PCB 2099 Lecture Notes - Lecture 25: Bronchus, Collagen, Fibrocartilage
Document Summary
Cartilage consist of cells called chondryocytes, which imparts strength and elasticity to the tissue. Connective tissue is characterized by abundant amounts of extracellular material, or matrix. Tissue proper tissues with a somewhat loose flexible matrix. Mesenchyme undifferentiated tissue found primarily during embryonic development. Bone cells are surrounded by an extremely hard matrix impregnated with calcium phosphate. Blood contains abundant extracellular material that suspends and transport the blood cells. Hyaline cartilage most abundant. it has a clear matrix that stains a uniform blue. Found: articular surfaces of bones, trachea, bronchi, nose. Fibrocartilage reinforce with collagen fibers to resist compression. Elastic cartilage contains abundant elastic fibers for flexibility. Nervous tissue consist of two major types of cells, nerve cell and neuroglial cell. Neuron a cell body with nucleus, capable of producing and conducting electrical impulses and releasing chemicals from the endings of the axon. Axon or nerve fiber neuron"s single long extension.
