Questions Related to life processes: control and coordination
Different portions of the brain are responsible for specific functions.
-
True
-
False
Different regions of the brain are responsible for specific functions. For example, the medulla oblongata is responsible for regulating heart beat and many other involuntary actions. The Broca region is responsible for speech and language etc. So, the correct answer is option A.
-
True
-
False
-
The spinal cord serves as a conduit for signals between the brain and the rest of the body. It also controls simple musculoskeletal reflexes without input from the brain.
-
The brain is responsible for integrating sensory information and coordinating body function, both consciously and unconsciously.
Brains can work 24 hours a day with no rest.
-
True
-
False
The largest number of neurons are found in
-
Brain
-
Retina
-
Spinal cord
-
Tongue
Retina forms the innermost layer of eyeball and mainly contains rods and cones, the photoreceptors, along with nerve fibres.
The appetite and satiety centres in the brain of man are located in the region of the
-
Cerebral hemisphere
-
Cerebellum
-
Medulla oblongata

Power of regeneration is lowest in
-
Brain cell
-
Liver cell
-
Bone cell
-
Muscle cell
Brain cells remain in the beginning stage of interphase of cell reproduction for their life, and never divide, and instead develop by forming new synapses with other neurons. They lack cellular machinery for cell division. So, the correct answer is option A.
Deficiency of oxygen affects mainly the
-
Brain
-
Skin
-
Kidney
-
Intestine
Brain cells are extremely sensitive to a lack of oxygen. Some brain cells start dying less than 5 minutes after their oxygen supply disappears. As a result, brain hypoxia can rapidly cause severe brain damage or death.
Name which part is often referred to as the emotional brain?
-
Cerebellum
-
Cerebrum
-
Central Nervous System
-
Limbic System
- The limbic system often referred to as the "emotional brain", is found buried within the cerebrum.
- Like the cerebellum, evolutionarily the structure is rather old. This system contains the thalamus, hypothalamus, amygdala, and hippocampus.
Cerebral cortex is divided into sections like_____________
-
Left and right lobe
-
Thalamus and hypothalamus
-
Frontal, parietal, occipital and temporal lobes
-
None of these
The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action. The cerebral cortex is divided into four sections, called "lobes". The frontal lobe, parietal lobe, occipital lobe, and temporal lobe.
Which part of the brain converts short term memory to permanent memory?
-
Amygdala
-
Thalamus
-
Mid-brain
-
Hippocampus
- Hippocampus is the portion of the cerebral hemispheres in basal medial part of the temporal lobe.
- This part of the brain is important for learning and memory, for converting short term memory to more permanent memory and for recalling spatial relationships in the world about us.
