PHSI3012 06-1 Stress and Cardiovascular Disease

3 ways of ascertaining the degree of sympathetic activity: (select all that apply)

True or false: Sympathetic activity is often raised in CV disease.

True or false: Sympathetic activity is often lowered in CV disease.

The DMH is: [blank_start]_____[blank_end];[blank_start]_____[blank_end];[blank_start]_____[blank_end]

Inhibition of DMH [blank_start]__________[blank_end] the [blank_start]_____[blank_end] response to air-jet stress.

What is the origin of tonic sympathetic drive?

Release of [blank_start]__________[blank_end] from the anterior pituitary is controlled by [blank_start]__________[blank_end], released from neurons originating from the [blank_start]__________[blank_end] in [blank_start]__________[blank_end].

Lesions on the [blank_start]__________[blank_end] largely abolish the increases in BP and HR associated with [blank_start]__________[blank_end] fear, but have no effect on the increases in BP and HR associated with [blank_start]__________[blank_end] psychological stress.

Stimulating the DMH artificially will see a substantial [blank_start]__________[blank_end] in [blank_start]__________[blank_end] activity (along with HR and BP).

The DMH is crucial for mediating cardiovascular responses to [blank_start]__________[blank_end] stresses, whereas the PeriFornical area (PeF) is crucial for mediating cardiovascular responses to [blank_start]__________[blank_end] stresses.

Which of the following is involved in mediating CardioVascular response(s) to stress?

c-Fos is a gene (Immediate Early Gene – IEG) that produces Fos in response to stress stimulus. What is Fos? (“Produced in neurones that have been activated recently”)

Exercise and Stress both cause increases in HR and BP. Nonconditioned stress (e.g. airpuff) is mediated [more] by the [blank_start]__________[blank_end]; whereas exercise response is mediated [more] by the [blank_start]__________[blank_end].
