Bone and Skeletal Tissues - created from Mind Map

Skeletal Cartilages Chondrocytes housed in lacunae in extracellular matrix Hyaline Elastic Fibrocartilages Large Amounts of water lacks nerve fibers Avascular Surrounded by fibrous perichondrium Appear glassy Collagenous fibers Most abundant skeletal cartilages Flexible and resilient Articular, costal, respiratory and nasal cartilages abundant elastic fibers w collagen fibers flexible Outer ear and epiglottis Thick collagen fibers most compressible cartilages resist stretching intervertebral discs and knee joint cartilages

Classification of Bones Long Bones Short Bones Flat Bones Irregular Bones
