Portage BIOD151 Module 4 Questions and
Correct Answers, Complete Solution 100%
The skull is formed by___bones; the facial skeleton contains ___bones.
22;14
Function of flat bones
produce red blood cells; protection of internal organs. (skull protects the brain).
shape of long bones
long and thin; designed to support body weight and enable movement
Five basic bone shapes
flat, irregular, long, short and sesamoid
hollow chamber in bone, usually filled with air
sinus
what division of the skeleton lies along the midline?
axial
Sinusitis
inflammation of the sinuses
The sub-scapular fossa is located on what side of the scapula?
anterior
What does the head of the humerus articulate with?
the scapula
The glenohumeral joint is prone to dislocation. Describe dislocation and what
happens in dislocation of the glenohumeral joint.
Dislocation occurs when the bones of a joint are knocked out of place. The glenoid
cavity is extremely shallow and much smaller than the head of the humerus. The
humerus needs to be held to the shallow flenoid cavity by the rotator cuff muscles and
other ligaments.
Where is red bone marrow found?
found primarily in short and flat bones
where is the epiphysis of a bone found?
found at the ends of the long bones. contains the articular cartilage at joint articulations
endochondral ossification
begins at the primary ossification center at the center of long bones. Is the formation of
long bones from hyaline cartilage.
Describe osteoporosis and what type of bone cell the patient would be lacking?
Occurs when bone tissue degenerates faster than it is replaced. The bones become
weakened and brittle, bones cause pain and can fracture easily. Osteoblasts,
responsible for bone repair, would decrease meaning that bone repair would not be able
to keep up with the ongoing breakdown of bone.
Explain what it means to have a herniated disc and discuss one treatment option
to address pain
a herniated disc is an injury to the intervertebral disc where the center portion of the disc
bulges into the vertebral foramen causing pain. Physical therapy can assist with pain by
strengthening to support back ligaments.
