Do lymphatic vessels have smooth muscle
http://www.lymphnotes.com/article.php/id/151/ WebSlightly larger than the typical capillary, the smooth muscle of the tunica media of the metarteriole is not continuous but forms rings of smooth muscle (sphincters) prior to the entrance to the capillaries. Each metarteriole arises from a terminal arteriole and branches to supply blood to a capillary bed that may consist of 10–100 capillaries.

Both defective SMC recruitment to collecting vessels and ectopic recruitment to lymphatic capillaries are thought to contribute to vessel failure, leading to lymphedema.
Weba series of lymph vessels lymph vessels contain clusters of lymph nodes role of lymph nodes to filter the tissues and fluids (collectively called lymph) before releasing them back into the circulation lymph vessels merge to form lymph trunks lymph trunks merge to form lymph ducts (2): - R lymphatic duct - Thoracic duct R lymphatic duct drains... WebFeb 19, 2024 · Smooth muscle cell coverage is, therefore, a marker of vessel maturation, and the reduced smooth muscle cell coverage represents the degenerative feature of collecting vessels [45, 46].
