The senses

Human senses is a concept that has been defined and defined differently for millennia, in modern english being defined a certain way and referred to as "the senses".G.

In fact, the five traditional senses are not the only senses we have. There are more body senses, of which at least three would be of interest for meditators: The vestibular sense, the proprioceptive sense, and the interoceptive sense.
The vestibular sense keeps track of the position of the body and body parts in the space and is in charge, among other things, of keeping the equilibrium. Its training is essential in dancing and in martial arts. The vestibular sense, together with the proprioceptive sense, is the focus of the moving meditations, like Tai Chi and the Sufi Sema.
The proprioceptive sense works in close cooperation with the vestibular sense and is in charge of detecting the activity of the body and perceiving signals such as muscle tension, body temperature, and the like. It is much the focus of the asana practice of Hatha Yoga.
To complete the somatosensory system, we have the interoceptive sense, which perceives the visceral activity generated by the autonomic nervous system, such as gut contractions and vascular dilatation.

A sense is a capacity of creatures that provides data for perception. The senses and their operation, classification, and theory are overlapping topics studied by a variety of fields, most notably neuroscience, cognitive psychology (or cognitive science), and philosophy of perception. The nervous system has a specific sensory nervous system, and a sense organ, or sensor, dedicated to each sense.
Humans have a multitude of sensors. Sight (vision), hearing (audition), taste (gustation), smell (olfaction), and touch (somatosensation) are the five traditionally recognized senses. The ability to detect other stimuli beyond those governed by these most broadly recognized senses also exists, and these sensory modalities include temperature (thermoception), kinesthetic sense (proprioception), pain (nociception), balance (equilibrioception), vibration (mechanoreception), and various internal stimuli (e.g. the different chemoreceptors for detecting salt and carbon dioxide concentrations in the blood, or sense of hunger and sense of thirst).

There's more than these. As research has now famously showed, even lobsters have a sense of hierarchy. Of course, Stanford's Sapolsky also made a famous presentation on the same in non-human primates (it's on Youtube, a must see). Serotonin is present in crustaceans (like the lobster) and that it is highly connected to dominance and aggressive social behaviour. When free moving lobsters are given injections of serotonin they adopt aggressive postures similar to the ones displayed by dominant animals when they approach subordinates.
