Q

Responsible for central vision

A

Macula in occipital pole

  • PCA supplies occipital lobe, responsible for perceiving LATERAL visual field in both eyes
  • Meyer’s loop is the INFERIOR division of optic radiations as they pass through the temporal lobe. Supplied by MCA.
27
Q

Identify presentation of a CN 7 lesion (5)

A

1 dec taste sensation anterior 2/3 IPSI tongue - chorda tympani
2 retroauricular pain - sensory to small area of IPSI ear
3 IPSI facial paralysis - motor to muscles of facial expression
4 inc sensitivity to noise IPSI ear - NS to STAPEDIUS ms which normally prevents excessive movement of stapes
5 dryness IPSI eye and mouth - PNS to IPSI lacrimal gland, submandibular and sublingual gland

28
Q

Basal ganglia direct vs indirect pathway

Which is inhibitory?

A

INdirect pathway : INhibits movement

D1 receptor : D1rect pathway

  • D1rect pathway : D1 receptor : facilitates movement
  • INdirect pathway : INhibits movement : D2 receptor
  • Lentiform nucleus = put amen + globus pallidus
  • Striatum = putamen (motor) + caudate (cognitive)
  • recall nigroStriatal pathway
