Lines of cleavage are natural planes of separation in the skin that are determined by the orientation of collagen fibers. These lines are important to consider in surgery because incisions made parallel to the lines of cleavage heal better with less scarring compared to incisions made perpendicular to them.

What is the clinical significance of the lines of cleavage?
Lines of cleavage in the skin are important for surgical incisions, as making incisions parallel to the lines of cleavage can result in less scarring and improved wound healing. Surgeons often try to align incisions along these natural lines to reduce tension and minimize the risk of keloid formation.
What are parallel lines seen on either cleavage planes or crystal faces?
Parallel lines seen on cleavage planes or crystal faces are usually caused by twinning, where two crystals grow together with a specific orientation relationship. This twinning can result in repeated patterns of parallel lines that are visible on the surface of the crystal.
Does corundum have cleavage or fracture?
Corundum does not exhibit cleavage; instead, it has a conchoidal to uneven fracture. Cleavage refers to the tendency of a mineral to break along specific planes of weakness, while corundum's strong crystal structure results in a lack of such planes. Therefore, when corundum breaks, it does so irregularly rather than along defined lines.
What are the parallel lines seen on crystal faces or cleavage planes?
Parallel lines seen on crystal faces or cleavage planes are called growth striations. They are caused by variations in the crystal's growth rate or conditions during formation, resulting in alternating layers of different densities or compositions. These striations can provide valuable information about the crystal's growth history and conditions.
Does chalcopyrite have cleavage?
Chalcopyrite does not have cleavage. It typically exhibits a conchoidal fracture instead of cleavage planes.
Incisions should be made across rather than parallel to cleavage lines produced by collagen fiber bundles?
NO CLEAVAGE LINES SHOULD BE MADE PARALLEL. When and incision is made parallel to the cleavage lines, the skin gapes less and heals more readily than when the incision is made across the cleavage lines

Skin cuts parallel gape less?
cleavage lines
What layer of the dermis is responsible for cleavage lines?
epidermis
What does lines of cleavage mean?
Cleavage occurs naturally between the tissue of the two breasts. We think mostly of well-endowed females as having cleavage, but overweight boys and men can have cleavage too. The "lines of cleavage" are, as a simple description, the line between the clothing or bra and the exposed area of the breast and the "line" or separation between the breasts. So, if a woman wears an ill-fitting bra or one that is too small, the area of cleavage can be pronounced. In smaller bosoms, cleavage is less pronounced or noticeable.
What is a mineral that breaks along one or more straight lines exhibits which?
That is cleavage.
Which term describes the way a mineral breaks along certain lines of weakness?
cleavage
What are parallel lines seen on either cleavage planes or crystal faces?
Parallel lines seen on cleavage planes or crystal faces are usually caused by twinning, where two crystals grow together with a specific orientation relationship. This twinning can result in repeated patterns of parallel lines that are visible on the surface of the crystal.
What is A surgical incision parallel to the lines of cleavage?
closes and heals with relatively little scarring-gigi
Why do plastic surgeons make incisions along cleavage lines?
To heal the wound faster. If the incision is made perpendicular to the cleavage line, more fibrin will be damaged. And also to reduce scalp.
Why do some minerals break by fracturing?
Minerals can have a cleavage plane, multiple cleavage planes, or no cleavage plane. A cleavage plane is an area of weakness in the crystalline structure where the mineral is prone to splitting.
What Is the tendency of mineral to break into irregular pieces?
This is termed fracture, eg. the conchoidal fracture of obsidian. Breaking into pieces with straight lines and flat faces is called cleavage; minerals like calcite and fluorite exhibit excellent cleavage.
