1

What does the hypothalamus regulate?

1

Name outputs from the hypothalamus.

1

Name inputs to the hypothalamus

1

The preoptic area of the anterior hypothalamus contains structures that are associated with what functions?

1

The posterior hypothalamus contains structures that are associated with what functions?

1

The periventricular zone of the hypothalamus contains structures that are associated with what functions?

1

The medial zone of the hypothalamus contains structures that are associated with what functions?

1

1

On the following diagram of the hypothalamus, what does the green question mark show?

1

On the following diagram of the hypothalamus, what does the red question mark show?

1

On the following diagram of the hypothalamus, what does the blue question mark show?

1

On the following diagram of the hypothalamus, what does the purple question mark show?

1

What are the three main functions of the hypothalamus?

1

Exteroreceptors and Interoreceptors input to the hypothalamus via the ANS which monitor the internal and external body environments respectively.

1

Outputs of the hypothalamus to the ANS go via the brain stem and give rise to the SNS and PNS.

1

The hypothalamus is linked directly to both the anterior and posterior pituitary gland.

1

Neurohormones released from axonal projections from the hypothalamus to the posterior pituitary travel directly into the bloodstream and into the circulation.

1

Name two hypothalamic inputs that would monitor short-term behavioural aspects

1

Leptin is a hormone released from

1

Leptin acts on the hypothalamus to result in what effects?

1

The arcuate nucleus contains a high density of leptin receptors.

1

What is the purple structure seen on the coronal section of the hypothalamus?

1

What is the function of the paraventricular nucleus in response to signalling from the purple structure?

1

What is the function of the lateral hypothalamic area in response to signalling from the purple structure?

1

What three functions can hypothalamic thermoreceptors co-ordinate?

1

The anterior hypothalamus contains temperature-sensitive neurons that can change their firing rate depending upon if the temperature is hot/cold.

1

Pyrexia is a return to the normal temperature set-point in the hypothalamus.

1

What three reproductive functions (behavioural) does the hypothalamus have?
