Function of limbic system+ hypothalamus Flashcards

Describe function of limbic system in olfaction
for perception and discrimnation of odors
FPAEN
___________________-
-Frontal and Orbitofrontal corex for perception and discerimnation of odors
-Piriform for perception and discrimnation
-Amygdala for odor emotions
-Entorhinal for odor memory
Limbic system odor is closely related to
Emotion
Memory
Sex
Limbic system odor is closely related to
Limbic system odor is closely related to
Emotion
Memory
Sex
Limbic system control autonmoic fucntions as part of
Emotions
Limbic system control feeding and appetite so lesio leads to ?
Hyperphagia
Omniophagia
Limbic system Control ,,,,,and ,,,,,, behavior
Maternal
Sexual emotion expressed
____________
Sexual behavior affected by?
Prefrontal cortex
Social factors
Psychic factior
Limbic system and memory
Encoding and consolidation of STM in Hippocampus into LTM

Feeling associated with Autonomic and endorincal changes

mention specific parts of limbic system and the emotions generated from
Amydala + Left hypothalamus = Rage aggression
______________
Amygdala + Preventricular are =Fear

Limbic system controls Motivation show!
Through
Reward approach via
Latreral and ventromedial hypothalamus
thalamus
amygdala
via dopamine
causing pleasure and satisfaction
_________________________
Punishment aversion avoidance :
PVN PAGA
amygdala
by Ach casuing
displeasure and fear
Cocain gives pleasure by?
++ dopaminergic neruins in reward system
General and main function of hypothalamus ?
Control intenal Homeostasis
Hypothalamus has contorl on endocrinal system show
Nervous : nerves going to posterior pituitary giving vasopressin and oxytocin and
Control Adrenal Medulla for catecholamines
___________________
Hormonal : via contorl of anterio pituirary the mystro controlloing most of body endocrine glands
Control of autonimic functions by hypothalaus show !
Anterior hypotahalmus of Non REM for parasymp
Posteriolateral hypothalamus of arousal for symp
How does hypothalamus control feeding
by Feeding and staiety centers
__________________
Feeding in lateral with intrinsic ac while staiety in VM hypotahalmus without intirnsic act
________________________
Feeding inhibited by staiety
Staiet stimulated by glucose in pres of insulin insulin depndent glucostat
______________________
Lesion to feeding casuing anorexia while staity causing hyperphagia
________________
Hypothalamus regulate H2O balance and ECF how?
Thirst and ADH
_______________-
Thirst center in lateral hypothalamus controlling water intake
_________________
Vaspressin in SupraOptic Nucleus controlling water loss
Hypothalamus regulate temp how?
Heat gain and loss centers
Heat gain in posterior hypothalamus csauing VC and shivering
__________________
Heat loss in anterior hypothala,us casuing
VD and Sweating
Hypothalamus controls sleep how?
Anterior hypothalamus for NREM
Posteiro hypothala,us for arousal
Orexin from hypotahalmus regulate switching between sleep and arousal
Hypothalamus control Circadian rhythm HOW?
Through SupraChiasmatic Nucleus the internal biological Clock
___________________=
Periodic dirunal Controlling regulation physiological processes as pressure hormones,HR according to ligh/dark cycle
Hyothala,us plays role in motivation and learining
also
Emotins and sexual drive how ?
The most anterior
The most posterior
hypothalamus casues Sexual drive
loss of sexual desire occurs if ?
Lesion to anterior hypothalamus occurs
Describe papetz circuit
From hippocampus to fronix to mamillary bodies to anterior thalamus to cingulate to hippocampus rrrrrrrrr

Reverbrating circuits
Long after discharge
Play a major role in emotions
“يا أهل الكتاب قد جاءكم رسولنا يبين لكم كثيرا مما كنتم تخفون من الكتاب ويعفو عن كثير قد جاءكم من الله نور وكتاب مبين يهدي به الله من اتبع رضوانه سبل السلام ويخرجهم من الظلمات إلي النور بإذنه ويهديهم إلي صراط مستقيم”

Olfaction explain
Hypothalalmus function
H2E2A2T SLEEP
2H=Homeostasis + H2O ECF
2E = Emotional Endorinal
2A = Appetite Autonomic
T=Temperature
Sleep
