Remember that the pharynx is at a crossroads from which leads off, at the top, the passage to the mouth cavity and the passage to the nasal cavity, and below, the passage to the larynx.
The circulatory system of man and the vertebrate animals can be considered as made up of a small number of organs or subordinate systems, which are easy to recognize anatomically, and the functions of which are on the whole quite distinct.
In the numerous observations made in my laboratory upon this object, we have only once seen a combination of vessels in which there might be a direct communication between a small artery and a vein, though the two observers could not come to a final conclusion on the point.
I'm reminded of the arm, and the body, and the appendage.
Humans were built to look back; that's why we have that swivel joint in our necks
In the past few decades, there has been a revolution in how we perceive the body. What appears to be an object, a three-dimensional anatomical structure, is actually a process, a constant flow of energy and information.
I know a bit about vertebrate anatomy and I'd like to think that I'd spot if a skeleton was entirely fabricated or cobbled together from existing bits and pieces.
The digestive canal represents a tube passing through the entire organism and communicating with the external world, i.e. as it were the external surface of the body, but turned inwards and thus hidden in the organism.
Ever since then, all descendant vertebrates have had the forward end of the digestive system and the forward end of the respiratory system very much involved with each other. This manifests itself in the human body with a crossing of the two systems in the throat.
I'd like to have a neck. Everyone else has a neck, but I never got one; I don't know what happened. I'm not asking for much: just some sort of separation between my head and my body would be great.
The recurrent laryngeal nerve - which runs from the head to the voice box - goes all the way down into the chest, loops around a major artery, then goes all the way back up again. It goes right past the larynx on the way down. All a decent designer would have to do is loop it off at that point. What we're looking at is the legacy of history.
I have always had an abiding interest in that type of female anatomy.
