The tibia /ˈtɪbiə/ (plural tibiae /ˈtɪbii/ or tibias), also known as the shinbone or shankbone, is the larger and stronger of the two bones in the leg below the knee in vertebrates (the other being the fibula), and it connects the knee with the ankle bones. The tibia is found next to the fibula on the medial side of the leg, closer to centre-line. The tibia is connected to the fibula by the interosseous membrane of leg, forming a type of joint called a syndesmosis with very little movement. The tibia is named for the Greek aulos flute, also known as a tibia. It is commonly recognized as the strongest weightbearing bone of the body.
In human anatomy the tibia is the second largest bone next to the femur. As in other vertebrates the tibia is one of two bones in the lower leg, the other being the fibula, and is a component of the knee and ankle joints.
The ossification or formation of the bone starts from three centers; one in the shaft and one in each extremity.
The tibia is categorized as a long bone and is as such composed of a diaphysis and two epiphyses. The diaphysis is the midsection of the tibia also known as shaft or body. While the epiphyses are the two rounded extremities of the bone; an upper (also known as superior or proximal) closest to the thigh and a lower (also known as inferior or distal) closest to the foot. The tibia is most contracted in the lower third and the distal extremity is smaller than the proximal.
The arthropod leg is a form of jointed appendage of arthropods, usually used for walking. Many of the terms used for arthropod leg segments (called podomeres) are of Latin origin, and may be confused with terms for bones: coxa (meaning hip, plural coxae), trochanter (compare trochanter), femur (plural femora), tibia (plural tibiae), tarsus (plural tarsi), ischium (plural ischia), metatarsus, carpus, dactylus (meaning finger), patella (plural patellae).
Homologies of leg segments between groups are difficult to prove and are the source of much argument. Some authors posit up to eleven segments per leg for the most recent common ancestor of extant arthropods but modern arthropods have eight or fewer. It has been argued that the ancestral leg need not have been so complex, and that other events, such as successive loss of function of a Hox-gene, could result in parallel gains of leg segments.
The appendages of arthropods may be either biramous or uniramous. A uniramous limb comprises a single series of segments attached end-to-end. A biramous limb, however, branches into two, and each branch consists of a series of segments attached end-to-end.
A tibia is a sort of organ pipe that is most characteristic of a theatre organ.
Tibia pipes are generally made of wood, stopped, from 16' (Occasionally 32') with the top octave pipes (above 1/2', or 6" made of metal, stopped, and pipes from 1/4', 3" made of metal and open.
The mouth is cut very high, and the pipes have little harmonic development - the sound approaches that of a sine wave.
There is usually a tremulant on the wind for Tibia pipes - the increase and decrease of wind pressure gives "life" to the sound.
There's war in the heavens
Rebellion on high
the son of the morning
Descends from a black sky
Severed and broken
His wings burned to dust
His coverings of diamonds and gold
In a moment in time dissolve to rust
Thunder and lightning
Shatter the night
The dragon of darkness
Appears cursed by the keeper of the light
The dark is chosen
The scroll has been sealed
Hidden in verses of prophets
His face is revealed
Songs of glory
Shout across the land
I can take you there
Child of mine, take my hand
Down through the ages
The story's been told
The daughter of wisdom
Beguiled by the serpent of old
Born into sin in a valley of thorns
Torn from enchantment and
Tossed into the eye of the storm
Heaven's garden
Made by God for man
This is paradise
Child of mine, take my hand
Glory to glory
Sin after sin
The rider of death
Pushes on to the place where
The battle must begin
Songs of glory
Shout across the land
This is paradise
Won't you take my hand
Heaven's garden
Made by God for man
This is paradise
Child of mine, take my hand
Oh, take my hand
