Clavicle Scapula And Humerus Flashcards
Joints that articulate with the sternum and clavicle
Sternoclavicular joint - medial
Acromion joint - lateral
Name of the fossa on the lateral scapula
Glenoid fossa
Name of a large concave depression over most of the surface of scapula
Subscapular fossa
What is Supregelnoid tubercle and infraglenoid ?
Supra place of attachment for long head of biceps
Infra place of attachment for long head of triceps
How are the humerus and scapula linked
Articulate with the glenoid fossa of the scapula at the glenohumeral joint
how does the head of the humerus articulate with scapula
At the glenoid fossa
Where is the greater tubercle located
On the proximal humerus
Greater tubercle muscle attachments ?
Supraspinatus
Infraspinatus
Teres minor
Where is the surgical neck of humerus
Distal to the tubercles
Why is the surgical neck clinically important
Falls - easily fractures
Axillary nerve runs close to this
What is the deltoid tuberosity
Site of attachment for deltoid muscle
5 key movements of pectoral girdle
DEPRESSION ROTATION RETRACTION EXTENSION PROTRACTION
DR REP
Two large muscles of superficial posterior pectoral girdle
Latissimus Dorsi
Trapezius
Innervation of trapezius
Accessory nerve
Three muscles deep to the trapezius
Rhomboid major
Rhomboid minor l
Levator scapulae
What do the anterior and posterior fibres of deltoid do
Allow for flexion and extension
What is the quadrilateral space bound by
Teres minor above
Teres major below
Long head of triceps medially
Surgical neck of humerus laterally
What nerve travels through the quadrilateral space and what does it innervate
Axillary nerve
Deltoid and teres minor
Names of three head of triceps
Long head
Medial
Lateral
Movements possible at the shoulder joint 5
CIRCUMDUCTION ROTATION ADDUCTION ABDUCTION EXTENSION FLEXION
Scapulo humeral muscles and their role
Supraspimatus
Infraspinatus
Teres minor
Subscapularis
To stabilise the shoulder joint
What three muscles attach to the coracoid process
Pec minor
Corocobrachialis
Short head of biceps brachii
Which muscles attach to the humerus along its shaft
Anteriorly - corobrachialis , deltoid , brachial is and brachioradialis
Posteriorly- medial and lateral heads of triceps
Is the scapula anterior or posterior
Posterior
Key muscle for protraction of the scapula
Serratus anterior
What is the shoulder girdle formed by
Scapula posteriorly
Clavicle anteriorly
Innervation of latissimus Dorsi
Thoracodorsal nerve
Function and innervation of deltoid
Axillary nerve
Major abductor of the arm
Six muscles that attach the scapula to the humerus
Deltoid Infraspinatus Supraspimatus Subscapularis Teres major Teres minor
Rotator cuff muscles
Supra and infraspimatus
Subscapularis
Teres minor
Where does the triceps brachii converge
Onto a single insertion point, olecranon of the ulna
What are all three parts of the triceps brachii innervated by and vasculature
Radial nerve
Profunda brachii artery
