|
Gregory Mendel
|
Father of genetics. Used pea plants to learn about dominant traits and recessive traits.
|
|
|
Chromosome
|
Strand of hereditary material. 46 in cells in your body, 23 pairs.
|
|
|
Gene
|
Units of a chromosome. Directions for both psychological and physical characteristics.
|
|
|
DNA
|
Very complex molecule shaped like a twisted ladder. Can make copies of itself.
|
|
|
Neuron
|
Cell specialized to receive and transmit info to other cells in the body.
|
|
|
Soma
|
Part of a neuron containing the nucleus, which includes the chromosome. AKA cell body.
|
|
|
Dendrites
|
Collect info. and deliver to soma.
|
|
|
axon
|
carries info away from the soma
|
|
|
myelin
|
insulation,lipid,fatty, around the axon.
Multiple Sclerosis- condition in which the myelin disintegrates. |
|
|
synaptic knobs
|
knob-like structures. store chemicals
|
|
|
synapse
|
microscopic spaces between neurons. When knobs release chemicals, they cross the synapse.
|
|
|
Psychoneuroimmunology
|
Studies relationship between mental states an the immune system.
|
|
|
Behavioral medicine
|
Studies link between behavior and disease.
|
|

|
|
|
type b personality
|
laid back, easygoing, social
|
|
|
Locus of control
|
introversion or extroversion.
|
|
|
Inhibition
|
Cell is less likely to communicate.
Dendrited recieve chemicals, deliver to soma, soma gets inhibited, now less likely to communicate. |
|
|
excitation
|
Dendrites recieve excitatory chemicals, deliver info to soma, soma/cell becomes excited. If very excited it leads to Action Potential.
|
|
|
The action potential
|
If cell very excited. electricity generated, travels length of axon causing synaptic knob to release chemicals into synapse.
