convergence of eyes in primary position
also lateral diplopia-diplopia on walking down the stairs
where does the aorta pass through the diaphragm
T12
what signs would someone with erbs palsy present with
loss of abduction, flexion and lateral rotation of arm, producing a waiters tip posture
what does an upper motor neuron lesion of the facial nerve cause

what does a lower motor lesion of facial nerve cause
paralysis of ipsilateral side of the face
what could damage to the sciatic nerve cause
foot drop
inability to extend halluces longus
loss of sensation to posterior aspect of thigh and leg
how do you calculate cerebral perfusion pressure
MAP-ICP

claw hand (MCP joints extended and IP joints flexed)
loss of sensation over medial aspect of forearm and hand
horners syndrome
loss of flexors of the wrist
what are the features of essential tremor

where are Golgi tendon organs located and what do they prevent against
monitor changes in muscle tension to prevent from overload, located at the junction between tendon and muscle
describe typical features of LMN lesions
wasting and fasciculations
reduced/absent reflexes
how can you tell the difference in primary muscle disease and LMN
symmetrical loss and reflexes lost later in LMN lesions than neuropathies and there is no sensory loss with LMN lesions
