Haversian canals (also called central canals) run longitudinally through the bone and contain blood vessels and nerves which supply the bone.
Business casual: Generally means khaki pants, a plain polo shirt or a long-sleeved casual button-down oxford shirt, a V-neck sweater, sometimes a sports coat or blazer, and brown leather shoes. Loafers are a good choice, and you should wear socks.
Weâve already been over this before. The nice part of a business casual outfit is youâre afforded an extra bit of leeway with shoes â you donât have to stick with just a black or brown cap-toe. Try a burgundy loafer, a shell cordovan plain-toe blucher, or a tan semi-brogue. Sneakers are always unacceptable.
