Multiple choice zoology control and co-ordination in plants and animals the reflex action reflex action and reflex arc basic reflex action and reflex arc

Reflex arc located in the brain is called as___________

  1. Somatic reflex

  2. Cerebral reflex

  3. Autonomic reflex

  4. Both A and B
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  • The reflex actions which involve the brain are called as the cerebral reflex. The autonomic reflex is the one that involves inner organs and the somatic reflex is one that involves the muscles. 

Therefore, the correct answer is option B.

Multiple choice biology transport in mammals regulation of the activity of heart drug, tobacco and alcohol consumption community health and hygiene

Magnetoencephalography is useful in

  1. Study of activity of normal auditory area

  2. Depression

  3. Shocked patient

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Magnetoencephalography or MEG is a non-invasive technique for investigating human brain activity. It allows the measurement of the ongoing brain activity on a millisecond-by-millisecond basis and it shows where in the brain activity is produced. So, it is helpful in shocked patients.
So, the correct answer is option C.

Multiple choice

Which part of the brain is primarily responsible for language processing?

  1. Frontal lobe

  2. Parietal lobe

  3. Temporal lobe

  4. Occipital lobe
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The temporal lobe, particularly the left temporal lobe in most people, is the primary brain region responsible for language processing. It contains areas such as Wernicke's area and Broca's area, which are involved in language comprehension and production, respectively.

Multiple choice

Which language area of the brain is responsible for understanding the meaning of words?

  1. Wernicke's area

  2. Broca's area

  3. Angular gyrus

  4. Supramarginal gyrus
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Wernicke's area, located in the posterior superior temporal gyrus, is primarily responsible for language comprehension, including understanding the meaning of words and sentences.

Multiple choice

Which brain region is involved in the production of speech?

  1. Frontal lobe

  2. Parietal lobe

  3. Temporal lobe

  4. Occipital lobe
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The frontal lobe, particularly Broca's area in the left hemisphere, is involved in speech production. It is responsible for planning and executing the movements necessary for speaking.

Multiple choice

Which language area of the brain is responsible for the ability to name objects?

  1. Wernicke's area

  2. Broca's area

  3. Angular gyrus

  4. Supramarginal gyrus
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The angular gyrus, located at the junction of the parietal and temporal lobes, is involved in various language functions, including the ability to name objects.

Multiple choice

Which brain region is involved in the processing of syntax?

  1. Frontal lobe

  2. Parietal lobe

  3. Temporal lobe

  4. Occipital lobe
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The frontal lobe, particularly the left inferior frontal gyrus, is involved in the processing of syntax, which is the set of rules that govern the structure of sentences.

Multiple choice

Which language area of the brain is responsible for the ability to produce fluent speech?

  1. Wernicke's area

  2. Broca's area

  3. Angular gyrus

  4. Supramarginal gyrus
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Broca's area, located in the left inferior frontal gyrus, is primarily responsible for speech production, including the ability to produce fluent speech.

Multiple choice

Which brain region is involved in the processing of semantics?

  1. Frontal lobe

  2. Parietal lobe

  3. Temporal lobe

  4. Occipital lobe
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The temporal lobe, particularly the left temporal lobe, is involved in the processing of semantics, which is the meaning of words and sentences.

Multiple choice

Which ventricle is located in the midline of the brain, between the cerebral hemispheres?

  1. Lateral Ventricles

  2. Third Ventricle

  3. Fourth Ventricle
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The third ventricle is a narrow, slit-like ventricle located between the two lateral ventricles and connects them to the fourth ventricle.

Multiple choice

Which ventricle is located at the base of the brain, below the cerebellum?

  1. Lateral Ventricles

  2. Third Ventricle

  3. Fourth Ventricle
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The fourth ventricle is a diamond-shaped ventricle located at the base of the brain and connects to the central canal of the spinal cord.

Multiple choice

Which ventricle is responsible for producing the majority of the cerebrospinal fluid?

  1. Lateral Ventricles

  2. Third Ventricle

  3. Fourth Ventricle
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The lateral ventricles, located within the cerebral hemispheres, are the primary sites of cerebrospinal fluid production.

Multiple choice

Which structure connects the third and fourth ventricles?

  1. Foramen of Monro

  2. Aqueduct of Sylvius

  3. Foramen of Luschka
Reveal answer Fill a bubble to check yourself
