Brain Development

This is the process in which neural pathways used often are strengthened.

• Synaptic Pruning
• Myelination
• Limbic System
• Prefrontal Cortex

This is the process in which neural pathways not used often are eliminated.

• Synaptic Pruning
• Myelination
• Limbic System
• Prefrontal Cortex

This is the region of the brain responsible for critical thinking, decision making, and considering consequences.

• Limbic System
• Synapses
• Neurons
• Prefrontal Cortex

• It always is maturing.

Because messages cannot occur over synapses on their own, they require the help of ________.

• Myelin
• Neurotransmitters
• Axons
• Dendrites

This is the part of a neuron made up of threadlike fibers.

• Axons
• Dendrites
• Synapse
• Myelin

This is the part of a neuron made up of branchlike structures.

• Axons
• Dendrites
• Synapse
• Myelin

This is fatty substance (or sheath) that wraps around a neuron to strengthen it and make is more efficient.

• Axons
• Dendrites
• Synapse
• Myelin

This is is the space between cell bodies.

• Axons
• Dendrites
• Synapse
