Achilles tendon

The Achilles tendon or heel cord, also known as the calcaneal tendon (Latin: Tendo calcaneus), is a tendon of the back of the leg, and the thickest in the human body. It serves to attach the plantaris, gastrocnemius (calf) and soleus muscles to the calcaneus (heel) bone. These muscles, acting via the tendon, cause plantar flexion of the foot at the ankle, and flexion at the knee.

The tendon can rupture and become inflamed.

"Achilles heel", referring to a vulnerability, relates to the mythical story of Achilles, who was slain during the Trojan war by a poisoned arrow to his heel.

Structure

The Achilles tendon is a tendon, meaning it connects muscle to bone, and is located at the back of the lower leg. The Achilles tendon connects the gastrocnemius and soleus muscles to the calcaneal tuberosity on the calcaneus (heel bone). The tendon begins near the middle of the calf, and receives fleshy fibers on its inner surface, almost to its lower end. Gradually thinning below, it inserts into the middle part of the back of the calcaneus bone. The tendon spreads out somewhat at its lower end, so that its narrowest part is about 4 centimetres (1.6 in) above its insertion. The tendon is covered by the fascia and the integument, and stands out prominently behind the bone; the gap is filled up with areolar and adipose tissue. A bursa lies between the tendon and the upper part of the calcaneus. It is the thickest and strongest tendon in the body. It is about 15 centimetres (6 in) long. Along the side of the muscle, and superficial to it, is the small saphenous vein. The tendon can receive a load stress 3.9 times body weight during walking and 7.7 times body weight when running.

Achilles

In Greek mythology, Achilles (/əˈkɪliːz/; Ancient Greek: Ἀχιλλεύς, Akhilleus, pronounced [akʰilːéu̯s]) was a Greek hero of the Trojan War and the central character and greatest warrior of Homer's Iliad. His mother was the nymph Thetis, and his father, Peleus, was the king of the Myrmidons.

Achilles’ most notable feat during the Trojan War was the slaying of the Trojan hero Hector outside the gates of Troy. Although the death of Achilles is not presented in the Iliad, other sources concur that he was killed near the end of the Trojan War by Paris, who shot him in the heel with an arrow. Later legends (beginning with a poem by Statius in the 1st century AD) state that Achilles was invulnerable in all of his body except for his heel. Because of his death from a small wound in the heel, the term Achilles' heel has come to mean a person's point of weakness.

Etymology

Achilles' name can be analyzed as a combination of ἄχος (akhos) "grief" and λαός (laos) "a people, tribe, nation." In other words, Achilles is an embodiment of the grief of the people, grief being a theme raised numerous times in the Iliad (frequently by Achilles). Achilles' role as the hero of grief forms an ironic juxtaposition with the conventional view of Achilles as the hero of κλέος kleos ("glory", usually glory in war).

Mystery meat navigation

Mystery meat navigation (also known as MMN) is a disparaging term coined in 1998 by Vincent Flanders, author and designer of the website Web Pages That Suck, to describe a web page where the destination of the link is not visible until the user points their cursor at it. Such interfaces lack a user-centered design, emphasizing aesthetic appearance, white space, and the concealment of relevant information over basic practicality and functionality.

The epithet "mystery meat" refers to the meat products often served in American public school cafeterias whose forms have been so thoroughly reprocessed that their exact types can no longer be identified by their appearances: like them, the methods of MMN are clear to the producer but baffling to the consumer.

Flanders originally and temporarily described the phenomenon as Saturnic navigation in reference to the Saturn Corporation, whose company website epitomized this phenomenon. Flanders writes, "The typical form of MMN is represented by menus composed of unrevealing icons that are replaced with explicative text only when the mouse cursor hovers over them".

Need To

"Need To" is a song written and recorded by the American nu metal band Korn for their self-titled debut album. It was released as the album's second single in April 1995.

Music and structure

The song features elements of an older Korn song, "Alive", which was found on their demo tape, Neidermayer's Mind. "Alive" was eventually reworked and re-recorded for the band's sixth studio album, Take a Look in the Mirror.
