Picture of the Arteries Each artery is a muscular tube lined by smooth tissue and has three layers: 1  The intima, the inner layer lined by a smooth tissue called endothelium. 2  The media, a layer of muscle that lets arteries handle the high pressures from the heart. 3  The adventitia, connective tissue anchoring arteries to nearby tissues.

Receptacle (botany) Receptacle (botany) In botany, the receptacle or torus (an older term is thalamus, as in Thalamiflorae) is the thickened part of a stem (pedicel) from which the flower organs grow. In some accessory fruits, for example the pome and strawberry, the receptacle gives rise to the edible part of the fruit. The fruit of Rubus species is a cluster of drupelets on top of a conical receptacle. When a raspberry is picked, the receptacle separates from the fruit, but in blackberries, it remains attached to the fruit.

The Cardiovascular System VESSELS. Blood vessels are usually composed of three layers: the tunica intima, tunica media, and tunica adventitia. The tunica intima consists of a layer of endothelial cells lining the lumen of the vessel, as well as a subendothelial layer made up of mostly loose connective tissue.

- Veins tend often to look collapsed or flattened under the same circumstances. In addition, the tunica media of veins is much thinner than in arteries, and the adventitia is the thickest layer. Identify the three layers of both arteries and veins and note the differences in thickness. Slide #174 In very large vessels, the adventitial layer (outer layer) will contain blood vessels (vasa vasorum) that supply the vessel wall.

- The part that runs up along the right wail of the superior vena cava is separated from adventitia by a great amount of fatty tissue and from the internal side of this vena by transverse bundles of ascending layers of the right auricle from 0.

Tunica media The tunica media (New Latin middle coat), or media for short, is the middle tunica (layer) of an artery or vein.It lies between the tunica intima on the inside and the tunica externa on the outside.unica media is made up of smooth muscle cells and elastic tissue. It lies between the tunica intima on the inside and the tunica externa on the outside.

Histology of blood vessels The walls of arteries and veins are composed of endothelial cells, smooth muscle cells and extracellular matrix (including collagen and elastin). These are arranged into three concentric layers: intima, media and adventitia. The intima is the inner layer abutting the vessel lumen.

What is a Ligamentum Teres? The ligamentum teres is a type of round ligament found in specific areas of the body. Some of these area include the uterus and the liver. The ligamentum teres can also be found in the elbow and the femur. The precise role of the round ligament is dependent upon the area of the body in which it resides.

- The media, a layer of muscle that lets arteries handle the high pressures from the heart; The adventitia, connective tissue anchoring arteries to nearby tissues; The largest artery is the aorta, the main high-pressure pipeline connected to the heart's left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries' smaller branches are called arterioles and capillaries.

Epiphysis This article is about the rounded end of a bone. For information on the endocrine gland also referred to as epiphysis, see epiphysis cerebri. The epiphysis (/ɛˈpɪfɨsɨs/) is the rounded end of a long bone, at its joint with adjacent bone(s).Between the epiphysis and diaphysis (the long midsection of the long bone) lies the metaphysis, including the epiphyseal plate (growth plate).At the joint, the epiphysis is covered with articular cartilage; below that covering is a zone similar to the epiphyseal plate, known as subchondral bone.his article is about the rounded end of a bone.
