Anatomy and Physiology of Special Sensory Organs
Sensory organs can be labeled as special sensory structures that permit sight, hearing, odor, and flavor. Sensory structures permitting proprioception, touch, thermal, and pain perception can be classified as more advanced sensory organs. The sensory neurons are trained to find out modifications in the external and internal conditions so that a person's body can react to that change. A stimulus is the first signal that is recognized by any sensory receptor of the body. Stimulus is an impulse generated when there is a change in the surroundings of a person. For example, a heated environment will alert the brain through the thermal sensory organs and generate a reflex accordingly.
Sensory Receptors
The human sensory system is one of the most complex and highly evolved structures, which processes a myriad of incoming messages. This well-coordinated system helps an organism or individual to respond to external stimuli, appropriately. The sensory receptors are an important part of the sensory system. These receptors are specialized epidermal cells that respond to external environmental stimuli. These receptors consist of structural and support cells that form the peripheral unit of the receptor and the neural dendrites which receive and detect the external stimuli.
What are the causes, clinical manifestations, and management of smell and taste disorders?
Smell and taste disorders mean the person will face difficulty in smelling odors and difficult to distinguish between different tastes like sweet, sour, salty, bitter, etc.
1) CAUSES OF SMELL AND TASTE ODORS:-
a) Respiratory problems like sinus or asthma diseases can lead to these problems.
b) Some oral infections or dental surgeries can lead to these taste and smell disorders.
c) These disorders can also develop due to ongoing aging.
d) Another cause can be due to some aggregated mass or polyps which is the main reason for olfactory dysfunctioning.
2) CLINICAL MANIFESTATIONS OF SMELL AND TASTE ODORS:-
Cannot recognize differences in smell or taste of different flavors like sweet, sour, etc. Some people recognize pleasant taste as unpleasant.
