Review Sheet Test 2This is to help you review the concepts and skills you should have learned at the end of this section. Thereis no guarantee this will cover all the test material, nor will all this material be on the test. But if you can do all of this, you should be in excellent shape for the test. This should be a guide for you as you re-listen to the lectures, review the review slides, go over the activities, practice the clicker questions, and review the quiz questions. Lesson 7 Animal Organization and Homeostasis ●Cell organization oA fertilized egg is called a EMBRYOoShortly thereafter, in the gastrula stage, cells will be sorted into 3 lineages that will develop into the different tissues in the body. These are GERM LAYERS; ENDODERM (STOMACH) , MESODERM (ORGANS AND MUSCLE) , ECTODERM (SKIN, HAIR, NERVOUS SYSTEM)oTissue types▪Know the 4 different tissue types▪Epithelial Tissue●What germ layers can it come from? ANY OF THE 3●What does it do? (2 main functions) COVERS SURFACES AND PROVIDES PROTECTIVE BARRIER●Understand the difference between squamous FLAT, cuboidal CUBE, andcolumnar COLUMN, simple SINGLELAYER OF CELLS and stratified epithelium SEVERAL LAYERS●What are some of the modifications found on epithelial cells? CILIA OR MUCUS SECRETING▪Connective Tissue●What germ layer(s) is it derived from? EMBRYONIC MESODERM●What defines ALL connective tissue? CELLS EMBEDDED IN AN EXTRACELLULAR MATRIX●What is connective tissue proper?oWhat are the 2 types? CONNECTIVE TISSUE PROPER AND SPECIAL CONNECTIVE TISSUEoWhat types of fibers would you find here? PROTEINFIBERS, COLLAGENAND ELASTICoWhat are examples of tissues in this category? LOOSE (LOOSE SCATTERING OF PROTEIN FIBERS AND IS FOUND BETWEEN SKIN AND ORGANS)AND DENSE (TIGHTLY PACKED COLLAGENFIBERS, TENDON, LIGAMENT, AND TOUGH COVERINGS OF ORGANS)oFat is in this category! ▪When fat is used up and made, do the number of cells or their size change? SIZE CHANGE▪What are the two main roles of fat? ENERGY STORAGE, INSULATION, CUSHION OF ORGANS
●What is special connective tissue?CARTILAGE AND BONESoWhat sort of examples that aren’t immediately recognizable as connective tissue fall under this category? BLOOD▪Muscle Tissue●What does muscle tissue specialize in? FOR CONTRACTION●What are the 3 types? SMOOTH, SKELETAL, AND CARDIAC●For each type, what are the main functions, what are some examples? SMOOTH- INVOLUNTARY CONTROL, LINES BLOOD VESSELS AND IRISSKELETAL- ATTACHED TO BONES BY TENDONS AND CAUSE MOVEMENT WHEN CONTRACTED, UNDER VOLUNTARY CONTROL DUE TO NERVOUS SYSTEM CONTROLLING CONTRACTIONSCARDIAC- FOUND ONLY IN HEART, INTERCONNECTED BY GAP JUNCTIONS WHICHENABLE THE CELLS TO CONTRACT AS A SINGLE FUNCTIONING UNIT, INVOLUNTARY●Which types have voluntary, involuntary control? VOLUNTARY- SKELETALINVOLUNTARY- SMOOTH AND CARDIAC▪Nerve Tissue ●What 2 cells make up nerve tissue? NEURONSAND NEUROGLIA●Which one sends electrochemical signals? Which one can’t?
