THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Segmental arteries subsequently divide into lobar, interlobar, arcuate, and interlobular arteries before forming the afferent arterioles which feed into the glomerular capillaries.

Detailed explanation-2: -The segmental arteries have three major trunks: lateral (posterior intercostal artery or lumbar artery), middle (muscular and dorsal branches), and medial (radicular artery, radiculomedullary artery, or radiculopial artery) (Fig 1H).

Detailed explanation-3: -In its course renal artery divides into anterior and posterior division, both of these division further divide into segmental arteries that are apical, upper, middle, lower and posterior. Segmental arteries are representing an end artery and they form independent renal segments.
