Carpal tunnel |
Passageway deep to flexor retinaculum Latterally: Between scaphoid and trapezium Medially: pisiform and hamate |
|
|
Median nerve |
Supplies 2.5 thenar muscles Supplies 1& 2 lumbricals |
|
|
Ulnar nerve |
Supplies hypothenar muscle Medial 2 lumbricals AD Deep head of FPB |
|
|
Hypothenar muscles |
On opposite side as thumb Produce hypothenar eminence on palm |
|
|
Nerve of fine movements |
Ulnar nerve Innervates muscles that are concerned with intricate hand movements |
|
|
Sternoclavicular joint |
Synovial saddle joint (Functions like ball in socket) Divided into 2 comaprtments by articular disc |
|
|
SC movement/strength |
Very strong Allows movement of pectoral girdle and upper limb Clavicle can be ride 60° upward And 30° anteriorly/posterioely |
|
|
Acromioclavicular joint |
Plane synovial Covered by fibrocartilage Separated by an incomplete wedge shaped articular disc |
|
|
Scapulothoracic |
Conceptual joint (not a "true" joint) - no joint capsule, etc |
|
|
Scapulo humeral rhythm |
Scapula and humerus move in a 1:2 ratio. If arm is abducted by 180° -60° occurs by scapula rotate -120° occurs by humerus rotates |
|
|
Glenohumeral joint |
Synovial Ball and socket Wide movement Relatively unstable |
|
|
Glenoid labrum |
Ring like fibrocartilaginous lip surrounding glenoid cavity Deepens cavity |
|
|
Glenoid cavity holding power |
Hold only 1/3 of humeral head Head held in place by rotator cuff muscles |
|
|
Glenohumeral joint movements |
More freedom to move than any other joint Due to lossness of joint and the configuration of spherical head in shallow cavity |
|
|
