20. (a) loss of movement - any kind of injury in spinal cord can cause loss of sensation and movement and the injury can be of twotypes i.e, complete and incomplete depending on the damaged area of the spinal cord. If the motor pathways are affected by injury, it isliely that the person will suffer loss of movement ability.
21. (e) brain stem- it is the most primitive segment of our brain and consists of important parts like cerebellum, midbrain, medulla, pons and thalamus and hypothalamus.
22. (c) hypothalamus - it is the part of brain stem which reglates the motivated behaviours like sex drive, hunger, thirst, feelings of pleasure and other.
23. (d) right motor cortex - if a neurosurgeon stimulates a specific area of brain and individual's left finger twitches , it is likely that the right motor cortex is stimulated because if a person feels sensation of heat in his right leg, it would mean that somatosensory cortex is being stimulated.
24. (b) meninges, ventricles - meninges is known as the ineer protective coverage for the brain and ventricles are reffered to as the large fluid filled spaces in the brain.
