This semester the subject that i liked is celular phisiology, although I have study this subject in another career, I've always liked the topic about this.
The principal contents that has been studied are homeostasis (cellular maintenance with his envornment), water movement through the plasmatic membrane (and others compartments), biophysics (membrane potential, action potential, among others) and celullar comunication (synapses, hormones, among others).
The complexity about them is what attracts me to this subject, and like mathematics is imnvolved in practically everything, I would like keep on learning about this subject over the years.
