Question
Chapter 39, Problem 12TYK
Summary Introduction
To review:
In case of some vertebrates, nasal epithelium synapse directly with the brain neurons that activate behavioral responses to odors. Reviewing the reason for this type of development in animals favored by natural selection.
Introduction:
Animal brains are filled with neurons in which analysis of stimulus, that comes from all over the body takes place. Sensory neurons are associated with sensory organs such as skin, or other sensory organs. They carry impulse to the CNS (central nervous system), that is, the brain and the spinal cord. Motor neuron carries impulse or messages from the brain to the muscles hence, known as a motor neuron. Interneurons are present between these two neurons and they relay and carry electric impulses in between the central nervous system.
