2) Painful Popping Noise at time of Injury: Sometimes when the knee is injured e.g. twisting awkwardly, there is a sudden, loud pop at the same time indicating damage to part of the knee. 3) Recurrent Painful Popping Noises not Caused by an Injury: Knee pain and popping can come on gradually with no obvious cause. If knee popping occurs without any associated pain, it is usually due to either gas bubbles building up inside the joint which burst, or ligaments/tendons snapping over the joint.
What part of a neuron was investigated in this activity? The Â±rigger zone was investgaÂ±ed. This is where Â±he axon hillock and Â±he inital segmenÂ± come Â±ogeÂ±her ACTIVITY 4: The Action Potential: Importance of Voltage-Gated Na_ Channels 1. What does TTX do to voltage-gated Na + channels?
The three main parts of a neuron are the axon, the dendrites, and the soma (cell body). The axon carries information away from the soma and transmits it to other neurons. Th â¦ e dendrites receive information from other neurons. The soma contains the nucleus of the cell and protein synthesis occurs here.
