oblique layer

Examples of oblique layer in the following topics:

• Muscularis

  • Each layer has different structures and functions.
  • The muscularis externa consists of an inner circular layer and a longitudinal outer muscular layer.
  • Within the muscularis externa, the circular muscle layer prevents food from traveling backward, while the longitudinal layer shortens the tract.
  • The layers are not truly longitudinal or circular, rather the layers of muscle are helical with different pitches.
  • This is the inner oblique layer, and helps churn the chyme in the stomach.

• Microscopic Anatomy of the Stomach

  • Like the other parts of the gastrointestinal tract, the stomach walls are made of a number of layers.
  • From the inside to the outside, the first main layer is the mucosa.
  • Under these muscle layers is the adventitia, layers of connective tissue continuous with the omenta.
  • The muscularis externa is made up of three layers of smooth muscle.
  • The innermost layer is obliquely-oriented: this is not seen in other parts of the digestive system.

• Animal Characterization Based on Features of Embryological Development

  • Animals develop either two or three embryonic germs layers .
  • Radially-symmetrical animals are diploblasts, developing two germ layers: an inner layer (endoderm) and an outer layer (ectoderm).
  • Diploblasts have a non-living layer between the endoderm and ectoderm.
  • Bilaterally-symmetrical animals are called triploblasts, developing three tissue layers: an inner layer (endoderm), an outer layer (ectoderm), and a middle layer (mesoderm).
  • This spiral cleavage is due to the oblique angle of the cleavage.

• The Human Eye

  • Middle Layer - composed of the choroid, ciliary body and iris.
  • Innermost Layer - the retina, which can be seen with an instrument called the ophthalmoscope.
  • The image passes through several layers of the eye, but happens in a way very similar to that of a convex lens.
  • Each eye has six muscles; lateral rectus, medial rectus, inferior rectus, superior rectus, inferior oblique, and superior oblique.
  • Layers of tissues with varying indices of refraction in the lens are shown here.

• Natural and Artificial Methods of Asexual Reproduction in Plants

  • They include grafting, cutting, layering, and micropropagation.
  • Both are cut at an oblique angle (any angle other than a right angle), placed in close contact with each other, and are then held together.
  • Layering is a method in which a stem attached to the plant is bent and covered with soil .
  • In some plants, a modified form of layering known as air layering is employed.
  • In layering, a part of the stem is buried so that it forms a new plant.

• Horizontal Asymptotes and Limits at Infinity

  • The asymptotes are computed using limits and are classified into horizontal, vertical and oblique depending on the orientation.
  • They can be computed using limits and are classified into horizontal, vertical and oblique asymptotes depending on the orientation.
  • Oblique asymptotes are diagonal lines so that the difference between the curve and the line approaches $0$ as $x$ tends toward $+ \infty$ or $- \infty$.
  • More general type of asymptotes can be defined as the oblique asymptote case.

• Anterior Muscles

  • They are continuous with the external oblique muscle of the abdomen.
  • External Oblique – The external oblique is the largest and most superficial of the flat muscles.
  • Internal Oblique – Lying deep to the external oblique, the internal oblique is smaller and thinner.
  • Its fibers run perpendicular to the external oblique, improving the strength of the abdominal wall.
  • Highlighted in orange, the external obliques lie inferior to the pectoral muscles

• Asymptotes

  • There are three kinds of asymptotes: horizontal, vertical and oblique.
  • An asymptote that is neither horizontal or vertical is an oblique (or slant) asymptote.
  • A rational function has at most one horizontal or oblique asymptote, and possibly many vertical asymptotes.
  • The graph of a function with a horizontal ($y=0$), vertical ($x=0$), and oblique asymptote (blue line).
  • Explain when the asymptote of a rational function will be horizontal, oblique, or vertical

• The Law of Sines

  • A right triangle contains a $90^{\circ}$ angle, while any other triangle is an oblique triangle.
  • Solving an oblique triangle means finding the measurements of all three angles and all three sides.
  • To solve an oblique triangle, use any pair of applicable ratios from the law of sines formula.
  • The sides of this oblique triangle are labeled a, b, and c, and the angles are labeled $\alpha$, $\beta$, and $\gamma$.

• Marine Habitats

  • Longshore currents flow parallel to the beaches, making waves break obliquely on the sand.
  • Mudflats may be viewed geologically as exposed layers of bay mud, resulting from deposition of estuarine silts, clays and marine animal detritus.
