NSCI 175 - Unit 2
Neurons - Answer-sense changes in environment, communicate to other neurons, command body
actions, most in charge of brain info processing, choc chips
Glia/Glial cells - Answer-insulate, support, nourish the neurons around them, other part of the cookie,
"glue"
histology - Answer-microscopic study of the structure of tissues
Nissl stain - Answer-a neural stain that stains some selective cells in brain tissue, but not all
cytoarchitecture - Answer-arrangement of neurons in diff parts of the brain
Golgi stain - Answer-a neural stain that allows some neurons to be darkened by being put in a silver
chromate soln
Cell body/soma (somata=plural)/perikaryon - Answer-the large part of the neuron in the middle that
has the nucleus
neurites - Answer-the thin tubes that come out of the soma
, axons - Answer-type of neurite (longer one)
dendrites - Answer-type of neurite (lots of them, shorter ones), like antennae to receive incoming
signals, or input
neuron doctrine - Answer-Cajal's idea that neurites communicate by contact, not continuity
cytosol - Answer-watery fluid inside the cell, a salty, potassium-rich soln
organelles - Answer-membrane-enclosed structures inside the soma
cytoplasm - Answer-everything in cell membrane except nucleus
nucleus - Answer-Latin "nut," contained within a double membrane (nuclear envelope) that has pores
chromosomes - Answer-inside nucleus, contain genetic info (DNA)
deoxyribonucleic acid (DNA) - Answer-genetic material in the chromosomes
genes - Answer-segments of DNA that are used to assemble the cell, make it distinct from another cell
type
gene expression - Answer-reading of the DNA
proteins - Answer-final product of gene expression
