Besides the skull, list at least two () ways in which the central nervous system is protected.

Answer 1

Answer: Damage to medulla oblongata has more death probability because it is the centre of many visceral functions. 6. a) Gateway to the cerebrum is Thalamus. b) Ensures Coordinated motor control and balance is the cerebellum. ic). Produce automatic behaviour nec survival is hypothalamus d). Executive e). Visceral functions is cerebrum command center is Brain stem.

9. Two cerebral hemispheres are connecte by coopus callosum. Left hemisphere specializes in fine motor activities. - 20. functions of cerebrospinal fluid : a). It protects the brain from injury and infections. 6). Provide certain nutrients to brain. CSF is present in the ventricles of brain and flow from there to above the brain and to the spinal cord 12. CNS is protected by: • meninges • Csf
