Figure 1. Forces acting on an aircraft during a level coordinated turn. Load factor is a very important structural design parameter of an aircraft, as it. indicates the amount of the load which the structure of an aircraft can bear. For. this reason, maximum load factor is a maneuvering and performance limit. The. limit load factor is the highest load factor to be expected over the lifetime of the. aircraft.
1 2. VASCULATURE OF SKIN â¢ Blood vessels of the skin are formed embyrologically by an intricate network of mesenchymal cells that come to surround arbonizing spaces. BLOOD VESSELS superficial plexus deep plexus venules ALL OF WHICH ARE CONNECTED BY COMMUNICATED BLOOD VESSELS 2. 2  3. â¢ Communicating vessels arise from and lead back to arteries and veins that lie within the septa of the subcutaneous fat.
Violet skin may result from cutaneous hemorrhage or vasculitis. Vascular lesions or tumors, such as Kaposi sarcoma and hemangiomas, can appear purple. A lilac color of the eyelids or heliotrope eruption is characteristic of dermatomyositis. Shades of blue, silver, and gray can result from deposition of drugs or metals in the skin, including minocycline, amiodarone, and silver (argyria). Ischemic skin appears purple to gray in color. Deep dermal nevi appear blue.
