Latin Language
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest.

Furrow
A plough or ( US) plow (both pronounced ) is a farm tool for loosening or turning the soil before sowing seed or planting. Ploughs were traditionally drawn by oxen and horses but modern ploughs are drawn by tractors. A plough may have a wooden, iron or steel frame with a blade attached to cut and loosen the soil. It has been fundamental to farming for most of history. The earliest ploughs had no wheels; such a plough was known to the Romans as an ''aratrum''. Celtic peoples first came to use wheeled ploughs in the Roman era. The prime purpose of ploughing is to turn over the uppermost soil, bringing fresh nutrients to the surface while burying weeds and crop remains to decay. Trenches cut by the plough are called furrows. In modern use, a ploughed field is normally left to dry and then harrowed before planting. Ploughing and cultivating soil evens the content of the upper layer of soil, where most plant feeder roots grow. Ploughs were initially powered by humans, but the u ...

Sulcus Primigenius
The (Latin language, Latin for "initial furrow") was the ancient Romans, ancient Roman ancient Roman religion, ritual of plowing the boundary of a new cityparticularly Colonia (Roman), formal coloniesprior to distributing its lots or erecting Ancient Roman defensive walls, its walls. The Romans considered the ritual extremely ancient, believing founding of Rome, their own founder Romulus had introduced it from the Etruscans, who had also Etruscan fortification, fortified most of Etruscan cities, their cities. The ritual had the function of rendering the course of the city wall sacrosanct but, owing to the necessity of some profane traffic such as the removal of corpses to graveyards, the city gates were left exempted from the ritual.

Gingival Sulcus
In dental anatomy, the gingival sulcus is an area of potential space between a tooth and the surrounding gingiva, gingival tissue and is lined by sulcular epithelium. The depth of the sulcus (Latin for ''groove'') is bounded by two entities: Commonly used terms of relationship and comparison in dentistry, apically by the gingival fibers of the connective tissue attachment and Commonly used terms of relationship and comparison in dentistry, coronally by the free gingival margin. A healthy sulcular depth is three millimeters or less, which is readily self-cleansable with a properly used toothbrush or the supplemental use of other oral hygiene aids. Anatomy The dentogingival tissues consist of many constituents, such as the enamel or cementum of the tooth and the connective tissue supporting epithelia like the junctional epithelium, the gingival epithelium and the sulcular epithelium. The junctional epithelium is developed during the eruption of teeth when the reduced enamel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gluteal Sulcus
The gluteal sulcus (also known as the gluteal fold, tuck, fold of the buttock, horizontal gluteal crease, or gluteal furrow) is an area of the body of humans and anthropoid apes, described by a horizontal crease formed by the inferior aspect of the buttocks and the posterior upper thigh. The gluteal sulcus is formed by the posterior horizontal skin crease of the hip joint and overlying fat and is not formed by the lower border of the gluteus maximus muscle, which crosses the fold obliquely. It is one of the major defining features of the buttocks. Children with developmental dysplasia of the hips are born with uneven gluteal folds and can be diagnosed with a physical examination and sonogram. Gluteal muscles The gluteal muscles can be classified into two main groups: The superficial gluteal muscles are responsible for extension and abduction of the hip as well as stabilizing and maintaining the balance of the pelvis during the gait cycle. Deep gluteal muscles control external ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulcus (morphology)
In biological morphology and anatomy, a sulcus (: sulci) is a furrow or fissure (Latin ''fissura'', : ''fissurae''). It may be a groove, natural division, deep furrow, elongated cleft, or tear in the surface of a limb or an organ, most notably on the surface of the brain, but also in the lungs, certain muscles (including the heart), as well as in Osteology, bones, and elsewhere. Many sulci are the product of a surface fold or junction, such as in the Gingiva, gums, where they fold around the Cementoenamel junction, neck of the tooth. In invertebrate zoology, a sulcus is a fold, groove, or boundary, especially at the edges of sclerites or between Segmentation (biology), segments. In pollen, a grain that is grooved by a sulcus is termed sulcate. Examples in anatomy Liver *Ligamentum teres hepatis fissure *Ligamentum venosum fissure *Portal fissure, found in the under-surface of the liver *Transverse fissure of liver, found in the lower surface of the liver *Umbilical fissure, ...

