PSY-2012 Lecture Notes - Lecture 5: Falsifiability, Brain Mapping, Ganglion Cell
Document Summary
For the following, be able to recall the name and functions as well as appropriately label them on a diagram of a neuron: (pages 85-87) Dendrite-branch like extensions that receive information from other neurons. Axon- long tail like extensions are very thin near the cell body, they send messages to other neurons. Myelin sheath- fatty coat contains gaps all the way along the axon called nodes that help the neuron conduct electricity more efficiently. Axon terminal- knoblike structure where the synaptic vesicles travel to in order to release neurotransmitters. Synapse- tiny fluid filled space between neurons through which neurotransmitters travel. Synaptic vesicle- tiny spheres that travel the length of the axon to release neurotransmitters, these spheres are similar to capsules filled with meds. When we swallow the capsule the exterior dissolves releasing the medication. Oligodendrocyte- promotes new connections among nerve cells and releases chemicals to aid in healing: produces an insulating wrapper around axons (myelin sheath)
