We present a novel surgical procedure to implant electrodes in Manduca sexta during its early metamorphic stages. This technique allows mechanically stable and electrically reliable coupling with the neuromuscular tissue to study flight neurophysiology dynamics. We also present a novel magnetic levitation platform for tethered studies of insect yaw.

Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT The purpose of peripheral intravenous catheter (PIV) insertion is to infuse medications, perform intravenous (IV) fluid therapy, or inject radioactive tracers for special examination procedures. Placing a PIV is an invasive procedure and requires the use of an aseptic, no-touch technique. Common IV venipuncture sites are the arms and hands in adults and the feet in children. According to...

We describe a method to directly measure muscle force, muscle power, contractile kinetics and fatigability of isolated skeletal muscles in an in vitro system using field stimulation. Valuable information on Ca2+ handling properties and contractile machinery of the muscle can be obtained using different stimulating protocols.

Safe reliable placement of a central venous catheter (CVC) in...
FAQs
The insertion’s position helps determine how a muscle’s shortening is expressed as joint motion. When the muscle contracts, force is applied through the attachment and the insertion is pulled toward the origin, so the resulting movement depends on which joint or joints the attachment relates to. Mapping this relationship helps explain muscle action and joint mechanics.
Muscle Insertion is not interpreted as a completely fixed point in every analysis. The attachment may shift relative to the origin as body position changes, and the movement being examined can alter how the relationship is described. Accounting for these conditions prevents an analysis from treating muscle action as identical across all postures or movements.
A tendon or aponeurosis provides the connection between the contracting muscle and its attachment site when that form of attachment is present. This connection is important because it links muscle shortening to movement at a bone or another structure. Distinguishing the attachment tissue helps anatomical descriptions explain how force is transmitted into the movement system.
Comparing insertion with origin clarifies the direction of muscular action. The origin serves as the reference toward which the insertion is pulled during skeletal muscle contraction, while analyzing the insertion identifies the structure whose position contributes to movement. This comparison is useful when explaining why a particular muscle affects one or more joints and how coordinated movement is organized.
To identify a Muscle Insertion in a biology study, locate where the muscle connects to a bone or other structure, note whether a tendon or aponeurosis forms the attachment, and relate that site to nearby joints. Then analyze the contraction-related pull toward the origin and consider body position and the movement under study.
Information about insertions supports several forms of musculoskeletal investigation. In anatomy and biomechanics, it helps clarify muscle actions and joint mechanics; in injury and rehabilitation studies, it provides relevant attachment information; and in surgical planning and comparative anatomy, it helps researchers examine structural relationships and differences in movement.
