Introduction Millions of sensory neurons are delivering information to the CNS all the time Millions of motor neurons are causing the body to respond in a variety of ways Sensory and motor neurons travel by different tracts within the spinal cord. By Juan Garcia and Candice Markham. The Brain. This chapter addresses the relation of the nervous system to learning and behavior. The focus of the chapter is on the central nervous system (CNS), which comprises the brain and the spinal cord.. Chapter 48. YOU MUST KNOW. The anatomy of a neuron. . The role of active transport in establishing the membrane potential of a neuron. . How long-distance and short-distance signaling is done in neurons. . The Nervous System. Eating?.

In fact, your nervous system controls almost everything you do. Sensory systems receive information from the environment via specialized receptors in the periphery and transmit this information through a series of neurons and synaptic relays to the CNS. .

Neurons are masses of nerve cells that transmit information. Three main components:. (1) Cell Body – contains the nucleus and two extensions.

The sensory epithelium in each organ is the key component, although it is small relative to all the ancillary apparatus. pg. 5. Topic: . 10.2 Neuron Structure.

Biological psychologists study the ways in which our behavior and psychological processes are linked to biological structures and processes. Sensation, perception, memory, and thinking are all psychological processes that have at least a partly biological basis..
