What is the origin of tectospinal tract?
It arises from superior colliculus of midbrain.
What is Benedict's syndrome?
complete or partial oculomotor nerve palsy; and contralateral tremor (due to damage of rubrospinal tracts.)
What is the origin of olivospinal tract?
It arises from lateral vestibular nuclei in the pons
What are the sites of origin of the pyramidal tract?
the pyramidal cells in layer 5 of areas 4, 6 ,3-1&2
What's Tuberculosis?
TB is caused by infection with the bacterium Mycobacterium tuberculosis Sinusitis is a symptom which manifests usually with upper respiratory tract infections.Common cold is a upper respiratory tract infection of viral origin, usually caused by rhinovirus
