Contrary to popular belief, the whole head is a sensory array, and there are more than 5 normal senses in total.
The temporal arteries create Visceral Sense pulsating through space.
The temple creates Traction Sense, with friction against light waves.
The hair creates a Contact (or Mirror) Sense(bald heads have a very simple Contact Sense), as double jointed brain compliment.
The sides of the head create a Turn Sense, a single joint mechanism that helps the head to turn and to balance turning of the body.
The back of the head creates a Logistical Sense, with framework helping us to scan and organise.
The crown creates a Primary Sense, which is used to orientate ourselves internally around our own mind.
And more.
