This is because each metacarpal head generic propranolol 80mg without a prescription braunwalds heart disease 9th edition free download, although rounded at its distal extremity buy propranolol 40mg low price cardiovascular health study, is ﬂattened anteriorly; when the base of the proximal phalanx moves on to this ﬂattened surface, side move- ments become impossible. Moreover, the collateral ligaments on either side of the m/p joints become taut in ﬂexion and thus prevent abduction and adduction. The m/p joints of the ﬁngers, but not the thumb, are linked by the tough, which prevent any spreading of the palm when a ﬁrm grip is taken. All the () have pulley-shaped opposing surfaces and are therefore hinge-joints allowing ﬂexion and extension only. Posteriorly—the joint capsule is replaced by the expansion of the exten- sor tendon of the digit concerned. The sources of blood supply of the femoral head—along the ligamentum teres, through the diaphysis and via the retinacula. Inferiorly, this crest splits into the medial and lateral, leaving a ﬂat between them. The lower end of the femur bears the prominent which are separated by a deep posteriorly but which blend anteri- The bones and joints of the lower limb Fig. Note that the psoas tendon and the femoral artery are intimate anterior relations of the joint. To the surgeon, the examiner and, therefore, the student it is also the most important. Its articular surfaces are the femoral head and the horse-shoe shaped articular surface of the acetab- ulum, which is deepened by the ﬁbrocartilaginous. The of the hip is attached proximally to the margins of the acetab- ulum and to the transverse acetabular ligament. Distally, it is attached along the trochanteric line, the bases of the greater and lesser trochanters and, pos- teriorly, to the femoral neck about 0. Note that acute osteomyelitis of the upper femoral metaphysis will involve the neck which is intracapsular and which will therefore rapidly produce a secondary pyogenic arthritis of the hip joint. Three ligaments reinforce the capsule: the (Y-shaped ligament of Bigelow) — which arises from the anterior inferior iliac spine, bifurcates, and is inserted at each end of the trochanteric line (Fig. Of these, the iliofemoral is by far the strongest and resists hyperexten- sion strains on the hip. If the hip is forced into posterior dislocation while adducted (a), there is no associated fracture of the posterior acetabular lip (b). Dislocation in the abducted position (c) can only occur with a concomitant acetabular fracture (d). The palatine tonsil lies in the between the anterior and poste- rior pillars of the fauces. The anterior pillar, or, forms the boundary between the buccal cavity and the oropharynx; it fuses with the lateral wall of the tongue and contains the palatoglossus muscle. The poste- rior pillar, or, blends with the wall of the pharynx and contains the palatopharyngeus (Fig. The ﬂoor of the tonsillar fossa is formed by the superior constrictor of the pharynx separated from the tonsil by the, which is a thick condensation of the pharyngeal submucosa (the pharyngobasilar fascia). This capsule is itself separated from the superior constrictor by a ﬁlm of loose areolar tissue. This epithelium is pitted by, up to twenty in number, and often bears a deep in its upper part. The lymphoid material may extend up to the soft palate, down to the tongue or into the anterior faucial pillar. On either side of the larynx the pharynx forms a recess, the, in which swallowed foreign bodies tend to lodge. The muscles of the larynx function to open the glottis in inspiration, close the vestibule and glottis in deglutition and alter the tone of the true vocal cords in phonation. The remaining muscles constitute a single encircling sheet whose various attachments are denoted by the names of its separate parts: the Relations Fig. Lesions of the retina or optic nerve result in in the affected segment, but lesions of the optic tract and central parts of visual pathway result in contralateral.
