1 Felon: This bacterial infection of the finger pad, caused by the same organisms that cause paronychia, is usually the result of a puncture wound. 2  The wound allows the introduction of bacteria deep into the fingertip pad. 3  Because the fingertip has multiple compartments, the infection is contained in this area.
The interlobular septae are located between secondary pulmonary lobules and are continuous with both the subpleural interstitium (peripheral connective tissue) and the peribronchovascular interstitium (axial connective tissue) as well as the more delicate intralobular septa.he interlobular septa are incomplete allowing for communication between adjacent secondary pulmonary lobules (canals of Lambert and pores of Kohn).
Posterior communicating artery. In human anatomy, the left and right posterior communicating arteries are arteries at the base of the brain that form part of the circle of Willis. Each posterior communicating artery connects the three cerebral arteries of the same side. Anteriorly, it connects to the internal carotid artery (ICA) prior to the terminal bifurcation of the ICA into the anterior cerebral artery and middle cerebral artery.
