Accepted Answer

Right

Question 4

Which feature distinguishes the top from the bottom of the scapula?

Accepted Answer

The superior border is at the top; the inferior angle (pointed tip) is at the bottom

Question 5

In the tibia, which anatomical landmark is used to distinguish the anterior surface?

Accepted Answer

Tibial tuberosity

Question 6

A student is asked to identify the right vs. left coxal bone. Which orientation is correct for a right coxal bone?

Accepted Answer

Acetabulum faces laterally; pubic symphysis is medial/anterior

Question 7

Which of the following best describes the orientation of the maxilla when identifying top vs. bottom?

Accepted Answer

The alveolar process is at the bottom; the orbital rim and frontal process are superior

Question 8

A radiograph shows a tibia with the tibial tuberosity facing anteriorly and the medial malleolus pointing inward. Which side of the body is this tibia from?

Accepted Answer

Left

Question 9

Which of the following is a correct method for distinguishing anterior from posterior surfaces on bones, according to the teaching tips?

Accepted Answer

Rough spines and depressions are usually posterior

Question 10

A medical student is examining a scapula. If the glenoid cavity faces laterally and the scapular spine is posterior, which side of the body is the scapula from?

Accepted Answer

Right

Question 11

Which of the following best describes the orientation of the femur when determining top vs. bottom?

Accepted Answer

The head and neck are proximal; the condyles and patellar surface are distal

Question 12

A patient has a fracture at the infraorbital foramen. Which bone is affected, and what is the correct orientation for right vs. left?

Accepted Answer

Maxilla; infraorbital foramen is lateral

Question 13

Which anatomical feature is used to distinguish the top from the bottom of the coxal bone?

Accepted Answer

Iliac crest is superior; ischial tuberosity is inferior

Question 14

A student is asked to identify the right vs. left temporal bone. Which of the following is correct?

Accepted Answer

Mastoid process points down/back; external acoustic meatus is lateral

Question 15

Which of the following is the correct sequence for identifying a bone's orientation, according to the teaching tips?

Accepted Answer

Start with top vs. bottom, then medial vs. lateral, then anterior vs. posterior

Question 16

A radiologist is examining a humerus. If the head faces medially and the olecranon fossa (large depression) is posterior, which side of the body is the humerus from?

Accepted Answer

Right

Question 17

Which of the following is true regarding the orientation of the tibia?

Accepted Answer

The broad, flat condyles are at the proximal (knee) end

Question 18

A student is asked to identify the right vs. left maxilla. Which of the following is correct?

Accepted Answer
