Tissues- Connective Flashcards
Five types of Connective Tissue
Areolar, Adipose, Cartilage, Bone, Dense
Two Components of Connective Tissue
Cells and Matrix
Matrix
structural proteins between cells; the ground substance (gel that fills the rest of the space)
Cells
located in hollow spaces called lacunae
Areolar
most common type; found beneath basement membrane; fibrous proteins running in random directions; made up of fibroblasts and white blood cells
Adipose
body storage for fat; primary cells are called adipocytes (leaves very little room for matrix)
Cartilagenous
found at the ends of most bone; also called hyaline cartilage; also found on most ribs, larynx, pharynx, and trachea; bones were originally composed of hyaline collagen makes up most of matrix; avascular
Hyaline Cartilage
one cell type is chondrocytes; chondrocytes are found in the lacunae, which produce collagen (makes up the majority of the matrix)
Bone (Osseous)
mostly made up of matrix, but calcium is embedded into it (unlike cartilage tissue); has hollow tubes called Haversion Canals
Haversion Canals
make way for blood vessels and they are surrounded by mature bone cells called osteocytes
Dense
found in tendons and ligaments; is firm but also stretchy; primarily contains fibroblasts as its cell type, and collagen as its main fiber; the collagen runs parallel to stretch better
