Dentate-planning/timing/skill - lateral hemisphere

Globose & Emboliform-posture/ muscle tone/ walking- paravermis

Fastigial-eye movement & balance- vermis

Question 11

what is the function of the

vermis

paravermis

lateral hemisphere

Answer 11

vermis- balance (important to gait)

paravermis- limb coordination

lateral hemisphere- planning and exucuding of coordinate movements
