Libbie Hyman
Libbie Henrietta Hyman (December 6, 1888 – August 3, 1969), was an American zoologist. She wrote numerous works on invertebrate zoology and the widely used ''A Laboratory Manual for Comparative Vertebrate Anatomy'' (1922, revised in 1942). Life Born in Des Moines, Iowa, she was a child of Jewish parents, Joseph and Sabina ( Neumann) Hyman. Her father, an emigrant from Poland, adopted the surname "Hyman" when he immigrated to the United States as a youth. Her mother was from Germany. Joseph Hyman successively owned clothing stores in Des Moines, in Sioux Falls, South Dakota, and in Fort Dodge, Iowa, but the family's resources were limited. Hyman attended public schools in Fort Dodge. At home, she was required to do much of the housework. She enjoyed reading, especially books by Charles Dickens in her father's small den, and she took a strong interest in flowers, which she learned to classify with a copy of Asa Gray's ''Elements of Botany''. She also collected butterflies and mot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triclad
Planarians (triclads) are free-living flatworms of the class Turbellaria, order Tricladida, which includes hundreds of species, found in freshwater, marine, and terrestrial habitats.pp 3., "Planarians (the popular name for the group as a whole), or triclad flatworms (the more scientific designation of the same group), are acoelomate bilaterians". Planarians are characterized by a three-branched intestine, including a single anterior and two posterior branches. Their body is populated by adult stem cells called neoblasts, which planarians use for regenerating missing body parts. Many species are able to Regeneration (biology), regenerate any missing organ, which has made planarians a popular model in research of regeneration and stem cell biology. The genome sequences of several species are available, as are tools for molecular biology analysis. The order Tricladida is split into three suborders, according to their phylogenetic relationships: Maricola, Dimarcusidae, Cavernicola ...

Dendrocoelidae
Dendrocoelidae is a family of freshwater tricladida flatworms that has a holarctic distribution. The largest freshwater triclad known belongs to this family, it's up to 40 cm in length and inhabits the Lake Baikal. Description The family Dendrocoelidae is characterized by an unusual arrangement of the muscle layers of the pharynx. While in most planarians the inner musculature of the pharynx is composed of two muscle layers, one circular and one longitudinal, in Dendrocoelidae the circular and longitudinal fibers are intermingled, forming a mixed layer. Dendrocoelidae is the sister group of Kenkiidae. Both families have an anterior adhesive organ, which is considered a synapomorphy of the group. Genera The following genera are recognised in the family Dendrocoelidae: *Genus '' Acromyadenium'' *Genus '' Alaoplana'' *Genus '' Amyadenium'' *Genus '' Anocelis'' *Genus '' Archicotylus'' *Genus '' Armilla'' *Genus ''Atria Atria may refer to: Science *Atrium (heart) ...

South Central States
The West South Central states, colloquially known as the South Central states, is a region of the United States defined by the U.S. Census Bureau as covering four states: Arkansas, Louisiana, Oklahoma, and Texas. The West South Central or South Central region is located within the Southern United States and Gulf Coast regions, bordering the Mountain states and Midwestern U.S. regions to its north and west. The Gulf of Mexico is to the south of the region. Houston is the South Central's largest city, and the Dallas–Fort Worth–Arlington metropolitan statistical area is the region's largest metropolis. A geographically diverse region, the southern portion of the states are covered by coastal plains and swamps, while the remainder is covered by forests such as the Cross Timbers, hills and mountains, and deserts near the Texas–Mexico border. With European colonization of the Americas, this region of the U.S. has been heavily influenced by the French and Spanish. With Ameri ...

CORE (research Service)
CORE (Connecting Repositories) is a service provided by the based at The Open University, United Kingdom. The goal of the project is to aggregate all open access content distributed across different systems, such as repositories and open access journals, enrich this content using text mining and data mining, and provide free access to it through a set of services. The CORE project also aims to promote open access to scholarly outputs. CORE works closely with digital libraries and institutional repositories. Service description There are existing commercial academic search systems, such as Google Scholar, which provide search and access level services, but do not support programmable machine access to the content. This is seen with the use of an API or data dumps, and limits the further reuse of the open access content (e.g., text and data mining). There are three access levels to content: * access at the granularity of papers * analytical access and granularity of colle ...

Pharynx
The pharynx (: pharynges) is the part of the throat behind the human mouth, mouth and nasal cavity, and above the esophagus and trachea (the tubes going down to the stomach and the lungs respectively). It is found in vertebrates and invertebrates, though its structure varies across species. The pharynx carries food to the esophagus and air to the larynx. The flap of cartilage called the epiglottis stops food from entering the larynx. In humans, the pharynx is part of the Digestion, digestive system and the conducting zone of the respiratory system. (The conducting zone—which also includes the nostrils of the Human nose, nose, the larynx, trachea, bronchus, bronchi, and bronchioles—filters, warms, and moistens air and conducts it into the lungs). The human pharynx is conventionally divided into three sections: the nasopharynx, oropharynx, and laryngopharynx (hypopharynx). In humans, two sets of pharyngeal muscles form the pharynx and determine the shape of its lumen (anatomy), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Specific Epithet
In Taxonomy (biology), taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammar, Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the ''generic name (biology), generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
