Describe the four components involved in the perception of a sensation?
The four components involved in the perception of a sensation are stimulus, sensory receptors, neural processing, and perception. Stimulus is the physical energy that triggers a response in sensory receptors. Sensory receptors detect the stimulus and convert it to neural signals. Neural processing occurs when these signals are transmitted to the brain and interpreted. Perception is the conscious awareness and interpretation of the sensation.
What three cranial nerves are involved in the cardinal positions of gaze?
vagus, glossopharyngeal and facial
What is the function of the glossopharyngeal nerve?
The glossopharyngeal nerve is responsible for providing sensory information from the back of the throat, taste sensation from the back of the tongue, and motor function to some of the muscles involved in swallowing. It also plays a role in regulating blood pressure and monitoring oxygen levels in the blood.
What cranial nerve is involved if you are experiencing problems moving your tongue pressure?
Cranial nerve 9: glossopharyngeal
A cranial nerve involved in taste?
When taste buds are stimulated they can produce 4 different sensations (sweet, salty, bitter, sour). These nervous impulses are carried to the brain by the facial nerve (cranial nerve VII)from the anterior 2/3 of the tongue and by the glossopharyngeal (cranial nerve IX) from the posterior 1/3 of the tongue.
What is the transmissor for the sense of taste?
The gustatory pathway has a more complicated course. There are more fiber tracts involved in the transmission of the neural impulses for taste. The facial nerve transmits gustatory signals or messages from the anterior two-third of the tongue. However, for the posterior one-third of the tongue,the glossopharyngeal nerve is responsible for the transmission of the gustatory signals along the pathway.
What are 3 cranial nerves involved in the sense of taste?
Auditory, Glossopharyngeal, Hypoglossal
What type of receptor is involved in the sensation of pain?
The type of receptor involved in the sensation of pain is called nociceptors. These specialized nerve cells detect harmful stimuli and send signals to the brain to perceive pain.
What areas does sorting and editing of impulses take place?
Sorting and editing of impulses take place in the prefrontal cortex, which is responsible for executive functions such as decision making, problem solving, and controlling impulses. Additionally, the amygdala, which is involved in emotional processing, can also play a role in filtering and modulating impulses.
How is the pace maker involved in your heart beat?
The pace maker uses electrical impulses to regulate heart rate. It is used when the bodies own impulses from the brain are not able to do the job anymore.
What are the chemicals involved in malaria?
Malaria is caused by the parasite plasmodium, which is transmitted by mosquitos.
What is the amygdala involved in?
The amygdala is the center of all emotional impulses that stores emotional memory. It is located in the limbic system of the brain.
