Source: Richard Glickman-Simon, MD, Assistant Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine, MA This video describes the examination of the ear, beginning with a review of its surface and interior anatomy (Figure 1). The cartilaginous auricle consists of the helix, antihelix, earlobe, and tragus. The mastoid process is positioned just behind the earlobe. The slightly curving auditory canal ends at the tympanic membrane, which transmits sound...

Techniques are described to immunostain phospho-epitopes in whole zebrafish embryos and then conduct two-color fluorescent confocal localization in cellular structures as small as primary cilia. The techniques for fixing and imaging can define the location and kinetics of the appearance or activation of specific proteins.

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Antibody specificity determines whether the detected signal corresponds to the intended protein or cellular feature. The primary antibody binds the target molecule, and the detection system makes that binding visible within the tissue. Consequently, the observed pattern can be interpreted as evidence of where the target occurs, supporting analysis of cellular differentiation and tissue organization during inner-ear development.
The primary antibody provides molecular recognition by binding a particular antigen in the tissue. A separate fluorescently or enzymatically labeled detection system then reveals where that binding has occurred. Keeping these roles conceptually distinct helps investigators connect a visible signal with the distribution of a specific molecule rather than treating the label itself as the biological target.
A signal’s location shows which cells or structures contain the target, while its appearance across developmental time indicates when that feature emerges or changes. Examining both dimensions can reveal relationships among cell differentiation, tissue organization, and developmental signaling. This makes staining patterns more informative than a single observation from one developmental stage.
The method can be applied to fixed tissue sections or whole-mount preparations. Sections provide views through preserved tissue regions, whereas whole mounts maintain a broader spatial arrangement of the developing inner ear for visualization. Selecting between these formats depends on the tissue organization and spatial pattern that the investigation needs to examine.
By using antibodies directed against different target molecules, investigators can visualize patterns associated with sensory hair cells, supporting cells, neurons, and other tissue components. Comparing the locations of these signals helps map how distinct populations emerge and become organized. The resulting images provide spatial evidence for developmental changes in cell identity and arrangement.
Researchers can compare immunostaining patterns between developing inner ears under different genetic or experimental conditions. Changes in signal location or timing may indicate altered cell differentiation, tissue organization, developmental signaling, or the development of particular inner-ear components. This comparison links a perturbation with observable changes in the spatial and temporal progression of development.
