The central motor system is arranged as a hierarchy of control levels, with the forebrain at the top and the spinal cord at the bottom (see table 14. 1

Somatic sensation enables our body to feel, to ache, to chill, and to know what its parts are doing. It is sensitive to many kinds of stimuli. The cent

The motor system consists of all our muscles and the neurons that control them. The spinal cord contains certain motor programs for the generation of c

The sense of hearing is known as audition and the sense of balance is regulated by the vestibular system. When an object moves toward a patch of air, i

The vestibular system monitors the position and movement of the head, gives us a sense of balance and equilibrium, and helps coordinate movements of th

Recall that all factors, particularly capital, are variable in the long-run. Entry into or exit from the industry by firms of the same size as existing

Profit = total revenue (p*q) total costs. = total revenue variable costs (in economic terminology) (operating profit = producer surplus in economic ter

We first examine the cost of firms in the period when capital is fixed to understand the importance of marginal cost in the determination of profit max

Suppose that the consumer (household) consumes only two goods (x and y). Given the prices of the two goods (px, py) and the consumer"s income (m), the

We can analyze demand and supply and market equilibrium with linear equations. These are equations of the form y = a + bx where a is the y-intercept, i

Our understanding of elasticity will help us analyze the impact of sales taxes or subsidies on equilibrium price and quantity. The simplest sales tax i

Definition: elasticity measures the responsiveness of a change in a variable to the change in another variable. Definition: price elasticity of demand
