plate

 [plāt]
1. a flat stratum or layer.
2. dental plate; sometimes, by extension, incorrectly used to designate a complete denture.
3. a flat vessel, usually a petri dish, containing sterile solid medium for the culture of microorganisms.
4. to prepare a culture medium in a petri dish, or to inoculate such a medium with a bacterial culture.
axial plate primitive streak.
bite plate biteplate.
cortical plate a layer of compact bone overlying the spongiosa of the alveolar process on the vestibular and oral aspects of the mandible and maxilla.
deck plate roof plate.
dental plate a plate of acrylic resin, metal, or other material that is fitted to the shape of the mouth, and serves for the support of artificial teeth.
dorsal plate roof plate.
end plate see end plate.
epiphyseal plate the thin plate of cartilage between the epiphysis and the shaft of a long bone; it is the site of growth in length and is obliterated by epiphyseal closure.
equatorial plate the collection of chromosomes at the equator of the spindle in mitosis.
floor plate the unpaired ventral longitudinal zone of the neural tube; called also ventral plate.
foot plate footplate.
force plate force platform.
medullary plate neural plate.
muscle plate myotome (def. 2).
neural plate a thickened band of ectoderm in the midbody region of the developing embryo, which develops into the neural tube; called also medullary plate.
roof plate the unpaired dorsal longitudinal zone of the neural tube; called also dorsal plate and deck plate.
tarsal plate tarsus (def. 2).
ventral plate floor plate.

force plate

A flat, floor-mounted instrument, similar to a scale, for determining weight-bearing loads and biomechanical forces placed on the foot during walking or running. It is used to detect subtle body movements in order to identify postural deficits, or to develop (in athletes or people with balance disorders) more fluid and safer coordination and locomotion.

Increased lower limb flexion and joint excursion during landing are thought to reduce vertical ground reaction forces (vGRF).

In this case, the torques of both the hip motor and knee motor increase dramatically because of the ground reaction force.
[37] similarly evaluated the unweighting effects of the AlterG[R] finding a linear relationship between programmed unweighting parameters and ground reaction forces reporting an approximate reduction in maximum force of 8% and 20% at 80% and 60% body weight at a self-selected speed with other reports of a reduction in force during running [17] and walking [18] while maintaining similar metabolic consumption.
Data analysis included ground reaction force, power, and jump height.
Similarly, flexion torque at the knee joint is necessary to endure the vertical ground reaction force. Due to the two-jointed muscle, HA, a large flexion torque was also produced at the knee joint, and it was released by the knee extensor, VA.
where F = [[[f.sup.T.sub.1], [f.sup.T.sub.2].sup.T] is a vector of the ground reaction forces acting on the left foot and the right foot.

The plantar load can be considered as equal to the sum of ground reaction forces (GRFs) which are acting between the foot and ground during stance phase.
