On which direction does an impulse go across a synapse?
An impulse travels in one direction across a synapse, from the presynaptic neuron to the postsynaptic neuron. This ensures that the signal transmission in the nervous system is unidirectional.
What carries an impulse across a synapse to a muscle?
neurons?
A small space across which an impulse travels to move from one neuron to another?
It is most definitely a synapse.
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 the difference between impulse conduction and transmission?
Impulse conduction refers to passage of impulse within the same cell. Where as transmission as the name implies, is concerned about passage of impulses either chemical or electrical from one cell to another.
What is a small space across which an impulse travels to move from on neuron to another?
It's most likely called a synapse
How does an impulse cross a synape?
An electrical impulse travels along a nerve until it hits a synapse, where it causes the release of chemicals (neurotransmitters) which migrate across the synapse. At the other side , these neurotransmitters activate receptors which cause an electrical signal to continue along the nerve.
What is A small space across which an impulse travels to move from one neuron to another?
Synapse. The gap itself is called the synapticcleft.
Which of the following helps carry nerve impulses across the synapse?
neurotransmitter carries the nerve impulses from neuron to neuron across a synapse
What location does a neuron transfer an impulse to another cell?
It depends on what the next structure is. If it is another neurone, then it is a synapse. If it is skeletal muscle, then the it is a neuromuscular junction. If it is any other type of muscle, then it is a myoneural junction.
A nerve impulse is carried across a synapse by?
neurotransmitters, which are chemical messengers that transmit signals between neurons. When a nerve impulse reaches the end of a neuron, it triggers the release of neurotransmitters into the synapse. These neurotransmitters then bind to receptors on the neighboring neuron, initiating a new nerve impulse to continue the signal transmission.
How is a stimulus transmitted across a synapse?
Neurons are responsible for transmitting a stimulus across a synapse. The electric potential of the neuron is sensitive to changes in the resting state and sets off electric transmissions.
