Soil
Soil is the upper layer of the ground comprising of a mixture of sand, silt, clay, loose rock fragments, and organic matter that can support the growth of rooted plants. The relative proportions of sand, silt and clay determine the texture and size of the pores of the soil, which affects its ability to allow air and water to penetrate/infiltrate.
They are in response to the environment. Both are homoeostatic mechanisms that lower the core temperature of the body in response to an increase in body temperature. This is an example of 'negative feedback'.
The synapses that are nearer to the axon hillock would bring the initial segment closest to the threshold based on spatial summation.
<h3>What is neuron synapsis?</h3>
In neurosciences, the term synapsis makes reference to the connection between two nerve cells (neurons).
Synapsis is produced by the connection between axons and dendrites among different neurons.
Spatial summation refers to the start (trigger) of the action potential in neurons via two or more presynaptic cells.
