A coup-contracoup injury is clinically indicative of:
- A.
CVA
- B.
MS
- C.
Parkinson's
- D.
TBI
Correct Answer
D. TBIExplanation
A coup-contracoup injury refers to a type of traumatic brain injury (TBI) that occurs when there is a forceful impact to the head, causing the brain to move back and forth within the skull. The term "coup" refers to the initial impact site, while "contracoup" refers to the opposite side of the brain where the brain rebounds and hits the skull. Therefore, a coup-contracoup injury is a clear indication of a traumatic brain injury (TBI).Rate this question:

The Corpus Callosum is NOT an example of which of the following principles of neural organization:
- A.
Brain interconnectivity
- B.
Plasticity of the brain
- C.
Laterality of brain organization
- D.
Sensorimotor homunculus
Correct Answer
D. Sensorimotor homunculusExplanation
The sensorimotor homunculus is a representation of the body in the brain, where different body parts are mapped onto specific areas of the motor and sensory cortex. The Corpus Callosum, on the other hand, is a large bundle of nerve fibers that connects the two hemispheres of the brain, allowing for communication and coordination between them. Therefore, the Corpus Callosum is not an example of the sensorimotor homunculus principle of neural organization.Rate this question:

Which of the following indicates the slowness of movement?
- A.
Bradykinesia
- B.
Dystonia
- C.
Dyskinesia
- D.
Myoclonus
Correct Answer
A. BradykinesiaExplanation
Bradykinesia refers to the slowness of movement. It is a symptom commonly associated with Parkinson's disease, where individuals experience a significant reduction in their ability to initiate and complete voluntary movements. This slowness can affect various motor functions, such as walking, talking, and performing daily tasks. It is caused by the degeneration of dopamine-producing cells in the brain, leading to impaired communication between the brain and muscles.Rate this question:

The Brain's Architectural map is called: Brody's Area
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
The correct answer is False. The brain's architectural map is not called Brody's Area. This statement is incorrect as there is no such term or concept in neuroscience. The brain's architectural map refers to the organization and arrangement of different regions and structures within the brain, such as the cerebral cortex, hippocampus, and cerebellum.Rate this question:

The PNS is comprised of:
- A.
Somatic NS, Autonomic NS, Brain, Symapathetic system
- B.
Somatic NS, Spinal Cord, Sympathetic system, Autonomic system
- C.
Somatic NS, Autonomic NS, Medulla Oblongata, Parasympathetic system
- D.
Somatic NS, Autonomic NS, Sympathetic System, Parasympathetic system
Correct Answer
D. Somatic NS, Autonomic NS, Sympathetic System, Parasympathetic systemExplanation
The correct answer is Somatic NS, Autonomic NS, Sympathetic System, Parasympathetic system. This answer is correct because it includes all the components of the Peripheral Nervous System (PNS). The PNS is divided into the Somatic NS, which controls voluntary movements, and the Autonomic NS, which controls involuntary functions. The Autonomic NS is further divided into the Sympathetic System, which prepares the body for "fight or flight" responses, and the Parasympathetic system, which promotes "rest and digest" responses. Therefore, this answer includes all the correct components of the PNS.Rate this question:

The Prosencephalon, Mesencephalon, Rhombencephalon are the three major vesicles of the ________ brain
- A.
Embryonic
- B.
Midcephalic
- C.
Flexure
- D.
Pontine
Correct Answer
A. EmbryonicExplanation
The correct answer is embryonic because the question is asking about the three major vesicles of the embryonic brain. The Prosencephalon, Mesencephalon, and Rhombencephalon are the three primary divisions of the embryonic brain.Rate this question:

The Basil Ganglia and the Diencephalon are part of the _________
- A.
Cerebrum
- B.
Basil ganglia
- C.
Cerebellum
- D.
Spinal cord
Correct Answer
A. CerebrumExplanation
The Basil Ganglia and the Diencephalon are part of the cerebrum. The cerebrum is the largest part of the brain and is responsible for higher cognitive functions such as thinking, memory, and voluntary movements. The Basil Ganglia and the Diencephalon are substructures within the cerebrum that play important roles in motor control, coordination, and regulation of emotions and behaviors.Rate this question:

The Insular Lobe of the Cerebral cortex is within the depth of the __________
- A.
Lateral fissue
- B.
Central fissure
- C.
Hippocampus
- D.
Corpus Callosum
Correct Answer
A. Lateral fissueExplanation
The Insular Lobe of the Cerebral cortex is within the depth of the lateral fissure. The lateral fissure, also known as the Sylvian fissure, is a prominent anatomical landmark in the brain that separates the frontal and parietal lobes from the temporal lobe. The insular lobe is located deep within this fissure, tucked away beneath the frontal, parietal, and temporal lobes. It plays a role in various functions such as emotion, self-awareness, and perception of taste.Rate this question:

Sensory Fibers are Descending
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Sensory fibers are ascending, not descending. Sensory fibers transmit information from the peripheral nervous system to the central nervous system, which involves carrying signals upwards towards the brain. Therefore, the correct answer is false.Rate this question:

The Cerebral Cortex, basal ganglia, limbic system, and lateral ventricles are part of the:
- A.
Telencephalon
- B.
Diencephalong
- C.
Mylencephalon
- D.
Rhombencephalon
Correct Answer
A. TelencephalonExplanation
The correct answer is telencephalon. The telencephalon is the largest part of the brain and is responsible for higher cognitive functions such as thinking, memory, and language. It includes the cerebral cortex, which is involved in sensory perception and motor control, as well as the basal ganglia, which are involved in movement and reward. The limbic system, which is involved in emotions and memory, is also part of the telencephalon. The lateral ventricles, which are fluid-filled spaces in the brain, are located within the telencephalon.Rate this question:

The basis pedunculi, substantia nigra, and red nucleus are part of the:
- A.
Pons
- B.
Midbrain
- C.
Corticospinal bulb
- D.
Cerebellum
Correct Answer
B. MidbrainExplanation
The basis pedunculi, substantia nigra, and red nucleus are all structures that are located in the midbrain. The midbrain is a small region of the brainstem that is responsible for various functions such as motor control, auditory and visual processing, and regulation of sleep and wakefulness. These structures play important roles in motor control and coordination, and their location in the midbrain suggests that they are part of this region. Therefore, the correct answer is midbrain.Rate this question:

The primary and secondary visual cortex are associated with which lobe?
- A.
Frontal
- B.
Parietal
- C.
Occipital
- D.
Temporal
Correct Answer
C. OccipitalExplanation
The primary and secondary visual cortex are associated with the occipital lobe. This is because the occipital lobe is responsible for processing visual information received from the eyes. It plays a crucial role in visual perception, including the recognition of shapes, colors, and movement. The primary visual cortex, located in the occipital lobe, receives visual input from the eyes and processes basic visual features. The secondary visual cortex, also in the occipital lobe, further analyzes and interprets the visual information.Rate this question:

Which of the following has the function of: regulating emotion to visceral/vegetative functions (feeding, fleeing, fighting, mating) and values and decisions about perceptions and feelings?
- A.
Corpus Callosum
- B.
Limbic Lobe
- C.
Insular Gyrus
- D.
Hypothalamum
Correct Answer
B. Limbic LobeExplanation
The limbic lobe is responsible for regulating emotions and controlling visceral or vegetative functions such as feeding, fleeing, fighting, and mating. It also plays a role in decision-making and evaluating perceptions and feelings.Rate this question:
