Langer's lines. Langer's lines, Langer lines of skin tension, or sometimes called cleavage lines, are topological lines drawn on a map of the human body. They are parallel to the natural orientation of collagen fibers in the dermis, and generally parallel to the underlying muscle fibers. Langer's lines have relevance to forensic science and the ...
v. t. e. In heraldry, the field (background) of a shield can be divided into more than one area, or subdivision, of different tinctures, usually following the lines of one of the ordinaries and carrying its name (e.g. a shield divided in the shape of a chevron is said to be parted "per chevron"). Shields may be divided this way for differencing ...
Bar (heraldry) In heraldry, a bar is an ordinary consisting of a horizontal band across the shield. If only one bar appears across the middle of the shield, it is termed a fess; if two or more appear, they can only be called bars. Calling the bar a diminutive of the fess is inaccurate, however, because two bars may each be no smaller than a ...
The lines pile up on top of each other at the band head, and may not be viewed separately. They have become unresolvable. Double head. Two bands may overlap with the head of one on top of another band or close to each other. This may make a stepped appearance. The two band heads close to each other are called a double head. Headless band
e. In heraldry, a bend is a band or strap running from the upper dexter (the bearer's right side and the viewer's left) corner of the shield to the lower sinister (the bearer's left side, and the viewer's right). Authorities differ as to how much of the field it should cover, ranging from one-fifth (if shown between other charges) up to one ...
Polycephaly. Polycephaly is the condition of having more than one head. The term is derived from the Greek stems poly (Greek: "πολύ") meaning "many" and kephalē (Greek: "κεφαλή") meaning "head". A polycephalic organism may be thought of as one being with a supernumerary body part, or as two or more beings with a shared body.
A sarcomere is defined as the segment between two neighbouring Z-lines (or Z-discs). In electron micrographs of cross-striated muscle, the Z-line (from the German "zwischen" meaning between) appears in between the I-bands as a dark line that anchors the actin myofilaments. Surrounding the Z-line is the region of the I-band (for isotropic ).
Overview. The lines in heraldry used to divide and vary fields and charges are by default straight, but may have many different shapes. Care must be taken to distinguish these types of lines from the use of lines as charges, and to distinguish these shapes from actual charges, such as "a mount [or triple mount] in base," or, particularly in German heraldry, different kinds of embattled from ...
