MSH & Beta-endorphin
|
|
|

|
|
What are the two hormones the hypothalamus makes?
|
Vasopressin (ADH) & Oxytocin
(transported and released by the posterior pituitary) |
|
|
What nucleus cells produce vasopressin?
|
Supra Optic Nucleus - axons project down through the infundibulum into the posterior pituitary
("I'm up to my eyeballs in pee") |
|
|
What nucleus cells produce Oxytocin?
|
Paraventricular nucleus - axons project down through the infundibulum into the posterior pituitary
|
|
|
What hormones of the hypothalamus are neurotransmitters?
|
Vasopressin and Oxytocin
(when these neurons fire, they produce exocytosis of these neurotransmitters but they are dumped into the blood {which makes them hormones}) |
|
|
What are five different disorders associated with limbic function?
|
1. Frontal Lobes Dysfunction
2. Temporal Lobe Dysfunction 3. Depression 4. Schizophrenia 5. Amnesia |
|
|
What is a lobotomy used for and what is affected?
|
Calms a person down
Temporal Lobe |
|
|
What is caused by degeneration of the frontal lobes and prefrontal cortex and results in inappropriate behavior like laughing at the wrong moment or vulgar and clownish behavior?
|
Tertiary Syphilis - causes clownishness
Affects the temporal lobe |
|
|
What disorder makes someone fixate on a stimulus and become hyper oral?
|
Kluver-Bucy Syndrome
Temporal Lobe Dysfunction § This is like what you see in a little kid -- they investigate by putting things in their mouth § If you gave someone with this syndrome a lit match, they will watch the match then stick it in their mouth. |
|
|
What is the result of a drop of 5-HT (serotonin) from Raphe?
|

|
|
What disorder causes an individual to stop existing in the physical world and only exist in a world your mind creates?
|
Schizophrenia
If you get further and further into the reality of your mind, you get into the catatonic state. |

|
Anterograde Amnesia - can't remember anything from this point forward
|
|
|
What type of amnesia do alzheimer's patients experience?
|
Anterograde Amnesia - can't remember anything from this point forward
|
|
|
What type of amnesia occurs when past memories are forgotten, but they can remember stuff from this point forward?
|
Retrograde Amnesia
most common amnesia of soap operas |
|
|

False They are intertwined
|
|
|
What concept is illustrated by:
Fear of pregnancy delaying menses Fear of impotence leads to impotence Depression can alter feeding behavior (some antidepressants induce weight gain) |
Emotion altering endocrine and hypothalamic function
|
|
|
What concept is illustrated by:
PMS Menopause - mood swings Midlife crisis - buying a sports car Hypothyroid depression - people with hypothyroidism typically have a depressed attitude |
Hypothalamus and endocrine systems can alter emotions
|
|
|
What concept is illustrated by:
Worrying produces sleep loss Depression producing somnolence/tiredness Worry decreasing ability to focus (distraction) |

|
|
|
What limbic structure has emotional control, as demonstrated by cats mounting other cats and not caring about what you are eating when this area is damaged?
|
Amygdala
|
|
|
What part of the limbic system has the association cortex go there to form memories?
|
Hyppocampus
|
|
|
*Which part of the association cortex deals with emotions?
|
Prefrontal Cortex
|
|
|
What are the components of the cortical limbic system?
|
Prefrontal Cortex
Temporal Cortex Parietal Cortex Cingulate Gyrus |
|
|
What allows us to bring together different sensory things and know they are coming from the same place?
|
Association Cortex
® A wet cat walks into your room at night and the association cortex allows you to recognize it, pick it up and smell it, feel it, etc. ® All of these things are coming in on different pathways and you're bringing them all together with the association cortex. |
|
|
What is the primary difference between the cortical and subcortical regions?
