Radial nerve arm, and later in the anterior compartment of the arm, and continues in the posterior compartment of the forearm. The radial nerve originates from the posterior cord of the brachial plexus with root values of C5 to C8 and T1. From the brachial plexus, it travels behind the third part of the axillary artery (part of the axillary artery distal to the pectoralis minor). In the arm, it runs behind the brachial artery and then enters the lower triangular space to reach the radial sulcus of back of the humerus. It travel downwards together with profunda brachii atery, between the
Artery of the pterygoid canal small branch which anastomoses with the other tympanic arteries. It can end in the oropharynx. In this case; the artery passes backward along the pterygoid canal with the corresponding nerve. It The artery is a small, inconstant branch which passes into the pterygoid canal and anastomoses with a pterygopalatine branch of the maxillary artery. Artery of the pterygoid canal The artery of the pterygoid canal (Vidian artery) is an artery in the pterygoid canal, in the head. It usually arises from the external carotid artery, but can arise from either the internal or external carotid artery or serve as an
