What neuron is before a synapse?
The synapse consists of the two neurons, one of which is sending information to the other. The sending neuron is known as the pre-synaptic neuron (i.e. before the synapse) while the receiving neuron is known as the post-synaptic neuron (i.e. after the synapse).
What is the difference between the way excitatory and inhibitory transmitters work?
As a rule more than one presynaptic action potential is needed to fire the postsynaptic neuron or muscle so that the trigger to initiate an action potential are either many subthreshold local potentials from different sources or from the same neuron received within a short period of time. The first case is called spatial summation and the second case is called temporal summation. Whether a postsynaptic potential (another term for a local potential) is excitatory or inhibitory depends on what ion channels are affected by the transmitter released from the presynaptic vesicles.
what are the differences between pre-synaptic and post-synaptic neuron?
Yes. A synapse by definition is the space (gap) between one neurons terminal buton and another neurons dendrites. So, the neuron with the terminal buton end is known as the pre-synaptic neuron and the neuron after the synapse is known as the post-synaptic neuron.
What is the difference between a motor unit and a motor neuron in the context of muscle movement?
A motor unit consists of a motor neuron and the muscle fibers it controls. The motor neuron sends signals to the muscle fibers to contract, while the motor unit refers to the combination of the neuron and the muscle fibers it innervates.
What are the differences between axodendritic and axosomatic synapses in terms of their structure and function?
Axodendritic synapses occur between the axon terminal of one neuron and the dendrites of another neuron, while axosomatic synapses occur between the axon terminal and the cell body (soma) of another neuron. In terms of structure, axodendritic synapses are more common and allow for communication between neurons, while axosomatic synapses are less common and are involved in regulating the firing of the postsynaptic neuron.
What effect do neurotransmitters from one neuron have on the next neuron?
Neurotransmitters released from one neuron can either excite or inhibit the next neuron. Excitatory neurotransmitters make the receiving neuron more likely to fire an action potential, while inhibitory neurotransmitters make it less likely. This process allows for communication and coordination between neurons in the nervous system.

Does A neuron expends energy while it maintains a resting potential?
yes it does
what are the differences between pre-synaptic and post-synaptic neuron?
Yes. A synapse by definition is the space (gap) between one neurons terminal buton and another neurons dendrites. So, the neuron with the terminal buton end is known as the pre-synaptic neuron and the neuron after the synapse is known as the post-synaptic neuron.
Why it is more difficult to initiate an action potential during the relative refractory period?
During the relative refractory period, the neuron is hyperpolarized due to the prolonged opening of potassium channels, making it harder to reach the threshold for firing an action potential. While some sodium channels are reset and can respond to a stimulus, the increased negativity inside the cell means that a stronger-than-normal stimulus is required to depolarize the membrane sufficiently. This period ensures that action potentials occur in a controlled manner, preventing excessive firing and allowing the neuron to recover.

A motor unit consists of a motor neuron and the muscle fibers it controls. The motor neuron sends signals to the muscle fibers to contract, while the motor unit refers to the combination of the neuron and the muscle fibers it innervates.
