What occurs when a constant unchanging stimulus is no longer noticed?
sensory adaptation
What is a simple automatic inborn response to a sensory stimulus?
n biology, an automatic and inborn response to a stimulus that involves a nerve impulse passing from a sensory nerve cell to a muscle or gland without reaching the level of consciousness. Simple reflexes include sucking, swallowing, blinking, scratching, and the knee jerk. Most reflexes consist of complex patterns of many unconsciously coordinated muscular actions that form the basis of much instinctive behavior in animals. Examples include walking, standing, the cat's righting reflex, and basic sexual acts.
What is the different between an external stimulus and an internal stimulus?
The difference between an external stimulus and an internal stimulus is that an external stimulus is a stimulus that comes from outside an organism. But an internal stumulus is a stimulus that comes from inside an organism. An example for an external stimulus can be that when you are cold, you put on a jacket. An example for an internal stimulus is that when you feel hungry, you eat food.
In positive feedback the initial stimulus produces a response that the stimulus?
exagerrates the stimulus
What is a change in an organism's surrounding that causes the organism to react?
The answer to this would mose probabaly be a stimulus. Because there are 2 types of stimuli Internal Stimulus and External Stimulus and so it has to be either one of these but the answer is stimulus.
What are the very first of the three steps basic to all sensory systems?
1. Recieve stimulus 2. Transform stimulus 3. Deliver stimulus
Which neurons decide about the action for a certain stimulus?
Sensory neuron
Simple automaticinborn response to a sensory stimulus?
reflex
What is the process of receiving stimulus energy called?
The process of receiving stimulus energy is called sensory reception. It involves the detection of sensory stimuli by sensory receptors in the body, which then transmit signals to the brain for processing and interpretation.
What is a simple automatic inborn response to a sensory stimulus is?
reflex
Detect changes of internal or external stimulus?
sensory receptors
What is a reduction in sensitivity in the presence of a constant stimulus?
It is known as sensory adaptation. This occurs when our sensory receptors become less responsive to a constant stimulus over time, leading to a reduced perception of the stimulus. Sensory adaptation allows us to focus on new or changing stimuli that may be more relevant for survival.
What is the intensity of a sensation is determined by what?
The intensity of a sensation is determined by the magnitude of the stimulus that evokes it. This can be influenced by factors such as the strength or amount of the stimulus, the sensory receptors involved, and the sensory pathways that transmit the signal to the brain.
What is the organisms actions as a result of sensory neural and hormonal factors in response to changes in the external or internal conditions?
Stimulus
What neuron picks up a stimulus?
A sensory Neuron picks up the stimulus from the environment and changes it into a nerve impulse.
What is a decreased sensitivity that occurs when a stimulus is continuously applied to sensory receptors called?
This is known as sensory adaptation. It is a decrease in responsiveness of sensory receptors to constant stimulation.
When a stimulus is applied to a sensory ending what kind of potential is produced?
When a stimulus is applied to a sensory ending, it can lead to the generation of a receptor potential. This receptor potential is a graded potential that can trigger an action potential along the sensory neuron, leading to the transmission of the sensory input to the central nervous system for processing and interpretation.
