-“scars are areas of ‘fibrous tissue’ (‘fibrosis’) that replace normal skin after injury-
.
(a ‘scar’ results from the biological process of ‘wound repair’ in the skin and other tissues of the body)
(thus, ‘scarring’ is a natural part of the healing process)
(with the exception of very minor ‘lesions’, every wound (e.g., after accident, disease, or surgery) results in some degree of scarring)
(an exception to this are animals with complete ‘regeneration’, which regrow tissue without ‘scar formation’)
(‘scar tissue’ is composed of the same protein (‘collagen’) as the tissue that it replaces, but the fiber composition of the protein is different; instead of a random basketweave formation of the collagen fibers found in normal tissue, in ‘fibrosis’ the collagen cross-links and forms a pronounced alignment in a single direction)
(this collagen scar tissue alignment is usually of inferior functional quality to the normal collagen randomised alignment.
(for example, scars in the skin are less resistant to ‘ultraviolet radiation’, and ‘sweat glands’ and ‘hair follicles’ do not grow back within scar tissues)
[a ‘myocardial infarction’ – (commonly known as a ‘heart attack’) – causes ‘scar formation’ in the ‘heart muscle’, which leads to loss of ‘muscular power’ + (possibly) ‘heart failure’]
.
[however, there are some tissues (e.g. ‘bone’) that can heal without any structural/functional deterioration]
