Arctic Policy Of The United States
The Arctic policy of the United States is the foreign policy of the United States in regard to the Arctic region. In addition, the United States' domestic policy toward Alaska is part of its Arctic policy. Since March 30, 1867 (when the United States purchased Alaska from the Russian Empire), the United States of America has been one of the eight Arctic nations and one of the five Arctic Ocean littoral countries. The United States has been a member of the Arctic Council since its inception in 1996 and assumed the Chairmanship (from Canada) in April 2015. 4 of the Arctic Council's 6 Permanent Participant indigenous organizations have representatives in Alaska. The United States is also an observer of the Conference of Parliamentarians of the Arctic Region. Since 1880, the global temperature has risen 0.8°C; but the temperature in the Arctic has warmed twice as much, leading to much less sea ice coverage and greater accessibility to natural resources, transport passages and fi ...

Arcus Iliopectineus
The Iliopectineal arch is a thickened band of fused iliac fascia and psoas fascia passing from the posterior aspect of the inguinal ligament anteriorly across the front of the femoral nerve to attach to the iliopubic eminence of the hip bone posteriorly. The iliopectineal arch thus forms a septum which subdivides the space deep to the inguinal ligament into a lateral muscular lacuna and a medial vascular lacuna. When a psoas minor muscle is present, its tendon of insertion blends with the iliopectineal arch It is sometimes transected in treatment of femoral nerve The femoral nerve is a nerve in the thigh that supplies skin on the upper thigh and inner leg, and the muscles that extend the knee. Structure The femoral nerve is the major nerve supplying the anterior compartment of the thigh. It is the largest ... entrapment.

Arcus Plantaris Profundus
The plantar arch is a circulatory anastomosis formed from: * deep plantar artery, from the dorsalis pedis - a.k.a. dorsal artery of the foot * lateral plantar artery The plantar arch supplies the underside, or sole, of the foot. The plantar arch runs from the 5th metatarsal and extends medially to the 1st metatarsal (of the big toe). The arch is formed when the lateral plantar artery turns medially to the interval between the bases of the first and second metatarsal bones, where it unites with the deep plantar branch of the dorsalis pedis artery In human anatomy, the dorsalis pedis artery (dorsal artery of foot) is a blood vessel of the lower limb. It arises from the anterior tibial artery, and ends at the first intermetatarsal space (as the first dorsal metatarsal artery and the deep pl ..., thus completing the plantar arch (or deep plantar arch).

Arcus Pedis Transversalis
The arches of the foot, formed by the tarsal and metatarsal bones, strengthened by ligaments and tendons, allow the foot to support the weight of the body in the erect posture with the least weight. They are categorized as longitudinal and transverse arches. Structure Longitudinal arches The longitudinal arches of the foot can be divided into medial and lateral arches. Medial arch The medial arch is higher than the lateral longitudinal arch. It is made up by the calcaneus, the talus, the navicular, the three cuneiforms (medial, intermediate, and lateral), and the first, second, and third metatarsals. Its summit is at the superior articular surface of the talus, and its two extremities or piers, on which it rests in standing, are the tuberosity on the plantar surface of the calcaneus posteriorly and the heads of the first, second, and third metatarsal bones anteriorly. The chief characteristic of this arch is its elasticity, due to its height and to the number of small joi ...

Arcus Palmaris Superficialis
The superficial palmar arch is formed predominantly by the ulnar artery, with a contribution from the superficial palmar branch of the radial artery. However, in some individuals the contribution from the radial artery might be absent, and instead anastomoses with either the princeps pollicis artery, the radialis indicis artery, or the median artery, the former two of which are branches from the radial artery. Alternative names for this arterial arch are: superficial volar arch, superficial ulnar arch, arcus palmaris superficialis, or arcus volaris superficialis.Again, ''palmar'' and ''volar'' may be used synonymously, but ''arcus volaris superficialis'' does not occur in the TA, and can therefore be considered deprecated. The arch passes across the palm in a curve (Boeckel's line) with its convexity downward, If one were to fully extend the thumb, the superficial palmar arch would lie approximately 1 cm distal from a line drawn between the first web space to the Hook of Ha ...

Arcus Palmaris Profundus
The deep palmar arch (deep volar arch) is an arterial network found in the palm. It is usually primarily formed from the terminal part of the radial artery. The ulnar artery also contributes through an anastomosis. This is in contrast to the superficial palmar arch, which is formed predominantly by the ulnar artery. Structure The deep palmar arch is usually primarily formed from the radial artery. The ulnar artery also contributes through an anastomosis. The deep palmar arch lies upon the bases of the metacarpal bones and on the interossei of the hand. It is deep to the oblique head of the adductor pollicis muscle, the flexor tendons of the fingers, and the lumbricals of the hand. Alongside of it, but running in the opposite direction—toward the radial side of the hand—is the deep branch of the ulnar nerve. The superficial palmar arch is more distally located than the deep palmar arch. If one were to fully extend the thumb and draw a line from the distal border of the thumb ...

Arcus Palatopharyngeus
The palatopharyngeal arch (pharyngopalatine arch, posterior pillar of fauces) is larger and projects farther toward the middle line than the palatoglossal arch; it runs downward, lateralward, and backward to the side of the pharynx, and is formed by the projection of the palatopharyngeal muscle, covered by mucous membrane A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is .... References External links * * * Palate Pharynx {{anatomy-stub ...

Arcus Palatoglossus
The palatoglossal arch (glossopalatine arch, anterior pillar of fauces) on either side runs downward, lateral (to the side), and forward to the side of the base of the tongue, and is formed by the projection of the glossopalatine muscle with its covering mucous membrane. It is the anterior border of the isthmus of the fauces and marks the border between the mouth and the palatopharyngeal arch. The latter marks the beginning of the pharynx The pharynx (plural: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the oesophagus and trachea (the tubes going down to the stomach and the lungs).

Arcus Palatini
The pharyngeal arches, also known as visceral arches'','' are structures seen in the embryonic development of vertebrates that are recognisable precursors for many structures. In fish, the arches are known as the branchial arches, or gill arches. In the human embryo, the arches are first seen during the fourth week of development. They appear as a series of outpouchings of mesoderm on both sides of the developing pharynx. The vasculature of the pharyngeal arches is known as the aortic arches. In fish, the branchial arches support the gills. Structure In vertebrates, the pharyngeal arches are derived from all three germ layers (the primary layers of cells that form during embryogenesis). Neural crest cells enter these arches where they contribute to features of the skull and facial skeleton such as bone and cartilage. However, the existence of pharyngeal structures before neural crest cells evolved is indicated by the existence of neural crest-independent mechanisms of pharynge ...
