Electric Connection
The chemicals that travel between neurons in synapses
neurotransmitters
This is the brain lobe that processes visual information
occipital lobe
The information encoded for a particular trait
Genotype
The long tail extending from th cell body of a neuron
axon
The 4 types of Genetic Disorders
X-linked, Single Gene, Recessive, and Chromosome
The neuron before the synapse
presynaptic neuron
This lobe is responsible for higher cognitive functions
Frontal lobe
Traits that are physically expressed
Phenotype
the sheath that covers a neuron's axon to help the action potential move faster
Myelin sheath
The study of how your behaviors and the environment affect your genetics
epigenetics
This is the gap between the axon terminal of one neuron and the dendrites of another
synaptic cleft
This is the section of tissue that connects the left an right hemispheres, allowing them to communicate
Corpus Callosum
If a pink flower was the offspring of a parent with red flowers and a parent with white flowers, this is an example of...
incomplete dominance
The two ions that cross the cell wall to maintain electrical potential in a neuron
Sodium and Potassium (Na+ and K+)
A change that occurs in the gene structure
mutation
hypothesized number of synapses in the brain
100 trillion
This part of the brain plays a role in memory formation, and the piece of the brain that HM was mising
Hippocampus
Heterochromia and AB blood types are examples of what?
Codominance
The charge that moves down an axon and triggers the release of neurotransmitters
action potential
something that results from many genes
polygenic
The receiving part of a postsynaptic neuron
dendrites
This is the part of the brain that plays a key role in processing emotions (also just fun to say)
Amygdala
The likelihood that two related people will be similar to each other is called...
Concordance rate
~86 billion
many traits resulting from a single gene
pleiotropic effects
