The dissections showed that the fascia lata (FL) attaches to the entire extent of the inferior aspect of the iliac crest. In the upper and lateral thigh, the FL receives fibrous contributions from the gluteus maximus and tensor fascia lata (TFL) to form the ITB.
Tunica media. This is the middle layer. It is made of smooth muscle and elastic fibers. It is responsible for vasodialation and vasoconstriction of the blood vessels. It is also the target tissue for Vasopressin (ADH) Hormone and plays into blood pressure. Tunica adventitia This is the most superficial of the layers.
A: Peripheral vasoconstriction is the constriction of peripheral blood vessels. When constriction of blood vessels occurs, the diameter of the blood vessel decreases, causing a decrease in blood flow. Peripheral blood vessels are those blood vessels which do not supply blood to major organs or skeletal muscles. A good example of the function of peripheral blood vessels is the blood supply to the skin. Peripheral vasoconstriction, and its opposite, vasodilation, are key to the way in which the human body regulates temperature.
