Biology - Animal Behavior Flashcards
what are reflexes?
automatic response to environmental stimuli
where is a simple reflex controlled?
spinal cord
what is an example of an afferent neuron?
receptor
what is an example of an efferent neuron?
motor
what does the efferent nerve innervate?
the effector (a muscle or gland)
in what kind of organisms are reflexes most important?
lower ones (not vertebrates)
describe the path of a simple reflex in the spinal cord?
receptor cell; sensory neuron; interneuron; motor neuron; effector cell
where does the integration of a complex reflex take place?
cerebrum or brain stem
what is an example of a startle response?
responding to danger or hearing your name called
what is the reticular activating system?
controls the startle response, sleep-wake transitions and behavioral motivation
what are fixed-action patterns?
innate responses to patterns of environmental stimuli
what is the releaser in terms of responses?
the stimulus that elicits the behavior
are fixed-action patterns modified by learning?
no; the stimuli that trigger the fixed-action pattern is more easily modified
two examples of fixed-action patterns:
the maintenance/retrieval of female birds to their eggs; characteristic movements of animals that herd or flock
what are circadian rhythms?
daily cycles of behavior
how is the circadian rhythm maintained/modified?
initiated intrinsically and modified by external cues
what is the capacity for learning adaptive responses correlated with?
degree of neurologic development
