Lecture 16 Eye movements

Which somatomotor neurons are responsible for eye movements?

the 2 cerebral regions for eye movement control.

Nuclei controlling/coordinating eye movements are

Which branch sends input to the vestibular nucleus?

Special movement features of the eyes

smooth pursuit is controlled by _______

saccades are controlled by

This muscle elevates the eye

This muscle depresses the eye

This muscle adducts the eye

This muscle abducts the eye

This muscle gives intorsion to the eye

This muscle gives extorsion to the eye

CN III innervates

CN IV innervates

CN VI innervates

CN III arises from _____ nuclei

Midbrain transverse cut, if you can see superior colliculi, the nueclei ventral to cerebral aqueduct are

The axons from oculomotor nuclei travels ventrally through the ________ and _______, exiting the midbrain between _________. Arteries surrounding its path: __________, ________.

Right dorsal to the oculomor nucleus, there are the _________, which are the origin for parasympathetic control of pupils.

The trochlear nerve arise from _________ in the midbrain at the level of ________. They are ______ to the medial longitudinal fasciculus and are at the ______ of the periaqueductal gray.

The abducens nerve arises in the _______ nucleus in the _____. They are wrapped around by the genu of _______ and are at the posterior border of _______.

The frontal eye fields (BA ___) control the ______ movements. There is also a supplementary eye field (BA ___) which initiate voluntaryFEF: BA8 eye movement.

When something is in your left visual field, the (left/right) FEF is activated by visual cortex to plan a saccade in the left.

Outline the saccade pathway starting from 'object of interest in left visual field'

The eye movements are also coordinated by the _______ of basal ganglia which relays from _______,______and_____ to speficy the 'what and where' of what we see.
