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

Nucleus pulposes is the central soft part of intervertebral disc representing remains of notochord (shock absorber).

Multiple choice

Which part of the human brain regulates respiration?

  1. Diencephalons

  2. Medulla

  3. Cerebellum

  4. Pons
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pons is the respiratory centre of the human body. It is part of the brainstem, and in humans, it lies between the midbrain (above) and the medulla oblongata (below) and in front of the cerebellum.

Multiple choice

Swallowing centre is situated in

  1. midbrain

  2. pons

  3. medulla

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

Swallowing centre is situated in medulla. It includes the dorsal motor nucleus of the vagus (DMV), the nucleus ambiguus of the vagus (NA) and the nucleus of the tractus solitarius (NTS).

Multiple choice

Brain stem contains

  1. cerebellum and medulla oblongata

  2. cerebellum, pons and medulla oblongata

  3. cerebellum and pons

  4. pons and medulla oblongata
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Brain stem contains pons and medulla oblongata. It has many basic functions including heart rate, breathing, sleeping and eating.

Multiple choice

Similar to human brain, the hindbrain of a bony fish is also made up of medulla oblongata and cerebellum. It coordinates movement, muscle tone, and balance. Fast-swimming bony fishes usually have an enlarged hindbrain.

  2. Software implementation

  3. Software analysis

  4. Software design

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

This form of transformation in software development process translates the users needs into system requirements and responsibilities.

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

Which lobe of brain is highly vulnerable to injury as it lies in front of the central cranium and any damage to this lobe causes problems like decreased problem solving ability and creativity alteration?

  1. Brain stem

  2. Hippocampus

  3. Cerebellum

  4. Pituitary

  5. Medulla oblongata
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Physically the brain of fish does not have a hippocampus region which is found in higher order vertebrae animals. The hippocampus is the part of the brain that is involved in memory forming, organising, and storing.

Multiple choice

  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.
