BIOB10H3 Lecture Notes - Phagocytosis, Endothelium, Multinucleate
Document Summary
Cell specializations: flagella mts and mt motors (atpase, # of mitochondria atp, sperm receptor fertilin integrin protein, acrosome secretory lysosome secreted via kinesin along mts, small cell with condensed streamlined head . Function: packed with mrna (for transcription factors, etc) for early development, will initiatecell division shortly after fertilization, can bind sperm. Cell specializations: big cell, # ribosomes translation, integrin binds to fertilin, cell division mitotic spindle, contractile ring, coating- secretes protective proteins on outside. Function: early in development: send out migratory axons towards target cells (synapses) After differentiation: nerve impulses and formation and secretion of secretory vesicle. Cell specializations: cell migration machinery integrins, actin, Arp2/3: nerve impulses na+/k+ pump, channels, etc, # mitochondria - atp, secretion machinery mts (+maps) and kinesin, neurofilaments, actin & myosin v. Function: provides a continuously renewing, strong, waterproof surface to protect body from environment- function in wound healing. Cell specializations: hemi-desmosomes integrin attachment to basement membrane (with plectin & if"s)
