|
|
Which spinal nerves innervate the dermatomes of the upper limbs? |
Ant. & Post. rami of spinal nerves C4-T2 |
|
|
Where the C5 innervates? |
ANTERIOR surface – lateral arm and forearm to the wrist |
|
|

|
|
Structures involved in superficial venous drainage of the upper limb |
- Cephalic vein - Basilic vein - Median cubital vein |
|
|
What is the lymphatic system? |
It's responsible for draining extracellular fluids in the body that are not pickedup by the venous system |
|
|
How does lymph in the upper limb drain? |
Lymph from digits and palm ↓ drain to Lymphatic vessels ↓ drain to Axillary lymph nodes (in the axilla) |
|
|
Characteristic of the Lymphatic vessels |
Lymphatic vessels ↓ travel along side Superficial veins of the lymph |
|
|
Name & Identify the bones that compromise the Pectoral Girdle |
1. Clavicle 2. Scapula |
|
|
What are the forms of the Clavicle & the Scapula |
|
|
|
Name the 2 ends of the Clavicle |
. |
|
|
Which of the 2 bones contains conoid tubercle? |
CLAVICLE -> on its inferolateral surface |
|
|
Where is the Scapula located? |
posterolateral aspect of thorax, over ribs II-VII |
|
|
What do we find on the ant. view of the scapula? |
- Subscapular fossa - Acromion - Coracoid process |
|
|
What do we find on the lat. view of the scapula? |
- Glenoid fossa (cavity) -> Supraglenoid & Infraglenoid tubercles (which are the origins of biceps brachii & triceps brachii) |
|
|
What do we find on the post. view of the scapula? |
- Spine of the scapula - Suprasinous fossa - Infraspinous fossa |
|
|
Describe the skeletal morphology of the Proximal Humerus |
Humerus = "Arm bone"
Features of the Proximal Humerus • Head • Anatomical and surgical necks • Greater and lesser tubercles • Intertubercular and radial grooves • Deltoid tuberosity • Shaft
|
|
|
Name the JOINTS OF THE SHOULDER |
1. Sternoclavicular joint 2. Acromioclavicular joint 3. Glenohumeral joint |

|
Where is the Sternoclavicular joint?
|
|
|
|
Where is the Acromioclavicular joint?
|
|
|
|
Where is the Glenohumeral joint?
|
|
|
|
JOINTS OF THE SHOULDER - common point of the joint classification |
they're all Synovial joint |
|
|
JOINTS OF THE SHOULDER - Difference of the joint classification |
|
|
|
JOINTS OF THE SHOULDER - What movements do Sternoclavicular joint permit? |
|
|
|
JOINTS OF THE SHOULDER - What movements do Acromioclavicular joint permit? |
Gliding like Sternoclavicular joint, but just a bit |
|
|
JOINTS OF THE SHOULDER - What movements do joint Glenohumeral permit? |
-> Permit all mvmts of the shoulder: 1. Flexion/extension 2. Abduction/adduction 3. Circumduction 4. Internal/external rotation
|
|
|
Why is the scapulothoracic joint not a true joint? |
There is no ligamentous attachment between the scapula and near by bones. |
|
|
Scapulohumeral rhythm = involved in which movements? |
1. Humeral movement (at glenohumeral joint)
2. Scapular movement (at scapulothoracic joint)
|
|
|
What exactly is Scapulohumeral rhythm? |
wiki |
|
|
Why is scapulohumeral rhythm so important? |
" Overhead activity of the shoulder, especially repeated activity, is a risk factor for shoulder impingement syndrome" => cause pain |
