- Serratus anterior
One of the serratus muscles of the back and thorax. The serrautus anterior originates from the lateral aspect (the side) of first eight to nine ribs and inserts into the medial margin of the scapula (wing bone). The serratus anterior rotates the scapula and pulls it forward and elevates ribs.
- Serratus magnus
One of the serratus muscles of the back and thorax. The serratus magnus originates from the lateral aspect (the side) of the first eight to nine ribs and inserts into the medial margin of the scapula (wing bone). The serratus anterior rotates scapula and pulls it forward and elevates the ribs.
- Serratus posterior inferior
One of the serratus muscles of the back and thorax. The serratus posterior inferior muscle originates, together with latissimus dorsi, from the spinous processes of two lower thoracic vertebrae and the two upper lumbar vertebrae and it inserts into the lower borders of last four ribs. It draws the lower ribs backward and downward.
- Serratus posterior superior
One of the serratus muscles of the back and thorax. The serratus posterior superior originates from the spinous processes of two lower cervical and two upper thoracic vertebrae and it inserts into the lateral side of angles of the second to fifth ribs. It raises the ribs in inspiration.
