Temporal Bone Anatomy (Cadaveric Dissection) Iowa Head

Each temporal bone is composed of five osseous parts: the squamous, mastoid, petrous, tympanic, and styloid portions. Several intrinsic channels, intrinsic fissures, and extrinsic sutures are often apparent on CT images and can mimic fractures (pseudofractures) (1) The temporal bone consists of the lateral skull base, forming portions of the middle and posterior fossa (a hollow space in the skull, near the brainstem and cerebellum). The five osseous components of the temporal bone are the squamous, mastoid, petrous, tympanic, and styloid portions(6) Interactive Atlas. This atlas allows you to scroll through CT slices of the temporal bone in four different planes. Click on an image to select a plane. Axial plane. Coronal plane. Parallel plane. Perpendicular plane Temporal Bone Anatomy and Function. The temporal bone is divided functionally into the outer ear, middle ear, and inner ear (Figure 1). As sound enters the ear, it travels through the external auditory canal, vibrates the tympanic membrane and middle ear bones (also called ossicles) (Figure 2), and then is translated into a neural impulse by. 5a. 4. The Temporal Bone - Human Anatomy. The temporal bones are situated at the sides and base of the skull. Each consists of five parts, viz., the squama, the petrous, mastoid, and tympanic parts, and the styloid process.: The Squama (squama temporalis).—The squama forms the anterior and upper part of the bone, and is scale-like, thin, and translucent

The temporal bone is a thick, hard bone that forms part of the side and base of the skull. This bone protects nerves and structures in the ear that control hearing and balance The temporal bone (os temporale; L., the temple) forms portions of the sides and base of the skull. 1 2 It is anatomically divided into four regions called the squamous, mastoid, temporal, and petrous parts Temporal bone The middle ear consists of the tympanic cavity and the antrum. The antrum is a large aircell superior and posterior to the tympanic cavity and connected to the tympanic cavity via the aditus ad antrum

INTRODUCTION • Temporal bone is a composite structure consisting of tympanic bone, mastoid process, squama and petrosa. • Styloid process eventhough is closely associated with temporal bone, is not considered as a part of it. • From lateral view, tympanic, squamous and mastoid portions are seen Temporal bone. Temporal bone, by the way, is the most complex bone in our body. It is embryologically formed by the fusion of 11 ossification centers * that incorporate the peripheral part of the audio-vestibular system and provide all necessary channels and openings for multiple cranial nerves & blood vessels passing through it. * Navjot Singh
