Endothelium, which is the innermost layer of all blood vessels.
Blood vessels are surrounded by very small circular muscles which contract and relax to allow blood vessels to constrict and dilate. The vessels also contain elastin which allows them to stretch.
Tunica Media
tunica adventitia
the middle layer, called the tunica media
The Epidermis is the outermost, Avascularized (lacks blood vessels), protective layer. Its composed of Keratinized Stratified Squamous Epithelial Cells.
connectiveThe outer layer of a blood vessel (artery or vein) is called the tunica externa or tunica adventitia.See http://training.seer.cancer.gov/module_anatomy/unit7_3_cardvasc_blood1_classification.htmlpericardium is the layer of the blood vessel that is made of tough connective tissue.
it is called Endothelium (endothelial layer) composed of simple squamous epithelium forming a countinuous barrier.
The epineurium is the outermost layer of connective tissue surrounding a peripheral nerve. It includes the blood vessels supplying the nerve.
Venules are small blood vessels with three basic layers. These layers are an inner membrane called an endothelium, a middle layer of muscle tissue, and the outer layer, which is made of fibrous connective tissue.

On the outer surface of the compact bone is a layer of connective tissue.
A thin, single-celled, layer of squamous endothelial tissue overlapped inside by an interlacing network of other cell tissue. There are two more layers on top of this inner layer.
