Exempel på hur du använder TRAPEZIUM i en mening

• By comparison, a quadrilateral with at least one pair of parallel sides is a trapezoid in American English or a trapezium in British English.
• one pair of parallel sides – a trapezium (τραπέζιον), divided into isosceles (equal legs) and scalene (unequal) trapezia.
• The trapezius muscle resembles a trapezium, also known as a trapezoid, or diamond-shaped quadrilateral.
• The anatomical snuff box or snuffbox or foveola radialis is a triangular deepening on the radial, dorsal aspect of the hand—at the level of the carpal bones, specifically, the scaphoid and trapezium bones forming the floor.
• The trapezium is found within the distal row of carpal bones, and is directly adjacent to the metacarpal bone of the thumb.
• The index metacarpal is the most firmly fixed, while the thumb metacarpal articulates with the trapezium and acts independently from the others.
• It is located on the radial side of the wrist, It articulates with the radius, lunate, trapezoid, trapezium, and capitate.
• Boards shown on tomb walls usually have a large trapezium appendage protruding from their edge whereas three stone boards from the archaeological record feature an animal head protrusion and two other gameboards are encircled with a goose or duck figure.
• In Euclidean geometry, an isosceles trapezoid (isosceles trapezium in British English) is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides.
• In calculus, the trapezoidal rule (also known as the trapezoid rule or trapezium rule) is a technique for numerical integration, i.
• The convex upper edge of the trapezium is decorated with a beadwork pattern and the sides are edged with sceptres.
• It originates from the flexor retinaculum of the hand, the tubercle of the scaphoid bone, and additionally sometimes from the tubercle of the trapezium.
• The superficial part is inserted with one or more tendons into the radial side of the base of the first metacarpal bone, and the deep part is variably inserted into the trapezium, the joint capsule and its ligaments, and into the belly of abductor pollicis brevis (APB) or opponens pollicis.
• The carpometacarpal joint of the thumb (pollex), also known as the first carpometacarpal joint, or the trapeziometacarpal joint (TMC) because it connects the trapezium to the first metacarpal bone, plays an irreplaceable role in the normal functioning of the thumb.
• It is connected to the trapezium of the carpus at the first carpometacarpal joint and to the proximal thumb phalanx at the first metacarpophalangeal joint.
• Central to the facilities is a well, built with well smoothed basaltic ashlars and consisting of three architectural elements: an elliptical enclosure, stairs shaped like a trapezium and a circular chamber with an ogival ceiling that contains the water.
• The midcarpal joint is formed by the scaphoid, lunate, and triquetral bones in the proximal row, and the trapezium, trapezoid, capitate, and hamate bones in the distal row.
• On the side of the radius, the flexor retinaculum is attached to the scaphoid bone, more precisely its tubercle, as well as the ridge of trapezium.
• The radial collateral ligament (external lateral ligament, radial carpal collateral ligament) extends from the tip of the styloid process of the radius and attaches to the radial side of the scaphoid (formerly navicular bone of the hand), immediately adjacent to its proximal articular surface and some fibres extend to the lateral side of the trapezium (greater multangular bone).
• The corridor zigzags slightly down the car, and the floor-plan of each roomette forms a trapezium with two right angles.
