Portage A&P1 Module 4 Exam
1. What two bones meet at the glenohumeral joint?
2. In your own words, why is this joint prone to dislocation? - ANS-1. Humerus and scapula
2. The structure of the shoulder permits movement of the arm in almost any direction but
provides little stability. The glenohumeral joint is prone to dislocation because it is held in
place primarily by muscular and ligament attachment with very little bony stability.
\A patient has a diagnosis of osteoporosis. (1) In your own words, describe this diagnosis
and (2) What type of bone cell would they be lacking? Explain your answer. - ANS-(1)
Osteoporosis is a bone tissue disease. When bone tissue degenerates faster than is
replaced, the bones become weak. Brittle bones cause increased pain and are more likely to
fracture.
(2) They would have decreased osteoblasts which are responsible for bone repair. The bone
repair would be unable to keep up with the ongoing breakdown of bone which is done by the
work of osteoclasts.
\Endochondral ossification: - ANS-F. both B and C
(begins at the primary ossification center at the center of long bones/is the formation of long
bones from hyaline cartilage)
\Label the bones in the figure below:
A: ____________B: ____________C: ____________D: ____________E: _____________ -
ANS-A. pisiform
b. hamate
c. capitate
d. trapezoid
e. trapezium
\Label the following bone landmarks:
B: ____________D: ____________E: _____________H: _____________I:
______________ - ANS-B. supraspinatous fossa D. acromion E. neck H. lateral border I.
inferior angle
\Label the following bones in the figure below:
A: ___________C: ___________E: ___________F: ___________G: ___________ - ANS-A:
1st Metatarsal Hallux
C: Lateral Cuneiform
E: Medial Cuneiform

G: Talus
\Label the following bones of the skeleton from the figure below:
2: ____________4: ____________6: ____________7: ____________8: ____________ -
ANS-2. nasal bone
4. zygomatic bone
6. inferior nasal concha
7. maxilla
8. mandible
\Label the following vertebrae as: - ANS-A. cervical
\Label the following vertebrae as: - ANS-B. thoracic
