Chapter 13, Problem 4TYC
Summary Introduction
To write:
When a person cut his finger, then the pain signals are conducted to the central nervous system by the unipolar sensory neurons.The reason for the somas located near the spinal cord instead of present in the skin closer to the origin of the pain.
Introduction:
The nervous system can be defined as a highly complex portion of an animal which directs its actions and sensory messages by transmitting signals to and from diverse body parts. The basic unit of the nervous system is known as the nerve cell or neuron.

Students have asked these similar questions
The conscious perception of pain is often delayed because of the time it takes for the sensations to reach the cerebral cortex. Why would this be the case based on propagation of the axon potential?
In some cases, phantom limb pain appears to be related to the patient's perception that the phantom limb is held in an uncomfortable position.
True or False?
In the _____ pathway involving slow pain, the first neuron passes from a pain receptor to the posterior horn of the spinal cord, the second neuron crosses over and passes to the thalamus where it causes poorly localized sensations of aching pain.
options:
lateral spinothalamic
vestibulospinal
dorsal column medial lemniscal
lateral corticospinal
