What's the origin of the latissimus dorsi?
Origin of the latissimus dorsi is from spinous processes of thoracic T7–T12, thoracolumbar fascia, iliac crest and inferior 3 or 4 ribs, inferior angle of scapula and insertion on floor of intertubercular groove of the humerus.
What is the origin of the latissimus dorsi muscle quizlet?
The latissimus dorsi muscle originates on the: posterior crest of the ilium.
Are the origins of the deltoid and latissimus dorsi?
It completely surrounds the shoulder joint from the front, to the back. It arises from the spine of the scapula, from the acromion, and from the lateral third of the clavicle. It's inserted here on the deltoid tuberosity of the humerus.
Where does the latissimus dorsi insertion?
The lateral aspect of the latissimus dorsi muscle builds the posterior border of the axilla. It is felt to contract during resisted adduction of the arm. Its insertion lies anteriorly at the crest of the lesser tuberosity.
What is the origin of the supraspinatus?
Origin. The supraspinatus muscle arises from the supraspinous fossa, a shallow depression in the body of the scapula above its spine. The supraspinatus muscle tendon passes laterally beneath the cover of the acromion.
What is the origin of the pectoralis major muscle quizlet?
Origin: Ribs 3-5 near costal cartilages, Inserts medial border and superior surface of coracoid process of scapula, innervation Medial Pectoral nerve, Fx, Stabilizes scapula by drawing it inferiorly and anteriorly against thoracic wall. ... You just studied 4 terms!
What is latissimus dorsi muscle?
Introduction. The latissimus dorsi muscle is a broad, flat muscle that occupies the majority of the lower posterior thorax. The muscle's primary function is of the upper extremity but is also considered to be a respiratory accessory muscle.
What is the function of the latissimus dorsi quizlet?
- Raises body toward arm during climbing.
What region of the body is the latissimus dorsi?
The latissimus dorsi muscle spans over the lumbar and lower thoracic regions of the back. Depending on the origin, one can distinguish four parts of this muscle: Vertebral part: originating from the spinous processes of the 7th to 12th thoracic vertebrae and the thoracolumbar fascia.
