(November 2007). The glomerulus (plural glomeruli) is a spherical structure located in the olfactory bulb of the brain where synapses form between the terminals of the olfactory nerve and the dendrites of mitral, periglomerular and tufted cells.November 2007). The glomerulus (plural glomeruli) is a spherical structure located in the olfactory bulb of the brain where synapses form between the terminals of the olfactory nerve and the dendrites of mitral, periglomerular and tufted cells.
The glomerulus is a tuft of small blood vessels called capillaries located within Bowman's capsule within the kidney. Between the capillaries and Bowman's capsule lies mesangium. glomerulus receives blood from a single artery called the afferent artery. The afferent artery is a branch of an interlobular artery in the cortex of the kidney. Contraction or relaxation of the artery can affect the pressure of capillaries in the glomerulus, and consequently the filtration of blood.
