| Abstract | A human being can perform many different movements to adapt to variable environment, all these skills are extraordinary feats of coordination and control. It is believed that they result from the human hierarchical motor control system. This system is a complex nonlinear system including highly integrated neural centers in the brain and the spinal cord, many actuators constructed by muscles and bones and numerous sensory receptors. It is believed that the neuro-musculoskeletal model of human motor control system is very important to understand the characteristics of the system and many neuro-musculoskeletal models were presented over the past decades. In this paper, dynamic behavior and mechanism of the neuro-musculoskeletal model presented in are investigated. It is a single joint reflex model with agonist and antagonist muscles. Some intrinsic properties of the system model such as behavior of the moment arms, characteristics of force and stabilization are presented. The results reveal some inherit properties in the system. Firstly, to guarantee a unique equilibrium point of the system, the descending neuron control commands must be selected in special range; Secondly, the reflex regulation in spinal control circuit, i.e., the feedback from Renshaw cells and gamma motor neurons, are not absolutely necessary to ensure the system stable, the system can still converge to a equilibrium point with the constant muscle activations. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
