Nervous Systems
The nervous system that calms us down after high levels of arousal
What is the Parasympathetic Nervous System
The part of the neuron that receives signals from other neurons
What are the dendrites
When tissue is damaged forever
What is a lesion
The structure that helps enable fear and aggression
The amygdala
The brain and spinal cord contain this type of neurons
What are interneurons
The function of the myelin sheath is to?
Insulates the axon and speeds up neural messages
A scan that is typically used to study sleep behaviors/seizures by using electrodes and shows brain activity
What is an EEG
The brain structure that is necessary for vital functions
What is the medulla
Two ways that genes can be expressed
These neurons send messages from the body to the brain and spinal cord
What are sensory neurons
When + and - ions are separated before action potential occurs
What is resting potential
A lobe (if damaged) that can cause a total change in someone's personality
Frontal lobe
The difference between fraternal and identical twins
Identical-have the same DNA/came from one egg
Fraternal-have different DNA/came from two different eggs
This system is responsible for our involuntary body responses
What is the autonomic nervous system
The structure of a neuron that shoots messages (neurotransmitters) to other neurons dendrites
What is the axon terminal
The part of the brain that gets damaged and can prevent you from physically speaking
Brocas area
The major difference between nature and nurture
Nature-genetic predisposition/inherited traits
Nurture-surrounding environment/learned experiences
What are three examples of what our body does in response to our sympathetic nervous system being activated?
Heartrate increases, breathing increases, digestion slows, pupils dilate, sweating increases
The autoimmune disease that is the result of the breakdown in myelin sheath
Multiple sclerosis
The key element used for PET scans to see brain activity
What is radioactive glucose
The gland that secretes our growth hormones
What is the pituitary gland
The study of how our environments cause our genes to activate
