Connective Tissue Chart Mrs. Donohue

Blood Cells – start as blasts Erythrocytes Carry oxygen & carbon dioxide Leukocytes Monocytes – phagocytic Neutrophils-fight bacterial infections Lymphocytes – fight viruses Thrombocytes – clot blood

Bones L – osteocyte – cell Osteocyte cell come from osteoblasts Osseous Tissue

Connective Tissue Principal stem cell: fibroblast

Dense Connective - Tendons Regular Location: Connect muscle to bone Function: support and protection Avascular Point to fibers – run parallel to movement

Dense Connective - Ligaments Regular Location: Connect bone to bone Function: support and protection avascular

Dense Connective – Skin - Dermis irregular Location: Inside layer of skin Function: support and protection vascular

Loose Connective - Areolar Location: all through the body Function: binds skin to muscle Very vascular Provides nutrients to skin

Loose Connective – Adipose-fat Location: all through the body Concentrated beneath the skin Heart, kidneys, & mammary glands Function: protection warmth Food reserve (energy) nucleus

Loose Connective - Reticular Location: lymph nodes, liver, spleen, and bone marrow Function: phagocytic immunity

Connective – Cartilage Avascular Hard to get nutrition Condrocytes – make fibers

Connective – Cartilage: Hyaline Most abundant Location: end of bone Respiratory tract Rib cage Function: Support protection

Connective – Cartilage-Elastic Location: pinna (outer ear) Epiglottis Auditory canal Function: Flexibility strength

Connective – Cartilage - Fibrocartilage Matrix reinforced with collagen fibers Location: intervertebral discs Function: durable Withstand tension and compression reversable
