Document Summary
Shaped depending on the purpose of the cell: tissue: A collection of cells that work together for a particular function: the cells are connected via cellular junctions, four types of tissues in animals: A functional structure with several tissues: ex. The cytoskeleton: creates different cell shapes, extra cellular matrix (ecm) Helps cells connect and work in harmony to perform a function. Monday, october 10, 2016: the epidermis is the epithelial tissue, the basal lamina is the ecm. Supports the epithelial tissues: the dermis is the connective tissue. The dermis also contains broblasts, adipocytes (fat cells), mechanoreceptors, and macrophages: dermis supports epidermis. What makes up the cytoskeleton: microtubules. Hollow tubes formed from tubulin dimers: alpha tubulin, beta tubulin. These two tubulins come together to form tubulin dimers. Dimers come together to form the microtubules. Centrosome: a compact structure that is the microtubule organizing center for. Help cels withstand compression and maintain cell shape.
