组织学重点 The histologic focus Noun explanation Endothelium: a flat, flat epithelium that is distributed in the cardiovascular and lymphatic surfaces Skin: flat epithelium in the parietal pleura, peritoneum, and pericardial surface Gland epithelium: epithelial tissue, which is primarily secretory 4. Molecular sieve: hyaluronic acid molecule chain connected to a lot of protein and polysaccharide molecules, has a lot of microporous molecular structure, can prevent the gap is greater than the molecular substances expand structure Blood: the appearance, number, proportion and hemoglobin content of blood cells and platelets in the clinic Can 6. Hematopoietic stem cells: proliferation and differentiation of all kinds of the most primitive hematopoietic cells, blood cells with strong proliferation ability and differentiation potential and self-renewal ability Muscle subsection: A segment of muscle fibers between adjacent Z lines, including 1/2I band + A + 1/2I, which is the structural and functional unit of myofibrils 8. Intercalated disc: myocardial fibers adjacent interconnected parts, then is a deep dyeing of thick line, with the long axis vertical or ladder shaped, muscle fibers can synchronize the myocardial fibers shrink as a function of the whole Triplets: the structure of the final pool on both sides of the cross tube 10. The blood - brain barrier: barrier exists between blood and brain tissue, by continuous capillary endothelial and endothelial basement membrane, astrocytes swelled the formation of glial membrane. Can restrict the structure of large molecules into the brain Synapses: communication between neurons or between neurons and effector cells Nerve fibers: a combination of axon or long dendrites and a small glial cell that is wrapped around it, conducting nerve impulses Heart conduction system: composed of special muscle fibers, including the sinus node, the atrioventricular node, the chamber bundle, and the left, right branch and purkinje fibers.
