to smooth muscle contraction?
No.Vasodilatation, ie, widening of vascular lumen is caused due to vascular smooth muscles' relaxation.While, vasoconstriction, ie, decrease in diameter of the lumen is caused due to smooth muscle contraction.
When muscle cells undergo anaerobic respiration they become fatigued and painful this is now know to be caused by?
This is caused by a buildup of lactic acid.
An imbalance caused by contraction of pectoralis minor would result in what type of body position. what opposing muscles might be affected by this contraction?
It commonly causes scapula problems and results in rounded shoulders.
Why is respiration important to muscle contraction?
well, your muscles produce a lot of ATP (which is produced in the mitochondria, which is a part of a cell, and this is the case for nearly, but with some exceptions or living cells) this is important because during respiration ATP is also produced.
What the opposite of Contraction?
The general opposite of contraction is expansion, or possibly inflation. For muscles, the opposite of contraction is relaxation.
What is Thompson's disease?
A hereditary disease of the muscles characterized by prolonged contraction of the muscles whenever voluntary motion is attempted, contraction and relaxation being slow and the muscles stiff.
