21
Q

How many bones are there in the upper limbs?

22
Q

What dictates the arm?

Study These Flashcards
A

shoulder-elbow

23
Q

True or False?
The head of the humerus larger that the gelnoid cavity which it articulates with?

23
Q

What dictates the forearm?

Study These Flashcards
A

elbow - wrist

24
What is a common site for fracture in the humerus?
surgical neck
25
What are the landmarks on the upper half of the humerus bone?
- head - anatomical neck - surgical neck - greater tubercle (lateral bump) (three large facets of tendon attachment, for rotator cuff muscles) (i) superior facet - supraspinatus muscle (ii) middle facet - infrapinatus muscle (iii) inferior facet - teres minor muscle - lesser tubercle (anterior) (attaches to the subscapularis muscle) - inter-tubercular sulcus/ groove/ bicipital sulcus (lies between the two tubercles) (continues inferioraly on the proximal shaft of the humerus)
26
What are the landmarks on the middle half of the humerus bone?
- radial groove - deltoid tuberosity (bump on the lateral side)
27
What are the 7 landmarks on the lower half of the humerus bone?
1. coronoid fossa (anterior) - interacts with the coronoid on the ulna 2. radial fossa (anterior) - interact with the head of the radius 3. Olecranon fossa (posterior) -interacts with the olecranon on the ulna 4. Trochlea (medial) - articulates with the ulna - pulley shape that extends onto the posterior surface 5. Capitulum (lateral) - articulates with the radius - hemispherical in shape 6. Medial epicondyle 7. Lateral epicondyle
28
What are the articular points on the condyle?
- capitulum - trochlea
29
What is the forearm made of?
radius and ulna
30
Which forms most of the elbow joint with the humerus, the ulna or radius?
ulna
31
What is found on the ulna and where?
- olecranon (posterior) - coronoid process (anterior) - trochlear notch (anterior) - radial notch (anterior) - head (at the distal end) - ulnar styloid process (medial)
32
What is found on the radius and where?
- head (proximal) - neck - radial tuberosity (anterior) - ulnar notch - radial styloid process (lateral side)
33
For the elbow joint: in extension the olecranon (ulna) fits in what?
olecranon fossa (humerus)
34
For the elbow joint: in flexion the coronoid process (ulna) fit in what?
in the coronoid fossa humerus
35
True or False the ulna articulates with the trochlea of humerus and the radius articulates with the capitulum of humerus?
True
36
Elbow joints allow for what kinds of movements?
hinge movement aka flexion and extension
37
which joints allow for pronation and supination?
ulna-radius joints
38
What is the proximal radioulnar joint?
- between the ulna and radius at the proximal end - loose (allows for pronation-supination) - rotates at top so radius can cross over the ulna
39
What is the distal radioulnar joint?
- between the ulna and radius and the distal end - head of radius crosses over
40
In anterior and anatomical position: Name the carpools in order from proximal to distal
1. Scaphoid (p) 2. Lunate (p) 3. Triquetrum (p) 4. Pisiform (p) 5. Trapezium (d) 6. Trapezoid (d) 7. Capitate (d) 8. Hamate (d)
41
How many carpals do we have?
8
42
What does "Stop Letting Those People Touch The Cadavers Hand" stand for?
Scaphoid, Lunate, Triquetrum, Pisiform, Trapezium, Trapezoid, Capitate, Hamate
43
What is the wrist joints?
- Where the radius/ulna meet carpals - Not within the carpals
44
How many metacarpals do we have?
5
45
which way do we name the metacarpals?
thumb to pinky
46
What makes up the metacarpals? order proximal to distal
- base - shaft - head
47
What do we call out fingers?
phalanges, phalanx
48
which digits have a middle phalanx?
digits 2-5
