Cartilage, bone, blood, tissue

Description of cartilage

All cartilages have similar structural components

Firm, flexible tissue

Contains no blood vessels or nerves

Matrix contains up to 80% wate

Three types of cartilage tissue

Fibrocartilage

Hyaline cartilage

elastic cartilage

Main cells in the cartilage tissue are

Chondroblast: makes the Cellular matrix or ground substance

Chondrocyte: old chondroblast

Hyaline tissue

Imperceptible collagen fibers (hyaline = glassy

Function of Hyaline tissue

Supports and reinforces

Resilient cushion

Resists repetitive stress

Location of Hyaline tissue

Fetal skeleton

Ends of long bones

Costal cartilage of ribs

Cartilages of nose, trachea, and larynx

Description of Cartilage Elastic tissue

Similar to hyaline cartilage

More elastic fibers in matri

Location of Cartilage elastic

Supports external ear

Epiglottis

Function of cartilage elastic tissue

Maintains shape of structure

rFAllows great flexibility

Description Fibrocartilage

matrix similar but less firm than hyaline cartilage

Thick collagen fibers predominate

Function of fibrocartilage

Tensile strength and ability to absorb

compressive shock

Location of fibrocartilage

Intervertebral discs

Pubic symphysis

Discs of knee joint

Description of Bones tissue

Bone matrix contains

Inorganic calcium salts

Abundance of collagen fibers

Main cells of bones tissue

Osteoblasts: secrete collagen fibers and ground substance of the matrix

Osteocytes mature bone cells in lacunae well vascularized

Function of bones tissue

Supports and protects organs

Provides levers and attachment site for muscles

Stores calcium and other minerals

Stores fat

Marrow is site for blood cell formation

Location of bones tissue

Bones

Description of blood tissue

Red and white blood cells in a fluid matrix

Function of blood tissue

Function

Transport of respiratory gases, nutrients, and wastes

Location of blood tissue

Within blood vessels
