What else can I help you with?
What type of synapse uses neurotransmitter?
Chemical Synapse
What Chemical enters a muscle cell upon excitation?
Acetylcholine is the chemical that crosses the synapse causing a muscle to contract. It is released due to an electrical impulse sent from your brain down your nervous system.
What is the difference between Neuron and synapse?
A neuron is a nerve cell. A synapse is a gap between the sending and receiving neurons, where there are neurotransmitters responsible for transporting chemicals to the receiving neuron. (A neurotransmitter is a chemical messenger.)
What is the small space between one neuron and the next is called?
A synapse, chemical signals called neurotransmitters cross these gaps, carrying on the signal.
How does the impulse jump the synapse?
Chemical diffusion
What is the role of neurotransmitter at a chemical synapse?
exocytosis
What type of chemicals moves across the space between two nerve cells?
chemical synapse
A synapse is an a chemical messenger that triggers muscle contractions?
YES IN SORTS...A SYNAPSE IS THE RELEASE STRESS IN NERVE ENDINGS....USUALLY HAPPENS RIGHT BEFORE YOU FALL ASLEEP....SORTA LIKE THEY R WINDING DOWN FOR THE NIGHT...( IM SURE YOU FELT THE JUMPS OR CONTRACTION WHILE YOU ARE FALLING ASLEEP)
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.
Which type of synapse dominates the nervous system?
Chemical
What is the chemical secreted into the gap between neurons at the synapse?
The answer is NEUROTRANSMITTER.
Why do chemical messengers get information from synapse?
They act as an active "bridge".
