Physiology labs essays Properties of the Isolated Mammalian If we were to compare smooth muscle with skeletal muscle we notice that they are very different from one another. Firstly, smooth muscles have a slow cycling of myosin cross bridges as compared to skeletal muscle. However, the fraction of time that the cross bridges remain attached to the actin filaments is believed to be greatly increased in smooth muscle. Secondly, Less energy is required to sustain the same tension of contraction in smooth muscle as in skeletal muscle. Thirdly, The maximum force of contraction of smooth muscle is often even greater than that of skeletal muscle. This great force of smooth muscle contraction results from the prolonged period of attachment of the myosin cross-bridges to the actin filaments. The Gastrointestinal tract has 2 major networks of nerve fibers - Myenteric plexus and the Submucous plexus. The plexuses are interconnected, and they contain motor neurons that innervate the smooth muscle. This is the enteric nervous system. The intestine also receives a dual extrinsic innervation from the autonomic nervous system, with parasympathetic cholinergic activity generally increasing the activity of intestinal smooth muscle and the sympathetic noradrenergic activity generally decreasing it while causing the sphincters to contract. The GI tract is made up of smooth muscles. The individual smooth muscle fibers are between 200 and 500 micrometers in length and 2 and 10 micrometers in diameter, and they are arranged in bundles of as many as 1000 parallel fibers. In general, smooth muscle can be divided into Visceral smooth muscle and Multi-unit smooth muscle. Visceral smooth muscle occurs in large bundles. Within each bundle, the muscle fibers are electrically connected with one another through large numbers of gap junctions that allow low-resistance movement of ions from one cell to the next. Each layer functions as a syncytium; that is, when an action potenti...

Project 8 - Speech or Presentation Example These parameters generate secondary parameters such as total cost, total revenue, average cost, and marginal revenue. All of them are interrelated. This assignment studies the interrelationship of these parameters using two equations: inverse demand and average cost. The inverse demand equation is represented by p = 800 – q and the average cost equation is expressed by c = q + 100 + 500/ q. The following sections present the interdependency of the above-mentioned primary and secondary parameters of the price and demand relationship. The inverse demand equation is p = -q + 800. Therefore, the demand equation is q = - p + 800. This equation is coded in the Mathematica program to draw the 2D plot of the demand curve. The plot is drawn on the q-p plane; where q is independent variable quantity and p is the dependent variable demand. The plot is shown in Figure 2. Given Inverse demand function is p= -q + 800; therefore, Demand function is q = -p + 800. The formula for the calculation of Elasticity of demand is E = = *d(-q+800)/dq. This formula is coded in the Mathematica , which are shown below. The demand elasticity for price, p =1 is E = -1/799. Since E Given average cost function, AC = q + 100 + 500 / q. For total quantity q, the total cost function is TC = (q+100+500/q)*q= q2 + 100q + 500. Marginal cost, MC is the tangent to TC function, which is expressed as The MC function will be expressed through q variable. The solution is MC = TC’[1]. The solution is coded in Mathematica, which are shown below. We use the 3D profit function, f(π3D) = pq - q2 -100 q - 500. In this equation, p and q are independent variables. At the same time, for a given value of p there is a specific value of q. We find the values of q for p using p = - q + 800 equation. We assign p from 1 to 10 with interval 1. The 3D function and their arguments are coded in Mathematica. We have included a table of π3D = f (p, q)
