The vascular bundles are closed type as the cambium is absent. Further, the vascular bundles are scattered throughout the ground tissue. The vascular bundle contains Xylem (present toward the inner surface) and Phloem (present toward the outer surface).

The nasal septum is made up of bone and cartilage. The cartilage portion of the nasal septum is the hyaline type of cartilage. Apart from the nasal septum, hyaline cartilage is also present in the larynx, trachea, …

Mesangial cells are located in the glomerular capillaries of the renal corpuscle in the kidney. They are derived from smooth muscles and phagocytize components of the glomerular basal lamina. Apart from phagocytic functions, they also provide structural support to the glomerular capillaries and regulate glomerular filtration.
