:Consider speech:
B:N:5
B:1:F:1
:speech is organised by bilateral centres in the parietal cortex
B:2:T:2
:speech can be arrested by stimulation of an area of the posterior
:temporal lobe
B:3:T:2
:the coordination of the muscles concerned with speech takes place in
:the frontal lobe
B:4:T:1
:the vowels are generated mainly in the larynx
B:5:T:2
:the high frequencies in speech are the result of movements of the
:tongue and lips
F:5
:Speech is organised unilaterally in the cerebral cortex, usually in
:the dominant side of the brain, and in the posterior lobe. Coordination
:of muscles of speech arises from Broca's area in the frontal lobe.
:Vowels are generated in the larynx, and the high frequencies of
:consonants are added by nose and mouth.

S:1
:Consider speech:
B:N:5
B:1:F:2
:the airflow during speech is under the control of the respiratory
:centre
B:2:T:2
:the activity of muscles that control the resonators in the larynx is
:regulated by the vagus nerve
B:3:T:2
:speech is controlled by an area of frontal cortex near the lower end
:of the precentral gyrus
B:4:F:1
:speech is controlled by pathways from both cerebral hemispheres
B:5:T:2
:motor aphasia is a condition in which the patient knows what he wants
:to say, and can write it down, but is unable to say it
F:8
:The regulation of air flow during speech is done by the higher centres
:of the nervous system which take over control of the respiratory
:muscles and the vagal efferents to the laryngeal muscles. Vocalization
:is controlled by a specialized large area of the motor cortex on the
:precentral gyrus, but speech is dependent on a 'speech centre' which is
:in the left hemisphere. Patients with R hemiplegia are usually unable to
:speak because the L hemisphere is affected where those with a L
:hemiplegia are usually able to speak normally.
