Mr. Reginald, a senior medical laboratory technician was enjoying a bowl of kokonte with goat groundnut soup after a hard day’s work, when he was rudely interrupted by a female anopheles mosquito which was also enjoying his sweet rich A+ blood from his left leg. Perceiving the pain processed by the somatosensory cortex, he studied the mosquito’s position and quickly laid hands on it resulting into its death. How was the pain perceived by Mr. Reginald Describe how he voluntarily killed the mosquito.
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.
