NEUROSC 10 Lecture Notes - Lecture 2: Camillo Golgi, Wilhelm His Sr., Gap Junction
Document Summary
Has a similar structure to any general cell type in the body within the cell body. Uniquely features dendrite and axon members; axon is generated as a dendritic growth - one of many neurites - which develops a growth cone complete with filopodia and lamellopodia, as studied by. Ramon y cajal, and grows faster and longer than other, similar growths, ultimately becoming the cell"s axon, while the other neurites become dendrites instead. Growth and development of axons may be related to memory enforcement. The cleft between the axon of one cell and the dendrite of another is the synaptic cleft. Neurotransmitters kept in reserve on one side of the cleft may be released as part of an electrochemical reaction during neuronal activity; they are carried in vesicles across the cleft to the other cell. The polarization of the cell"s interior relative to extracellular fluid is key in determining cell behavior during neuronal firing.
