Questions
How are the pectoral and pelvic girdles
structurally different? How is this difference
reflected in their
functions?
Answer: The pectoral girdle moves freely across the
thorax and allows the upper limb a high degree of
mobility, while the pelvic girdle is secured to the axial
skeleton to provide strength and support.
Which are the four major sutural bones
and between which bones are they
found?
Answer: 1. Coronal parietal
and frontal
2. Sagittal between
the parietal bones
3. Squamous parietal
and temporal
4. Lambdoidal parietal
and occipital
If the hyoid bone is not attached to another
bone why is it so important?
Answer: The hyoid acts as an attachment point for muscles
in the throat region to connect the muscles in the
lower jaw region. It allows for the muscles to make a right
angle at the junction of the lower jaw and
throat. The hyoid serves as a movable base for the tongue
and its horns are attachment points for neck
muscles that raise and lower the larynx during speech and
swallowing.
What is the purpose of the articular
processes of the vertebrae?
Answer: These processes (superior and inferior) allow
the vertebral column to flex forward some, but lock the
vertebrae if the column is flexed back. In a fourlegged
animal, such as a horse, these processes allow
the back to remain in place while you ride it.
1. List four groups of bones based
upon their shapes, and name an
example from each group.
a. Long bones—femur and humerus
b. Short bones—tarsals and carpals
c. Flat bones—ribs, scapulae, and bones
of the skull
d. Irregular bones—vertebrae and many
facial bones
Sketch a typical long bone, and label its
epiphyses, diaphysis, medullary cavity,
periosteum, and articular cartilages.
See figure 7.2, page 183.
3. Distinguish between spongy and
compact bone. Compact bone is
comprised of tightly packed tissue that is
strong, solid, and resistant to bending.
Spongy bone consists of numerous
branching bony plates.
Irregular interconnected spaces occur
between these plates, thus reducing the
weight of the bone.
Explain how central canals and perforating
canals are related. Central canals
(Haversian canals) contain one or two small blood
vessels and a nerve, surrounded by loose
connective tissue. These vessels provide
nourishment for the bone cells associated with the
osteonic canals. The osteonic canals run
longitudinally. Perforating canals (Volkmann’s
canals) run transversely and contain larger blood
vessels and nerves by which the vessels and
nerves in osteonic canals communicate with the
surface of the bone and the medullary cavity.
Distinguish between osteoblasts and
osteocytes. Osteoblasts are boneforming cells. Osteocytes are mature bone
cells surrounded by matrix.
Explain the function of an epiphyseal
plate.
The epiphyseal plate is a band of
cartilage that is left between the primary
and secondary ossification centers. This
plate includes rows of young cells that are
undergoing mitosis and producing new
cells. As the epiphyseal plate thickens due
to the new cells, bone length is increased.
Describe the functions of red and yellow bone
marrow.
Red marrow functions in the formation of red blood
cells, white blood cells, and blood platelets. Its red
color is derived from the oxygen-carrying pigment
hemoglobin. Yellow marrow functions in fat storage
and is inactive in blood cell production
Distinguish between the axial and appendicular
skeletons.
The axial skeleton consists of the bones that make
up the skull, the hyoid bone, the vertebral column,
and the thoracic cage. The appendicular skeleton
consists of the pectoral girdle, the bones that
comprise the upper and lower limbs, and the pelvic
girdle.