Sulcus (neuroanatomy)
In neuroanatomy, a sulcus (Latin: "furrow"; : sulci) is a shallow Sulcus (morphology), depression or groove in the cerebral cortex. One or more sulci surround a gyrus (pl. gyri), a ridge on the surface of the cortex, creating the characteristic folded appearance of the brain in humans and most other mammals. The larger sulci are also called Sulcus (morphology)#Brain, fissures. The cortex develops in the fetal stage of corticogenesis, preceding the cortical folding stage known as gyrification. The large fissures and main sulci are the first to develop. Mammals that have a folded cortex are known as ''gyrencephalic'', and the small-brained mammals that have a smooth cortex, such as rats and mice are termed lissencephaly, lissencephalic. Structure Sulci, the grooves, and gyri, the folds or ridges, make up the gyrification, folded surface of the cerebral cortex. Larger or deeper sulci are also often termed fissures. The folded cortex creates a larger surface area for the brain in h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glans Penis
In male human anatomy, the glans penis or penile glans, commonly referred to as the glans, (; from Latin ''glans'' meaning "acorn") is the bulbous structure at the Anatomical terms of location#Proximal and distal, distal end of the human penis that is the human male's most sensitive erogenous zone and primary anatomical source of Human sexuality, sexual pleasure. The glans penis is present in the male reproductive system, reproductive organs of humans and most other mammals where it may appear smooth, spiny, elongated or divided. It is externally lined with Mucosa, mucosal tissue, which creates a smooth texture and glossy appearance. In humans, the glans is located over the distal ends of the Corpus cavernosum penis, corpora cavernosa and is a continuation of the Corpus spongiosum (penis), corpus spongiosum of the penis. At the summit appears the urinary meatus and at the base forms the Corona of glans penis, corona glandis. An elastic band of tissue, known as the Penile frenulum ...

Colpus
Pollen is a powdery substance produced by most types of flowers of seed plants for the purpose of sexual reproduction. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells). Pollen grains have a hard coat made of sporopollenin that protects the gametophytes during the process of their movement from the stamens to the pistil of flowering plants, or from the male cone to the female cone of gymnosperms. If pollen lands on a compatible pistil or female cone, it germinates, producing a pollen tube that transfers the sperm to the ovule containing the female gametophyte. Individual pollen grains are small enough to require magnification to see detail. The study of pollen is called palynology and is highly useful in paleoecology, paleontology, archaeology, and forensics. Pollen in plants is used for transferring haploid male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a cas ...

Sulci
Sulci or Sulki (in Greek , Stephanus of Byzantium, Steph. B., Ptolemy, Ptol.; , Strabo; , Pausanias (geographer), Paus.), was one of the most considerable cities of ancient Sardinia, situated in the southwest corner of the island, on a small island, now called Sant'Antioco, Isola di Sant'Antioco, which is, however, joined to the mainland by a narrow isthmus or neck of sand. South of this isthmus, between the island and the mainland, is an extensive bay, now called the Golfo di Palmas, which was known in ancient times as the ''Sulcitanus Portus'' (Ptol.). Origins The foundation of Sulci (Punic language, Punic:) is expressly attributed to the Carthaginians (Paus. x. 17. § 9; Claudian, ''B. Gild.'' 518), and it seems to have become under that people one of the most considerable cities of Sardinia, and one of the chief seats of their power in the island. However, as noted by archaeologists the city was founded by Tyrians during the late 9th century BCE, and most of the inhabitants ...

Sulcalization
Sulcalization (from 'groove'), also called internal rounding, in phonetics, is the pronunciation of a sound, typically a sibilant consonant, such as English and , with a deep ''groove'' running along the back of the tongue that focuses the airstream on the teeth, producing a more intense sound. This is accomplished by raising the sides of the back of the tongue ("lateral contraction") and leaving a hollow along the mid-line. It is not clear if all sibilants are grooved to at least some extent. Catford (1977) observed that the degree of tongue grooving differs between places of articulation as well as between languages; however, no language is known to contrast sibilants based purely on the presence or absence of tongue grooving. English , which allows various tongue positions without apparent distinction, may also receive its characteristic quality from having a grooved tongue shape. has also been reported to show tongue grooving in English, despite being a non-sibilant fricati ...
