  • Lumbar plexor

    A nerve plexus formed by the ventral branches of the first four lumbar nerves.  

  • Enteric plexor

    One of two plexuses of nerve fibers and ganglion cells that lie in the wall of the alimentary canal. These are the myenteric (Auerbach’s) and submucosal (Meissner’s) plexuses.  

  • Dental plexor

    A network of sensory nerve fibers that are distributed to the teeth. The inferior alveolar nerve is distributed to the mandibular teeth; the anterior, middle, and posterior superior alveolar nerves contribute fibers to innervate the maxillary teeth.  

  • Choroid plexor

    A capillary network located in each of the four ventricles of the brain (two lateral, the third, and the fourth) that produces cerebrospinal fluid by filtration and secretion.  

  • Cervical plexor

    A network formed by the first four cervical spinal nerves. It innervates parts of the face, neck, shoulder, and chest, and gives rise to the phrenic nerve to the diaphragm.  

  • Celiac plexor

    A sympathetic plexus lying near the origin of the celiac artery.  

  • Cavernous plexor

    The vascular plexus of a cavernous part of the body. The following are included: Of the nose: a venous plexus in the mucosa covering the superior and middle conchae. Of the penis: a nerve plexus at the base of the penis giving rise to large and small cavernous nerves. Of the clitoris: nerve plexus at…

  • Cardiac plexor

    Plexus cardiacus; the nerve plexus at the base of the heart made up of branches of the vagus nerves and sympathetic trunks. Afferent nerves from this plexus provide the nerve supply to the heart.  

  • Brachial plexor

    A network of the anterior branches of the last four cervical and the first thoracic spinal nerves supplying the arm, forearm, and hand.  

  • Autonomic plexor

    An extensive network of nerve fibers and neuron cell bodies belonging to the sympathetic or parasympathetic nervous system.
