Chapter 19 Control of Movement: The Motor Bases of Animal Behavior
Outline
Neural Control of Skeletal Muscle Is the Basis of Animal Behavior
- Invertebrate neural circuits involve fewer neurons than vertebrate circuits
- Vertebrate spinal reflexes compensate for circumstances, as well as initiate movements
- BOX 19.1 Muscle Spindles
- Motor neurons are activated primarily by CNS input rather than by spinal reflexes
Neural Generation of Rhythmic Behavior
- Locust flight results from an interplay of CNS and peripheral control
- There are different mechanisms of central pattern generation
- BOX 19.2 Circuits and Elaborations of Central Pattern Generators: The Stomatogastric Ganglion
Control and Coordination of Vertebrate Movement
- Locomotion in cats involves spinal central pattern generators
- Central pattern generators are distributed and interacting
- The generation of movement involves several areas in the vertebrate brain
- BOX 19.3 Basal Ganglia and Neurodegenerative Diseases
