Frage 13
Frage
What are the three main functions of the hypothalamus?
Frage 14
Frage
Exteroreceptors and Interoreceptors input to the hypothalamus via the ANS which monitor the internal and external body environments respectively.
Frage 15
Frage
Outputs of the hypothalamus to the ANS go via the brain stem and give rise to the SNS and PNS.
Frage 16
Frage
The hypothalamus is linked directly to both the anterior and posterior pituitary gland.
Frage 17
Frage
Neurohormones released from axonal projections from the hypothalamus to the posterior pituitary travel directly into the bloodstream and into the circulation.
Frage 18
Frage
Name two hypothalamic inputs that would monitor short-term behavioural aspects
Antworten
-
Glucose receptors - detect glucose levels
-
Mechanoreceptors - detect how full you are
-
Metaboreceptors - detect how full you are by the accumulation of metabolites at a site
-
Baroreceptors - detect how full you are by pressure on the walls
