The Cardiovascular System: The Heart, 19.2 Cardiac Muscle and Electrical Activity, Chapter 20. These nerve endings are present in the ears, eyes, nose and mouth. The pain and temperature receptors in the dermis of the skin are examples of neurons that have free nerve endings. This book uses visual analogies to assist the student in learning the details of human anatomy and physiology. The nervous system is the master controlling and communicating system of the body. Nerve impulses from these specialized nerve endings travel to specific areas of the brain . Throughout, the in-text material is supported by essays that demonstrate the application of student knowledge to real-world veterinary practice. The cells that interpret information about the environment can be either (1) a neuron that has a free nerve ending (dendrites) embedded in tissue that would receive a sensation; (2) a neuron that has an encapsulated ending in which the dendrites are encapsulated in connective tissue that enhances their sensitivity; or (3) a specialized receptor cell, which has distinct structural components that interpret a specific type of stimulus (Figure 13.1.1). If strong enough, the graded potential causes the sensory neuron to produce an action potential that is relayed into the central nervous system (CNS), where it is integrated with other sensory information—and sometimes higher cognitive functions—to become a conscious perception of that stimulus.
