Neurotransmitters can excite receptors to turn them on and stop them from transmitting.
A neuron releases a signaling chemical called a neurotransmitter across a synaptic gap to influence another cell. Any major body component or target cell that receives the signal may be another neuron, but it could also be a gland or muscle cell. These signals enable you to move your limbs, experience sensations, maintain your heartbeat, as well as receive and process all the information your body receives from other internal body components and your environment. From one neuron (nerve cell) to the following target cell, neurotransmitters transfer chemical signals, or "messages."
The majority of estimates suggest that the neurotransmitter transient lasts only a few hundred to several hundred of microseconds, indicating that post-synaptic activation is marked by a significant degree of non-equilibrium.

Polarity of a molecule does not involve the symmetry of the molecule rather it deals on with the presence of net charges and partial charges. It would be due to the partial charges present in the <span>single myosin molecules that causes its polarity. Hope this helps. Have a nice day.</span>
