deep to the loose connective tissue is _____ such as found in the deepest layer of both the dermis and lamina propria
dense connective tissue
the dense connective tissue in both the dermis and lamina propria is also considered the?
dense layer
the immature connective tissue is considered _____ and has few fibers and an increased amount of blood vessels
granulation tissue
most tissue of the body undergoes _____ as the individual cells die and are removed from the tissue and new ones take their place
regeneration
is the time it takes for the newly divided cells to be completely replaced throughout the tissue
turnover time
is fatty tissue that is found beneath the skin around organs and various joints and in regions of the oral cavity
adipose connective tissue
has a large number of elastic fibers in its matrix, which combines strength with elasticity, such as in the tissue of the vocal cords

chrondrocytes
only a small space surrounds the chondrocyte within the cartilage matrix
lucuna
is the most commone type found in the body and contain only collagen fibers as part of its matrix
hyaline cartilage
is simliar to hyaline except that it has numerous elastic fibers in its matrix in addition to it numerous collagen fibers

ossification
is formation of osteoid between two dense connective tissue sheets, which then eventually replaces the outer connective tissue

occurs in a specific area of a bone as a result of infection, altered mechanical stress, or pressure on the bone so that it adapts by removing bone tissue
localized resorption
occurs over the entire skeleton in varying amounts because of endocrine activity to increase blood levels of calcium and phosphate needed by the body
generalized resoprtion
resting lines, appear as smooth lines between the layer of bone because os osteoblasts having rested formed bone and then rested again after appositional growth
