Skin and connective tissue diseases are a group of disorders that can be inherited or acquired, and are characterized by abnormal function in one or more elements of connective tissue including collagen, elastin or mucopolysaccharides. Tissue Membranes. According to Sandra and Matthew Blakeslee, “This map is uniquely super-developed in the human species, and it gives us a level of access to the ebb and flow of our internal sensations unequaled anywhere else in the animal kingdom.” Although each of us has the ability to feel at this level, for many it remains part of the subconscious. The work involved is multi-disciplinary involving among others physicists, organic chemists, biochemists, clinical chemists, paedia tricians, physicians, geneticists and neurologists.

It is usually located under the epithelia; which is the outer covering of the blood vessel including the esophagus, fascia between muscles, pericardial sacs, and other organs of the body. In general, “repetitive activation of a pathway strengthens those synapses, making it easier to pass information forward.” Thus, the more often we experience a type of touch, the better able our brains are to interpret that information. The types of touch we experience throughout our lives affect the architecture of our brains, which in turn affects our interpretation and response to different types of touch.

In addition, many soft tissue tumors have a pseudocapsule, which on gross examination gives the impression of complete encapsulation; these tumors should not be shelled out, because neoplastic cells are usually present in the pericapsular connective tissues. Text is a translation of 'Diseases of the Skin' which formed a part of Virchow's 'Handbuche der speciellen Pathologie und Therapie'. Cf. Author's preface to the English ed., p. [iv], vol. 1. 4. The effect of menopause on the skin and other connective tissues. The dermis is the middle layer of the three layers of skin. Skin ageing is associated with a progressive increase in extensibility and a reduction in elasticity. The lungs and arteries have a layer of elastic connective tissue that allows the stretch and recoil of these organs. Fat tissue can be found in a thin layer beneath the skin, surrounding internal organs and interwoven with other structures, such as bone marrow and breast tissue. Adipose, or fat, tissue is an example of a connective tissue that facilitates the storage, absorption and disposal of nutrient, vitamins, minerals and other substances.

There are four main types of senses, plus one anomalous sense (not skin related, called the vestibular system, which is responsible for balance and is centered in the inner ear): Information gathered through all the somatic senses is channeled through the spinal cord and is processed in parts of the brain that produce neural maps specialized for touch and movement. The unique connection the skin has with the nervous and immune systems through touch is known as the neuro-immuno-cutaneous system, which displays effects through stimulation of sweat, capillary constriction or dilation, and even change in skin tone/color. Tissues are groups of cells with a common structure (form) and function (job). Our relationship with our skin is typically superficial, but it is really one of the miracles of evolution. Unlike epithelial tissue, which has cells that are closely packed together, connective tissue typically has cells scattered throughout an extracellular matrix of fibrous proteins and glycoproteins attached to a basement membrane. They are made up of two different proteins, collagen and elastin. It comprises three distinct layers: As the sensory organ for touch, skin is one of the main gateways into the subconscious feeling intelligence we possess. Our skin is an intricate organ of consummate sophistication that has developed over millions of years. It's located between the epidermis and the subcutaneous tissue.
