What is the vein running along the centre of a leaf called?
Leaf vein diameter. In parallel veined leaves, the primary veins run parallel and equidistant to each other for most of the length of the leaf and then converge or fuse (anastomose) towards the apex. Usually many smaller minor veins interconnect these primary veins, but may terminate with very fine vein endings in the mesophyll. Minor veins are more typical of angiosperms, which may have as many as four higher orders. In contrast, leaves with reticulate venation there is a single (sometimes more) primary vein in the centre of the leaf, referred to as the midrib or costa and is continuous with
Deep vein of the thigh Deep vein of the thigh The deep vein of the thigh, (profunda femoris vein or deep femoral vein) is a large deep vein in the thigh. It receives blood from the inner thigh and proceeds superiorly and medially running alongside the profunda femoris artery to join with the femoral vein approximately at the level of the inferior-most portion of the ischial tuberosity. The deep vein of the thigh contributes the largest volume of blood to the femoral vein. The deep vein of the thigh is commonly affected by phlebitis which can be a dangerous condition in the case of a
