This Medical Lecture of Physiology at sqadia.com by Abdul Wasay follow standard book of medicine “Guyton and Hall Textbook of Medical Physiology” by John E. Hall. In this lecture ´´The Chemical Senses: Taste and Smell´´ is explained.
Sense of Taste
Section one is about ´´Sense of Taste´´. Educator’s prime focus is the elucidation of primary sensations of taste. In the next few slides different types of taste are discussed. Finally taste blindness is the subject of discussion.
The Taste Bud and its Function
Section two is about ‘’The Taste Bud and its Function’’. Educator reveals the location of the taste buds. After that specificity of taste buds is pursued. Then information is delivered on generation of nerve impulses.
Transmission of Taste Signals
Section three is about ‘’Sense of Smell’’. Initially taste reflexes are explained. Next is the rapid adaptation of taste. Then educator notify about taste preference.
Sense of Smell
Section four is about ‘’Transmission of Smell Signals’’. The very first slide of this section is the elucidation of olfactory membrane and cells. In the next slide mechanism of excitation is illustrated. At the end threshold for smell is discussed.
Transmission of Smell Signals
Section five is about ‘’Transmission of Smell Signals’’. Educator’s prime emphasis is on Transmission of olfactory signals. This is followed by the primitive and newer olfactory pathways. Finally, the less old olfactory system is highlighted.
