The accompanying video describes a procedure for percutaneous placement of the WATCHMAN Left Atrial Appendage (LAA) Device. The WATCHMAN is a nitinol device designed to be permanently implanted at, or slightly distal to, the opening of the left atrial appendage (LAA) to trap blood clots before they exit the LAA, preventing thromboembolic stroke.

Archaeal surface appendages are highly specialized structures essential for environmental adaptation, encompassing roles in adhesion, biofilm formation, and motility. Among these appendages, pili and archaella stand out for their distinct morphologies and functionalities, enabling archaea to thrive in diverse and often extreme environments.Pili: Adhesion and Biofilm FormationPili are filamentous structures assembled from pilin protein subunits, primarily contributing to adhesion and biofilm...

In order to observe ultrastructure of insect sensilla, scanning and transmission electron microscopy (SEM and TEM, respectively) sample preparation protocol were presented in the study. Tween 20 was added into the fixative to avoid sample deformation in SEM. Fluorescence microscopy was helpful for improving slicing accuracy in TEM.

Using two methods to estimate gene expression in the major gustatory appendages of Aedes aegypti, we have identified the set of genes putatively underlying the neuronal responses to bitter and repulsive compounds, as determined by electrophysiological examination.
FAQs
The curved tips concentrate contact with a prey item, particle, or surface, allowing the appendage to engage it rather than relying on broad contact. Muscles and associated tissues position or move the structures, so their effectiveness depends on coordinated motion as well as shape. Examining tip curvature alongside movement helps connect anatomy with feeding, attachment, or environmental interaction.
The appendages cannot be understood from their hooks alone. Associated tissues and muscles determine how the structures are positioned, moved, and applied against a target. This context helps distinguish a feature adapted for active grasping from one used mainly for anchoring. In microscopic specimens, preserved attachments may therefore provide functional evidence that the outline of the appendage does not show by itself.
Researchers can compare the arrangement of paired structures, the curvature and shape of their tips, and their relationship to surrounding tissues. These features indicate whether appendages share a similar organization or represent different specializations for feeding, attachment, or environmental interaction. Such comparisons support functional interpretation and can also reveal similarities and differences among animal groups.
Variation in form and arrangement can reflect adaptation to different functional demands, such as engaging prey or maintaining contact with a surface. At the same time, recurring structural patterns may help researchers compare related animal groups. When appendages occur in microscopic specimens or fossils, their preserved morphology can connect anatomical evidence with hypotheses about function and evolutionary relationships.
Investigation begins by documenting the appendages' paired arrangement, curved tips, and relationships with nearby tissues. Researchers then evaluate how muscles or associated structures could position or move them, and compare the observations across specimens or animal groups. In microscopic or fossil material, careful examination of preserved form is especially important because functional conclusions must be based on anatomical evidence.
Their morphology can help identify species and infer how an organism interacted with its surroundings. Tip shape and arrangement may indicate whether the structures supported feeding, attachment, or another form of contact, while associated tissues add evidence about movement. These observations make Hami appendages useful for linking anatomical form with organismal function rather than treating them as isolated traits.
Preserved specimens can retain the shape, pairing, and arrangement of these structures even when direct observation of living behavior is unavailable. Microscopic material may show fine anatomical relationships, whereas fossils can extend comparisons beyond living organisms. Researchers use that preserved evidence to assess possible function, distinguish organisms, and investigate structural continuity or change among animal groups.
The structures provide a connection between several biological questions: how an organism feeds or attaches, how specialized anatomy supports interaction with the environment, and how related forms can be distinguished. Their study combines functional analysis, species identification, comparative anatomy, and evolutionary interpretation. This broader context makes the appendages informative evidence for understanding organismal biology across different animal groups.
