What is the origin and insertion of M latissimus dorsi?
Origin and insertion
The latissimus dorsi muscle spans over the lumbar and lower thoracic regions of the back. ... Vertebral part: originating from the spinous processes of the 7th to 12th thoracic vertebrae and the thoracolumbar fascia. Costal part: having origins from the 9th to 12th ribs.
Is the latissimus dorsi attached to the scapula?
Latissimus dorsi attaches to the inferior angle of the scapula. ... Type 1, Direct Attachment: muscular slips are anchored directly onto the inferior angle of the scapula. Type 2a, Indirect Attachment: few muscle fibres with a soft, fibrous link between the two (fascia).
