The adductor pollicis muscle is an intrinsic muscle of the hand which lies in the deepest muscular plane of the palm, within the adductor compartment. Here's the 10th Edition of this classic text. These nodes then drain into the deep brachial and deltopectoral lymph nodes and ultimately terminate at the infraclavicular and axillary lymph nodes. The signaling centers include the apical ectodermal ridge (AER) which controls proximal-distal signaling by inducing differentiation of underlying mesoderm and programmed cell death of interdigital tissue, the zone of polarizing activity (ZPA) which controls radioulnar limb formation via production of sonic hedgehog protein (SHH), and the Wnt pathway which regulates the ventral/dorsal limb axis.

These patients typically present with intrinsic muscle atrophy, leading to weakened pinch and grasp strength, difficulty turning keys, and difficulty with activities requiring manual dexterity. This surgery, combined with a patient dedicated to post-operative rehabilitation, typically has a very good prognosis in regards to regaining dexterity. Because the thumb is orientated perpendicular to the other digits, its movements are modulated by a diverse set of specific muscles within the hand. The adductor pollicis is an important anatomical landmark for the radial artery. Emphasizing clinical anatomy, the text integrates current information from an array of medical disciplines into the discussions of the nervous system and sensory organs, including in-depth coverage of key topics, including molecular 2009 Oct [PubMed PMID: 20069147], House JH,Gwathmey FW,Fidler MO, A dynamic approach to the thumb-in palm deformity in cerebral palsy. Injury to the ulnar collateral ligament (UCL) of the thumb occurs secondary to hyperabduction or hyperextension mechanisms imposed at the MCP joint. Anesthesiologists are then able to deliver customized signals via the electrodes, and the accelerometer recordings are then able to guide subsequent medication and treatment delivery based on the level of neuromuscular blockade.
