Medial-Superior colliculus - 23State the order of the three ossicles?Malleus Incus Stapes
- 24Vestibular and cochlear provide what functions?Balance and Hearing
- 25Tensor tympani and stapedius innervation?Trigeminal and facial
- 26Auditory nerves fibres past from the MGN to?Inferior colliculus
- 27Wernickes area, location and problems when theres a lesion?Temporal mainly and some parietal
receptive aphasia - 28Broca area, location and problems when theres a lesion?Frontal lobe just infront of the precentral gyrus
Expressive aphasia - 29Superior speech cortex relates to what area of the brain?SMA, when theres a lesion not many problems with speech
- 30Branches of the brachial plexus? What do they innervate?Musculataneous-biceps/brachialis
Median-Mostly forearm/some hand
Axillary-Deltoid
Radial-Post part of arm
Ulnar-Mostly hand/some forearm - 31Pathological signs of nerve damage?Wrist drop-Radial
Claw hand-Ulnar
Waiters tip-Axillary/musc
Loss of sensation over lateral palm/thumb-median - 327 branches of Lumbar plexus?Subcostal/Iliohypogastric/ilioingual
Genitofemoral/lateral cutaneous of thigh
Femoral/Obturator - 33More Medial Femoral or obturator? Innervate what?Obturator
Obturator innervates inner thigh(adductors)
Femoral anterior thigh - 34Name the nerves of Sacral plexus?Superior/inferior gluteal
Quadratus femoris/obturator internus
Sciatic
Posterior/peforating nerve of the thigh/pudendal - 35Three fibre types within the brain?Projection/Association/Commisural
- 36Five divisions of the association fibres?Extreme and external capsule
Cingulum
Superior/Inferior longitudinal fasciculus - 37Extreme and external separate what structures?Extreme-Insular cortex and claustraum
External-Claustaum and putamen - 38Comissural fibres can be divided into three sub sections?Anterior posterior and hippocampus
- 39The other main commissary fibre?Corpus callosum
- 40Projection fibres?Only the internal capsule
- 41What does the internal capsule separate?Lentiform nucleus (GP/putamen) and caudate nucleus
- 42Describe the circuit of Papez?Cingular gyrus to Hippocampus to Hypothalamus (mammillary bodies) to anterior nucleus of the thalamus to cinuglar gyrus to complete the circuit.
- 43Mammillary bodies contain nucleus of what part of the limbic system?Hypothalamus
- 44Amygdala receives inputs from what?Olfactory bulb
- 45Where is CSF produced?Choroid plexus (Lateral, 3rd and 4th ventricles)
- 46Describe the pathway the CSF takesLateral to the 3rd to 4th via the cerebral aqueduct then enters the sub arachnoid space then it enters the superior sagittal sinuses via the arachnoid granulations due to the pressure differences
- 47Describe the pattern of Gracile fascicles and cuneate fascicles?Above t6 there are both
Below t6 only gracile(medial to cuneate) - 48Pineal body produces what and where does it sit?Melatonin
Superior to the tectum - 49Describe the triangles above the obex?Hypoglossal medial to vagus
superior to hypoglossal and vagus is the vestibular area - 50Cancers that cause secondary tumours in the brain?Kidney/lung/skin/breast
