A lot are those behaviours that we consider to be involuntary (e. g. , sneezing) A reflex is a relatively simply, automatic response to a stimulus. Startle response- a defensive reaction to a sudden, unexpected stimulus; involves the automatic tightening of skeletal muscles as well as various hormonal and visceral (internal organ) changes. Orienting response we automatically position ourselves to facilitate attending to a stimulus. Can involve a relatively major body movement, such as when we automatically turn in response to an unfamiliar noise behind us. Vomiting reflex which expels potentially poisonous contents from the digestive system. Reflex arc- a neural structure underlying some reflexes that consist of sensory neuron, an interneuron, and a motor neuron. A fixed action pattern is a fixed sequence of responses elicited by a specific stimulus (e. g. , spiders building webs)
