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 ...
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.
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.
The hair cells near the helicotrema are at higher risk of acoustic trauma than those in most other parts of the cochlea. [5] It is also important during ear surgery. [6] When pressure is placed on the perilymph in the cochlea, it reduces pressure and prevents damage to the organ of Corti.
The inner root sheath or internal root sheath of the hair follicle is located between the outer root sheath and the hair shaft. [1] It is made of three layers: Henle's layer, Huxley's layer, and the cuticle. [2] The inner root sheaf serves to protect growing hair. [3]
Hair cells and supporting cells are both located in the cochlea inside the inner ear. [1] [2] In mammals, hair cells are located in the Organ of Corti and convert energy from sound waves and physical movement into electrical signals. [2] This is accomplished through integrating neurons with hair cells that transmit signals to the auditory nerve ...
These are modified keratins containing large amounts of the amino acid cysteine, which facilitates chemical cross-linking of these proteins to form the tough material from which hair and nail is composed. These cells give rise to non-hair non-keratinized IRSC (inner root sheath cell) as well.
Movement of organelles in Tradescantia stamen hair cells. Cytoplasmic streaming, also known as cyclosis, is the active movement of a cell's contents along the components of the cytoskeleton. While mainly seen in plants, all cell types use this process for transportation of waste, nutrients, and organelles to other parts of the cell.
