The American bullfrog's (Rana catesbeiana) sacculus permits direct examination of hair-cell physiology. Here the dissection and preparation of the bullfrog's sacculus for biophysical studies is described. We show representative experiments from these hair cells, including the calculation of a bundle's force-displacement relation and measurement of its unforced motion.

Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here. Hair cells are named after...

Current methods of analyzing patients’ adherence to complex drug resistant-tuberculosis (DR-TB) regimens can be inaccurate and resource-intensive. Our method analyzes hair, an easily collected and stored matrix, for concentrations of 11 DR-TB medications. Using LC-MS/MS, we can determine sub-nanogram drug levels that can be utilized to better understand drug adherence.

Accessory Structures of the Skin: Hair and Hair Follicles

Hair and hair follicles are integral components of the integumentary system. Hair is a filamentous structure composed mainly of a protein called keratin. It is found on the surface of the skin throughout the body, except for areas such as the palms of the hands and soles of the feet. Hair is a keratinous filament growing out of the epidermis. It is primarily made of dead, keratinized cells. Hair strands originate at the epidermal penetration called the hair follicle. The hair shaft is the part...
FAQs
Local sensitivity helps determine how strongly a removal procedure may stimulate cutaneous sensory pathways. Areas with greater sensitivity may require a more cautious choice or adjustment of the method, because mechanical input can produce stronger nociceptive responses. Recording this factor before treatment helps distinguish effects of the removal procedure from differences in baseline skin responsiveness.
Hair and skin condition influence procedural consistency as well as sensory response. Assessing them beforehand can reveal whether the treatment area is suitable for the selected approach and whether local factors might alter stimulation. This assessment supports more controlled comparisons, since differences in hair or skin state could otherwise be mistaken for differences in discomfort or neural response.
During removal, mechanical stimulation of the skin can activate nociceptors and contribute to discomfort. Preparation therefore has a mechanistic role: cleansing, drying, and method adjustment help standardize the physical conditions under which stimulation occurs. In neuroscience-oriented work, controlling those conditions makes observed pain or sensation responses easier to relate to the stimulus rather than to avoidable variation.
Begin by evaluating the hair and skin condition, then identify local sensitivity relevant to the planned approach. Cleanse the treatment area and allow it to dry before removal. Finally, select or adjust the method in light of those observations. Keeping this sequence consistent improves procedural control and creates a clearer basis for comparing sensory outcomes.
Consistent preparation reduces variation before the removal stimulus is delivered. Using the same assessment and cleansing sequence, while documenting skin condition and local sensitivity, gives each method a more comparable starting point. This is especially useful when researchers or clinicians examine discomfort, tactile responses, or pain-related outcomes across procedures, because baseline differences can influence interpretation.
Adjustment becomes particularly important when the treatment area differs in local sensitivity or when hair and skin condition may change how the procedure stimulates the skin. The aim is not simply to remove hair, but to account for factors that could modify discomfort and nociceptive activation. This consideration is relevant to both practical treatment planning and controlled sensory studies.
