Correct Answer-A
Meissner's corpuscles are dendrites encapsulated in connective tissue and respond to
changes in texture and slow vibrations. Merkel cells are expanded dendritic endings, and
they respond to sustained pressure and touch. Ruffini corpuscles are enlarged dendritic
endings with elongated capsules, and they respond to sustained pressure. Pacinian
corpuscles consist of unmyelinated dendritic endings of a sensory nerve fiber, 2 m In
diameter, encapsulated by concentric lamellae of connective tissue that give the organ the
appearance of a cocktail onion. Theses receptors respond to deep pressure and fast
vibration.

Simple diffusion is not carrier mediated
transport hence do not follow saturation
kinetics.

◦ Facilitated diffusion, primary active transport,
and secondary active transport all involve
integral membrane proteins and are called
carrier-mediated transport.
◦ All carrier-mediated transport system follow
saturation kinetics
◦ The figure shows that as the concentration
of the diffusing substance increases, the rate
of simple diffusion continues to increase
proportionately, but in the case of facilitated
diffusion, the rate of diffusion cannot rise
greater than the transport maximum (Tm).
Tm is analogous to maximum velocity
(Vmax) level in enzyme kinetics

Correct Answer -B

End diastolic volume REF: Guyton's physiology 22nd edition page
111, http://en.wikipedia.org/wiki/Preload_%28cardiology%29
"For cardiac contraction, the preload is usually considered to be the
end-diastolic pressure when the ventricle has become filled"
Quantitatively, preload can be calculated as
LV EDT.LV ÉDR
2h
Where LVEDP = Left ventricular end diastolic pressure, LVEDR =
Left ventricular end diastolic radius (at the ventricle's midpoint), and
h = thickness of the ventricle. This calculation is based on the Law of
Laplace.

Preload (cardiology)

In cardiac physiology, preload is the amount of sarcomere stretch experienced by cardiac muscle cells, called cardiomyocytes, at the end of ventricular filling during diastole. Preload is directly related to ventricular filling. As the relaxed ventricle fills during diastole, the walls are stretched...
