Which neurons are responsible for acting as a facilitator of communication between neurons?
Neurotransmitters are the chemical medium through which the signals move from one neuron to the next at the synapses. This is called neurotransmission and the way it is done is through electrochemical processes. A chemical message from other neurons, through dendrites causes a nerve impulse. This travels down the Axon to the terminal buttons at the end. This then releases the neurotransmitters which send a message to the next neuron. The neuron that sends the message is the pre-synaptic neuron, and the one that receives it is the postsynaptic neuron. Each neurotransmitter has a specific effect on a specific circuit. They do not all work with every receptor. This is a complicated subject to try to explain in a short statement! I have probably confused you by now.
If a child is watching a favorite sibling getting scolded for misbehavior which type of neuron is likely to be activated in an empathetic response to this observation?
In short - there is no one type of neuron that would be activated; there would be many types across a number of regions such as those involved in appreciation (temporal association areas, occipital cortices, prefrontal areas) as well limbic areas involved in emotion (amygdala, orbifrontal cortex, raphe nuclei, locus coerules and the hippocampus). It's the Mirror Neuron
What works by increasing activity in certain areas of the brain to increase concentration and wakefulness?
Orexin increases activity in certain areas of the brain to increase concentration and wakefulness. Orexin reacts with norepinephrine neuron receptors.

Can agonists or antagonists that mimic neurotransmitters be mistakenly stored in terminal buttons during reuptake?
Some neurotransmitter molecules have a molecular structure that precisely fits the receptor site on the receiving neuron, much as a key fits a lock. When the agonist molecule excites, it is similar enough in structure to the neurotransmitter molecule that it mimics its effects on the receiving neuron. Morphine, for instance, mimics the action of endorphins by stimulating receptors in brain areas involved in mood and pain sensations. This antagonist molecule inhibits. It has a structure similar enough to the neurotransmitter to occupy its receptor site and block its action, but not similar enough to stimulate the receptor.
Does information enter a neuron through the axon?
The different ion concentrations on the inside and outside of the cell membrane create a certain electric potential around the cell (just by being there with their charge). A strong enough change in the concentrations can cause certain ion channel proteins in the membrane to open all at once, allowing certain ions to massively diffuse through the membrane and thereby rapidly changing the potential. When a certain potential is reached, these channels will begin to close again and different potential-controlled channels will open, allowing a different kind of ions to move through the membrane and returning the membrane potential back to the previous state. Again through diffusion the now changed ion concentrations will trigger these so-called action potentials in nearby membrane regions, carrying the stimulation along the neuron's axon to the next neuron.

What physical abnormalities in the brain are sometimes present in schizophrenics?
These include atrophy or degeneration in some brain areas and enlargement of fluid-filled cavities called ventricles. Schizophrenics also have abnormalities in chemical neurotransmitters the brain normally uses to communicate information
Describe briefly how the particular structure of a neuron relates to its function?
A neuron has a cell body (soma), dendrites(inputs), and an axon (the output).Neurons can send signals to one another across small gaps between them called synapses; if enough signals are received and go down the dendrites and reach a trigger point on the soma, a spike, or impulse, called an action potential will fire along the axon to its end, which will cause neurotransmitters to be released into a synapse, sending the signal onward.
What are the light and dark areas on the moon?
the light areas of the moon are called the highlands. the dark areas are called maria.
What glands produce sebum?
Sebaceous Glands in the dermal layer of your skin make sebum. These glands are located at the base of hair follicles and helps keep the skin from drying out.Thus, these glands are located in hair-bearing areas such as the face, axillae, and groin.The gland that secretes sebum is called the "sebaceous gland" and it can be found in the skin of mammals and secretes that oily substance called sebum into the mammal's hair follicles and sometimes into the skin for lubrication.sebaceous glands.
