Bones

Question 1

carpal bones

Answer 1

Proximal row :
Scaphoid/ Lunate
Triquetrum. Pisiform (like a pea)
Distral row :
Hamate/ Capitate/ Trapezoid/ Trapezium

Question 2

what is located at the top of the glenoid fossa?

shoulder

Answer 2

supraglenoid tubercle

Question 3

what attaches to the glenoid cavity?

shoulder

Answer 3

glenoidal labrum

this is a fibrocartilaginous rim that deepens the glenoid cavity. It is a continuum of the biceps brachii (long head)

Question 4

what can you find at the base of the coracoid process, and what structure passes through?
(shoulder)

Answer 4

the suprascapular notch.
The suprascapular nerve passes through. Formed by C5-C6 roots, and innervates the suprascapularis and infrascapularis muscles.

Question 5

What is located below the glenoid fossa, and what structure originates here?
(shoulder)

Answer 5

infraglenoid tubercle.

Origin of the long head of the triceps brachii

Question 6

what bones make up the thumb saddle joint?

Answer 6

I metacarpal and the trapezium

Question 7

what is the name of the articular surface on the humerus that articulates with the radius?

Answer 7

capitulum

Question 8

On the posterior of the humerus is the olecranon fossa, what is found anteriorly?

Answer 8

coronoid fossa

- this receives the coronoid process of the ulnar bone during forearm flexion

Question 9

What attaches to the greater tubercle?

humerus

Answer 9

supraspinatus
infraspinatus
teres minor

Question 10

what attaches to the lesser tubercle?

humerus

Answer 10

subscapularis

Question 11

what carpal bones does the scaphoid articulate with?

Answer 11

trapezium (joins to metacarpal I to form the saddle joint), and the trapezoid.

Question 12

what other bone forms the lunate column?

Answer 12

capitate

Question 13

what makes up the ulnar triquetral column?

Answer 13

triquetrum and hamate

Question 14

what is the pisiform bone?

Answer 14

the pisiform is regarded as a sesamoid bone embedded in the tendon of the flexor carpi ulnaris.

Question 15

what type of joint is the pubic symphysis?

Answer 15

a synarthrotic joint (synchondrosis, fibrous cartilage) and has almost no motion potential

Question 16

what type of joint is the sacroiliac joint?

Answer 16

synovial joint
(hyaline cartilage on sacrum, fibrocartilage on pelvic surface)
