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
Why is synapse important to the nervous system?
Synapses are important because they enable signal transmission in the body. These signals are the nerve impulses, which go across and between neurons. This process occurs in the synaptic cleft of the central nervous system.
What type of messages travel from nerve cells?
They go through synapses.
Where do soundwaves go after the auditory ossicles?
Soundwaves enter the outer ear (auditory canal) and strike the tympanic membrane (eardrum).Soundwaves vibrate off the eardrum and are transmitted by the ossicles to the oval window.These become fluid vibrations of the inner ear and are picked up by the mechanoreceptors, converted into an electrical impulse and sent to the brain for interpretation.
How are ears attached to your brain?
Ears are connected to the brain through the auditory nerve, which carries signals from the inner ear to the brain for processing. This nerve transmits sound information as electrical impulses to the brain, allowing us to perceive and interpret sounds.

Describe the general structure of a synapse?
Synapses occur between two neurons. Electrical activitiy in the pre-synaptic neuron influences the post-synaptic neuron. There are two types of synapses in the body: Electrical and chemical. Electrical synapses occur in pre and post synaptic neurons that are joined via gap junctions. Currents from action potentials flow across the junction through channels called connexons. This current will depolarize the membrane of the post synaptic neuron to threshold, which will continue the action potential in the cell. Electrical synapses are fast and bidirectional. However, they are mainly found in cardiac and smooth muscles, and not in the mammalian nervous system.Chemical synapses use neurotransmitters. Depolarization occurs in the pre-synaptic neuron and calcium ions rush in. The calcium ions activate neurotransmitter release into the synaptic cleft. The neurotransmitters reach the post-synaptic neuron and cause action potentials to develop.Note: this can go into much more detail

Why braincells die when someone gets frustrated?
Either too much electrical impulses go throught the brain, and "fry" the cell or too much pressure builds up and causes the cell to die.
State why there is a brief delay in the transmission of an impulse across the synapse?
The impulse must go from one neuron to the next. To do this, it must change from an electrical to a chemical signal, and back to an electrical signal when it reaches the next neuron. Electrical signals are impossibly fast, but neurotransmitters cannot cross a synapse that fast. So, the impulse is at its slowest point when it crosses the synapse.
What is a neuron identify the parts of the neuron and their functions?
there's the axon (the nerve) the electrical impulse goes down that and covering the axon is the myelin sheath, otherwise known as a fatty sheath which insulates and helps make the electrical impulse go faster. In between each myelin sheath there are synapses (gaps between each one) and the impulse has to cross the gap so neurotransmitters are released which bind to receptors on the other side creating another electrical impulse which makes it travel even faster.
What impulse conduction is the fastest in neurons?
Axons conduct the nerve impulses. Dendrites receive the impulses. Possible the impulses go through the dendrites faster, though the synaptic cleft may slow this pathway. Dendrites are much shorter than axons.
Which way to rows go?
THEY GO ACROSS NOT UP AND DOWN. THAT IS FOR COLUMNS.
Do latitude lines go up and down or across?
Latitude lines go -------- (across) And Longitude goes | | | (up & down)

What does an electrical engineer like to do?
When I was an electrical engineer, I liked to go gliding at the weekend.
