Description

January 16th -

Neurons - Conduct action potentials - Process information - Send signals - Process input, command output - Sensing environmental changes - Communicate changes with other neurons

-

Glia -

Myelinate axons (insulate neurons) Support neurons Clear dead neurons and pathogens

-

Structure is related to function (esp. dendritic structure) - Stress causes dendritic growth in the amygdala - Dendritic shrinking in the hippocampus/prefrontal cortex

-

Neuron parts - Dendrites: collect input - Soma (cell body): contains organelles and nucleus - Axon: transmits signal to the terminal - Terminal: release signal to the next neuron

-

Neuron types - Sensory: bring information to central nervous system - Interneurons: associate sensor and motor activity in the central nervous system - Motor: send signals from brain and spinal cord to muscles

-

Point of communication from one neuron to another is the synapse
