The hindbrain comprises pons, cerebellum and medulla. Pons consists of fibre tracts that interconnect different regions of the brain. Cerebellum has very convoluted surface in order to provide the additional space for more neurons, regulates posture and balance. The medulla contains centres which control respiration, cardiovascular reflexes and gastric secretions. Hypothalamus contains several groups of neurosecretory cells, which secrete hormones called hypothalamic hormones.
Given below are two statements:
Statement I: The cerebral hemispheres are connected by nerve tract known as corpus callosum.
Statement II: The brain stem consists of the medulla oblongata, pons and cerebrum.
In the light of the above statements, choose the most appropriate answer from the options given below: [2024]
Both Statement I and Statement II are correct.
Both Statement I and Statement II are incorrect.
Statement I is correct but Statement II is incorrect.
Statement I is incorrect but Statement II is correct.

Mid brain, Pons and medulla oblongata are three major regions that make up the brain stem. Cerebrum is the part of forebrain.
Brainstem of human brain consists of [2023]
Mid-brain, Pons and Medulla oblongata
Forebrain, Cerebellum and Pons
Thalamus, Hypothalamus and Corpora quadrigemina
Amygdala, Hippocampus and Corpus callosum
(1)
Three major regions make up the brainstem – mid brain, pons and medulla oblongata. Brainstem forms the connections between the brain and spinal cord.
The parts of human brain that helps in regulation of sexual behaviour, expression of excitement, pleasure, rage, fear etc. are: [2023]
Brain stem & epithalamus
Corpus callosum and thalamus
Limbic system & hypothalamus
Corpora quadrigemina & hippocampus
(3)
Limbic system or limbic lobe along with hypothalamus is involved in the regulation of sexual behaviour, expression of emotional reactions, such as excitement, pleasure, rage, fear, motivation, etc.
Which part of the brain is responsible for thermoregulation? [2019]
Medulla oblongata
Cerebrum
Hypothalamus
Corpus callosum
(3)
Hypothalamus is thermoregulatory centre. Hence it is called “thermostat” of the body. It keeps body temperature at roughly 37°C by means of a complex thermostat system.
Which of the following structures or regions is incorrectly paired with its functions? [2018]
Medulla oblongata : Controls respiration and cardiovascular reflexes
Limbic system : Consists of fibre tracts that interconnect different regions of brain, controls movement
Hypothalamus : Production of releasing hormones and regulation of temperature, hunger and thirst
Corpus callosum : Band of fibers connecting left and right cerebral hemispheres
(2)
Certain components of the cerebrum and diencephalon constitute the limbic system. It is sometimes called the emotional brain because it controls emotional behaviour expressed in the form of joy, sorrow, fear, fight, friendship, liking and disliking. It also controls food habits and sex behaviours necessary for survival of the individual.
Which of the following regions of the brain is incorrectly paired with its function? [2015]
Corpus callosum - communication between the left and right cerebral cortices
Cerebrum - calculation and contemplation
Medulla oblongata - homeostatic control
Cerebellum - language comprehension
(4)
Language comprehension is a function of cerebrum. Cerebellum coordinates and controls rapid muscular activities such as running, typing, etc. Although it does not initiate such voluntary movements, but it is an important centre for coordinating movements and for controlling posture and balance. Cerebellum’s function is almost exclusively motor; but it is also implicated in some forms of learning.
Injury localized to the hypothalamus would most likely disrupt [2014]
short-term memory
co-ordination during locomotion
executive functions, such as decision making
regulation of body temperature
(4)
Hypothalamus lies at the base of the thalamus. It provides anatomical connection between the nervous and endocrine systems by its relationship to the pituitary gland. Hypothalamus is thermoregulatory centre. Hence, it is called “thermostat” of the body. It keeps body temperature at roughly 37°C by means of a complex thermostat system. Any localised injury to hypothalamus will, hence, disrupt regulation of body temperature.
