A simple automatic inborn response to a sensory stimulus is called a(n)?
A simple automatic inborn response to a sensory stimulus is called a reflex. Reflexes are involuntary and often occur without conscious thought, serving as a protective mechanism for the body. They involve a direct pathway known as a reflex arc, which includes sensory neurons, interneurons, and motor neurons. Examples include the knee-jerk reaction or withdrawal from a painful stimulus.
What polysynaptic reflexes have a neuron?
The withdrawal reflex is an example of a polysynaptic reflex involving multiple neurons. This reflex pathway consists of sensory neurons carrying the stimulus information to the spinal cord, interneurons within the spinal cord processing the information, and motor neurons sending signals to muscles to initiate a response, such as withdrawing from a painful stimulus.
What interneurons in a withdrawal reflex are located in the?
The interneurons involved in a withdrawal reflex are located in the spinal cord. These interneurons receive signals from sensory neurons that detect the painful stimulus and transmit signals to motor neurons that cause the withdrawal response. The spinal cord acts as a relay station for these signals, allowing for a quick and automatic response to potential harm.
The learning of phobias is a very good example of which certain type of classical conditioning?
The learning of phobias is a good example of classical conditioning known as "conditioned emotional response." This occurs when a neutral stimulus (like a spider) becomes associated with a negative response (fear) through repeated pairings with an unconditioned stimulus (like a painful experience or trauma).
An intensely painful stimulus is distinguished from a mildly painful one by:?
a higher frequency of action potentials initiated.
What is arm reflex?
The arm reflex, often referred to as the arm withdrawal reflex, is a rapid, involuntary response that occurs when the skin or underlying tissues of the arm are stimulated by a painful or potentially harmful stimulus. This reflex action involves sensory neurons detecting the stimulus and transmitting signals to the spinal cord, which then sends a quick signal back to the muscles in the arm to withdraw from the source of pain. It serves as a protective mechanism, helping to minimize injury. This reflex is part of the body's broader neurological responses to danger.
Identify and describe how an organism could respond to an external stimulus and describe a response to an internal stimulus?
An example of an external stimulus is a painful prick (and any other stimulus that happens OUT side the organism ). The organism could respond by pulling away from the pain caused by the stimuli. An example of an internal stimulus is the feeling of hunger or thirst (or any other stimulus that happens IN side the organism). The organism could respond by eating or drinking. a behavior
What is the lowest functioning of a coma patient according to the Glasgow Coma Scale?
Three is the least possible number of total points and would be given to a patient for whom not even a painful stimulus is sufficient to provoke a response.
Describe the neural pathways that are activated when you hit your thumb with a hammer?
They would include the afferent neurons, starting from the median nerve then traveling up to where it meets the ulnar and radial nerves in the brachial plexus. From there they would enter the central nervous system via the spinal cord and up to your parietal lobes after passing through the thalamus. Then your frontal lobe's left side, in an area called Broca's area, would trigger efferent motor neurons to make you say, "Ouch!"
The painful stimulus that causes a hand to pull away from a hot iron?
withdrawal reflex
What is the middle functioning of coma patient according to the Glasgow Coma Scale?
In the middle are those patients who may be able to respond, but who require an intense or painful stimulus, and whose response may demonstrate some degree of brain malfunctioning
What is the medical term for diminished sensation to pain?
Hypoalgesia is the medical term for diminished sensation to pain. It refers to a reduced sensitivity to painful stimuli, where individuals may experience less pain than expected in response to a stimulus that would typically be painful.
