The synapse releases a chemical that can diffuse across the gap between two neurones. The synapse has a large surface area, which means diffusion of the chemical can occur at a higher rate.

How are living organisms adapted to increase posibility of diffusion?
they have a large surface area and are important
What is an electrical synapse?
Chemical synapses are much slower to react to stimuli. However chemical synapses transmit a signal with constant strength or even a signal that get stronger. This is called "gain." Electrical synapses are faster but have no "gain," the signal gets weaker as it travels along the synapse to other neurons. Electrical synapses are only used for applications where a reflex must be extremely fast. They are simple and allow for synchronized action. A benefit of electrical synapses is they will transmit signals in both directions. Chemical synapses have many important advantages as well. They are more complex and vary their signal strengths. Their functions are influenced by chemical outputs in the nervous system. Chemical synapses are the most common type.
It is said that synaptic connections form so quickly in the babys brain that by the time the baby is three it will have twice as many synapses as it will need later on How are these extra synapses?
they are eliminated when they are not used
How the brain connects things together?
With the Nervous System.
Molecules tend to move from an area where they are more concentrated to an area where they are less concentrated This process is called?
Diffusion
How is a fish specialy adapted to exchange gases by diffusion?
XD
What are the parts of the body that adapted to aid diffusion?
lung and heart
How are living organisms adapted to increase posibility of diffusion?
they have a large surface area and are important
How do electrical impulses go across synapses?
An electrial nerve impulse travels across a synapse by diffusion. The neurotransmitter substance from the pre-synaptic cleft travels across the synapse via diffusion. This is then received by receptors in the post synaptic cleft
How is Alveoli well adapted to diffusion?
The alveoli have very thin walls, which allow for rapid diffusion into the surrounding capillaries. There are also many alevoli in the lung, and that increases the surface area dramatically, allowing for more diffusion to occur
How alveoli adapted to their jobs?
adapted by having a big surface area so it can absorb more oxygen and it contains lots of oxygen. Also it has very thin tubes for diffusion.
Where does synapses take place?
The synapses take place in the spinal cord
Are there synapses in peripheral nervous system?
There are synapses between each and every neuron in the entire nervous system; so yes, there are synapses in the peripheral section of the nervous system.
What are the reaction that having a great time leaping across synapses?
There are no reactions, the end of a nerve produces a gas that goes across the synapses and creates the electrical impulse on the other side of the synapses and continues the message!
What has the author U Sandbank written?
U. Sandbank has written: 'The development of synapses' -- subject(s): Nervous system, Synapses
Which system involves a synapse?
All nerves have synapses, which are where the nerve junctions are located, so the nervous system involves synapses.
What reactions leap across synapses?
Reactions don't leap across synapses but neurotransmitters will diffuse across the synaptic cleft.
