Document Summary
Explore the ways that cells aggregate with each other to form tissues. Compare and contrast the four types of animal tissue. Explore the functions of cells in their social context; Mod 2 energy systems and cells page 1. Screen clipping taken: 4/11/2017 11:51 pm e. g. simple squamous. Mod 2 energy systems and cells page 2 connective. Smooth in every hollow organ except heart, fibres run criss cross, spindle shape, involuntary. Mod 2 energy systems and cells page 3 v. Explain how cells communicate and regulate cell growth in a healthy state (e. g. differentiation of stem cells) and what can go wrong to result in a pathophysiological state (e. g. cancer) Steroid hormones - hydrophobic, can go through cell membrane, like fatty lipid cells, can interact with intercellular receptor. Mod 2 energy systems and cells page 4. Protein hormones - hydrophillic, interact with receptor on plasma membrane. Can turn on enzymes in cytosol and send messages to dna to activate protein.
