cranial nerves - facts

By Pratyush kumar

Cranial nerves – facts

CN which is the smallest -- olfactory n.
CN which enters cerebrum directly - olfactory nerve

CN with longest intracranial (subarachnoid) course -- trochlear n
CN which emerges posterior to brain stem- trochlear nerve
CN with dorsal exit -- trochlear n.
CN which is the largest and thickest -- trigeminal n.
CN which is largest -- trigeminal nerve
CN with longest extracranial course --vagus n.
CN having longest intraosseous course -- facial nerve
CN with longest ( intradural )course - abducent nerve
CN passing through cavernous sinus -- abducent nerve
CN involved in raised intracranial tension -- abducent nerve 
Abducent nerve has the longest intra-cranial INTRADURAL course!!
Thickest nerve is SCIATIC nerve
Thickest cutaneous nerve is GREATER OCCIPITAL nerve
Labourer’s nerve-median nerve
Dentist’s nerve-inferior alveolar nerve
Alderman’s nerve-auricular branch of vagus nerve
Nerve of laterjet-largest gastric branch of vagus nerve

orthopaedics viva

By Pratyush kumar

 I am going to write about my ortho viva..it was very interesting one..
so questions were ranging from peripheral nerve injury to fracture dislocation and pathology of bone and joints.
WHILE answering any question REGARDING MANAGEMENT one should be very particular in mentioning 
INVESTIGATIONS first and then TREATMENT..{examiners look for it}

my first question was on radial nerve injury , its course ..
injury at the origin of radial nerve will paralyse all the muscles
injury at the level of radial groove{Saturday night palsy} ,triceps muscle escapes..
radial nerve causes extension so injury to it causes wrist drop{ unable to extend at the level of wrist}
interossei are also supplied by ulnar nerve so it escapes..
brachioradialis is supplied by the nerve before it divides into superficial and deep branches so testing the muscle will tell the level of injury..
injury to posterior interosseous branch cause wrist drop.. but extensor carpi radialis longus may escape  
then the next question was on ANGULAR DEFORMITY at the knee joint.
genu-knee , coxa -hip , cubitus -elbow
so genu valgum and genu varum are the angular deformity..to know the severity we can measure inter malleolar and inter condylar distance. Q angle is also diagnostic.
