The opening of calcium ions channels facilitates the migration of vesicles containing neurotransmitters in the pre-synaptic neurons to the tip of the post-synaptic membrane. at the neuromuscular junction These neurotransmitters can either be cholinergic or non-chorlinergic. At the tip of the pre-synaptic membranes the vesicles empty their neurotransmitter contents into the synapse.

The neurotransmitters, diffuse through the neuromuscular junction to bind with the receptors on the post-synaptic membrane on the post-synaptic neuron. This stimulates opening of ligand gated sodium ions, and sodium ions diffuse into the post-synaptic neuronal membrane, to cause depolarization. if the stimulus is up to the threshold levels it generate action potential.

Therefore , more calcium ions channels opening produces; more diffusion of neurotransmitters;leading to opening of more sodium channels for depolarization; and IPSP or EPSP generation.

Many kangaroo rats live in the Sonoran desert of the southwestern United States. They have a variety of adaptations for living i

SVETLANKA909090 [29]

Adaptations. The kangaroo rat is almost perfectly adapted to life in the desert. They can survive without ever drinking any water, getting needed moisture from their seed diet. They have excellent hearing and can even detect the silent sound of an owl approaching.

Hope this helps!

BTW can I have brainliest for all the effort I put into writing all of this?
