Aim: to study guinea pig’s and rat’s ears under light microscopy (LM) and scanning electron microscopy (SEM) and understand their anatomical advantages in basic otologic research. Materials and methods: The temporal bones, tympanic bullas and cochleas from three albino guinea pigs and rats were photographed and analyzed under LM and SEM.

2023年2月1日 · In the present study, we investigated the anatomy of the rat E-tube, obtained essential anatomical parameters of the rat E-tube, and illustrated the histological characteristics of the E-tube and its surrounding tissues.

2003年6月25日 · The rat’s ear is an organ of hearing and equilibrium. It is made up of the outer or external ear, the middle ear, and the inner ear. The outer or external ear is composed of the concha auriclae (or pinna), seen as the large outer flap of the ear, and the auditory canal.

2018年1月1日 · The ear of mice, rats, and humans detects sound and maintains balance. In mammals, this “stato-acoustic” system is traditionally divided into three structural units: the external, middle, and inner ear. The external and middle ear are designed to receive, transmit, and amplify sound.

The topographic anatomy of the albino rat middle ear is described. A set of microphotographs with matching illustrations presents the structural details at several surgical exposures. Anatomic differences between the rat, guinea pig, and cat are noted. This study was designed to aid experimental otologic studies of the rat middle ear.

Temporal bone marrow is thought to play important roles in relation to the inner ear, but is still largely uncharacterized, given this bone complex anatomy. We characterized the geometry and connectivity of rat temporal bone marrow using lightsheet imaging of …

2016年5月17日 · The topographic anatomy of the albino rat middle ear is described. A set of microphotographs with matching illustrations presents the structural details at several surgical exposures. Anatomic differences between the rat, guinea pig, and cat are noted.

A good understanding of the unique characteristics of rat temporal bone anatomy and exploration of surgical approaches for inner ear drug delivery and electrode insertion are essential for experimental research of the ear in rats. Temporal bone anatomy has been extensively described in humans and other mammals including the rat (Ding and Jiang ...

The external ear receives innervations from the vagus nerve which forms the auricular vagus nerve that specifically innervates the central concha in the middle region of the pinna, antihelix,...

2021年7月24日 · The ear of a rat may be divided into the external, middle, and inner ear. The external ear consists of the pinna and the external auditory canal which acts as a funnel to transmit the sound to the tympanic membrane which acts as the entrance to the middle ear.
