21. The arteriovenous shunt in a glomus body is called the segmentum arteriale anastomosis arteriovenosae glomeriformis or Sucquet-Hoyer anastomosis. 22. The nerve fibers pick up the signals sent by glomus cells and transmit them to the central nervous system for treatment. 23. The genome of " Rhizophagus irregularis " ( formerly " Glomus intraradices " ) was recently sequenced. 24. Glomus tumors were first described by Hoyer in 1877, while the first complete clinical description was given by Masson in 1924.25. The glomus cells have a high metabolic rate and good blood perfusion and thus are sensitive to changes in arterial blood gas tension. 26. Its cells are ovoid and arranged in clusters or arches ( " glomus " is Latin for " ball " ). 27. This leads to depolarisation of the cell membrane which leads to Ca 2 + entry, excitation of glomus cells and consequent neurotransmitter release. 28. Such tumors in the middle ear go by a variety of names, but are most commonly referred to as glomus tumors or paragangliomas. 29. A few cases of malignant glomus tumors have been reported; however, they are usually only locally invasive, and metastases are exceedingly rare. 30. The glomus bodies in the skin and elsewhere are unusual in that their endothelial cells exist in multiple layers of cells called myoepithelioid cells.
