What does the patella articulate with?

Answer 18

• articulates with FEMUR (patellar surface)

- not tibia

Question 19

What is the role of the patella?

Answer 19

prevents rubbing of muscle tendon against distal femur

Question 20

• tibia
• talus
• calcaneus

Question 23

function of glenoid cavity of the scapula?

Answer 23

articulates w/ humerus to form glenohumeral joint

Question 24

what part of the scapula forms the bony tip of the shoulder?

Answer 24

acromion of the scapula

Question 25

which bones does the clavicle articulate with?

Answer 25

• manubrium (sternum, medially)

- acromion (scapula, laterally)

Question 26

what bone of the humerus articulates with what bone of the ulna?

Answer 26

trochlea of the humerus articulates with the trochlear notch of the ulna

Question 27

what bone of the humerus articulates with what bone of the radius?

Answer 27

capitulum (humerus) articulates with the head of the radius

Question 28

what are the two articulations on the humerus that form a joint, and what joint?

Answer 28

trochlea and capitulum join with the ulna and radius to form the elbow joint

Question 29

what does the head of the humerus articulate with?

Answer 29

glenoid cavity

• forms glenohumeral joint

Question 30

What bone of the femur articulates with what bone of the coxal bone?

Answer 33

lateral malleolus of the fibula

Question 34

what bone of the foot forms a joint with the tibia? what is the joint?

Answer 34

the talus of the foot (tarsals) articulates with the tibia and fibula to form the ankle joint
