Document Summary

Nucleus: information storage and transmission; ribosome subunit assembly; structural support. Golgi apparatus: protein, lipid, and carbohydrate processing. Endoplasmic reticulum: rough- protein synthesis and processing; smooth- lipid synthesis and processing. Actin filaments: cells shape, muscle contraction, cell adhesion (cytoskeleton) Membrane-forming lipids have a polar, hydrophilic region -in addition to the nonpolar, hydrophobic region found in all lipids. The charges and polar bonds in the head region interact with water molecules when a phospholipid is placed in solution. In contrast, the long hydrocarbon tails of a phospholipid are nonpolar and hydrophobic. The hydrophobic lipid tails of the phospholipid membrane do not permit hydrophilic ions to cross the membrane. Axon, dendrite, soma (cell body) presynaptic terminal, synapse. Parts of a neurons: a type of eukaryotic cell. Soma: cell body, the bulk of the actual cell, contains the nucleus. Neurites: branches, or processes that extend from the soma. There are two types of neurites: dendrites and axons.
