The diaphragm is a skeletal muscle that separates the thoracic and abdominopelvic cavities. It is innervated by the phrenic nerve. The diaphragm is the main muscle of respiration, with diaphragmatic contraction responsible for 75% of the air movement in a normal breath at rest. Respiratory control is both voluntary and involuntary. Because of the involuntary control, the diaphragm is commonly mistaken to be made up of smooth muscle, but this is incorrect. The brain's involuntary respiratory centers regulate the activity of the diaphragm and intercostal muscles in response to sensory information (very much like an involuntary reflex arc). These involuntary centers are housed in the brainstem. The cerebral cortex controls voluntary breathing, which also affects the diaphragm and intercostal muscles. For forced inhalation or exhalation, additional skeletal muscles (e.g., pectoralis minor, scalenes, sternocleidomastoid) may also be involved.

What type of muscle is found at the bottum of your chest?
The diaphragm separates the thoracic cavity from the abdominopelvic cavity. It is composed of skeletal muscle.
What type of muscle tissue is diaphragm?
These include the skeletal muscles which are under voluntary control and are made of striated muscle tissue, the visceral muscles which are under involuntary control and are made of smooth muscle tissue, and cardiac muscle tissue which is found only in the heart. Cardiac muscle tissue has properties in common with each of the other two types. Sierra Q
