--Synaptic Vesicles
The tiny sacs in the synaptic knob are known as synaptic vessels. The synaptic vessels release chemicals into the bloodstream with each synapse.
The exchange of gases inside the lungs actually occurs inside tiny sacs called alveoli. These alveoli are surrounded by capillaries where oxygen from inhaled air diffuses into the bloodstream, and carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled.
A synapse, chemical signals called neurotransmitters cross these gaps, carrying on the signal.
The space between nerve cells is called a synapse. It is the junction where electrical signals are transmitted from one nerve cell to another through neurotransmitter molecules.
are called synaptic vesicles. They contain specific neurotransmitters that are released into the synaptic cleft when the nerve impulse reaches the end of the axon. The neurotransmitters then bind to receptors on the neighboring neuron, continuing the signal transmission.

Neurotransmitters are stored in tiny sacs called synaptic vesicles within the axon terminals of neurons. When an action potential travels down the neuron, these vesicles release neurotransmitters into the synapse, where they can then bind to receptors on the adjacent neuron.
The tiny sacs are called alveoli and are basically the lungs.
These "tiny sacs" are called vacuoles, but there are many other vacuoles that contain things other than starch.
