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.
Next, you need a slip-on business casual shoe, like a loafer. Youâll wear this shoe most days if you work in a dress down environment. You can wear it with khakis or jeans. Wear your loafers, with or without socks, with a slim (not skinny) pant. The blazer is optional.
