The Function Of James And Musculoskeletal System

Decent Essays

Case Introduction
James Walsh, a 55-year-old-male presented symptoms including weakness inferiorly in his right lower limb and difficulty performing simple tasks such as walking or tying his shoelace. He also had some difficulties swallowing and often experiences unpredictable movements due to lack of control. As a result, he primarily uses a wheelchair and requires careful assistance when performing everyday activities.
The function of James’ musculoskeletal system is primarily to facilitate movement as the contraction of his muscles pull on bone to carry out an action. It also contributes to heat production for enzymes to function, stability by resisting unwanted movement and maintains his posture (Saladin, K S., 2007). This is important …show more content…

However, James’ case of spastic cerebral palsy alters the interaction between the musculoskeletal and nervous system in some areas which are affected.

Case Examination
James’ condition of spastic cerebral palsy impacts the regulation of muscle tone due to the effect of spinal reflexes when muscles are slightly contracted (Ballard, F., 2016). Muscle tone is dependent on the release of alpha motor neurons in the spinal cord (Albright, A.L., 1995). This is regulated when there is a balance between excitatory impulses and inhibitory impulses. James’ condition of cerebral palsy indicates that there is an imbalance between excitatory impulses and inhibitory impulses. The imbalance between these impulses causes a lack in regulation of muscle tone due to the insufficient release of alpha motor neurons in the spinal cord (Albright, A.L., 1995). James’ excess production of excitatory impulses originates in the golgi tendons of organs and muscle spindle, a specialised sensory receptor in the muscle (Albright, A.L., 1995). The impulse then passes through afferent nerves into the spinal cord and releases excitatory neurotransmitters. In contrast, the lack of ability to generate inhibitory impulses suggest that the regions of the brain responsible for the generation of inhibitory impulses including the basal ganglia, brain stem and cerebellum may be damaged (Albright, A.L., 1995). Consequently, the excess of excitatory impulses may result in
