HUBS 191 FINAL EXAM ACTUAL QUESTIONS AND CORRECT ANSWERS WITH COMPLETE SOLUTION. 2024/2025 Name the four basic types of tissue Connective tissue, epithelial tissue, muscle tissue and nervous tissue. Why do the four types of tissues have different structures and function? They are made up of different kinds of cells. They have different things that make up the extracellular matrix. They have varying amounts of extracellular matrix. Types of connective tissue Connective tissue proper - Lo...

Extracellular Matrix (ECM) - -relatively stable structural material that lies under epithelia & that surrounds connective tissue cells -can be divided into 2 structural components: fibers & amorphous ground substance Fibers - -an aggregate of fibrils -1-10 um diameter (largest) -can be divided into collagen & elastic -each is comprised of specific types of proteins -can assemble into bundles Fibrils - -an aggregate of filaments (filaments put together = fibrils) -20-500nm diameter -col...
