Document Summary
Psych 261 - 1. 1: cells of the nervous system. Nervous system consists of two kinds of cells: neurons and glia. Neurons: receive info. and transmit to other cells. Santiago ram n y cajal: pioneer of neuroscience. His research = showed nerve cells remain separate instead of merging into one another. Surface of a cell: membrane, a structure that separates the inside of the cell from the outside environment. Protein channels in membrane permit a controlled flow of water, oxygen, sodium, potassium, calcium, chloride, other imp. chemicals. Mitochondrion (plural: mitochondria): performs metabolic activities, provides energy that cell uses for all activities, mitochondria requires fuel and oxygen. Ribosomes: sites where cell synthesizes new protein molecules. Proteins provide building materials for the cell and facilitate chemical reactions some float freely in the cell, but others attached to endoplasmic reticulum (network of thin tubes that transport newly synthesized proteins)
