Palsy of Abducens nerve causes which of the following?
- Horizontal diplopia
- Vertical diplopia
- Unopposed abduction of the eye
Horizontal Diplopia
Strabismus vs Amblyopia
Strabismus is squint, andamblyopia is lazy eye (a condition caused by strabismus)
THE EAR
Loss of percieving system/inner ear results in….
SENSORINEURAL hearingloss
- Otitis externa (most common bacterial cause is calledstaph aureus)
- Otitis media (aka glue ear, most common bacterialcause is called staph aureus)
- Meniere’s-too much endolymph-> increased pressureon the nerve (vertigo, tinnitus, SNHL
What is Dysmertria?
is a lack of coordination of movementtypified by the undershoot or overshoot of intendedposition witha limb
Dysarthria
:slurred speech
Dysdiadochokinesia
poorly performed repetitivemovements
Fasciculations
Visible twitching of a muscle due todamaged alpha motor neuron
Spasticity
increased muscle tone/stiffness.
Apraxia
impaired selection of movement (cannotexecute something they understand
Ataxia:
lack of coordination.
- Central(due to damage to the cerebellum)
- Sensory(due to a lack of sensory input)
Friedrich’s Ataxia:
AR Triple repeat hereditary disorder(GAA)
Anterior Cord Injury
loss of motorfunction,crude touch, temp and painsensation below the level of the lesion(affects the corticospinal and spinothalamictracts)
Posterior Cord Injury
:loss of fine touch,vibration and proprioception below level ofinjury (affects the dorsal columns
Central cord injury:affects
the corticospinaltracts and the lateral spinothalamic tract.Loss of pain and temperature, andweakness
What is cerebral palsy?
When there is an overall deficit in motorfunction due to lack of oxygen during or near tochildbirth which subsequently causes brain damage tothe neonate
