DRAWING LAB HISTOLOGY: CONNECTIVE TISSUE

HW: PAGE 150 Find a Group of 4 to help you complete the Analysis & Review Questions! Each person should do 5 Questions. Decide who is doing which questions. Print 4 copies of answers. Bring to class tomorrow!

CONNECTIVE TISSUE: BACKGROUND Most abundant type of tissue. Epithelial tissue is more dense. Made up of: cells, fibers, and extracellular components Structure allows support, yet is pliable. Produced by fibroblasts.

EXAMPLES Blood Bone Cartilage Tendons Ligaments Adipose (fat) Lymph

EXTRACELLULAR PORTION OF CT Interstitial Fluid Fluid that contains proteins and cells Adhesion proteins Allow cells to bind to each other and to structural fibers. Proteoglycans Proteins that act to filter fluids through the ground substance. Collagen Extremely strong fibers that provide support Elastin Fibers that are able to stretch and return to their original shape, much like a rubber band. Reticular fibers Fine networking fibers

CONNECTIVE TISSUE TYPES

FUNCTIONS OF CT Protect Store Energy Support Transport Insulate Connect all body tissues

HIGHLY VASCULAR TO AVASCULAR Avascular tissues made up of extracellular (non-living) matrices, or substances, rather than cellular components

THREE TYPES OF CARTILAGE TISSUE

CT DISORDERS & DISEASE Collagen and Elastin most common components affected. May become injured through trauma (sprain) Or genetic or environmental factors cause problems. Own Immune system may cause inflammation.

SYMPTOMS Fatigue Fever Muscle Pain Stiffness Weakness Joint pain

CONNECTIVE TISSUE DISORDERS & DISEASE
