Document Summary
Nervous system: has 3 main functions a. i. Sending output or response (i. e. moving muscles, telling lungs to breathe faster, digestion, etc. : does its functions with very quick electrical activities b. i. In thousandths of a second: made of billions of neurons that are constantly communicating with each other, neurons can communicate with each other and with other cells in the body through electrical and chemical signals. Functional unit: neuron: the way they communicate is by electrical activities, as this electrical activity is processed from one neuron to another, there"s a shift: electrical to chemical to electrical to chemical communication, etc. But neurons have the major function of the nervous system: accessory cells are helper cells, neurons are excitable cells, meaning they exhibit/process electrical activities. Em: neurons magnified 6000x, has all the organelles we"ve learned about (typical cell, shape is different from regular cell c. i.
