Rhomboid Major

This section is about the
muscles of the human torso

The rhomboid major muscles are deep muscles located in the upper-back (posterior torso) of the human body.

The rhomboid major muscles are immediately below (inferior to) the rhomboid minor muscles. Both of these are pairs of muscles located on each side of the upper-spine, between the shoulder blades.

Origin, Insertion and Actions of the Rhomboid Major muscles:

Point(s) of Origin:	Spinous processes of vertebrae T1 to T4.
Point(s) of Insertion:	Medial border of the scapula (shoulder bone)
Action(s):	Braces and rotates the scapula (shoulder bone) Pulls the scapula (shoulder bone) towards the spine.

The rhomboid major is labelled on our diagram of human posterior muscles.
