Receiving information from the environment to coordinate a response Pg. 180-185 Allows animals to detect and process signals to react to them Stimulus: a signal that causes an animal to react Example: touch, sound, smells, tastes Response: an animal’s reaction to a stimulus Types of Cells… Neuron: nerve cell with a unique structure for receiving and passing on information. Sensory Neuron: nerve cells that detect stimuli Interneurons: nerve cells that pass information between neurons Motor neurons: nerve cells that carry response information to muscles and other organs “Nerve net”: Simplest nervous system are a netlike arrangement of neurons throughout the body “Nerve cord”: Most complex have a nerve cord and a brain Brain: organized grouping of neurons in the head of an animal Receives info, interprets it and control’s an animal’s response Sense Organs • • Eyes, ears, nose detect stimuli in the form of sound, light, odor, and touch Mostly found in the head A frog detects vibrations with its tympanic membrane Platypus uses its bill to detect the movements of other animals Most insects detect some colors and movement with their compound eyes Shark uses cells in its nasal passages to detect tiny amounts of blood in sea water
