Chapter 1: Nerve Cells And Nerve Impulses

Front 1

Neurons

Back 1

Cells which receive information from and transmit information to other cells

Front 2

Glia

Back 2

Cells that do not transfer info over long distances, but exchange chemicals with adjacent neurons; sometimes act to oscillate cell activity.

Front 3

Santiago Ramon y Cajal (1852-1943)

Back 3

One of the two main founders of neuroscience. He was the first to demonstrate that individual cells compromising the nervous system remain separate and do not merge. He also discovered the synapse.

Front 4

Membrane

Back 4

Structure that separates the inside of the cell from the outside environment; also caused plasma membrane.

Most chemicals cannot get through but certain proteins get through to help balance functions

Front 5

Nucleus

Back 5

Structure that contains the chromosomes

Front 6

Mitochondrion

Back 6

Structure that performs metabolic activities. Provides energy for the cell. They differ genetically and mutations in these genes can cause autisim

Front 7

Ribosomes

Back 7

Sites at which the cells synthesize new proteins

Front 8

Endoplasmic reticulum

Back 8

Network of thin tubes that transport newly synthesized proteins to other locations

Front 9

Motor Neuron

Back 9

Receives excitation through its dendrites and conducts messages along its axon to a muscle- has its soma in the spinal cord.

Front 10

Sensory neuron

Back 10

Specialized to detect a particular type of simulation (light, taste, touch)

Front 11

Dendrites

Back 11

Receives info from other neuron

Front 12

Dendritic spines

Back 12

Further the branch out and increase the surface area of the dendrite. The more surface area the more info can be recieved.
