Document Summary

Topic 2: biology of the mind: structure, neuron. The cell body (soma): important because the cell body maintains the neuron. Dendrites are important because information enters the neuron through the dendrite. Axon: the nerve impulse will travel down the axon. In from the dendrite and down the axon. It has a blue covering (myelin: it insulates the axon, making the transfer though the axon faster). Axon terminal: that is the way the nerve impulse leaves the axon: overview. Into the cns through the sensory neurons, they take the info from the body and send it to the brain. Glial cells support: the unsung support workers of the interneuron"s. Janitorial support: basic functioning, direction of neural impulse: toward axon terminals. When a neuron is at rest and it has not been stimulated, there is a negative charge on the inside, positive on the outside (it is polarized).
