The inferior cardiac nerve arises from either the inferior cervical or the first thoracic ganglion. It descends behind the subclavian artery and along the front of the trachea to join […]

The intra-articular ligament of head of rib (interarticular in older texts) is situated in the interior of the articulation of head of rib. It consists of a short band of […]

The anterior superior alveolar arteries originate from the infraorbital artery; they supply the upper incisors and canines; they also supply the mucous membrane of the maxillary sinus.

The anterior longitudinal sulcus and posterior longitudinal sulcus extend from the base of the ventricular portion to a notch the incisura apicis cordis (or notch of cardiac apex) on the […]

The left marginal artery (or obtuse marginal artery) is a branch of the circumflex artery originating at the posterior interventricular sulcus traveling along the left margin of heart towards the […]

The *spinal* somatic efferent neurons (GSE ‘somatomotor or somatic motor fibers) arise from motor neuron cell bodies in the ventral horns of the gray matter within the spinal cord. They […]

The general visceral afferent fibers (GVA) conduct sensory impulses (usually pain or reflex sensations) from the viscera glands and blood vessels to the central nervous system. They are considered to […]

The general somatic afferent fibers (GSA or somatic sensory fibers) afferent fibers arise from cells in the spinal ganglia and are found in all the spinal nerves except occasionally the […]

The atrioventricular nodal branch most frequently arises as a distal branch from the right coronary artery but occasionally the atrioventricular node receives blood from the circumflex branch of the left […]

The atrial branches of right coronary artery derive from the right coronary artery and provide part of the blood supply to the right atrium and left atrium.Although named for the […]
