Linea aspera From Wikipedia, the free encyclopedia. For the band, see Linea Aspera (band) . The linea aspera (Latin: rough line) is a ridge of roughened surface on the posterior surface of the femur, to which are attached muscles and intermuscular septum.Its margins diverge above and below. number of muscles attach to the linea aspera: 1  From the medial lip of the linea aspera and its prolongations above and below, the vastus medialis originates. 2  From the lateral lip and its upward prolongation, the vastus lateralis takes origin.

Ridges on Nails: What do the Vertical Lines on Nails Suggest? Lack of Moisture Can Cause Ridges on Nail or Vertical Lines on Nails: This is one important factor leading to ridges on nails. Lack of moisture causes drying of the nails, cuticle and the hands and result in the ridges.

Definitions &Translations In biometrics and forensic science, minutiae are major features of a fingerprint, using which comparisons of one print with another can be made. Minutiae include: 1  Ridge ending – the abrupt end of a ridge. 2  Ridge bifurcation – a single ridge that divides into two ridges. 3  Short ridge, or independent ridge – a ridge that commences, travels a short distance and then ends.

Abdomen The rectus abdominis muscles are long and flat. The muscle is crossed by three fibrous bands called the tendinous intersections. The rectus abdominis is enclosed in a thick sheath formed, as described above, by fibers from each of the three muscles of the lateral abdominal wall.They originate at the pubis bone, run up the abdomen on either side of the linea alba, and insert into the cartilages of the fifth, sixth, and seventh ribs.he rectus abdominis is enclosed in a thick sheath formed, as described above, by fibers from each of the three muscles of the lateral abdominal wall.

What Are Nail Ridges: Are They A Sign Of A Health Problem? Meanwhile, horizontal ridges are more likely to signal a problem. One condition, Beau's lines, is characterized by indentations across the nail bed that are a sign of disrupted growth due to illness.

Loading Next Slideshow Vertical ridges (shown here) are usually harmless and a consequence of ageing. Horizontal nail ridges running from side to side of the nail, known as Beau's lines, may be a sign of previous injury, underlying health conditions, or in rare cases, arsenic poisoning. Seek medical advice if you have concerns.

Ridge 1 Shutter ridges :- A shutter ridge is a ridge which has moved along a fault line, blocking or diverting drainage. 2  Typically, a shutter ridge creates a valley corresponding to the alignment of the fault that produces it. Dune ridges:- In areas of large-scale dune activity, certain types of dunes result in sand ridges. 2  Moraines and eskers:- Glacial activity may leave ridges in the form of moraines and eskers. 3  An arete arête is a thin ridge of rock that is formed by glacial.  erosion

- While nail ridges are not typically a serious problem, they can serve as a warning sign for a serious systemic infection or disease within the body, particularly if they develop suddenly or if the ridges form in unusual ways, such as horizontally across the nail.

Top 30 Doctor insights on: What Causes Rippled Fingernails What would cause horizontal ridges on fingernails? Beau's lines: Beau's lines, which are grooves that run horizontally across the nail plate. They usually develop when nail plate growth, which begins in the nail matrix (located under the cuticle), is temporarily disrupted.

Fingernail Ridges: A Barometer to Your Health The distinction should be made between horizontal ridges in nails and vertical ridges in nails. Vertical nail ridges are seen rather commonly and usually are not signs of serious illness. These ridges generally extend from the base of your fingernail to the tip in an orderly, regular fashion. On the other hand, horizontal nail ridges may indicate the presence of an underlying illness or medical condition, although this is not always the case. Horizontal nail ridges run from one side of the nail lengthwise across to the other side.

- Other large chewing muscles are attached on the side surfaces of the rami. The mandible (lower jawbone) consists of a horizontal horseshoe-like body with a flat ramus projecting upward at each end. The rami are divided into two processes: the mandibular condyle and a front coronoid process. The mandibular condyles unite with the mandibular tissues of the temporal bones, while the coronoid processes serve as attachments for muscles used in chewing.

Fascicular Architecture of Muscles Muscles with Parallel Fasciculi: These are muscles in which the fasciculi are parallel to the line of pull. These muscles may be: Quadrilateral, for example thyrohyoid, Strap-like, for example sternohyoid and sartorius. Strap-like with tendinous intersections, for example rectus abdominis. Fusiform, for example biceps brachii, digastric. The range of movement in such muscles is maximum.

Vertical Ridges on the Fingernails: Symptoms & Signs Aging has been described as the predominant cause of vertical ridges on the fingernails. Onychorrhexis is the medical term used to describe longitudinal ridges on the nails that often accompany brittle nails. In contrast to longitudinal ridges, Beau's lines are horizontal or transverse depressions in the nail that may be confused with nail ridging.

Fingernail Ridges: A Barometer to Your Health Vertical nail ridges, which extend from your cuticle to the tip of your nail, are fairly common and often become more numerous or prominent as you age. Vertical ridges in your nails are not a health concern.Although the exact cause of such ridging isn't known, heredity likely plays a role.he distinction should be made between horizontal ridges in nails and vertical ridges in nails. Vertical nail ridges are seen rather commonly and usually are not signs of serious illness.

- The fibers in each of these muscles run in a cross direction from one another in a way that maximizes the strength of the three muscles together (think of plywood).

Mandible At its junction with the posterior border is the angle of the mandible, which may be either inverted or everted and is marked by rough, oblique ridges on each side, for the attachment of the masseter laterally, and the Pterygoideus internus medially; the stylomandibular ligament is attached to the angle between these muscles.

- RAPMD added that those ridges (the lines you actually asked about) are referred to as philtral ridges. These form two borders of the philtrum. Above is the columella at the center base of the nose. Below is the tubercle of the lip in the center of Cupid's Bow. Pretty florid terminology for a pit that catches snot, I thought. RAPMD clarified the Cupid's Bow metaphor thusly: If you can envision the center of the lip as the bow's handle and the bottom of the philtral column as the bends in the bow above and below your hand as it holds the bow, the whole thing resembles a bow.

What Are Nail Ridges: Are They A Sign Of A Health Problem? Jessica Krant, M.D., a fellow of the American Academy of Dermatology and assistant clinical professor of dermatology at SUNY Downstate Medical Center, agrees: Lengthwise ridges, if they are evenly spaced over the whole nail, are common and harmless, and generally associated with normal aging and the nail's increasing inability to retain moisture, she says.

Muscle Anatomy & Structure Tendons connect the muscle belly to bone and they attach to the bone periosteum-more connective tissue that covers all bones. Contraction of the muscle belly pulls on the tendon and in turn, the bone it is attached to. Limb muscles (such as the biceps brachii in the upper arm) have two attachments to bone.The proximal or origin is the attachment closest to the trunk. The distal or insertion is the attachment furthest from the trunk.Trunk muscles (such as the rectus abdominus in the stomach) also have two attachments-superior (closer to the head) and inferior (further from the head). A closer look at muscle anatomy shows that each muscle belly is made up of muscle cells or fibres.imb muscles (such as the biceps brachii in the upper arm) have two attachments to bone. The proximal or origin is the attachment closest to the trunk. The distal or insertion is the attachment furthest from the trunk.
