Nervous System Physiology Questions

Multiple choice

Which among the following areas of the cortex does not receive sensory information directly but via. the primary motor or sensory cortices in the brain?

  1. Hippocampus

  2. Limbic system

  3. Sensory areas

  4. Association areas

  5. Motor areas
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Association areas do not receive sensory information directly, but via the primary motor or sensory cortices in the brain.Thier main function is to produce a meaningful perceptual experience of the world, and enable us to interact effectively, and support abstract thinking and language.  

Multiple choice

Mr. Verma met with a severe road accident and became very poor in grammar and pronunciation. Which part of her brain must have affected in the accident?

  1. Hypothalamus

  2. Wernicke's area

  3. Broca's area

  4. Pons

  5. Brain stem
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Broca's area is the part of the brain, which is on the front left side of the cortex of the brain and is responsible for not only speech production but also language comprehension, language compression and controls facial neurons.

Multiple choice

Wernicke's area is associated with ___________.

  1. speech comprehension

  2. balance of the body

  3. reflexes

  4. production of speech

  5. perception of stimuli
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Wernicke's area is associated with the processing of words being heard, spoken or language inputs. Individuals having lesions in Wernicke's area can speak, but their speech is frequently incoherent and makes no sense.

Multiple choice

Which among the following can be excluded from the functions of cerebellum?

  1. Maintenance of balance and posture

  2. Coordination of voluntary movements

  3. Motor learning

  4. Cognitive functions

  5. Maintenance of normal heart beat rate
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

Medulla oblongata  is the caudal most part of the brain stem and is responsible for maintaining vital body functions, such as breathing and heart beat rates.

Multiple choice

A 63 year old woman is unsteady and walks with a high stepping gait in a dark room. The most likely neuroanatomical basis for her problem is

  1. frontal lobes

  2. somatic system

  3. spinal cord

  4. cerebellum

  5. spinal nerves
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Proprioceptive loss (Romberg's sign, loss of balance in the dark) could be due to a peripheral neuropathy or a disease of the dorsal columns of the spinal cord. However, the presence of increased tone in the lower limbs suggests that the spinal cord is the site of disease here. 

Multiple choice

Which among the following parts of brain provides remarkable distinctions between humans and other animals?

  1. Cerebral cortex

  2. The limbic system

  3. The cerebellum

  4. The thalamus

  5. The spinal cord
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The cerebral cortex is the portion of the brain that provides remarkable distinctions between humans and other animals. It enables humans not only to receive and interpret all kinds of sensory information, such as color, odor, taste, and sound, but also to remember, analyze, interpret, make decisions, and performs a host of other higher brain functions.

Multiple choice

The pons pretends as a bridge between the medulla and other parts of human brain. Which of the following functions is regulated by pons of the brain?

  1. Declarative and episodic memory

  2. Maintains body balance

  3. Memmory and speech

  4. Fight or flight response

  5. Sleep and arousal
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

The pons is a section of the brain lying above the medulla oblongata. It plays important role in arousal, sleep, carrying sensory information between cerebrum and cerebellum, and helping control of autonomic functions.
