1

Define; Isometric tension recording

1

Would isometric tension recording occur, in vitro or in vivo?

1

Is this statement true?
Wire myography requires dissection skills and is better used for small vessels with an internal diameter of 100-400 micrometers.

1

What do changes in tension of a blood vessel indicate?

1

Is this statement true?
Nitric Oxide is a signalling molecule in the cardiovascular system

1

Pick from the list below, the disadvantages of the cardiovascular techniques studied;

1

What does a stretch in smooth muscle cause?

1

Is this statement true?
Shear stress has frictional force on the endothelium leading to vasoconstriction

1

What causes the impairment in the sheer stress mechanism to cause vasoconstriction?

Revision tool for those studying Therapeutics and investigation 1, as a second year biomed studying at St Georges, This quiz has a range of different topics, but mainly focuses on experimental techniques used in the biomedical sciences degree.
