Chapter 38.1, Problem 2CC
Summary Introduction
To explain:
The effect on sensation on the fingers, if a person had an accident that severed a small nerve required to move some of the fingers of the right hand.
Introduction:
Humans have elongated and bilaterally symmetrical body with specialized nervous system which consists of neurons axons bundles which together form the nerves and these nerves extend in the body and communicate with the cells of the body. The integration of neurons is included under the central nervous system and the travelling of information in and out of the central nervous system by neurons form peripheral nervous system. Spinal cord and brain together form central nervous system and in peripheral nervous system, ganglia and nerves act as key element.

- 1. Make a model or draw 3 multipolar neurons. Imagine you had something crawling on your arm. The first is a sensory neuron, getting its information from the skin and sensing the movement. The second is an interneuron. It relays information from the first (sensory neuron) to the CNS. The third is a motor neuron. It begins in the CNS but leads all the way to the muscle, so that you can move the fingers and scratch the area. On your images/model the "dendrites" should be blue, "axon" should be green and "soma" should be yellow. As you connect them to each other, take notice in which areas are the receiving end, and which are the transmissive ends.arrow_forwardHi, Descending pathway that inhibit pain stimulates inhibitory interneueons in the spinal cord.
