diaphragm
The diaphragm.
Smooth muscle.
ATP is required during a muscle contraction because it provides the energy needed for the muscle fibers to contract and generate force. Without ATP, the muscle would not be able to contract effectively.
The intercostal muscles, (muscles between the ribs), contract.
diaphram
the diaphragm is the muscle(s) that are most important muscle used in inspiration (inhalation)?
The interval between expiration (breathing out) and inspiration (breathing in) is called the respiratory cycle. During this cycle, the lungs expand and contract to allow air to move in and out of the body.
The dome-shaped muscle under the thoracic cavity is the diaphragm. Its function is to contract to increase the volume of the thoracic cavity, thereby decreasing pressure in the lungs and causing inspiration.
Diaphragm
Yes. One possibility is that the load on the muscle exceeds the tension produced by the muscle so that the muscle actually lengthens during contraction (eccentric contraction).
A living muscle needs oxygen in the blood and muscle elasticity to contract and move.
The diaphragm is the prime mover of inspiration, as it contracts and flattens during inhalation, creating a vacuum in the chest cavity that allows air to be drawn into the lungs.
