What muscles have attachments to the scapula?
Each scapula has 17 muscles attached to it: 1. Posteriorly, from superficial to deep: trapezius, rhomboid major, rhomboid minor, supraspinatus, infraspinatus, levator scapulae, teres minor, teres major, latissimus dorsi, serratus anterior, and subscapularis. 2.
Where do muscles attach to the scapula?
The superior border of the scapula extends from the superior angle to the coracoid process. The coracoid process is a hook-like structure that comes off anteriorly from the lateral superior aspect of the ventral side of the scapula. Like the acromion, it is an attachment point for muscles and ligaments.
Does latissimus dorsi attach to the scapula?
Latissimus dorsi muscle arise as broad aponeurosis that originates from the spines of lower six thoracic vertebrae and from the posterior layer of thoracolumbar fascia attached to the spines and supraspinous ligaments of all lumbar vertebrae; sacral vertebrae and posterior crest of ilium, lower 3 or 4 ribs, and an …
Does the deltoid attach to the scapula?

Does the latissimus dorsi attach to the scapula?
Which muscle is in the scapular region?
The deep ‘intrinsic’ or true scapular muscles are the deltoid, supraspinatus, infraspinatus, teres minor, teres major, and subscapularis muscle. The deltoid muscle, which has three parts (clavicular, acromial, and spinal), is superior and forms the roundness of the shoulder over the glenohumeral joint.
What muscles have axial skeleton origins and scapula insertions?
Nine muscles cross the shoulder joint to move the humerus. The ones that originate on the axial skeleton are the pectoralis major and the latissimus dorsi. The deltoid, subscapularis, supraspinatus, infraspinatus, teres major, teres minor, and coracobrachialis originate on the scapula.
What muscles are attached to the scapula?
Coracobrachialis arises from the medial part of the tip of coracoids process.
What muscle does not attach to the scapula?
Teres major muscle (Musculus teres major) The teres major is a thick muscle of the shoulder joint.It spans from the inferior aspect of the scapula to the proximal part of the humeral shaft.Unlike the teres minor, the teres major muscle does not attach to the capsule of the glenohumeral joint.Thus it is not regarded as part of the rotator cuff muscles.
How many muscles attach to scapula?
