The anterior choroid plexus forms the roof of:
1 Diocoel
2 4th ventricle
3 Olfactory ventricle
4 Optocoel
Explanation:
A The cavity of diencephalon is called diocoel. Anterior choroid plexus is the folding in the roof of diocoel. It is highly vascularized and produce cerebrospinal fluid. Anterior choroid plexus is present on roof of diencephalon while posterior choroid plexus is present on roof of medulla oblongata. Both secrete CSF by the filtration of blood and also protects the brain from toxins.

Respiratory centre is present in
1 Cerebellum
2 Cerebrum
3 Medulla oblongata
4 Hypothalamus
Explanation:
C The hindbrain comprises pons, cerebellum and medulla oblongata. The medulla contains centers which control respiration, cardiovascular reflexes and gastric secretions. The respiratory centre is made up of three major respiratory groups of neurons two in the medulla and one in the pons. It is responsible for generating and maintaing the rhythm of respiration. Hence, respiratory centre is present in medulla and pons.

Which of the following is purely motor cranial nerve?
1 Olfactory
2 Optic
3 Abducens
4 Vagus
Explanation:
C Abducens is a motor nerve which controls the movements of the eyeball. Vagus, facial and trigeminal are mixed nerves. Abducens mainly motor nuclei laying under the floor of the fourth ventricle and pons. It is located in the superior to orbitral fissure. Purly motor cranial nerves are- (III) oculomotor (IV) Trochlear (VI) Abducent (XI) Accessory (XII) Hypoglossal Abducens is purely a motor nerve. It is also a smallest cranial nerve.
