The substantia nigra (SN) is a basal ganglia structure located in the midbrain that plays an important role in reward and movement. Substantia nigra is Latin for "black substance", reflecting the fact that parts of the substantia nigra appear darker than neighboring areas due to high levels of neuromelanin in dopaminergic neurons. Parkinson's disease is characterized by the loss of dopaminergic neurons in the substantia nigra pars compacta.
Citrus is a genus of flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as oranges, lemons, grapefruits, pomelos, and limes. The genus Citrus is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion ; and to the Middle East and the Mediterranean via the incense trade route, and onwards to Europe and the Americas.
Sycamore is a name which has been applied to several types of trees, but with somewhat similar leaf forms. The name derives from the ancient Greek συκόμορος (sūkomoros) meaning "fig-mulberry".
The mandarin orange, also known as mandarin or mandarine, is a small, rounded citrus tree fruit. Treated as a distinct species of orange, it is usually eaten plain or in fruit salads. Tangerines are a group of orange-coloured citrus fruit consisting of hybrids of mandarin orange with some pomelo contribution.
The tangerine is a type of citrus fruit that is orange in color, that is considered either a variety of Citrus reticulata, the mandarin orange, or a closely related species, under the name Citrus tangerina, or yet as a hybrid of mandarin orange varieties, with some pomelo contribution.
The indirect pathway, sometimes known as the indirect pathway of movement, is a neuronal circuit through the basal ganglia and several associated nuclei within the central nervous system (CNS) which helps to prevent unwanted muscle contractions from competing with voluntary movements. It operates in conjunction with the direct pathway.
Annona reticulata is a small deciduous or semi-evergreen tree in the plant family Annonaceae. It is best known for its fruit, called custard apple, a common name shared with fruits of several other species in the same genus: A. cherimola and A. squamosa. Other English common names include ox heart and bullock's heart. The fruit is sweet and useful in preparation of desserts, but is generally less popular for eating than that of A. cherimola.
The pars reticulata (SNpr) is a portion of the substantia nigra and is located lateral to the pars compacta. Most of the neurons that project out of the pars reticulata are inhibitory GABAergic neurons.
Rangpur, Citrus × limonia or Citrus reticulata × medica, sometimes called the rangpur lime, mandarin lime or lemandarin, is a hybrid between the mandarin orange and the citron. It is a citrus fruit with a very acidic taste and an orange peel and flesh.
The blue-streaked lory is also known as the blue-necked lory. It is a medium-sized parrot (31 cm), which is found on the Tanimbar Islands and Babar in the southern Moluccas.
Plathymenia reticulata is a species of legume native to much of eastern South America. It is placed in its own genus, Platyhymenia, although other species have previously been recognised in that genus. It grows up to 30 m (98 ft) tall, and has distinctive flattened seed pods. Its wood is rot-resistant, and is widely used as a structural timber.
Papeda or papaeda is the common name for a group of Citrus species and varieties native to tropical Asia that are hardy and slow-growing, and produce unpalatable fruit. Walter Tennyson Swingle segregated these species into a separate subgenus, Papeda, that included the Ichang lemon, yuzu, kaffir lime, kabosu, sudachi, and a number of wild and uncultivated species and hybrids. Recent genetic analysis shows the papedas to be distributed among distinct branches of the Citrus phylogenetic tree, and hence Swingle's proposed subgenus is polyphyletic and not a valid taxonomic grouping, but the term persists as a common name.
The guppy, also known as millionfish or the rainbow fish, is one of the world's most widely distributed tropical fish and one of the most popular freshwater aquarium fish species. It is a member of the family Poeciliidae and, like almost all American members of the family, is live-bearing. Guppies originate from northeast South America, but have been introduced to many environments and are now found all over the world. They are highly adaptable and thrive in many different environmental and ecological conditions. Male guppies, which are smaller than females, have ornamental caudal and dorsal fins. Wild guppies generally feed on a variety of food sources, including benthic algae and aquatic insect larvae. Guppies are used as a model organism in the fields of ecology, evolution, and behavioural studies.
Celtis reticulata, with common names including netleaf hackberry, western hackberry, Douglas hackberry, netleaf sugar hackberry, palo blanco, and acibuche, is a small- to medium-sized deciduous tree native to western North America.
Agnorhiza reticulata, known by the common name El Dorado County mule's ears, is a rare species of flowering plant found only in a small region of north-central California.
Iris reticulata, the netted iris or golden netted iris, is a species of flowering plant in the family Iridaceae. It is native from eastern Turkey to Iran, but cultivated widely in temperate regions. The reticulata group of irises is characterised by a fibrous net surrounding the bulb. They are small plants to 15 centimetres (5.9 in), with tubular, sharply-pointed, ribbed leaves, and flowers of yellow, blue or purple with an orange blaze on the falls, appearing in early spring. They are hardy, but prefer a well-drained sunny position in soil which dries out in summer; they are therefore suitable for a rock or gravel garden.
The reticulated giraffe is a species or subspecies of giraffe native to the Horn of Africa. It lives in Somalia, southern Ethiopia, and northern Kenya. There are approximately 8,500 individuals living in the wild.
Paranaleptes is a genus of longhorn beetles of the subfamily Lamiinae.
The reticulated siren, also known as the leopard siren or colloquially as the leopard eel, is a species of aquatic salamander in the family Sirenidae. The species, which is endemic to the southeastern United States, was first formally described in 2018. This cryptic salamander is known only from three localities in southern Alabama and the Florida panhandle and is one of the largest animals in the United States to be newly described in the past 100 years.
Orobanche reticulata is a species of broomrape known by the common name thistle broomrape. It is a parasitic plant whose host is normally the creeping thistle. It is native to the lowlands of Western Europe and Central Asia, but in the United Kingdom it is a rare and protected plant, growing only in Yorkshire, on grassland sites such as Quarry Moor.
