In the chapter of the artery different parts of systemic circulation are best shown and pulmonary circulation is also well demonstrated. In this chapter many large and small arteries are described, for example, the small artery such as circumflex branch of the right coronary artery was definitely described by the author. The branches of the subclavian artery including internal thoracic and vertebral arteries are well demonstrated.
... واوریطی منقسم مي شود به سه قسم: دو از او كه آن را شرائين سباتين گويند. و سوم نيز متفرق مي شود در استخوان سينه و فقره شش گانه از رقبه و در نواحي ترقوه تا مي رسد به سر شانه. و بعد از آن از او در مي گذرد و به یدين مي رسد.»
The author also explained about the layers of the cranial meninges(piamatter and arachnoid layers) and described the cerebral arteries which are embedded within these two layers.
The superior mesenteric artery is demonstrated as a branch which is supply three parts of the small intestine (Duodenum, Jejunum and ileum). In TASHRIH-E-MANSURI these parts of gastrointestinal tract are called “AMAA-E-DEGHAGH” which means three first intestine out of six .An amazing point related with this part is an explanation about the pattern (the term JADAVEL was used)of these branches(vasa recta) which are embedded within the mesentery.
IBN-E-ILYAS in the chapter of the muscle explained about the muscle`s functions and agonist or antagonist interaction between them.
In the chapter of the nerve, the author described visual pathway greatly, and showed nearly exact neurophysiologic aspect of this pathway, which reveals amazing concept of ancient anatomist. In this part of the book the optic nerve, for example, was explained. The optic nerve origin, its anatomic relations (e.g. mammillary body),optic chisma (even mentioned as a cross-shaped structure) and finally the decussation of visual neurons at the site of optic chisma, was described.
