Gamification Simultaneous Action Selection Mechanic

Dr. Mays uses the Simultaneous Action Selection mechanic to structure his lesson. He creates two decks of cards—one with names of different cellular components (e.g., ribosomes, endoplasmic reticulum) and another with a wide assortment of cellular functions and processes. He seats students in groups of five or six and explains the rules. During each turn, one student is going to pick a card from the component deck and read it out loud. Then the other students select a card from their hand (...

 Relative Sizes of Structures in the Brain

Linear measure- ments and dimensions generally are given in microns or micrometers (µm) (1 µm equals one- millionth of a meter) or nanometers (nm) (1 nm or millimicron equals one-billionth of a meter). About 240,000 µm equal one inch. As a reference, the following are the dimen- sions of some non-neural structures: human ovum, 100 µm; cross-section of a skeletal muscle fiber, 10-100 µm; erythrocytes, 8–10 µm; bacteria, 0.1–8 µm; and viruses, 0.15–0.5 µm. Cell bodies of neurons...
