ligament

(lĭg`əmənt), strong band of white fibrous connective tissueconnective tissue,
supportive tissue widely distributed in the body, characterized by large amounts of intercellular substance and relatively few cells. The intercellular material, or matrix, is produced by the cells and gives the tissue its particular character.

 that joins bones to other bones or to cartilage in the joint areas. The bundles of collagenous fibers that form ligaments tend to be pliable but not elastic. They therefore permit freedom of movement within a certain limited range while holding the attached bones firmly in place. For example, the ligaments at the knee limit the movement of the lower leg to a certain range. Other types of ligaments form fibrous sheets that support such internal organs as the kidneys and the spleen.

Ligament

A strong, flexible connective tissue band usually found between two bony prominences. Most ligaments are composed of dense fibrous tissue formed by parallel bundles of collagen fibers. They have a shining white appearance and are pliable, strong, and noncompliant. A second kind of ligament, composed either partly or almost entirely of yellow elastic fibers, is extensible or compliant, thereby allowing the connected bones to move apart.

Ligament

 

in man, a dense band or layer of fibrous tissue that connects skeletal bones or individual organs. Ligaments usually are found near joints and perform a variety of functions, depending on the movements in the joint. Joint capsules are strengthened by reinforcing ligaments, limited in their amplitude by inhibiting ligaments, and directed in their movements by directing ligaments. In many joints, ligaments act as passive bands whose attenuation impairs static functions and alters the shape of the corresponding elements of the skeleton. The main blood vessels that nourish bone pass through some ligaments. The microscopic structure of articular ligaments consists of a variety of dense fibrous tissue whose dominant elements are bands of collagenous and elastic fibers.

The term “ligament” is often applied to anatomic formations not associated with joints, for example, the ligaments of visceral organs, which consist of fine double layers of peritoneum.

TfW says it has improved PTL on its services compared to the same period when Arriva was in charge, with a 2.1% improvement on the Wales and Borders service, and 1.6% improvement on the core valleys lines.
Over the years to 2016 little changed, but at this appointment the records show some interesting observations from the patient about the continuing benefit she experienced from PTL. She noted that they were particularly helpful at preventing headaches when she viewed text printed with certain fonts, and under fluorescent lights.
Early diagnosis of PTL is essential for timely treatment before the occurrence of widespread metastases and invasion of neighboring tissues.

It is unclear whether the above-mentioned prognostic indices and treatment regimens apply to MCL that presents as a PTL. One case report highlighted the discovery of MCL in the thyroid after a primary presentation in the gastrointestinal tract [9].
Because the PTL modules are battery powered and communicate wirelessly with a "Turbo" unit that links to the Internet, the modules can be attached to any shelf system, rack location or cart, says Blumenau.
Las medias ajustadas de PTL, PLD, PLDI y DL fueron 2870 kg, 8,53 kg, 6,61 kg y 332 d, respectivamente.
From above-stated it is following that on-line testing of the state of PTL as well as high-voltage substations which represent an integral part of the power-supply system and removal of the fault sources can be very effective.
"PTL has been a valued customer of SSS for several years, so consummating a transaction with them made strong strategic sense," said Rick Shearer, president and CEO of SSS.
PTL usually presents as a unilateral testicular mass of variable size.
Objective: To evaluate diagnostic value of vaginal pH and cervical length measurement in the second trimester of pregnancy as a preterm labor (PTL) predictor.
One of the disadvantages of neural network is the necessity of teaching it for each PTL along with considering the line and system parameters.
