What does i stand for in CPi?
-
Ipsilateral
-
Contralateral
-
Prime
-
Midline
Correct Answer
A. IpsilateralExplanation
The letter "i" in CPi stands for Ipsilateral. Ipsilateral refers to the same side of the body or the same side of a structure. In the context of CPi, it likely represents a medical or anatomical term where "C" stands for contralateral, meaning the opposite side, and "Pi" represents ipsilateral, indicating the same side.Rate this question:

Posterior Tibial Nerve stimulator type
-
Between the Medial Malleolus & Achilles Tendon
-
Between tendons of the Palmaris Longus & Flexor Carpi Radialis
-
Lateral to the Palmaris Longus & standard wrist
-
Lateral portion of the knee running behind the Fibular Head
Correct Answer
A. Between the Medial Malleolus & Achilles TendonExplanation
The correct answer is "Between the Medial Malleolus & Achilles Tendon." This is because the posterior tibial nerve stimulator is typically placed in this location to stimulate the posterior tibial nerve, which is located between the medial malleolus (the bony prominence on the inner side of the ankle) and the Achilles tendon (the large tendon at the back of the ankle). Placing the stimulator in this location allows for targeted stimulation of the posterior tibial nerve, which can be beneficial for certain medical conditions.Rate this question:

Brainstem / Thalamic
Correct Answer
A. Brachial PlexusExplanation
The brachial plexus is the correct answer because it is a network of nerves that originates from the spinal cord in the neck region and supplies the upper limb with motor and sensory innervation. It is responsible for transmitting signals between the spinal cord and the arm, allowing for movement and sensation in the arm. The other options, such as the spinal cord, primary cortical somatosensory cortex, and brainstem/thalamic, are not directly involved in the innervation of the brachial plexus.Rate this question:

Correct Answer
A. Brachial PlexusExplanation
The Brachial Plexus is the generator of E. The Brachial Plexus is a network of nerves that originates from the spinal cord in the neck region and extends into the arm. It is responsible for providing motor and sensory innervation to the upper extremity, including the muscles and skin of the arm. Therefore, it is the correct answer for the generator of E.Rate this question:

Correct Answer
A. Primary Cortical Somatosensory CortexExplanation
The correct answer is the Primary Cortical Somatosensory Cortex. This is because the Primary Cortical Somatosensory Cortex is responsible for processing and interpreting somatosensory information, such as touch, pressure, temperature, and pain. It receives input from the thalamus and other sensory areas, and plays a crucial role in generating conscious perception of sensory stimuli. The other options, including the Brainstem/Thalamic, Caudal Medial Lemniscus, and Spinal Cord, are not the generators of A in this context.Rate this question:

-
Post-Central Gyrus
-
Pre-Central Gyrus
-

-
Brainstem
Correct Answer
A. Pre-Central GyrusExplanation
The Motor Cortex is responsible for initiating and controlling voluntary movements. It is located in the Pre-Central Gyrus, which is the primary motor area of the brain. This region is situated just in front of the Central Sulcus, which separates the frontal and parietal lobes. The Motor Cortex sends signals to the muscles of the body, allowing us to perform various movements. The Pre-Central Gyrus is specifically involved in the planning, coordination, and execution of voluntary movements.Rate this question:

A. MCA: Middle Cerebral ArteryExplanation
The correct answer is MCA: Middle Cerebral Artery. The Middle Cerebral Artery is one of the major arteries in the brain and supplies blood to the lateral surface of the cerebral hemisphere. It is responsible for providing oxygenated blood to important areas of the brain involved in sensory and motor functions, as well as language and speech. Understanding the different arteries in the brain is crucial for diagnosing and treating various neurological conditions.Rate this question:

The correct answer is CPc-CPi because it represents the difference between the central processing capacity (CPc) and the central processing input (CPi). This calculation helps to measure the efficiency or performance of the central processing unit (CPU) by comparing the amount of processing capacity available with the actual input being processed. By subtracting CPi from CPc, we can determine the utilization or effectiveness of the CPU in handling the given input.Rate this question:

