If youâre a teacher who aspires to be an assistant principal, youâre in good company. A survey by the National Association of Elementary School Principals (NAESP) found principals averaged 14 years as a teacher before moving into an administrative role.
Each glomerulus is surrounded by a heterogeneous population of juxtaglomerular neurons (that include periglomerular, short axon, and external tufted cells) and glial cells. All glomeruli are located near the surface of the olfactory bulb. The olfactory bulb also includes a portion of the anterior olfactory nucleus, the cells of which contribute fibers to the olfactory tract. They are the initial sites for synaptic processing of odor information coming from the nose.
Efferent arterioles of glomeruli in the outer cortex form the peritubular plexus which surrounds proximal and distal tubules. Efferent arterioles of glomeruli in the deeper cortex contribute to the adjacent peritubular plexus and also form the vasa recta which accompany the loop of Henle into the medulla.
