20 points! this is an anatomy question. at a myoneural junction, what is the function of the motor end plate? to release neurotransmitters that travel toward the axon terminal to bind neurotransmitters and generate an action potential in the sarcolemma to release sodium and potassium that travel toward the axon terminal to bind sodium and potassium and generate an action potential in the sarcolemma

To bind neurotransmitters and generate an action potential in the sarcolemma

Explanation:

A Myoneural junction is also known as A neuromuscular junction that basically is a chemical synapse which is created when a  motor neuron contacts a muscle fiber. This  synapse made between a spinal motor neuron and skeletal muscle cell has a specific structure due to which it is called the motor endplate.

Now what is the function of this motor endplate?

We already know that in response to a stimuli a series of events start in nervous system which lead to the production of a response. For example, when we touch a hot object a signal travels through Central nervous system and the response occurs when we move our hands away from the hot object.

Now, taking this same example, what happens is that when a response has to be produced , for example muscle contraction, the neurons which act there are called motor neurons. When the motor nerve is stimulated due to arrival of a nerve impulse in the motor nerve terminals, the first response occurs with the help of motor endplate.

The arrival of motor neuron causes an action potential at presynaptic neuron terminal that opens up  calcium channels and Ca2+ ions  into the presynaptic neuron's cytosol causing several neurotransmitter molecules to fuse with the presynaptic neuron's cell membrane

Here, the neurotranmsitters like acetylcholine binds with the receptors present in the motor end plate. As soon as they bind with the receptors on motor end plate,  an influx of Na+ ions occurs that  triggers an action potential. When action potential is triggered it  travels along the sarcolemma and into the muscle fiber which initiate the muscle contraction. This muscle contraction is the response to a certain stimuli and in the example we discussed it will be bringing our hand away from the hot object.

This is a long and complex mechanism which i tried to summarize, You can get a better idea by looking at the diagram attached.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

deforestation                                                         contour plowing

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
