Chapter 6 Flashcards
Neurons send electrical signals which cross the synapse by the flow of _______
Neurotransmitters
Thus ensures effective and speedy message transmission
- Myelin
What are the 3 phases of brain development?
- Cell production (Neurons are produced between 10& 26 wks post conception
- Cell migration (nerve cells travel from the inner neural tube outward to final location)
- Cell elaboration (synapses are formed, nerve cells are ‘pruned’
Axons like connections form during _______
Migration
This is a combination of an axon expanding and dendritic sprouting that provides the ingredients for forming synapses. It mostly occurs between birth and 24 months
- Synaptogenesis
Myelination occurs after cell _______
- Migration
This is a chemical that transmits electrical activity from one Neurons across the synapse to another Neuron
- Neurotransmitter
Noradrenaline, Dopamine, Serotonin, and Cholingeric are the 4 ____________ systems
- Neurotransmitter
The brain stem, midbrain, and cerebrum are the 3 _____ parts of the brain
- Major
The frontal lobe contains the Broca’s area. What is it responsible for?
- Speech formation
What is the difference between the left and right hemispheres of the cerebrum?
- Left = language performance, verbal memory, words and concepts
- Right = spatial and mathematical tasks
The temporal lobe contains the wornicke’s area, what is it responsible for?
- Language
Body sensations such as touch are controlled by the ______ lobe.
- Parietal
Visual association aka sight is controlled by what lobe?
- Occipital
The cerebellum controls what?
- Movement
