1 hibernating myocardium typically represents a chronic process whereas stunned myocardium is typically related to an acute infarction or ischaemic insult resulting in altered wall motion. 2  repetitive stunning may evolve into hibernating myocardium. differentiation from stunned myocardium can be difficult, but can sometimes be made on the basis of maintained, or nearly maintained, perfusion with a wall motion abnormality (hibernating myocardium will have abnormal perfusion and a wall motion abnormality).
The basement membrane is a thin, fibrous, extracellular matrix of tissue that separates the epithelium (skin, respiratory tract, gastrointestinal tract, etc), mesothelium (pleural cavity, peritoneal cavity, pericardial cavity, etc) and endothelium (blood vessels, lymph vessels, etc) from underlying connective tissue.he two layers together are collectively referred to as the basement membrane. The basal lamina layer can further be divided into two layers. The clear layer closer to the epithelium is called the lamina lucida, while the dense layer closer to the connective tissue is called the lamina densa.
Connective tissue (CT) is one of the four types of biological tissue that support, connect, or separate different types of tissues and organs in the body.The other three types are epithelial, muscle, and nervous tissue.Connective tissue is found in between other tissues everywhere in the body, including the nervous system. In the central nervous system the outer membranes, the meninges, that cover the brain and spinal cord are composed of connective tissue.onnective tissue (CT) is one of the four types of biological tissue that support, connect, or separate different types of tissues and organs in the body.
