A Textbook of Head and Neck Anatomy

A Textbook of Head and Neck Anatomy

This textbook is designed to be used in conjunction with "A colour atlas of head and neck anatomy" by McMinn. The material is arranged in the same order, the same terminology is employed and figure references are given alongside the text. The work covers the topographical anatomy of the head, neck and brain including a section on neurology. Detailed line drawings accompany the text and the dissections in the "Atlas", while case histories are included after each chapter. Complex materal has been summarized in graphical form. The head is positioned upon the superior portion of the vertebral column, attaching the skull upon C-1 (the first cervical vertebra known as the atlas). The skeletal section of the head and neck forms the superior segment of the axial skeleton and comprises skull, hyoid bone, auditory ossicles, and cervical spine. The skull can be further subdivided into: (a) cranium (8 bones: frontal, 2-parietal, occipital, 2-temporal, sphenoid, ethmoid), and (b) facial bones (14 bones: 2-zygomatic, 2-maxillary, 2-palatine, 2-nasal, 2-lacrimal, vomer, 2-inferior conchae, mandible). As the fetus develops, the facial bones usually form into pairs and then fuse together. As the cranium fuses, sutures are formed that resemble stitching between bone plates. In a newborn, the junction of the parietal bones with the frontal and occipital bones, form the anterior (front) and posterior (back) fontanelle, or soft spots. The separation of the cranial bone plates at time of birth facilitate passage of the head of the fetus through the mother's birth canal, or pelvic girdle. The parietal bones, and occipital bone can overlap each other in the birth canal, and form the unusual looking "cone head" appearance in a newborn when delivered in a natural, or vaginal, delivery. The occipital bone articulates with the atlas near the foramen magnum. The atlas articulates with the occipital condyle superiorly and the axis inferiorly. The spinal cord passes through the foramen magnum providing continuity for the central nervous system (CNS). Articulation of the neck includes: flexion, extension, (nodding yes), and rotation (shaking head no). Blood circulates from the upper systemic loop originating at the aortic arch, and includes: the brachiocephalic artery, left common carotid artery and left subclavian artery. The head and neck are emptied of blood by the subclavian vein and jugular vein. ! Uwagi: Oprawa lekko zakurzona, zarysowana. Brzegi stron zakurzone, zabrudzone. Strony lekko pożółkłe.
