Teenage Brain

Define limbic system

• a brain system that plays a central role in emotional response

• thread-like fibers

• a signal that is both electrical and chemical

• to cause growth/development

define neuro transmitter

• protect

• fatty insulating layer

• myelin

• chemical messengers that help carry the signals in the brain

define synapse

• a brain area important for thinking ahead and sizing up risk and reward

• the small space between axons and dendrites where neurons exchange information

• a process in which axons become wrapped up in fatty myelin sheath

• a signal that is both electrical and chemical

What is the function of the prefrontal cortex?

• It regulates the body's temperature

• It is involved in decision making and social behavior

• It controls the heart rate

• It processes visual information

Define axon

• A protective layer around the brain

• A chemical that transmits signals across a synapse

• A long fiber that transmits signals away from the neuron cell body

• A part of the neuron that receives signals

Define dendrite

• A chemical that transmits signals across a synapse

• A part of the neuron that receives signals from other neurons

• A long fiber that transmits signals away from the neuron cell body

• A protective layer around the brain

Define myelin sheath

• A chemical that transmits signals across a synapse

• A part of the neuron that receives signals from other neurons

• A fatty layer that insulates axons and speeds up signal transmission

• A protective layer around the brain

cells that are specialized to transmit messages

• Autonomic
• Neuroglia
• Neurons
• Somatic

What is a synapse primarily described as in the context of neuroscience?

• A type of neurotransmitter

• A connection between two neurons

• A molecular machine

• A specific type of brain cell

define synaptic pruning

• branch-like structures

• specialized cells in the brain

• cutting back the number of synapses

• space between axons and dendrites
