PSY 230 Chapter Notes - Chapter 5&8: Breast Milk, Neuroglia, Growth Cone
Document Summary
Neuron nerve cell (axon & dendrites: billions of neurons, healthy neurons must communicate, metabolize, and repair themselves. Gill cells cells that provide support, nourishment and protection to neurons. Synaptic gap junction between the axon of one neuron and the dendrites of another, messages travel through here. Neurotransmitters chemical messengers that travel through the synaptic gap to send messages: physical structures. Cerebellum helps coordinate voluntary movement and balance. Thalamus sensory switchboard, chooses what to pay attention to. Limbic system emotions, drives, and rewards. Cerebral cortex control centers, made up of lobes split between two hemispheres that work together: frontal lobe. Adult weight 3 lbs (about the size of a medium cauli ower) Production: embryonic disc forms neural tube neurons formed inside. Migration: glial cells make ladders to move neurons throughout the body looking for certain proteins. Aggregation: neurons that are looking for distinct proteins gather. Differentiation: distinctions made between neurons specialization of function. Growth: continue to further develop: development by birth.
