- C8
- abduction and adduction of the index, ring and middle fingers is controlled dominantly by
- T1
- A tap on the tendon of biceps in the cubital fossa tests for
- C6
- A tap on the tendon of the triceps posterior to the elbow tests mainly for
- C7
- 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 nerve
except 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
- musculocutaneous
- 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- Superior
2- Inferior
3- Lateral - The three borders of the scapula
-
1- Superior.
2- Medial.
3- Lateral. - The 2 surfaces of the scapula
-
1- Costal
2- 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
- Supraspinatus
- The middle facet on the greater tubercle is an attachment site for
- Infraspinatus
- The inferior facet on the greater tubercle is an attachment site for
- Teres Minor
- The muscle attached to the lesser tubercle is
- subscapularis
- 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.