The Motor & Sensory Cortices are divided by the
-
Post-Central Gyrus
-
Pre-Central Gyrus
-
Central Sulcus
-
Brainstem
Correct Answer
A. Central SulcusExplanation
The Motor & Sensory Cortices are divided by the Central Sulcus. The Central Sulcus is a prominent fold in the brain that separates the frontal lobe, which contains the Pre-Central Gyrus (motor cortex), from the parietal lobe, which contains the Post-Central Gyrus (sensory cortex). This division is important because it separates the areas of the brain responsible for motor functions and sensory processing, allowing for specialization and efficient processing of information. The Brainstem, on the other hand, is not involved in the division of the Motor & Sensory Cortices.Rate this question:

The correct answer is "Spinal Cord" because it is the part of the central nervous system that is responsible for transmitting sensory information from the body to the brain and motor information from the brain to the body. It plays a crucial role in coordinating reflexes and basic movements. The other options mentioned, such as the brainstem, thalamic, brachial plexus, and primary cortical somatosensory cortex, are also important components of the nervous system, but they are not directly responsible for the transmission of sensory and motor information like the spinal cord.Rate this question:

The brachial plexus is the correct answer because it is the nerve network that originates from the spinal cord and innervates the upper limb. It is responsible for transmitting sensory information from the arm and hand to the brain, making it the generator of the sensory signals in the upper limb. The primary cortical somatosensory cortex, caudal medial lemniscus, and spinal cord are all involved in the processing and transmission of sensory information, but they are not the direct generator of the signals in this case.Rate this question:

Lateral portion of the knee running behind the Fibular Head
Correct Answer
A. Between tendons of the Palmaris Longus & Flexor Carpi RadialisExplanation
The correct answer is "Between tendons of the Palmaris Longus & Flexor Carpi Radialis." This is because the median nerve stimulator is located in the forearm, and the Palmaris Longus and Flexor Carpi Radialis are two tendons that are present in the forearm. The median nerve runs between these tendons, making it the correct location for the nerve stimulator.Rate this question:

Correct Answer
A. Post-Central GyrusExplanation
The somatosensory cortex is responsible for processing sensory information from the body, including touch, temperature, and pain. It is located in the post-central gyrus, which is the area of the brain immediately behind the central sulcus. This location allows the somatosensory cortex to receive and interpret sensory signals from different parts of the body. The pre-central gyrus, on the other hand, houses the primary motor cortex responsible for controlling voluntary movements. The central sulcus is a prominent groove that separates the frontal and parietal lobes of the brain. The brainstem, while involved in many important functions, does not house the somatosensory cortex.Rate this question:

-
20-1kHz or -2dB
-
10-1kHz or -1dB
-

Correct Answer
A. 30-1kHz or -3dBExplanation
This answer indicates that the MN/Ulnar Bandpass has a frequency range of 30-1kHz and an attenuation of -3dB. This means that the bandpass allows frequencies within the range of 30-1kHz to pass through with minimal loss, while attenuating frequencies outside of this range. The -3dB attenuation indicates that the signal power is reduced by half at the cutoff frequencies of the bandpass.Rate this question:

-
Lateral portion of the knee running behind the Fibular Head
Correct Answer
A. Lateral portion of the knee running behind the Fibular HeadExplanation
The peroneal nerve stimulator is located in the lateral portion of the knee, running behind the fibular head. This is the correct answer because the peroneal nerve is a branch of the sciatic nerve that runs down the back of the leg and wraps around the fibular head. Stimulating this nerve can help with conditions such as foot drop, which is often caused by damage to the peroneal nerve. Placing the stimulator in this location allows for optimal stimulation of the nerve and effective treatment of the condition.Rate this question:
