Classification & Function: 10
How many bones are in the
human skeleton?
Answer: 206 named bones
Classification & Function: 20
What are four shapes that
bones are classified into?
Answer: Long, short, flat &
irregular bones
Classification & Function: 30
Name 3 of the 5 functions of
bones.
Answer: Support, protection.
Movement, Mineral & growth
factor storage, blood cell
formation
Classification & Function: 40
Which bones belong to the
appendicular skeleton?
Answer: Bones of upper &
lower limbs and the girdles
(shoulders & hips)
Classification & Function: 50
What is hematopoiesis and
where does it occur?
Answer: Blood cell formation. Occurs in the
marrow cavities of certain bones
Bone Structure: 10
A
Proximal Epiphysis
B
Diaphysis
C
Identify the
structures
labeled on the
picture.
Distal Epiphysis
(Be sure to use the
Articular cartilage
letters)
D
Bone Structure: 20
1. What membrane covers the
outside of bone?
Answer: Periosteum
2. What membrane covers the
inside of bone and trabeculae?
Answer: Endosteum
Bone Structure: 30
Draw a cross section of an
osteon and label the following
structures:
Lamella
Osteocyte
Central Canal
Bone Structure: 40
What are the organic
components of bone?
Answer: cells (osteogenic,
osteoblasts, osteocytes &
osteoclasts) and osteoid.
Bone Structure: 50
What is diploë?
Answer: The spongy bone in
flat bones
Bone Development: 10
What is ossification?
Answer: the process of bone
formation
Bone Development: 20
Before week 8, the skeleton is
made of fibrous membranes
and hyaline cartilage?
Why?
Answer: They are flexible & resilient
and can accommodate mitosis
Bone Development: 30
Which bones are formed
through intramembranous
ossification?
Answer: A membrane bone,
cranial bones of the skull and
the clavicles
Bone Development: 40
Once ossification is complete in
a long bone, what two
locations still have hyaline
cartilage?
Answer: on the epiphyseal plate and
articular cartilages
Bone Development: 50
Which hormone stimulates
epiphyseal plate activity during
infancy and childhood?
Answer: Growth Hormone
Remodeling & Repair: 10
Bone remodeling involves two processes
(bone deposit and
bone resorption).
What two factors control when/where
these processes occur?
Answer: Negative feedback hormonal
mechanism, maintains Ca+2 homeostasis in
blood. The othere responds to gravitational
& mechanical forces acting on skeleton
Remodeling & Repair: 20
Which hormone is released
when calcium levels in the
blood decline?
Answer: Parathyroid Hormone
(PTH)
Remodeling & Repair: 30
Comminuted fractures are more
common in _____ while
_____ fractures are common in
children.
Answer: Aged, Greenstick
Remodeling & Repair: 40
Draw a quick sketch of a long bone
being loaded (stressed) that
shows why they can “hollow out”
to make the medullary cavity.
Answer: see p. 190
Remodeling & Repair: 50
Write the type of fracture to match
the descriptions;
1. Bone ends are out of alignment.
a)
Displaced fracture
2. Bone broken through.
a)
Complete Fracture
3. Orientation of break is parallel to long
axis of bone.
a)
Linear fracture
4. Bone ends penetrate skin.
a)
Open (compound) fracture
Random!: 10
What are the functions
osteoblasts and osteoclasts?
Answer: Bone builders,
destroyers
Random!: 20
What is the function of
Sharpey’s fibers?
Answer: Connects periosteum
to bone
Random!: 30
How is red marrow and yellow marrow
different?
Answer: The difference between red and yellow
bone marrow is the function that they carry out.
Red bone marrow produces blood cells, is active
and divides cells. Yellow bone marrow is the
producer of blood cells during an emergency, is
inactive and contains fat.
Where do you find yellow marrow?
Answer: Medullary cavity
Random!: 40
What are the three types of
cartilage?
Answer: Hyaline, Elastic,
Fibrocartilage
Circle the one that is most
abundant.
Random!: 50
What are three common
treatments and/or
preventative measures against
osteoporosis?
Answer: Calcium & Vitamin D
supplements, weight bearing
exercises & hormone replacement
therapy
