Answer:
1. Sympathetic input increases ventricular contractility, thereby increasing stroke volume.
2. Sympathetic input decreases conduction time within the heart, decreasing the delay between atrial and ventricular contractions.
3. Sympathetic input increases the speed of ventricular contraction.
Answer: Inclusions or inclusion structures serve as temporary storage of molecules like glycogen and melanin.
Inclusion structures are the aggregates formed of specific molecule types.
The inclusion bodies serve the purpose of temporary storage for molecules such as proteins, lipids, glycogen and melanin. One of the major differences between cell organelle and cell inclusion is that organelles are the living components or subcomponents which have particular functions but cell inclusions are non-living compounds or by products of metabolism process present in the cytoplasm.
