Plicae, villi and microvilli increase the surface area for he absorption of nutrients
The Experiment name is 'swan neck flask'.
Since only one of his two treatments employed the same type of nutritious broth and flask, only one of his two treatments was exposed to preexisting cells.
Nutrient Broth- A common culture medium for undemanding microorganisms is nutrient broth. Numerous standardized techniques for analyzing meals, dairy products, water, and other items advocate it.
Pre-existing Cell- All cells originate from previously existing cells, according to the third component of the cell theory definition. This implies that cells are not created spontaneously, as the term "spontaneous genesis" implies. Current cells are constantly used to create new ones.

Motor and associative neurons can receive information from many different sources simultaneously because of their profusion of highly branched dendrites.
<h3>What are Dendrites?</h3>
- Dendrons, which are also known as dendrites, are branched protoplasmic extensions of a nerve cell that transmit the electrochemical stimulation that the cell body, or soma, of the neuron from which the dendrites project, receives from other neural cells.
- Through synapses, which are distributed throughout the dendritic tree, upstream neurons (often via their axons) transmit electrical stimulation onto dendrites.
- Dendrites are essential for integrating these synaptic inputs and controlling how much an action potential is generated by a neuron.
- A multi-step biological process called dendritic arborization often referred to as dendritic branching, is how neurons grow new dendritic trees and branches to produce new synapses.

In neurogenic shock, the characteristic mechanism is the reduction of sympathetic outflow from the brainstem leading to the decreased in the blood vessel tone and eventually vasodilation. In the presence of vasodilation, there will be decreased blood pressure and eventually shock. Since there is reduced sympathetic outflow, there will also be a decreased heart rate, warm skin (from the vasodilation), and dry skin (from the reduced cholinergic stimulation of the sweat glands).
