The five senses for kids – preschool education
Sensitive Senses Sensory receptors are nerve system extensions. Specialized cells or processes that transmit unique information are present. The stimulus must be converted into an action potential by a receptor (transductions) From the receptor to the CNS, the AP must travel. 2
The senses of the general and special Touch, pressure, vibration, pain, temperature, proprioception, and chemical and fluid pressure are all examples of general senses. Olfaction, gustation, vision, hearing, and equilibrium are all special senses. 3
7 Lingual Papilla is a type of papilla found in the mouth. Papillae are epithelial projections on the tongue’s superior surface. Around 100 taste buds are present in the circumcumvallate papilla. Around 5-10 taste buds are found in fungiform papilla. Filiform papillae provide pressure for the tongue to pass things around in the mouth, but they don’t contain taste buds.
9 Receptors for Taste Spindle-shaped cells make up the taste buds. Daughter cells are produced by basal cells and mature in stages. Gustatory cells use a taste pore to expand microvilli into the surrounding fluids. Keep the taste receptors contained.

An Overview of the Special Senses
Visual pathway and lesions
Learning Objectives 17-1 Describe the physiological basis of olfactory discrimination by describing the sensory organs of smell, tracing the olfactory pathways to their destinations in the brain, and tracing the olfactory pathways to their destinations in the brain. 17-2 Describe the anatomical basis of gustatory discrimination by identifying the gustatory sensory organs, tracing the gustatory pathways to their destinations in the brain, and tracing the gustatory pathways to their destinations in the brain. 17 to 3 Identify the eye’s internal and accessory structures, as well as their features.

Subsistance is being smelt. A transformed neuron with several cilia extending from its free surface is an olfactory receptor. 9
