What is a chemicals travel through the bloodstream and affect the activities of other cells?
I suppose that you think to oxygen.Oxygen is indispensable for life.
What is Diffusion of transmitters across synaptic cleft?
It is when neurotransmitters are released form one neuron and travel across the synapse, which is a gap between two neuron, in order to stimulate the second neuron
Which is the space that separates two neurons?
Synapses
How does a message jump across the synaptic gap and passes to the next neuron?
Nerve impulses, which are electrical, do not jump across the synaptic gap at synapses. Instead, the arrival of a nerve impulse at the axon terminal triggers the release of chemicals called neurotransmitters from the axon terminal into the synaptic gap, the nerve impulses then travel across the chemicals to the place where it needs to go to
What is the result of sodium ions moving across the axons membrane during an action potential?
a neural impulse(electrical impulse) is released and it travels down the axon of a neuron to the axon terminals. At the axon terminal there are sacs called synaptic vesicles which contain chemicals called neurotransmitters. When the neural impulse reaches the terminal it causes the sacs to move closer to the membrane of the axon terminal and release the neurotransmitters inside. Then neurotransmitters travel across the synaptic gap and stimulate the dendrites of another neuron and the whole process starts again.

Is a minute gap between a neuron and target cell across which neurotransmitters travel?
Synaptic cleft
Why are hormones called chemical messengers?
I believe they are called chemical messengers because of their function and the fact it is a chemical. They travel through the blood and target cells respond to hormones often because of their structure. I have read in a science book (McDougal Littell 's Human Biology) that they are called chemical messengers because they are made at one location and function at another.
What is the area between neurons across which nerve impulses travel?
no, synapse. node of ranvier is between axon and dendrites
What is Diffusion of transmitters across synaptic cleft?
It is when neurotransmitters are released form one neuron and travel across the synapse, which is a gap between two neuron, in order to stimulate the second neuron
How do hormones coordinate body functions?
Hormones are chemical messengers that travel throughout the body and control the functions of the body. Small amounts of hormones can trigger large responses in the body.
What is the chemical that moves from the axon of one neuron across a gap to the dendrite of another?
Neurotransmitters. (don't have any idea what the original answer below is doing here.)

What is released when an impulse reaches the end of a neuron?
The impulse ends in the terminal or synaptic knob. Here neurotransmitters are put in vesicles and travel across the synaptic cleft to the next neuron.
How does a message. travel across the gap. at a synapse?
it is sent through the neurotransmittersAt the synaptic terminal an electrical impulse will trigger the migration of vesicles containing neurotransmitters toward the presynaptic membrane.
Which is the space that separates two neurons?
Synapses
What are chemical messengers that allow an organ to send signals to another distant organ in the body through the blood?
There are many hormones that travel this way. Thyroid, sex hormone and ACTH are a few.
How does a signal cross from the axon of the neuron to the receiving cell?
When the electrical signal reaches the end of an axon, neurotransmitters are released. They travel across the synapse. Once they reach the receiving cell, they create a new electrical signal.
