3 ways of ascertaining the degree of sympathetic activity: (select all that apply)
Noradrenaline levels
Noradrenaline spillover
Direct nerve recording
Yawning in front of them
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: Dorso- Direct Dorsal( Dorso-, Direct, Dorsal );Medial Medullary Medulla( Medial, Medullary, Medulla );Hypothalamus Hippocampus Hemisphere( Hypothalamus, Hippocampus, Hemisphere )
Inhibition of DMH blocks increases( blocks, increases ) the CV VC( CV, VC ) response to air-jet stress.
What is the origin of tonic sympathetic drive?
Rostral VentroLateral Medulla (RVLM)
RetroTrapezoidal Nucleus (RTN)
Read The Fucking Manual (RTFM)
Release of ❌ from the anterior pituitary is controlled by ❌, released from neurons originating from the ❌ in ❌.
Lesions on the ❌ largely abolish the increases in BP and HR associated with ❌ fear, but have no effect on the increases in BP and HR associated with ❌ psychological stress.
Stimulating the DMH artificially will see a substantial Increase Decrease( Increase, Decrease ) in Sympathetic Parasympathetic( Sympathetic, Parasympathetic ) activity (along with HR and BP).
The DMH is crucial for mediating cardiovascular responses to ❌ stresses, whereas the PeriFornical area (PeF) is crucial for mediating cardiovascular responses to ❌ stresses.
Which of the following is involved in mediating CardioVascular response(s) to stress?
DorsoMedial Hypothalamus (DMH)
PeriFornical area (PeF)
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”)
A Neurokine
A Protein
A Hormone
A Cytokine
An Enzyme
Exercise and Stress both cause increases in HR and BP. Nonconditioned stress (e.g. airpuff) is mediated [more] by the ❌; whereas exercise response is mediated [more] by the ❌.
