ribs 1 - 7 - vertebrosternal - true ribs

Question 5

Which structure on the humerus crosses the distal end of the deltoid tuberosity?

Answer 5

radial groove

Question 6

Which carpal bone lies medial to the scaphoid and also articulates with the radius?

Answer 6

lunate

Question 7

Which pelvic girdle structure is described as a roughened area superior to the auricular surface?

Answer 7

iliac tuberosity

Question 8

Which structure on the femur marks the edge of the proximal articular capsule on the anterior surface of the femur?

Answer 8

intertrochanteric line

Question 9

A totally, rigid, immovable joint, which is created when two bones fuse and the boundary between them disappears, is called a(n) ___________.

Answer 9

synostosis

Question 10

Which statement regarding synovial joints is true?

• Synovial joints are amphiarthroses.
• Any mobile diarthrosis will be damaged by movement beyond the normal range of motion.
• Synovial joints are very mobile and are generally stronger than synarthroses.
• Synovial joint capsules are highly flexible, to allow free movement between the bones involved.

Answer 10

***Any mobile diarthrosis will be damaged by movement beyond the normal range of motion.

• Synovial joints are amphiarthroses. (diarthrosis)
• Synovial joints are very mobile and are generally stronger than synarthroses. (not stronger than synarthrosis - because they’re mobile)
• Synovial joint capsules are highly flexible, to allow free movement between the bones involved. (joint capsules???)

Question 11

An example of a pivot joint is the joint between _________________.

Answer 11

atlas and axis (or proximal radioulnar joints)

Question 12

Flexion at the ankle joint and elevation of the sole is an example of which of the following?

Answer 12

dorsiflexion

Question 13

The movement in which the anterior surface of a limb turns toward the long axis of the trunk is called _________.

Answer 13

medial rotation (also internal or inward rotation)

Question 14

Which of the following is NOT considered a joint of the axial skeleton?

Answer 14

pubic symphysis

Question 15

Which of the following primary vertebral ligaments connects the laminae of adjacent vertebrae?

Answer 15

ligamentum flavum

Question 16

Which fibrous-cartilaginous structure of the shoulder joint increases the actual extent of the joint cavity?

Answer 16

glenoid labrum

Question 17

Which ligament is at risk for injury if the knee is hyperextended?

Answer 17

fibular collateral ligament

Review the knee joint structures, and note that at full extension, a slight lateral rotation of the tibia tightens the ACL and “locks” the knee joint in the extended position. Lateral stability is provided by the fibular (PCL) and tibial (MCL) ligaments.

Question 18

Which statement regarding degenerative joint disease (DJD) is FALSE?

• It may result from the cumulative effects of wear and tear at joint surfaces.
• It is also known as osteoarthritis.
• It is not primarily caused by genetic factors.
• It generally affects individuals aged 60 years or older.

Answer 18

• It is not primarily caused by genetic factors.

Osteoarthritis can result from the cumulative effects of the wear and tear at joint surfaces or from genetic factors affecting collagen formation.
