Nerve

A nerve is an enclosed, cable-like bundle of axons (nerve fibers, the long and slender projections of neurons) in the peripheral nervous system. A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along each of the axons to peripheral organs.

In the central nervous system, the analogous structures are known as tracts. Neurons are sometimes called nerve cells, though this term is potentially misleading since many neurons do not form nerves, and nerves also include non-neuronal Schwann cells that coat the axons in myelin.

Each nerve is a cordlike structure that contains many axons. Within a nerve, each axon is surrounded by a layer of connective tissue called the endoneurium. The axons are bundled together into groups called fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium. Finally, the entire nerve is wrapped in a layer of connective tissue called the epineurium.

Anatomy

Nerves are categorized into three groups based on the direction that signals are conducted:

Ulu

An ulu (Inuktitut syllabics: ᐅᓗ, plural: uluit, English: "woman's knife") is an all-purpose knife traditionally used by Inuit, Yup'ik and Aleut women. It is utilized in applications as diverse as skinning and cleaning animals, cutting a child's hair, cutting food and, if necessary, trimming blocks of snow and ice used to build an igloo.

Name

In the Nunatsiavummiutut dialect, spoken in Nunatsiavut, the word is spelled uluk, and in East Greenlandic it is sakiaq or saakiq and in syllabics is ᓴᒃᑭᖅ.

Materials

Traditionally the ulu was made with a caribou antler, muskox horn or walrus ivory handle and slate cutting surface, due to the lack of metal smelting technology in the Arctic. The handle could also be carved from bone, and wood was sometimes used when it was available. In certain areas, such as Ulukhaktok Northwest Territories, copper was used for the cutting surface.

Today the ulu is still often made with a caribou antler handle but the blade is usually made of steel. The steel is quite often obtained by purchasing a hand saw or wood saw and cutting the blade to the correct shape. A hardwood called sisattaq is also used for handles. These uluit are both kept for home use and sold to others. It is also possible to purchase commercially produced uluit, sometimes made with a plastic handle and complete with a cutting board.

List of craters on Mars: O-Z

This is a list of craters on Mars. There are hundreds of thousands of impact crater on Mars, but only some of them have names. This list here contains only named Martian craters starting with the letter O – Z (see also lists for A – G and H – N).

Large Martian craters (greater than 60 km in diameter) are named after famous scientists and science fiction authors; smaller ones (less than 60 km in diameter) get their names from towns on Earth. Craters cannot be named for living people, and small crater names are not intended to be commemorative - that is, a small crater isn't actually named after a specific town on Earth, but rather its name comes at random from a pool of terrestrial place names, with some exceptions made for craters near landing sites. Latitude and longitude are given as planetographic coordinates with west longitude.
