Anatomical, Histological, and Morphometrical Investigations of the Auditory Ossicles in Chlorocebus aethiops sabaeus from Saint Kitts Island

Simple Summary The present paper explores a series of macromorphological, micromorphological, and morphometrical aspects of the auditory ossicles of the green monkey. The particular aspects of the gross morphologies of the three ossicles are described in detail, comparing data with those on other primates and non-primates, underlining the most important features. This study adds some histological insights (never before described to the present date) on all three adult auditory ossicles and supplies a series of metrical data (raw and other complex interpretations of data) to complete the knowledge of the functional anatomy of the lever system in ear ossicles. Abstract Otological studies rely on a lot of data drawn from animal studies. A lot of pathological or evolutionary questions may find answers in studies on primates, providing insights into the morphological, pathological, and physiological aspects of systematic biological studies. Our study on auditory ossicles moves from a pure morphological (macroscopic and microscopic) investigation of auditory ossicles to the morphometrical evaluation of several individuals as well as to some interpretative data regarding some functional aspects drawn from these investigations. Particularities from this perspective blend with metric data and point toward comparative elements that might also serve as an important reference in further morphologic and comparative studies.
