Nerve cell bodies found outside the central nervous system are called tracts nerves neurons ganglia

A group of nerve cell bodies outside the central nervous system of the body is called as ganglion. The nerve is an enclosed cable like bundles of axons. A neuron is a nerve cell (electrically excitable) that receive, process and transmit signalling information through electrical and chemical signals. The tracts are the bundle of fibers that connects nuclei of the central nervous system. The nerves, neuron and tracts are present outside the central nervous system. Hence, only ganglia persists in the central nervous system.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
