ANA 109 EXAM 3 STUDY GUIDE
Osseous tissue - Answers - (bone tissue) the major structural and supportive connective
tissue in the body
2 types of osseous tissue - Answers - compact bone and spongy bone
Bone Marrow - Answers - soft fatty tissue found in cavities of bones
red bone marrow - Answers - site of blood cell production
yellow bone marrow - Answers - fat storage
epiphyseal lines - Answers - remnants of the growth plate where bone growth took
place earlier in life
endosteum - Answers - membranous lining of the hollow cavity of the bone
nutrient artery - Answers - large artery that enters compact bone near the middle of the
diaphysis
periosteum - Answers - a dense layer of vascular connective tissue enveloping the
bones except at the surfaces of the joints.
medullary cavity - Answers - cavity within the shaft of the long bones filled with bone
marrow
Epiphysis - Answers - the end part of a long bone, initially growing separately from the
shaft.
metaphysis - Answers - growth zone between the epiphysis and the diaphysis during
development of a long bone
Diaphysis - Answers - shaft of a long bone
perforating fibers (Sharpey's fibers) - Answers - thick bundles of collagen that extend
from the periosteum into the bone extracellular matrix
Humerus/Femur - Answers - example of long bone
long bone - Answers - bones that are longer than they are wide
Cuboid/scaphoid - Answers - examples of short bones
, short bones - Answers - bones that are equally long and wide
Parietal Bones - Answers - example of flat bones
flat bones - Answers - bones that are thin, broad, and commonly curved
Patella - Answers - Example of a sesamoid bone
sesamoid bones - Answers - bones that are small, flat and oval-shaped. found within
tendons
vertebra - Answers - example of an irregular bone
irregular bones - Answers - bones that do not fit any other category
depressions - Answers - varying depth in bone
types of depressions - Answers - facet, fossa, or groove
openings - Answers - holes that allow blood vessels and nerves to travel through a bone
types of openings - Answers - canal, meatus, fissure, or foramen
projections - Answers - bony extensions of varying shapes and sizes
types of projections - Answers - condyle, crest, protuberence, trochanter, line, process,
spine
osteoblasts - Answers - forms and deposits bone matrix. Can grow from cuboidal to
columnar
osteoclasts - Answers - resorbs bone
osteocytes - Answers - maintains bone tissue, trapped in their lacuna
bone-lining cells - Answers - lines all non-remodeling bone surfaces
Breakdown on extracellular matrix - Answers - Inorganic-65%
