Pedicle Screw
Pedicle or pedicel may refer to: Human anatomy * Pedicle of vertebral arch, the segment between the transverse process and the vertebral body, and is often used as a radiographic marker and entry point in vertebroplasty and kyphoplasty procedures *Pedicle of a skin flap (medicine) * Hilum of kidney, also called the renal pedicle *Pedicel, a foot process of a renal podocyte Animal anatomy * Pedicle in brachiopods, a fleshy line used to attach and anchor brachiopods and some bivalve mollusks to a substrate *Pedicle (cervidae), the attachment point for antlers in cervids * Pedicel (antenna), the second segment of the antenna in the class Insecta, where the Johnston's organ is found * Pedicel or petiole (insect), the stem formed by a restricted abdominal segment which connects the thorax with the gaster (the remaining abdominal segments) in the suborder Apocrita * Pedicel (spider), the narrow segment connecting the cephalothorax with the abdomen Other * Pedicel (botany), the st ...

Pedicle Of Vertebral Arch
The spinal column, a defining synapomorphy shared by nearly all vertebrates,Hagfish are believed to have secondarily lost their spinal column is a moderately flexible series of vertebrae (singular vertebra), each constituting a characteristic irregular bone whose complex structure is composed primarily of bone, and secondarily of hyaline cartilage. They show variation in the proportion contributed by these two tissue types; such variations correlate on one hand with the cerebral/caudal rank (i.e., location within the backbone), and on the other with phylogenetic differences among the vertebrate taxa. The basic configuration of a vertebra varies, but the bone is its ''body'', with the central part of the body constituting the ''centrum''. The upper (closer to) and lower (further from), respectively, the cranium and its central nervous system surfaces of the vertebra body support attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
