Peripheral nervous system
The peripheral nervous system consists of sensory and motor nerve endings, peripheral nerve trunks, plexuses and ganglia, which link the CNS with other parts of the body. Most of the neurones in the peripheral nervous system are, therefore, either afferent…
Cells of the nervous system
The functional unit of the nervous system is the nerve cell or neurone. These cells are highly specialised for the encoding, conduction and transmission of information. Neuroglial cells, or glia, are present in the nervous system in even larger numbers…
Introduction and overview
The nervous system of all animals functions to detect changes in the internal and external environments and to bring about responses in muscles, organs and glands that are appropriate for the preservation of the individual and the propagation of the…

Plate 4-1 Open full size image CONGENITAL DEFORMITIES OF THE THORACIC CAGE PECTUS EXCAVATUM Pectus excavatum is also called funnel chest, chonechondrosternon, or trichterbrust. It is a deformity of the anterior chest wall characterized by depression of the lower sternum…
DIAGNOSTIC PROCEDURES
TESTS OF PULMONARY FUNCTION RADIOLOGIC EXAMINATION OF THE LUNGS Chest radiography remains the primary imaging modality for initial evaluation of patients with suspected chest disease and in many cases not only identifies abnormalities but also allows a specific determination of…
PHYSIOLOGY
PULMONARY MECHANICS AND GAS EXCHANGE The major function of the lung is to deliver oxygen to and remove carbon dioxide from the blood as it passes through the pulmonary capillary bed. This function is achieved through a series of complex…
ANATOMY AND EMBRYOLOGY
RESPIRATORY SYSTEM The respiratory system is made up of the structures involved in the exchange of oxygen and carbon dioxide between the blood and the atmosphere, so-called external respiration . The exchange of gases between the blood in the capillaries…
Spine
Cervical Spine Axial 1 Pathologic Process Note on these images that the nasopharynx is often seen on cervical spine imaging. The neuroradiologist should always check for symmetry of the Eustachian tube opening and fossa of Rosenmüller just anterior to the…
