What does GHJ stand for?

glenohumeral joint

Deltoid OIIF?

O: spine of scapula, acromion, lateral clavicle I: deltoid tuberosity of humerus Inn: brachial plexus F: shoulder abduction, shoulder flexion, shoulder extension (all occur at GHJ joint)

Latissimus Dorsi OIIF?

O: sacrum, iliac crest, spinous process of lumbar vertebrae, thoracolumbar fascia, lower ribs I: intertubercular groove of humerus Inn: brachial plexus F: extends, adducts and medial rotates humerus at GHJ

Serratus Anterior OIIF?

O: upper 9 ribs I: medial border of scapula Inn: brachial plexus F: protraction of scapula

Supraspinatus OIIF?

O: supraspinous fossa of scapula I: greater tubercle of humerus Inn: brachial plexus F: abduction of humerus at GHJ

Infraspinatus OIIF?

O: infraspinous fossa of scapula I: greater tubercle of humerus Inn: brachial plexus F: lateral rotation of humerus at GHJ

What does fossa mean?

shallow depression in a surface

What fossa(s) does the Anterior part of the Scapula have?

supraspinous fossa and infraspinous fossa

Tres Minor OIIF?

O: lateral border of scapula I: greater tubercle of humerus Inn: brachial plexus F: lateral rotation of arm at GHJ

Subscapularis OIIF?

O: subscapular fossa of scapula I: lesser tubercle of humerus Inn: brachial plexus F: medial rotation of arm at GHJ

subscapular fossa

what muscles make up the Rotator cuff?

supraspinatus, infraspinatus, subscapularis, teres minor

What plays a major role in Glenohumeral Joint stability?

rotator cuff

What is the Rotator Cuff?

compression force of humeral head into glenoid fossa of scapula

Someone rotates their neck to look to the left. Which muscle helps with this movement?

sternocleidomastoid

Someone is trying to move their scapula into elevation, which muscles help with this?

trapezius

Someone is forcefully exhaling, which muscles help with this?

intercostals and obliques (internal/external)

Someone has their arm at their side. They then medially rotate their arm. Which muscles helped with this?

pectoralis major, latissimus dorsi and subscapularis
