Articulations of the Vertebral Column

In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

Ultrasound imaging can be used to display the shape and movements of the tongue in real time during speech. The images can be used to determine the nature of speech sound errors. Visual feedback of the tongue can be used to facilitate improvements in speech sound production in clinical populations.

Source: Laboratory of Jonathan Flombaum—Johns Hopkins University Spoken language, a singular human achievement, relies heavily on specialized perceptual mechanisms. One important feature of language perception mechanisms is that they simultaneously rely on auditory and visual information. This makes sense, because until modern times, a person could expect that most language would be heard in face-to-face interactions. And because producing specific speech sounds requires precise articulation,...

Many important reactive minerals are formed during in situ groundwater remediation; however, conventional drill core-based methods often present challenges in collecting these minerals. This article offers techniques for utilizing the Min-Trap, an innovative passive sampling device, to effectively collect and measure reactive minerals from conventional monitoring wells.
FAQs
Bipolar electrical energy passes through the grasped tissue between the instrument’s jaws, generating heat while the jaws apply controlled pressure. That combination denatures collagen and elastin, allowing adjacent tissue layers to fuse and close a blood vessel. The tissue can then be divided, integrating hemostasis and transection within a single instrument action.
Jaw articulation changes the working angle at the instrument tip, helping the operator approach tissue that is difficult to align with a fixed jaw. This added maneuverability is especially relevant in confined operative spaces, where surrounding anatomy can limit direct access. Improved positioning may support more controlled grasping, sealing, and division during minimally invasive tumor resection.
An articulating sealer combines tissue grasping, vessel sealing, and division rather than requiring separate ligation and cutting tools for each sequence. This consolidation can streamline the operative workflow and reduce instrument exchanges. In oncology surgery, the integrated approach is relevant when researchers examine how procedural efficiency relates to surgical precision, hemostasis, tissue handling, or postoperative outcomes.
The sealing result depends on coordinated jaw positioning, tissue grasping, controlled pressure, and delivery of bipolar energy. Adequate alignment allows heat to act across the intended tissue layers, while the pressure maintains contact during fusion. These factors matter because the instrument is designed to close vessels and prepare the grasped tissue for division before transection.
A general workflow begins by positioning the articulating jaws around the selected tissue or vessel and adjusting the angle for access. The tissue is grasped while controlled pressure is applied, followed by bipolar energy delivery to denature collagen and elastin. After the layers fuse and the vessel is sealed, the tissue can be divided before continuing the resection.
Its main relevance is minimally invasive tumor resection in anatomically complex or confined operative spaces. The pivoting jaw can help investigators and surgical teams study access, precision, hemostasis, and tissue handling while reducing reliance on separate ligation and cutting instruments. These observations can also support evaluation of postoperative outcomes associated with the operative approach.
Studies can examine whether the instrument’s integrated actions affect surgical precision, hemostasis, tissue handling, procedural streamlining, and postoperative outcomes. Its use provides a practical context for comparing how tissue is grasped, sealed, and divided during tumor resection. The articulating feature also allows investigation of how improved access in confined spaces influences the conduct of minimally invasive surgery.
