Flashcards in BRS-HISTO CH7 "Cartilage and Bone Deck (58)
is an avascular specialized fibrous connective tissue
what has chondrocytes in its matrix
what functions primarily to support soft tissues and assist in the devel- opment and growth of long bones.
is the most abundant cartilage in the body and it also serves as a temporary skeleton in the fetus until it is replaced by bone.
Matrix of Hyaline Cartilage has what in it?
- type 2 collagen
matrix that is adjacent to chondrocytes is called
is a layer of dense, irregular connective tissue that surrounds hyaline cartilage except at articular surfaces.
what provides the nearest blood supply to the avascular cartilaginous tissue.
manufacture the cartilage matrix through which nutrients and waste materials pass to and from the cells, respectively.
are mature cartilage cells that are embedded within lacunae in the matrix.
what has type 2 collagen eslatic fibers and has a present perichondrium?
location of hyaline cartilage
end of long bones
location of elastic cartilage
location of fibrocartilage
meniscus of knee
histogenesis of hyaline cartilage happens how
results from cell division of preexisting chondrocytes. This type of growth occurs only during the early stages of cartilage formation and in articular car- tilage and the epiphyseal plates of long bones.
results from differentiation of chondrogenic cells in the peri- chondrium. This type of growth results in the formation of chondroblasts and/or new chondrocytes, which elaborate a new layer of cartilage matrix at the periphery.
degeneration of hyaline cartilage happens how
chondrocytes undergo hypertrophy ad die, also the matrix calcifies
arthritis is an example of
degeneration of hyaline cartilage
It is a specialized type of connective tissue with a calcified extracellular matrix in which characteristic cells are embedded.
functions to protect vital organs, support fleshy structures, and provide a calcium reserve
bone matrix consists of
inorganic (calcified) portion of bone
organic portion of bone
about 65% of dry weight
inorganic portion of bone
about 35% of dry weight
organic portion of bone
what is a layer of noncalcified connective tissue covering bone on its external
surfaces, except at synovial articulations and muscle attachments.
what is a thin specialized connective tissue that lines the marrow cavities and supplies osteoprogenitor cells and osteoblasts for bone growth and repair.
These cells are derived from osteoprogenitor cells under the influence of members of the bone morphogenic protein (BMP) family and also transforming growth factor
These spindle-shaped cells are derived from embryonic mesenchyme and are located
in the periosteum and the endosteum.
what are capable of differentiating into osteoblasts
