Triad (anatomy)

In the histology of skeletal muscle, a triad is the structure formed by a T tubule with a sarcoplasmic reticulum (SR) known as the terminal cisterna on either side. Each skeletal muscle fiber has many thousands of triads, visible in muscle fibers that have been sectioned longitudinally. (This property holds because T tubules run perpendicular to the longitudinal axis of the muscle fiber.) In mammals, triads are typically located at the A-I junction; that is, the junction between the A and I bands of the sarcomere, which is the smallest unit of a muscle fiber.

Triads form the anatomical basis of excitation-contraction coupling, whereby a stimulus excites the muscle and causes it to contract. A stimulus, in the form of positively charged current, is transmitted from the neuromuscular junction down the length of the T tubules, activating dihydropyridine receptors (DHPRs). Their activation causes 1) a negligible influx of calcium and 2) a mechanical interaction with calcium-conducting ryanodine receptors (RyRs) on the adjacent SR membrane. Activation of RyRs causes the release of calcium from the SR, which subsequently initiates a cascade of events leading to muscle contraction. These muscle contractions are caused by calcium's bonding to troponin and unmasking the binding sites covered by the troponin-tropomyosin complex on the actin myofilament and allowing the myosin cross-bridges to connect with the actin.

Luornu Durgo

Triplicate Girl (Luornu Durgo) is a fictional character, a superhero in the 30th and 31st centuries of the DC Comics Universe and a member of the Legion of Super-Heroes.

Fictional character biography

Original continuity

Luornu Durgo, codenamed Triplicate Girl, first appeared in Action Comics #276, written by Jerry Siegel. A native of the planet Cargg, she could split into three identical bodies, as could all Carggites, due to the planet Cargg having three suns. Her costume consisted of a purple dress, orange cape and belt, and black boots.

She was the fourth hero to join the Legion of Super-Heroes, and its first non-founder member. Unlike her post-Zero Hour counterpart, Triad, she had brown eyes, not split purple/orange ones. For a long time, she had an unrequited crush on Superboy.

One of her three bodies was killed by Brainiac 5's killer creation Computo The Conqueror (a rogue computer) early on, and she was thereafter known as Duo Damsel. Her surviving two bodies continued to remember the trauma of experiencing her/their death, with the result that Computo was the one villain whom Duo Damsel was too frightened to confront.

Originally completed in 1980 and remade in 2003, Triad was designed by Evelyn Franz, who received her Master of Fine Arts in Sculpture in 1976 from Portland State University. The abstract stainless steel sculpture was funded by CETA and is installed between Southeast 37th Avenue and Southeast Ankeny in Laurelhurst Park. According to the Regional Arts & Culture Council, which administers the work, it measures 7 feet (2.1 m), 5 inches (13 cm) x 5 feet (1.5 m), 5 inches (13 cm) x 2 feet (0.61 m), 5 inches (13 cm). The Smithsonian Institution lists the measurements as approximately 50 inches (130 cm) x 8 feet (2.4 m) x 2 feet (0.61 m). The sculpture contains no inscriptions and rests on a stainless steel base which measures approximately 16 inches (41 cm) x 80 inches (200 cm) x 30 inches (76 cm). It is part of the City of Portland and Multnomah County Public Art Collection courtesy of the Regional Arts & Culture Council.
