How many senses are possessed by a human?  1. Sight, 2.Smell, 3.Taste, 4.Touch, and 5.Hearing, Humans also have: 6. Absolute Musical Pitch Sensation, i.e., Perfect Pitch. (It’s rare but it’s a sense) 7. Balance (equilibrioception), 8.Pressure, 9.Temperature (thermoception) 10.Pain (nociception) 11.Pleasure, 12. Extreme Pleasure (Dopamine/VMAT2 sensors), 13. Acceleration 14. Proprioception is the sense of the relative position of neighboring parts of the body and strength of effort being employed in movement. It is distinguished from:  15. Exteroception, by which we perceive the boundaries of the outside world, 16. Interoception, by which we perceive pain, hunger, etc., and the movement of internal organs, 17. Kinesthesia,  18. Synesthesia, in which one type of stimulation evokes the sensation of another. For example, the hearing of a sound may result in the sensation of the visualization of a color, or a shape may be sensed as a smell. Synesthesia is hereditary and it is estimated that it occurs in 1 out of 1000 individuals with variations of type and intensity. The most common forms of synesthesia link numbers or letters with colors and 19. a sense of being poisoned which in turn causes nausea.

are neurologically linked to the brain.

  • 20. Pulmonary stretch receptors are found in the lungs and control the respiratory rate.
  • 21. Peripheral chemoreceptors in the brain monitor the carbon dioxide and oxygen levels in the brain to give a feeling of suffocation if carbon dioxide levels get too high.[14]
  • 22. The chemoreceptor trigger zone is an area of the medulla in the brain that receives inputs from blood-borne drugs or hormones, and communicates with the vomiting center.
  • 23. Chemoreceptors in the circulatory system also measure salt levels and prompt thirst if they get too high (they can also respond to high sugar levels in diabetics[15]).
  • 24. Cutaneous receptors in the skin not only respond to touch, pressure, and temperature, but also respond to vasodilation in the skin such as blushing.
  • 25. Stretch receptors in the gastrointestinal tract sense gas distension that may result in colic pain.
  • 26. Stimulation of sensory receptors in the esophagus result in sensations felt in the throat when swallowing, vomiting, or during acid reflux.
  • 27. Sensory receptors in pharynx mucosa, similar to touch receptors in the skin, sense foreign objects such as food that may result in a gag reflex and corresponding gagging sensation.
  • 28. Stimulation of sensory receptors in the urinary bladder and rectum may result in sensations of fullness.
  • 29. Stimulation of stretch sensors that sense dilation of various blood vessels may result in pain, for example headache caused by vasodilation of brain arteries.

 

But there is no Common Sense. There’s no sense of Manners, of Taste in clothes or designs, nor are there other senses although some people ascribe things like ESP to a so-called sixth sense. Many attributes which humans display are not from the body, i.e., from the senses but from the mind. The mind is a self-assembling mechanism according to Stephen Pinker, an honored Cognitive Neuro-Science researcher. The mind shapes itself and can regress, stagnate or improve itself.
