Bones Flashcards
Spongy bone
has a brace-like arrangement of trabeculae
Where does hematopoiesis occur?
flat bones
True/false: ligaments are considered part of the skeletal system
True
What bones form the most distal row of tarsals?
Cuboid
A bone of the face will develop by what kind of ossification?
Intramembranous
The most inferior part of the sternum is called the:
Xiphoid Process
What kind of bone is best for harvesting donor bone marrow?
Flat bone
A suture in the skull would be called a
synarthrosis
Encourages calcium deposition from blood into bone
Calcitonin
Stimulates osteoclasts to resorb bone and increase blood calcium
Parathyroid Hormone
Influences the basal metabolic rate of bone cells
Thyroid Hormone
Articular cartilage, found on the ends of long bones, consists of…
hyaline cartilage
Appositional growth requires…
deposition of external circumferential lamellae
hyaline cartilage…
forms articular cartilage, composes epiphyseal plates, attaches ribs to sternum
fibrocartilage…
weight-bearing cartilage, withstands compression, forms intervertebral discs
Compact Bone…
made up of osteons | visible, obvious, central canals | also called cortical bone
Spongy bone…
composed of trabeculae, spicules are common, convey strength with light weight, found in greater proportions in flat bones
Red bone marrow…
is hemopoietic, found in spongy bone areas and medullary cavities of children, found in the proximal epiphyses of the humerus and femur in adults, found in flat bones of the skull
yellow bone marrow
contains a fatty substance that can be used for energy, found in the medullary cavities of adult long bones
in the epiphyseal plate, the microscopic zone in which chondrocytes undergo rapid cell division and become aligned into longitudinal columns of flattened lacunae is called the…
zone of proliferating cartilage
the secondary ossification center in a long bone is located in the
epiphysis
what is the role of nerves that supply a bone
detect injuries in the bone
what increases blood calcium
osteoclastic activity, calcitriol, parathyroid hormone, increased bone resorption.
what decreases blood calcium
osteoblastic activity, calcitonin, increased use of sunblock
