What body system is involved with processing the information from our surroundings?
The Nervous System
Information processing allows you to:
respond to your environment, regulate the internal processes of your body, learn and form memories from your experiences
__________ is the process by which the inside of the body maintains stable conditions and is controlled through feedback.
Homeostasis
_________ is a cycle of events in which information from one step controls or affects a previous step.
Feedback
___________ occurs when the body senses a change in its internal environment and activates processes that will slow or prevent the change.
Negative feedback
___________ occurs when the body activates processes that increase or reinforce the change.
Positive feedback
________________ are specialized cells in an animal’s nervous system that help an animal gather information about its environment.
Sensory receptors
___________- different types of environmental messages that sensory receptors respond to such as light, heat, or pressure.
Stimulus
__________ are specialized cells that information travels through when a sensory receptor detects a stimulus, it sends the information to the brain in the form of electrical energy.
Neurons
Sensory receptors can be organized by
the kind of stimuli with which they detect and respond.
Mechanical receptors detect
pressure, movement, and tension. Mechanical receptors detect the motion of sound waves, allowing animals to hear.
__________ receptors detect odors and tastes
Chemical
____________ receptors detect light.
Electromagnetic
____________ is the set of actions taken by an organism in response to stimuli
