Accepted Answer

The answer of The integration centers for sensations that are...

Question 2

List the six types of sensory receptors categorized based on the type of stimulus they detect and describe the types of stimuli that each type can detect.

Accepted Answer

The answer of List the six types of sensory receptors...

Question 3

Which condition is a state of unconsciousness in which a person's responses to stimuli are reduced or absent?

Accepted Answer

Coma is a state of unconsciousness in which a person is unable to respond to stimuli, whether they be auditory, visual, or physical. In a coma, a person's brain function is greatly suppressed, and they are unable to wake up or respond to their surroundings.

Question 4

Infants spend approximately 50% of their sleeping time in

Accepted Answer

Infants spend approximately 50% of their sleeping time in REM sleep. This is because REM sleep is important for brain development and consolidation of memories, both of which are critical for infants during their early stages of development.

Question 5

Which of the following stages of non-rapid eye movement (NREM)sleep is considered the deepest level of sleep?

Accepted Answer

Stage four is the deepest level of NREM sleep, also known as slow-wave sleep, characterized by slow brain waves, relaxed muscles, and a decreased heart rate. It is the most restorative stage of sleep, and disruptions to this stage can lead to feelings of grogginess and fatigue upon waking up. However, some researchers believe that splitting stage three and stage four into separate stages may be more accurate.

Question 6

All of the following result from some form of malfunction by the basal nuclei EXCEPT

Accepted Answer

Synesthesia is not known to be caused by malfunction of the basal nuclei. The other options all involve dysfunctions of the basal nuclei, including Huntington's disease, Parkinson's disease, Tourette's syndrome, and obsessive-compulsive disorder.

Question 7

Which disorder is characterized by involuntary periods of sleep that occur throughout the day?

Accepted Answer

Narcolepsy is a sleep disorder characterized by sudden, uncontrollable, and involuntary periods of sleep occurring throughout the day.

Question 8

What are the three types of sensory receptors categorized based on their location and the origin of stimuli that activate them? What is the nature of the stimuli that cause their excitation?

Accepted Answer

The answer of What are the three types of sensory...

Question 9

_____ is a term used to describe pain that is felt at a site remote from the place of origin.

Accepted Answer

Referred pain is the term used to describe pain that is felt at a site remote from the place of origin. This pain may be felt in a different area than where the injury or dysfunction is located, often due to shared neural pathways in the body.

Question 10

What is phantom limb sensation and describe why the patient experiences these sensations?

Accepted Answer

The answer of What is phantom limb sensation and describe...

Question 11

The process of sensation begins in a _____,which can be either a primary sensory neuron or a separate cell.

Accepted Answer

Sensory receptors are specialized cells that detect and respond to stimuli in the environment, initiating the process of sensation. They can be either primary sensory neurons that directly detect the stimulus or separate cells that synapse with primary sensory neurons to relay the stimulus information.

Question 12

Which disorder is characterized by a person's breathing repeatedly stopping for 10 or more seconds while sleeping?

Accepted Answer

Sleep apnea is a disorder where a person's breathing repeatedly stops for 10 or more seconds while sleeping. Narcolepsy is a disorder characterized by sudden, uncontrollable episodes of sleep during the day. Insomnia is a disorder where a person has difficulty falling asleep or staying asleep. Coma is a state of prolonged unconsciousness. Amnesia is a loss of memory.

Question 13

Which of the following regions of the brain compares the intentions of skeletal muscle movements with the actual movement performed and then sends out corrective feedback to upper motor neurons?

Accepted Answer

The cerebellum compares the intended movement with the actual movement and sends corrective feedback to the upper motor neurons to adjust the movement.

Question 14

During the process of learning,the brain shows a characteristic called _____,which is the ability to change in response to intensive usage for a particular task like memorizing a page of physiology notes.

Accepted Answer

The characteristic mentioned in the question is brain plasticity, which refers to the brain's ability to change and form new connections in response to experience and learning. Bradykinesia, hypokinesia, amnesia, and palsy do not relate to this phenomenon.

Question 15

Which condition is characterized by a lack of memory for events occurring after the trauma or disease that caused the condition?

Accepted Answer

Anterograde amnesia is characterized by the inability to form new memories after a traumatic event or disease. It does not affect the ability to recall events that occurred prior to the trauma.

Quiz 16: Sensory, Motor and Integrative Systems

The integration centers for sensations that are consciously perceived (like vision,smell,taste,and pain) are found in the
