The chest drain stitch and corner stitch are variations of the horizontal mattress. [citation needed] Other stitches or suturing techniques include: Purse-string suture, a continuous, circular inverting suture which is made to secure apposition of the edges of a surgical or traumatic wound. [13] [14] Figure-of-eight stitch; Subcuticular stitch ...
The outer root sheath corresponds with the stratum mucosum (stratum germinativum and stratum spinosum) [1] of the epidermis, and resembles it in the rounded form and soft character of its cells; at the bottom of the hair follicle these cells become continuous with those of the root of the hair.
In mammalian outer hair cells, the varying receptor potential is converted to active vibrations of the cell body. This mechanical response to electrical signals is termed somatic electromotility; [13] it drives variations in the cell's length, synchronized to the incoming sound signal, and provides mechanical amplification by feedback to the traveling wave.
Catgut suture is a type of surgical suture made of twisted strands of purified collagen taken from the small intestine of domesticated ruminants or beef tendon. It is naturally degraded by the body's own proteolytic enzymes. Full tensile strength remains for at least 7 days, and absorption is complete by 90 days. This eventual disintegration ...
Frontal hair line lowering or reconstruction (naturally high hairlines without an existing hair loss condition) If donor hair numbers from the back of the head are insufficient, it is possible to perform body hair transplantation (BHT) on appropriate candidates who have available donor hair on the chest, back, shoulders, torso and/or legs.
The site of keratinocyte stem cells remains unknown but stem cells are likely to reside in the basal layer of the epidermis and below the bulge area of hair follicles. The fibroblast involved in scarring and contraction is the myofibroblast, [30] which is a specialized contractile fibroblast. [31] These cells express α-smooth muscle actin (α ...

The hair follicle is an organ found in mammalian skin. [1] It resides in the dermal layer of the skin and is made up of 20 different cell types, each with distinct functions. The hair follicle regulates hair growth via a complex interaction between hormones, neuropeptides, and immune cells. [1]
