|
One dimensional model |
works in medicine sometimes, but there aren't many disorders where there is only one cause, except for down syndrome. |
|
|
multidimensional interactive model |
-Biological influences -psychological influences(cognitive, emotional and behavioral) -social influences -developmental influences Psychological disorders are a result of multiple interacting casual factors. |
|
|
Biological Influences |
-Genetics (non-defective gene and defective gene) -Major mental disorders cannot be linked to a single gene. -we inherit a PREDISPOSITION (if depression runs strongly in your family.) |
|
|
Diathesis-stress model |
-Diathesis is another name for predisposition -even if you have a certain amount of genes, the environment plays a major role. |
|
|
gene environment correlation model |
-focuses on active seeking out, driven by your genetics. |
|
|
Epigenetics |
-environment influences gene expression. -may override genetic vulnerability (diathesis) |
|
|
Neuroscience perspective |
studies the nervous system |
|
|
two main areas of the nervous system |
-Central nervous system -Peripheral nervous system |
|
|
Central nervous system |
processes and reacts to information received from the sense organs (brain and spinal cord) |
|
|
Peripheral nervous system |
works together with the brain to regulate bodily functions. |
|
|
Two parts to the Peripheral nervous system |
-Somatic system -Automic system |
|
|
somatic system |
controls muscles and movement as well as conscious movement. |
|
|
autonomic system |
regulates cardiovascular and endocrine systems as well as digestion and body temperature (heart beat, breathing,etc) |
|
|
The Autonomic system is divided in two parts |
-sympathetic branch -parasympathetic brance |
|
|
sympathetic branch |
mobilizes the body part that gears you up when you're scared or feel threatened. |
|
|
parasympathetic branch |
calms the body, allows your body to repair itself. |
|
|
what are systems made up of |
neurons
|
|
|
neurons |
nerve cells responsible for transmitting information throughout the nervous system.
|
|
|
neurons contain a... |
central cell body and two branches coming from it (dendrites and axons) |
|
|
dendrites |
received incoming signals from other neurons. If you get enough signals it will go through the threshold, if you don't have enough stimulation, it won't. |
|
|
axons |
there are axons in your legs, a lot of them in the brain, they all vary in length. |
|
|
Neurotransmitters |
chemicals that are secreted at the stored in vesicles. (drugs that treat psychological problems either increase or decrease the effects of various neurotransmitters. |
