14Exteroreceptors and Interoreceptors input to the hypothalamus via the ANS which monitor the internal and external body environments respectively.
- AVerdadero
- BFalso
15Outputs of the hypothalamus to the ANS go via the brain stem and give rise to the SNS and PNS.
- AVerdadero
- BFalso
16The hypothalamus is linked directly to both the anterior and posterior pituitary gland.
- AVerdadero
- BFalso
17Neurohormones released from axonal projections from the hypothalamus to the posterior pituitary travel directly into the bloodstream and into the circulation.
- AVerdadero
- BFalso
18Name two hypothalamic inputs that would monitor short-term behavioural aspects
- AGlucose receptors - detect glucose levels
- BMechanoreceptors - detect how full you are
- CMetaboreceptors - detect how full you are by the accumulation of metabolites at a site
- DBaroreceptors - detect how full you are by pressure on the walls
19Leptin is a hormone released from
- AAdipose tissue
- BThe hypothalamus
- CThe liver
- DConnective tissue
20Leptin acts on the hypothalamus to result in what effects?
- AIncreased metabolic rate (via pituitary and ANS)
- BDecreased feeding behaviour (limbic system)
- CDecreased metabolic rate (via pituitary and ANS)
- DIncreased feeding behaviour (limbic system)
21The arcuate nucleus contains a high density of leptin receptors.
- AVerdadero
- BFalso
22What is the purple structure seen on the coronal section of the hypothalamus?
- AArcuate nucleus
- BSuprachiasmatic nucleus
- CParaventricular nucleus
- DMammillary body
23What is the function of the paraventricular nucleus in response to signalling from the purple structure?
- ATells you when you've had enough to eat
- BTells you to when to eat
24What is the function of the lateral hypothalamic area in response to signalling from the purple structure?
- ATells you when you've had enough to eat
- BTells you to when to eat
25What three functions can hypothalamic thermoreceptors co-ordinate?
- AAutonomic - vasodilat/cont
- BBehavioural - shivering/sweating/panting
- CEndocrine - increase/decrease metabolism
- DAutonomic - sweating/shivering
- EEndocrine - vasodilat/cont
26The anterior hypothalamus contains temperature-sensitive neurons that can change their firing rate depending upon if the temperature is hot/cold.
- AVerdadero
- BFalso
27Pyrexia is a return to the normal temperature set-point in the hypothalamus.
- AVerdadero
- BFalso
28What three reproductive functions (behavioural) does the hypothalamus have?
