Course description
For designing machines and software for human use, it is important to know how human feel and use them. The elaborate mechanisms of the sensors and motile machineries that various living organisms have accumulated during evolution are full of clues for designing novel things. In this class, you will learn the basics of the human senses including vision, mechanical sense, and chemical sense along with the mechanisms how vertebrates and invertebrates perceive information for the environment. You will study a broad range of motile machineries from macroscopic system such as muscles to molecular system of cell and intracellular motility.
Purpose of class
The aim of this class is to understand the sensory and motile mechanisms in various organisms, to comprehend the elaborate survival tactics, and to obtain clues to manufacturing.
Goals and objectives
  1. I can explain the basic mechanisms for human sensation.
  2. I can explain the basic structure and mechanism for muscle, a motile machinery in living organisms
  3. I can explain some sensors and motile machinery in various living organisms.
