Abduction of the arm at the glenohumeral cavity is mainly controlled by
Flexion of the forearm at the elbow joint is controlled primarily by
Extension of the arm at the elbow joint is controlled mainly by
Flexion of the fingers is controlled mainly by
abduction and adduction of the index, ring and middle fingers is controlled dominantly by
A tap on the tendon of biceps in the cubital fossa tests for
A tap on the tendon of the triceps posterior to the elbow tests mainly for
All muscles of the anterior compartment of arm are innervated by
musculocutaneous nerve
Most of the muscles of the anterior compartment of the forearm are innervated by
Median nerve
Median nerve innervates all muscles of the forearm except
1- Flexor carpi ulnaris.2- Medial half of the Flexor digitoum profundus.Innervated by the ulnar nerve.
Most intrinsic muscles of the hand are innervated by
the ulanr nerveexcept for thenar muscles & 2 lateral lumbrical muscles. (Median nerve)
All muscles of the posterior compartment of arm and forearm are innervated by
radial nerve
Musculocutaneous nerve
all muscles of the anterior compartment of arm
Median nerve
1- most flexors of the forearm.2- thenar muscles in hand.
Radial nerve
All muscles in posterior compartments of arm & forearm
Ulnar Nerve
1- Most intrinsic muscles of hand.2- Flexor carpi ulnaris + medial 1/2 flexor digitorum profundus.
posterior cutaneous nerve of arm
radial nerve
lateral cutaneous nerve of forearm
a nerve which innervates the palmar surface of the lateral three and half digits
median nerve
dorsolateral aspect of the hand is innervated by
the radial nerve
The nerve which supplies the deltoid
Axillary nerve
A nerve which is related to the posterior aspect of the surgical neck of the humerus
Axillary nerve
A nerve which passes diagonally around the posterior surface of the middle of the humerus in the radial groove
Radial nerve
A nerve which passes posteriorly to the medial epicondyle of the humerus
Ulnar nerve
Tubercle on the inferior surface of the lateral third of the clavicle
Conoid tubercle
The coracoclavicular ligament is attached to
the trapezoid line
The 3 angles of the scapular are
1- Superior2- Inferior3- Lateral
The three borders of the scapula
1- Superior.2- Medial.3- Lateral.
The 2 surfaces of the scapula
1- Costal2- Posterior
The three processes of the scapula
1- Coracoid Process.2- Acromion.3- Spine.
Muscle attached to the infraglenoid tubercle
Triceps Brachii
A muscle attached to the supraglenoid tubercle
Biceps Brachii
The oval small facet on the medial aspect of the acromion articulated with
the clavicle
the region between the lateral angle of the scapula and the attachment of the spine to the posterior surface of the scapula is called
spinoglenoid notch; greater scapular notch
Another name for the bicipital groove
intertubercular sulcus
On the humerus which tubercle is medial and which is lateral
1- Medial: Lesser tubercle.2- Lateral: Greater tubercle.
List the muscles attached to the intertubercular sulcus
1- Medial Lip: Teres Major.2- Floor: Latissimus Dorsi.3- Lateral lip: Pectoralis Major.
The deltoid muscle is attached to which part of the humerus?
Deltoid tuberosity
The superior facet on the greater tubercle is an attachment site for
The middle facet on the greater tubercle is an attachment site for
The inferior facet on the greater tubercle is an attachment site for
Teres Minor
The muscle attached to the lesser tubercle is
The tendon of the long head of biceps brachii passes through
The intertubercular sulcus
The sternoclavicular joint occurs between
the clavicular notch of the manubrioum of the sternum and the proximal end of the clavicle
Describe the sternoclavicular joint
It is synovial and saddle-shaped.
What are the four ligaments which support the sternoclavicular joint
1- anterior sternoclavicular ligament.2- posterior sternoclavicular ligament.3- Interclavicular ligament.4- Costoclavicular ligament.
The acromioclavicular joint s supported by 2 ligaments which are:
1- acromioclavicular ligament.2- coracoclavicular ligament.
Coracoclavicular ligament is composed of
1- Trapezoid ligament.(trapezoid line)2- Conoid ligament. (conoid tubercle)
The articular surfaces of the glenohumeral joint are covered by
Hyaline Cartilages
The glenoid cavity is deepened and expanded peripherally by the
glenoid labrum
The synovial membrane invests the tendon of the long head of biceps when it is
in the joint and intertubercular sulcus
The dislocation of the humerus is most often an
anteroinferior dislocation
The disorders of the rotator cuff are
1- Impingement.2- Tendinopathy.
Subdeltoid subacromial bursa is located
between the supraspinatus and deltoid muscle laterally, and the acromion medially.
The superficial muscles of the shoulder are
1- The trapezius.2- The deltoid.
What's the function of the trapezius?
It attaches the scapula and the clavicle to the trunk
What's the function of the deltoid?
It attaches the scapula and the clavicle to the humerus
The scapula is attached to the vertebral column by
1- Levator Scapulae.2- Rhomboid Major.3- Rhomboid Minor.
