Describe the function of a triggering center in a neuron.
Describe the function of a triggering center in a neuron.
Homework Answers
The triggering centre occurs at chemical synapse. At chemical neuro-transmission, presynaptic neuron and the post-synaptic neuron are separated by a small gap which is called a synaptic cleft. It is filled with extracellular fluid . Although very small, i.e. a billionth of a meter, the synaptic cleft generates a physical barrier for electrical signal carried by a neuron to be carried over to another neuron. In electrical terminology, the synaptic cleft is considered

1) a. Define the threshold potential for a neuron. Describe what will occur in a neuron when the membrane reaches potentials lower (more negative) and higher (less negative) than the threshold, and why. b. Describe why action potential propagation is unidirectional, and why myelin increases the speed of action potential propagation.

Question 4: Impulse Transmission Between Neurons Nerve impulses travel from neuron to neuron. Describe this mode of propagation, and draw a model to supplement your description. Explain how it differs from the mode of propagation along the neuron.

What is the function of the longest extension on a neuron? A. Support the function of a neuron. B. Interpret whether a signal needs to be continued and sent to other cells. C. Receive signals from other neurons and send them to the cell body. D. Send signals away from the cell body to other neurons muscle cells, or gland cells.

describe how the neurotransmitter is synthesized in the presynaptic neuron, how it is released (mechanism of vesicular release), how it affects the postsynaptic cell (excitation or inhibition) and how it is degraded or recycled.

A neuron has three main parts: dendrites, cell body, and axon. A neuron may send signals to other neuron or other tissues (effectors). Describe how the signal moves from one point to the other.
