tunic

Examples of tunic in the following topics:

• Chordates and the Evolution of Vertebrates

  • Members of Urochordata are also known as tunicates .
  • The name tunicate derives from the cellulose-like carbohydrate material, called the tunic, which covers the outer body of tunicates.
  • Most tunicates are hermaphrodites.
  • The primary foods of tunicates are plankton and detritus.
  • Like tunicates, they are suspension feeders .

• Phylum Chordata

  • In addition to containing vertebrate classes, the phylum Chordata contains two clades of invertebrates: Urochordata (tunicates) and Cephalochordata (lancelets).
  • For example, tunicate larvae have both a notochord and a nerve cord which are lost in adulthood .
  • Most tunicates live on the ocean floor and are suspension feeders.
  • While tunicates are invertebrates and may seem very different from the more familiar members of Chordata, the tunicate larva possesses both a notochord and a dorsal nerve cord, although both are lost in adulthood.

• Textiles of the Inca

  • Clothing consisted of the Chimú loincloth, sleeveless shirts, small ponchos, and tunics.
  • For example, Inca officials wore stylized tunics decorated with certain motifs, and soldiers of the Inca army had specific uniforms.
  • Inca officials wore stylized tunics decorated with certain motifs, while soldiers of the Inca army had specific uniforms.

• Romanesque Sculpture: Majestat Batlló

  • It is a triumphant Christ wearing a colobium, or a long, sleeveless tunic.
  • A thin belt with an elaborate interlace knot pulls the tunic in above Christ's hips, making the fabric above it swell out slightly and curving the path of its flat, wide vertical folds.
  • The frontal geometric composition of the tunic decorated in circles and floral motifs is reminiscent of the refined Byzantine and Hispano-Moorish fabrics held in such high esteem in the Christian West during this time.
  • The tunic also has an analogy with an Islamic motif abacus of the cloister of the abbey of Saint-Pierre de Moissac, which seems to prove the spread during the Romanesque period.

• Arteries, Veins, and Capillaries

  • There are three distinct layers, or tunics, that form the walls of blood vessels .
  • This tunic is continuous with the endocardium of the heart.
  • Unlike veins and arteries, capillaries have only one tunic; this single layer of cells is the location of diffusion of oxygen and carbon dioxide between the endothelial cells and red blood cells, as well as the exchange site via endocytosis and exocytosis.
  • Veins and arteries both have two further tunics that surround the endothelium: the middle, tunica media is composed of smooth muscle, while the outer tunica externa is connective tissue (collagen and elastic fibers).
  • Capillaries consist of a single layer of epithelial cells, the endothelium tunic (tunica intima).

• The Evolution of Craniata and Vertebrata

  • According to these genomic analyses, vertebrates appear to be more closely related to the lancelets (cephalochordates) than to the tunicates (urochordates).
  • A comparison of the genomes of a lancelet, tunicate, lamprey, fish, chicken, and human confirmed that two whole-genome duplications occurred in the early history of the Vertebrata subphylum.

• The Inca People

  • The brightly colored patterns on a wool tunic represented various positions and achievements.
  • The complex patterns woven into most Inca textiles and made into tunics, like this one, denoted a person's position in society.

• Asexual Reproduction in Plants

  • Bulbs, such as a scaly bulb in lilies and a tunicate bulb in daffodils, are other common examples of this type of reproduction.

• Muscularis

  • The gastrointestinal (GI) tract is composed of four layers of tissue, known as tunics.

• Tiwanaku and Wari

  • Tapestries and tunics provide examples of textiles found at Tiwanaku.
