1. Strongest bond- covalent bond (share electrons)
2. Proteins are made out of amino acids
a. Function as enzymes, structure roles, movement
b. Levels of structure
3. Plasma membranes- communication w other cells, structure support, isolate cell from
surroundings
4. Golgi- packing/routing
5. Simple diffusion factors: mass/size, membrane surface area, permeability, temperature,
concentration difference
6. Water moves towards high solute concentration
7. Endocytosis and exocytosis are active transport via vesicles
a. Transcytosis is both together
8. Four functions of skin
9. Keratinocytes make up skin
10. Spongy bone is found in epiphysis
11. Osteoclasts (break down), blasts (building)
12. Acetylcholine is released in response to action potential arriving
13. Sodium channels on motor end plate- ligand gated
14. Atp/myosin binding- release
15. ADP/Pi = power stroke
16. During muscle fiber relaxation, calcium channels in the SR close because the resting
membrane potential is restored
17. During muscle fiber relaxation calcium is pumped back into the SR
18. Threshold for neurons is -55 mV
a. EPSP/IPSP, summation
19. Refractory period- prevents flow of AP towards cell body
20. Terminal bouton opening of calcium
21. Cerebellum- planning and coordination
a. Basic functions
22. White matter- myelinated axons
23. somatic/visceral motor/sensory
24. Mechanoreceptors
25. Cholinergic synapses: acetylcholine
26. Norepinephrine effects target cells
27. Blocking parasympathetic: muscarinic
28. Intense physical activity, parasympathetic down/sympathetic up
29. Left is thicker in heart because it goes to systemic
30. Semilunar open w high ventricle pressure
31. Cardiac vs muscle: intercalated discs
32. SA nodes are fasted pacemakers
33. Calcium channels open during plateau phase
34. Veins have more elasticity than arteries
35. Transcytosis needs ATP
