The cell is the basic unit of life. It is a highly organized structure composed of numerous organelles, cytoplasm, cytoskeletal structures and surrounded by a plasma membrane. Each of these structures has their own specific functions that allow the cell to survive. In addition, cells need to communicate with each other. In multicellular organisms, cell to cell communication is necessary for development and function of organs and organ systems. Dysfunction of cellular components and/or cellular communication may not only affect the individual cell but may affect the entire organism resulting in a clinical disorder.
Respond to the two topics below for this unit’s Discussion. Then, throughout the week, review your classmates’ posts and comment as appropriate on at least two other posts per the Discussion Guidelines.
1. The cell consists of numerous organelles and structures surrounded by the plasma membrane (e.g., lysosomes, mitochondria, etc.).
Then include the following for each disorder:
2. Cells need to communicate with each other in order for organs and organ systems to develop and function. There are multiple mechanisms by which cells communicate with each other. Circulating hormones (endocrine system) allows communication over long distances between multiple cell types. Paracrine signaling offers local communication between cells. Finally, gap junctions allow communication between adjacent cells.
Then include the following for each disorder:
