How can diaphysis be described

the shaft of a long bone

calcitriol acts on which organs to raise blood calcium levels

1. bones 2. kidneys 3. small intestines

which two ions are deposited by osteoblast into the bone matrix

1. calcium 2. phosphate

what are the two terms associated with the myeloid tissue

1. hemopoietic tissue 2. red bone marrow

True or False Spongy bone is primarily made up of osteons

False

bone tissue comprised of trabeculae is called what

Spongy bone and it is also called cancellous

when braces apply stress to the teeth causing remodeling of the jaw bones, this an example of

Wolff's law of bone

how is the medullary cavity best described

a hollow cavity within the diaphysis of a long bone

which of the following describes the structure of a flat bone

a layer of spongy bone is sandwiched between two layers of compact bone

where is red bone marrow found in the bones of a child

almost all bone

what describes a nutrient foramen

an opening into the surfaces of a bone which allows the passages of blood vessels into bone tissue

within compact bone, a central canal is found at the center of which structure

an osteon

which type of bone growth involves the deposition of new tissue on the surface

appositional

what is the function of red bone marrow

blood cell production

in osseous tissue, the narrow channels connecting neighboring lacunae are called

canaliculi

what is the name for a channel that extends vertically through the center of an osteon

central canal

what is a former chondroblast that has become enclosed within a lacuna in a cartilage

chondrocyte

which of the following best describes perforating fibers

collagen fibers from the periosteum that firmly adhere the periosteum to the bone

which osseous tissue is found on the surface of bones and composed of tightly arranged parallel osteons

compact

bone tissue made up of parallel osteons that are tightly packed together is called

compact bone

the layers of bony matrix arranged around the central canal of an osteon are called

concentric lamellae

what is the term for the bone tissue located between the two layers of compact bone is the skull

diploe

the layers of reticular connective tissue lining internal surfaces of a bone is called

endosteum

the structure found between the epiphysis and diaphysis in a child and is a cite of bone growth is the

epiphyseal plate

what is the expanded end of a long bone to which tendons and ligaments attached called

epiphysis

True or False Osteoclast are not needed for bone remodeling

false

True or False Osteocytes and osteoclasts develop from the same type of bone marrow stem cells

false

True or false an athlete will have a lower bone density than a couch potato

false

bones are classified as one of four types based on their shape. the bone of the cranium are examples of

flat bones

bones that have a broad curved shaped are classified as what

flat bones

what is the function of the osteogenic layer of the periosteum

growth and healing

what is another name for central canal

haversian canal

what is blood cell formation called

hemopoiesis

articular surfaces are covered with which tissue

hyaline cartilage

the inorganic matter that is about 85%

hydroxyapatite

if a patient has abnormally high blood calcium levels, they are said to have a condition called

hypercalcemia

what does the hormone calcitonin do

inhibits osteoclasts and stimulates osteoblasts

an increase in the length of a bone occurs by the process of

interstitial growth

partial older osteon can be found between complete newer osteons. these partial osteon are referred to as

interstitial lamellae

bones that have elaborate shapes are classified as

irregular bones

what are the layers of bony matrix in compact bone tissue called

lamellae

bones that are longer than they are wide are classified as

long bones

the transitional area between the shaft and the cartilaginous head of a developing long bone is called

metaphysis

the process of bone formation is called

ossification

which bone cells produce the soft organic bone matrix

osteoblast

as spongy bone is produced by intramembranous ossification, which cells reabsorb and remodel the forming bone

osteoclast

bone dissolving cells on bone surfaces are called

osteoclast

stem cells in developing bone that give rise to osteoblast are called

osteogenic cells

during intramembranous ossification, osteoblast secrete a soft collagenous tissue know as

osteoid tissue

a hormone is secreted and produced by a the parathyroid glands

parathyroid hormone

a low blood calcium level stimulates the release of which hormone

parathyroid hormone

which channel run perpendicular to the central canals of osteons

perforating canals

the connective tissue surrounding the external surface of a bone is called

periosteum

in adults, which bone marrow is limited to the axial skeleton, pectoral and pelvic girdles and proximal heads of the humerus and femur

red bone marrow

what is the process of dissolving bone and releasing minerals into the blood called

resorption

the interior of flat bones is composed of what bone

spongy bone

which structures found in spongy bone line up along the bone's lines of stress

trabeculae

true or false Once "closed" or ossified, growth in length no longer occurs at an epiphyseal plate

true

fatty bone marrow that no longer produces blood is called

yellow bone marrow
