| Question | Answer |
|---|---|
| Hierarchy life order | subatomic particle, atom, molecule, organelle, cell tissue, organ, organ system, organism, population, environment, and biosphere |
| Embryonic germ layers | outtermost ectoderm middle - mesoderm inner most - endoderm |
| Ectoderm gives rise to | Nervous tissue and some epithelial tissue |
| mesoderm gives rise to | connective tissue, muscle tissue and some epithelial tissue |
| Endoderm gives rise to | epithelial tissue |
| What are the Primary tissue types | epithelial, connective, muscle and nervous |
| what are the types of connective tissue | Dense, loose, cartilage, bone (osseous), blood, and lymph |
| Types of Dense Connective tissue | regular irregular elastic |
| types of loose connective tissue | areolar adipose reticular |
| Types of cartilage connective tissue | hyaline fibro elastic |
| types of bone osseous connective tissue | dense/compact spongy |
| Connective tissue is highly what and expect for | Highly vascular cartilage is the only one that is not vascular |
| what is plasma | liquid portion |
| what are the type of cells | erythrocytes thrombocytes leukocytes |
| What are erythrocytes | They lack a nuclei transport o2 |
| What are thrombocytes | platelets form clots |
| what are leukocytes | white blood cells |
| Leukocytes that are granulocytes | neutrophils (aka polymorphonucleated leukocyte) 3-7 looks acidophils (aka eosinophil) basophils |
| Leukocytes that are agranulocytes | monocytes lymphocytes |
| what are the mature cells in cartilage connective tissue and where is it found | CHONDROCYTES |
| Types of protein fibers in connective tissue | Thick - collagen (linear or wave) Thin - Elastic and reticular (small fragments) |
| type of protein fibers in Hyaline cartilage connective tissue | No protein fibers seen |
| type of protein fibers in fibro cartilage connective tissue | collagen fibers |
| type of protein fibers in areolar cartilage conn tissue | both collagen and elastic fibers |
| type of protein fibers in reticular cartilage conn tissue | reticular protein fibers |
| what is adipose loose connective tissue | adipocytes, used to store triglyceride. has peripheral nuclei |
| Regular dense conn tissue | a lot of collagen fibers (cymetric |
| Irregular dense conn. tissue | mosaic asymmetric, has fibroblack (spindle- shaped) |
| Skeletal muscle tissue | no branching. multinucleated and the nuclei are peripheral (pushed to the edge) |
| Smooth muscle tissue | only does not have striations, no branching, spindle shaped. |
| cardiac muscle tissue | heavy branched, may see intercalated discs |
| which muscle tissue is voluntary and which is involuntary | vol - skeletal invol - smooth, cardiac |
| Nervous tissue cells | neuroglia - supoprting cells neurons - signal |
| parts of a neuron | dendrite which is connected to the soma (cell body), axon, and then ends on axon endings |
| What type of leukocytes are phagocytes | neutrophils highly phagocytic acidophils - somewhat macrophages |
| what is the difference between monocytes and macrophages | when monocytes are in a blood vessel they are not phagocytic when it leaves the blood vessel that is when that become macrophages and phagocytic |
| characteristics of Epithelial tissue or epithelium | avascular lining tissue classified based on # of layers and shape of cells |
| 1 layer of epithelial tissue is called | simple |
| greater then 1 layer of epithelial tissue is called | stratified |
| Can two avascular be next to see other | no because there is not enough blood supplyo |
