Please feel free to label as many structures as you can. The lack of color in this image makes it much closer to what an actual human cell looks like – off-white, often grayish, for example (looking through a microscope). Also, I like the artistic quality of the sketch. Hope it helps those of youContinue reading “Basic Human Cell: Labeling Exercise”

Levels of Muscle Organization
Skeletal muscle’s function is to contract and cause movement. This figure represents the different levels of muscle organization. This 3-D anatomy is difficult to remember and keep straight in your brain. It also may be rather difficult to visualize this figure in your mind. You will be very glad if you can, though, as itContinue reading “Levels of Muscle Organization”
Types of Chemical Bonds
What is this?
I don’t normally do this, but I thought it would be interesting. This is a work in progress for my Lecture Notes Series, where I discuss important Anatomy & Physiology topics. What topic do you think I will be discussing? I will be impressed by whomever gets it right!
Na-K Pump: Active Transport
Active Transport is active (as opposed to passive) because it uses chemical energy released by breaking off one inorganic phosphate from ATP. In the case of the Na-K Pump, that energy is used to change the shape of the membrane transport protein, thus dumping out 3 Na+ ions. This movement of sodium out of theContinue reading “Na-K Pump: Active Transport”
