Linear Model of Blood Flow, characteristics that help them to efficiently meet the needs of circulation. Under pathological conditions the vessels may become stiffer and less compliant, they may become smaller due to deposits on the inner surface, etc., all of which reduce the effectiveness of the cardiovascular system in tra

Signals and Systems Basics,gnals and systems by Fourier conversion into the “frequency-domain” simplifies a number of operations like convolution and differentiation to simple algebraic ones. This greatly enhances our power of analysis. This chapter outlines the basis of time-domain and frequency-domain analysis for physiological signals and systems.

Skeletal Muscle Contraction, Although this is a nonlinear model it is possible to linearize it into a form convenient for use in complex macroscopic models of movement. This linearized model can use many of the tools of systems analysis developed in preceding chapters. This reduced model satisfactorily predicts muscle behavior under a variety of situations.

External Stimulation of Excitable Tissue,f excitability is the propagating action potential model developed in the previous chapter. This model allows us to simulate and visualize the stimulation of nerves in realistic situations. It also provides a platform for understanding the stimulation of compound nerves and the concept of recruitment under artificial stimulation.

Neuromuscular Control,y important roles in the human body. The ideas developed in this chapter can be used to model such complex joints and their control. Analysis of complex movements like walking are based on such models of the musculoskeletal system under reflex control.
