Chapter 6: Coordination
You should be able to...
- 2.79 understand that a coordinated response requires a stimulus, a receptor and an effector
- 2.83 describe how responses can be controlled by nervous or by hormonal communication and understand the differences between the two systems
- 2.84 understand that the central nervous system consists of the brain and spinal cord and is linked to sense organs by nerves
- 2.85 understand that stimulation of receptors in the sense organs sends electrical impulses along nerves into and out of the central nervous system, resulting in rapid responses
- 2.86 describe the structure and functioning of a simple reflex arc illustrated by the withdrawal of a finger from a hot object
- 2.87 describe the structure and function of the eye as a receptor
- 2.88 understand the function of the eye in focusing near and distant objects, and in responding to changes in light intensity
