EXAM 2: Upper Limbs Flashcards
Pectorial girdle
Axial Skeleton connects to appendicular skeleton
clavicle and scapula
Ligaments of the Shoulder
Coracohueral ligament (Coracoid Process to head of humerus)
Glenohumeral Ligament (gleniod cavity to humeral head)
Shoulder joint
Glenohumeral Joint
Dislocated shoulder
ligaments are ripped or stretched
disarticulation
Parts of the scapula
- Glenoid Cavity
- Spine of Scapula
- Acromion
- Coracoid Process
What is the section of the upper limb called the arm?
Shoulder to elbow
Capitulum
Anterior side of humerus
ball section
Trochlea
Anterior side of humerus
square section
Plexus
Criss corssing of nerve fibers
Where does the brachial plexus begin
Ventral Rami- supplies all the feeling/movement to the upper limb
what are the bony connections of the elbow
- head of radius to capitulum of humerus
- olecranon/coramoid process of ulna to the trachela of humerus
Elbow Ligaments
Anular Ligament
Ulnar Colateral Ligament
Radial Colateral Ligament
Anular Ligament
wrapped around the head of radius. keeps radius locked in during pronation and supination
Ulnar Colateral Ligament
connects ulna to the humerus (more medial)
Radial Colateral Ligament
connects radius to the humerus (more lateral)
What keeps the elbow from being able to hyperextend?
Humerus and ulna
Which is stronger supination or pronation?
Supination because bones are parallel
Is the head of the ulna distal or proximal?
Distal
Is the head of the radius distal or promixal?
Proximal
What is anastomoses?
Interconnection of blood vessels
How to know if left or right hand?
If you can see pisiform then you are anterior, then look for the thumb
Bones of the hand?
Carpals (8)
Metacarpals (5; I-IV)
Phalanges (14)
Proximal Row
Lateral to Medial
Scaphoid, Lunate, Triquetrium, Pisiform
Distal Row
Lateral to medial
Trapezium, Trapezoid, Capitate, Hamate
What are the joint of the wrist
Radius to scaphoid and lunate
What are the wrist joint movements?
Flexion
Extend
Hyperextend
Adduct
Abduct
Supination
Pronation
Cutaneous Nerve
Nerve coming from the skin
