PORTAGE A&P1 MODULE 4 EXAM WITH QUESTIONS AND
ANSWERS
1. What two bones meet at the glenohumeral joint?
2. In your own words, why is this joint prone to dislocation? - -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. - -(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: - -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: _____________ - -A. pisiform
b. hamate
c. capitate
d. trapezoid
e. trapezium
-Label the following bone landmarks:
B: ____________D: ____________E: _____________H: _____________I: ______________ - -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: ___________ - -A: 1st Metatarsal
Hallux
C: Lateral Cuneiform
E: Medial Cuneiform
F: Navicular
G: Talus
-Label the following bones of the skeleton from the figure below:
2: ____________4: ____________6: ____________7: ____________8: ____________ - -2. nasal bone
4. zygomatic bone
6. inferior nasal concha
7. maxilla
8. mandible
