King Edward Medical University, Lahore, Pakistan. Exam 1 Study. chapters 1-5. 2. The cytoplasm includes all material inside the cell membrane except for_____.. 3. Nucleus. 4. Which elements make up 90% of your body’s mass?. 5. Carbon. Most cells synthesize and secrete materials that are external to the plasma membrane. These extracellular structures include:. Cell walls of plants. The extracellular matrix (ECM) of animal cells. Intercellular junctions. Surface markers. Structure: Variable, integral proteins or glycolipids in plasma membrane. Function: Identify the cell. Example: MHC complexes, blood groups, antibodies. Septate junctions/tight junctions. By Sonia Trejo and Hailey Scoggins. Tight Junctions. At tight junctions the plasma . membranes of neighboring cells are . very tightly pressed against each . Other. . Bound together by specific . proteins (purple).. Assistant professor of pathology.. Faculty of Medicine. Pathology Department. 1. 2. Cellular . Adaptation. to Injury. A new steady state which lies between normal unstressed cell, and the injured overstressed cell, in which the cell can function and preserve viability.. presented by. Suman.Thota. M.Pharm .

Where does the name “cell” come from?. “Cells” were named by Englishman Robert Hooke in 1665.. He observed that cork wood looked like monk’s cells in a monastery.. The Cell Theory. The cell is the basic unit of structure and function.. 2. . The ECM of animal cells • Animals cells lack the structure and support that a cell wall provides • Have an ECM instead that provides some of the same support. 3. . Components of the ECM • Cells secrete . 1. 2. Peroxisomes. Peroxisomes. = Membrane-bound organelles that contain specialized teams of . enzymes . for . specific metabolic pathways; all contain . peroxide-producing . oxidases. .. • Bound by a single membrane. All living things including plants, animals, birds, insects, humans need energy for the proper functioning of cells, tissues and other organ systems. As we are aware that green plants, obtain their Course code (MBBS) . : Tissues 1. Course code (BMS) . : BCT-L4 . Tissues 1: Cellular Organisation of Tissues. Dr Peter Clark, NHLI, SAFB, SK. Multicellular organisms are made up of a wide variety of different cell types..
