Thickened and/or tight filum terminale; Lipoma(s) in the spinal column; Dermal Sinus Tract (congenital deformity) Diastematomyelia (split spinal cord) [10] Tethered spinal cord is a disorder and not a mechanism so it does not spread to other people and there are no measures that can be done to prevent it beforehand.
Contraction is a key phase of wound healing with repair. If contraction continues for too long, it can lead to disfigurement and loss of function. [32] Thus there is a great interest in understanding the biology of wound contraction, which can be modelled in vitro using the collagen gel contraction assay or the dermal equivalent model. [27] [53]
Sites with periodontitis exhibit clinical signs of gingival inflammation and loss of connective tissue attachment. Connective tissue attachment loss refers to the pathological detachment of collagen fibers from cemental surface with the concomitant apical migration of the junctional or pocket epithelium onto the root surface.
Schematic of cell adhesion. Cell adhesion is the process by which cells interact and attach to neighbouring cells through specialised molecules of the cell surface. This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
Anetoderma is a benign but uncommon disorder that causes localized areas of flaccid or herniated sac-like skin due to a focal reduction of dermal elastic tissue. [3] Anetoderma is subclassified as primary anetoderma, secondary anetoderma, iatrogenic anetoderma of prematurity, congenital anetoderma, familial anetoderma, and drug-induced anetoderma.
H&E stained section of human skin. The dermoepidermal junction or dermal-epidermal junction (DEJ) is the interface between the epidermal and the dermal layers of the skin. The basal cells of the epidermis connect to the basement membrane by the anchoring filaments of hemidesmosomes; the cells of the papillary layer of the dermis are attached to the basement membrane by anchoring fibrils, which ...
The dermal papillae between the elongated rete ridges are frequently dome shaped. Necrotic keratinocytes can be observed in the basal layer of the epidermis and at the dermal-epidermal junction. Eosinophilic remnants of anucleate apoptotic basal cells may also be found in the dermis and are referred to as “colloid or civatte bodies”.
A scar (or scar tissue) is an area of fibrous tissue that replaces normal skin after an injury.Scars result from the biological process of wound repair in the skin, as well as in other organs, and tissues of the body.
