Answer 1

1. Sleep-wakefulness cycle regulated in the supra chiasmatic nucleas (SCN) of the hypothalanus.

a. hypothalanus is not located in the occipital lobe. So this option is wrong.

b. hypothalanus is not located in the prefrontal gyrus. So this option is wrong.

c. hypothalanus is not present in medulla. So this option is wrong.

d. hypothalanus is present in the thalamus. So this is correct option.

e. hypothalanus is not present in the cerebellum. So this option is wrong..

The correct answer is- (C) Thalamus

2. a. Parietal lobe is associated with the the movement of the hand,arm eyes in response the stimulation of the somatosensory and visual inputs.So this ioption is wrong.

b. Temporal lobe is associated with the somatosensory function along with the laguage,memory,emotion etc. So this option is wrong

c.   The precentral gyrus is associated with primary motor function.This is correct option.

d. Pons is associated with the function like sleep,respiration,swallowing,urination etc.So this option is wrong,

e. The medulla is associated with the heart beating,sneezing, digestion etc. So this option is wrong.

The correct answer is-(C) Precentral gyrus

3. The motor tracts or the corticospinal tracts crosses each other at the mid-thoracic region.

a. Cerebellum is located just below the the occipital lobe.So this is not correct.

b. Hypothalamus is located in the mid brain region.So this is wrong option.

c. Tectum is the part of the mid brain.So this option is wrong.

d. Precental gyrus is located just after the frontal cortex ar in the middle part of the brain.So thios option is wrong.

e. Medulla is the end part of the brain located just above the pons,in the thoracic region of the spinal cord,below the cerebellum.So this option is correct.

The correct answer is-(E) Medulla

4. The Parasympathetic neurones responsible for releasing Acetylcholine on the target organ, where the Sympathetic is responsible for releasing Norepinephrine to stimulate the target organs.

So the correct answer is- False.

5. The cerebrum consists of two cerebral hemisphere which are pertially interconnect via the corpus collosum.

So the correct answer is- (B) Corpus collosum.

6. a. Frontal lobe is associated with-cognitive function,emotion,expression,problem solving,memory,language etc..So this option is wrong.

b. Occipital lobe mainly associateed with the function related with vision like the color,shape and size of the object etc. specially when drawing.

c. The corpora quadrigemina is associated with the reflex action of the vision and hearing. The stimuli of hearing does not integrated or proceessed here it only reflex the stimuli.So this option is wrong.

d. Insula is associated with the homeostatic function like the test,visceral sensation and the autonomic control.So this option is wrong.

e. Temporal lobe is associated with recognition of auditory stimuli.visual,and language recognition.So gearing is integrated here.So this option is correct.

The correct answer is-(E) Temporal lobe
