- Heart 1: Size, Shape and Location of the Heart. The heart is enclosed in a double membrane called the Pericardium or pericardial sac. It is a fiboserous sac that encloses the heart and the roots of the great vessels. Its function is to restrict excessive movemnt of the heart as a whole and to serve as a lubricated container in which the different parts of the heart can contract. The pericardium has two distinct components, a superficial fibrous pericardium and a deep serous pericardium.

Structure of Bone Tissue Spongy (cancellous) bone is lighter and less dense than compact bone. Spongy bone consists of plates (trabeculae) and bars of bone adjacent to small, irregular cavities that contain red bone marrow.The canaliculi connect to the adjacent cavities, instead of a central haversian canal, to receive their blood supply.ompact bone consists of closely packed osteons or haversian systems. The osteon consists of a central canal called the osteonic (haversian) canal, which is surrounded by concentric rings (lamellae) of matrix. Between the rings of matrix, the bone cells (osteocytes) are located in spaces called lacunae.

Heart The wall of the heart is made up of three layers: epicardium, myocardium, and endocardium. The heart is a muscular organ that pumps blood throughout the body, with a rhythm determined by a group of pacemaking cells in the sinoatrial node. These generate a current that causes contraction of the heart, traveling through the atrioventricular node and along the conduction system of the heart.

What does the periosteum contain? Structure[edit] Periosteum consists of dense irregular connective tissue. Periosteum is divided into an outer fibrous layer and inner cambium layer (or osteogenic layer). The fibrous layer contains fibroblasts, while the cambium layer contains progenitor cells that develop into osteoblasts. These osteoblasts are responsible for increasing the width of a long bone and the overall size of the other bone types.

Functions of Bones The skeletal system consists of bones, cartilage, and the membranes that line the bones. Each bone is an organ that includes nervous tissue, epithelial tissue (within the blood vessels), and connective tissue (blood, bone, cartilage, adipose, and fibrous connective tissue). Bones have many functions, including the following: Support: Bones provide a framework for the attachment of muscles and other tissues. Protection: Bones such as the skull and rib cage protect internal organs from injury. Movement: Bones enable body movements by acting as levers and points of attachment for muscles.

The Pericardium The Pericardium. 1  The pericardium (G. around the heart) is a double-walled fibroserous sac that encloses the heart (G. kardia) and the roots of the great vessels. 2  It is located in the middle mediastinum, posterior to the body of the sternum and the 2nd to 6th costal cartilages, and anterior to T5 to T8 vertebrae. The pericardium consists of two parts : (1) a strong external layer composed of tough fibrous tissue, called the fibrous pericardium, and (2) an internal double-layered sac composed of a transparent membrane called the serous pericardium.

Probiotics and Crohn's Disease: Is There Any Relief? In theory, WebMD said, the idea that probiotics may help IBD diseases like Crohn's disease and ulcerative colitis makes sense. Researchers have discovered probiotic bacteria can influence the activity of immune cells and the cells that line the intestines, the website said.ut so far, evidence-based science is lacking in definitive support for the use of probiotics in treating Crohn's disease, although according to research reported by NPR, scientists are honing in on change in gut microbiota as at least one potential cause of Crohn's disease.

Layers of the Heart Layers of the Heart. The heart consists of three layers in all. This Buzzle article explains the structure and function of each of these layers. The heart is one of the most important organs present in the human body. This organ is responsible for pumping blood to all parts of the body. Thus, it is considered as the main organ of the circulatory system. The heart is made up of specialized, smooth muscle tissue known as cardiac muscles or myocardium.

What is the Endomysium? The endomysium is sometimes referred to as the cardiac skeleton. However, this term is also sometimes used for the combination of the perimysium and the endomysium. The perimysium is a layer of connective tissue that is responsible for grouping muscle fibers together into bundles referred to as fascicles. Ad. Endomysial fibrosis is a medical condition that may affect the tissue surrounding the muscle fibers.
