The breathing pump muscles are a complex arrangement that form a semirigid bellows around the lungs. Essentially, all muscles that attach to the rib cage have the potential to generate a breathing action, but the principal muscles are shown in figure 1.7.

quiet inspiration: 1 muscle used. - thorax expands in the vertical dimension (superior/inferior) - primary muscle of inspiration = DIAPHRAGM. forced inspiration: many muscles used (because you need more air) - thorax expands in vertical dimension, lateral dimension, and anterior/posterior dimensions.

elevation of ribs and increase in size of thoracic cavity due to descent of diaphragm and expansion of thoracic wall;pressure within thorax decreases (below atmospheric pressure), air rushes into the lungs(3 phases: quiet , deep and forced) Describe the expiration process.

Inspiratory Muscles. The principal muscle of inspiration is the diaphragm, a domed sheet of muscle that separates the thoracic and abdominal cavities. The diaphragm attaches to the lower ribs, as well as to the lumbar vertebrae of the spine.

MUSCLES OF RESPIRATION. Respiration involves Inspiration and Expiration which are accompanied by the alternate increase and decrease of the volume of thoracic cavity. Inspiration is an active process and is achieved by increase in all diameters of thoracic cavity.

The muscles involved in inspiration are: Diaphragm: Diaphragm is the primary muscle of inspiration.It increases all the three diameters of thorax. When the diaphragm contracts in inspiration, initially the lower ribs are fixed and the dome of the diaphragm descends, thus increasing the vertical diameter of thorax.

- origin: mastoid process of temporal bone. - course down and forward. - insertion: sternum and clavicle. - functions: elevates sternum (and therefore rib cage) when both left and right muscles are contracted, and rotates head when only one side contracts.

Lung function 1. \ Normal respiratory movements |. Normal respiratory movements - Respiratory movements introduce oxygen into the alveoli and expel carbon dioxide. The lungs are situated inside the pleural cavity of the thorax and are wrapped in the pleural membrane. The lungs are unable to extend by themselves.

which muscles are used during normal inspiration
Diaphragm muscles are used during normal inspiration. The diaphragm muscles are used during normal inspiration.
