Articulations © The McGraw−Hill Anatomy, Sixth Edition Companies, 2001 200 Unit 4 Support and Movement Synchondroses that do not ossify as a person ages are those Proximal epiphysis of humerus that connect the bones of the floor and sides of the cranium and include the joints between the occipital, sphenoid, temporal, and Proximal epiphyseal plate (site of synchondrotic joint) ethmoid bones. In addition, the costochondral articulations be- tween the ends of the ribs and the costal cartilages that attach to the sternum are examples of synchondroses. Elderly people often exhibit some ossification of the costal cartilages of the rib cage. This may restrict movement of the rib cage and obscure an image of the lungs in a thoracic radiograph.

SYNOVIAL JOINTS The freely movable synovial joints are enclosed by joint capsules containing synovial fluid. Based on the shape of the articular sur- faces and the kinds of motion they permit, synovial joints are cate- Distal epiphyseal gorized as gliding, hinge, pivot, condyloid, saddle, or plate ball-and-socket. Distal epiphysis Objective 8 Describe the structure of a synovial joint. The function of synovial joints is to pro- occurs at both the proximal and distal epiphyseal plates. The mitotic activity at synchondrotic joints is responsible for bone growth in vide a wide range of precise, smooth movements, at the same length. Synovial joints are the most complex and varied of the Synchondroses three major types of joints.

Pain receptors are free nerve endings that are present effects of aging in regard to specific body systems are also profiled 25mg antivert with mastercard. The pain sensations elicited by disease or trauma are important in localizing and diagnosing specific dis- eases or dysfunctions effective antivert 25 mg. Only a few of the many clinical considerations of the cen- tral nervous system will be discussed here. These include neuro- Creek logical assessment and drugs, developmental problems, injuries, (a) infections and diseases, and degenerative disorders. Third lumbar vertebra Neurological Assessment and Drugs Coccyx Neurological assessment has become exceedingly sophisticated and Spinal cord accurate in the past few years. In a basic physical examination, only the reflexes and sensory functions are assessed. But if the physician suspects abnormalities involving the nervous system, further neuro- logical tests may be done, employing the following techniques. Acis- needle ternal punctureis similar to a lumbar puncture except that the CSF is withdrawn from a cisterna at the base of the skull, near FIGURE 11. The pressure of the CSF, which is nor- needle between the third and fourth lumbar vertebrae (L3–L4) and mally about 10 mmHg, is measured with amanometer. Samples of (b) withdrawing cerebrospinal fluid from the subarachnoid space. In addi- tion, excessive fluid, accumulated as a result of disease or trauma, may be drained. With that speed, body functions as well as The condition of the arteries of the brain can be deter- structures may be studied.
