SHS 485 EXAM 1 STUDY GUIDE
Myelin - Answer -White that covers and insulates axons. It speeds up the transmission
of the signal.
Dendrites - Answer -Receive input from another cell.
Axon - Answer -Transmits signal away from the cell body.
Axon Hillock - Answer -integrates multiple signals into one signal to transmit to the next
axon.
Synapse - Answer -information from one neuron flows to another neuron.
Grey Matter - Answer -Made up of cell bodies and dendrites. Outside of the cortex and
inside of spinal cord. Selective connections and reciprocal
White Matter - Answer -Made up of myelinated axons. Outside of spinal cord. Connect
areas of the Cortex.
Three Pathways - Answer -Descending, Ascending, Cortico-cortico
Fasciculi - Answer -Long pathway
Homologous connections - Answer -Between hemispheres. Ex: two hands working
together
Cortex - Answer -Grey matter, Sulci, Gyri, Lobes
Sulci - Answer -Valley
Gyri - Answer -Bumps
Subcortex - Answer -White matter, Ventricles, Subcortical Nuclei
Subcortical Nuclei - Answer -Brain matter you cannot see from the outside. Ex: Basal
Ganglia, Claustrum, Amygdala
Primary Cortex - Answer -Auditory (Heschel's Gyrus), Motor (Pre-Central Gyrus),
Sensory (Post-Central Gyrus), Visual (Calcarine sulcus)
Non-Primary Cortex - Answer -Everything else; more than one function
Lobes - Answer -Frontal, Parietal, Occipital, Temporal, Insular
