On the first day, he is bitten by some kind of cat-like creature with bird legs, and he starts to feel like he can no longer pinpoint exactly where pain is coming from on his body. You, a hotshot physiologist with incredible measurement tools, do a fullbody scan of Ezra's neurons and you find that the cat-like creature's bite has caused the breakdown of his "collaterals". Ezra is a bit of a physiology novice and asks you explain what the breakdown of collaterals would cause him to no longer be able to pinpoint the source of pain on his body.

Question: Scenario: Your buddy Ezra is a space explorer who has landed on an unexplored planet, where his job is to catalogue the organisms that live there. On the first day, he is bitten by some kind of cat-like creature with bird legs, and he starts to feel like he can no longer pinpoint exactly where pain is coming from on his body. You, a hotshot physiologist with incredible measurement tools, do a fullbody scan of Ezra's neurons and you find that the cat-like creature's bite has caused the breakdown of his "collaterals". Ezra is a bit of a physiology novice and asks you explain what the breakdown of collaterals would cause him to no longer be able to pinpoint the source of pain on his body.

Expert Solution
Step 1: Introduction:

Ans. When Ezra was bitten by the cat-like creature, it resulted in the breakdown of his "collaterals". In the context of sensory neurons, collaterals are the branched extensions that allow a single neuron to communicate with multiple interneurons or other sensory neurons.
