Answer 3

Adduction(medial rotation)

Question 4

Movements of eyeball

Answer 4

Elevation Moving pupil superiorly Superior rectus and inferior oblique
Depression Moving pupil inferiorly Inferior rectus and superior oblique
Abduction Moving pupil laterally Lateral rectus
Adduction Moving pupil medially Medial rectus
Medial rotation (intorsion) Rotating upper part of pupil medially towards nose Superior oblique
Lateral rotation (extorsion) Rotating upper part of pupil laterally towards temple. Inferior oblique

Question 5

Orbital muscles and innervation

Answer 5

Superior rectus,inferior rectus,medial rectus,inferior oblique - Oculomotor nerve
Lateral rectus. - Abducens nerve
Superior oblique. - Trochlear nerve

Question 6

(CPN is a branch of sciatic nerve)

Answer 6

Motor - Short head of the biceps femoris muscle(only motor branch arising from CPN)
Sensory - Skin over the upper lateral leg
Motor loss - Foot drop,Loss of dorsiflexion of ankle and foot eversion, weakness of foot inversion, loss of toe extension
