Neurons |
Cells which receive information from and transmit information to other cells |
|
Glia |
Cells that do not transfer info over long distances, but exchange chemicals with adjacent neurons; sometimes act to oscillate cell activity. |
|
Santiago Ramon y Cajal (1852-1943) |
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. |
|
Membrane |
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 |
|
Nucleus |
Structure that contains the chromosomes |
|
Mitochondrion |
Structure that performs metabolic activities. Provides energy for the cell. They differ genetically and mutations in these genes can cause autisim |
|
Ribosomes |
Sites at which the cells synthesize new proteins |
|
Endoplasmic reticulum |
Network of thin tubes that transport newly synthesized proteins to other locations |
|
Motor Neuron |
Receives excitation through its dendrites and conducts messages along its axon to a muscle- has its soma in the spinal cord. |
|
Sensory neuron |
Specialized to detect a particular type of simulation (light, taste, touch) |
|
Dendrites |
Receives info from other neuron |
|
Dendritic spines |
Further the branch out and increase the surface area of the dendrite. The more surface area the more info can be recieved. |
