(30 cards)
Rotation of the distal extension of a RPD mainly occurs in what type of supported denture
tooth tissue supported RPD
What medication is most effective against treating severe depression
TCA
what happens to the eye lens to enable distant vision
ciliary muscles contract to stretch the lens
what happens to the eye lens to enable close vision
ciliary muscles relax to bulge the lens
what type of cell is responsible for mediating type 4 hypersensitivity
helper T cells
what is code 011
- comprehensive oral examination of the dentition, mouth and associated structures
- for new patients, established patients who have had a significant change in health condition or established patients who have been absent for 2 or more years
What is code 012
- Periodic Oral examination
- For returning patients which has been less than 2 years
What is code 013
- Oral examination limited
- When patient comes in for a specific issue or complaint
What is the function of the prefrontal cortex
Planning and organisation of goal directed behaviour
What is the function of premotor cortex
preparation and execution of complex movements
What is the function of the primary motor cortex
direct influence over muscle groups
What are the 2 primary motor pathways
- corticospinal tract
- corticobulbar tract
what is a corticospinal tract
- descending motor tract that controls voluntary movement of the limbs and trunk
- also important for fine motor skills (hand movement)
- originates in the primary motor cortex and synapses with lower motor neurons in the anterior horn of the spinal cord
- majority decussate to innervate contralateral lower motor neurons in spinal cord
What are corticobulbar tracts
- descending motor tract that controls voluntary movements of the face, head, and neck by influencing cranial nerves
- controls muscles of facial expression, mastication, swallowing and speech
- originates int he primary motor cortex and terminates int he motor nuclei of cranial nerves in the brainstem
- terminate on cranial nerve nuclei in medulla - principally 5,7,9,10,12. Unlike CST pathway inputs to cranial nerves are from both cortices
what are pyramidal tracts
direct motor pathways that originate in the cerebral cortex and control voluntary, fine motor movement
e.g.
- corticospinal tract,
- corticobulbar tract
What are extrapyramidal tracts
Indirect motor pathways that originate in subcortical areas (not the cortex) and control involuntary , automatic and postural movements
which sensory pathway is responsible for the movement of your head neck and facial muscles
spinothalamic tract
what vertebra does the sympathetic nervous system come from
T1-T12 and L1-L2/3
where do the parasympathetic nervous system outflow from
Cranial: comes from CN 3,7,9,10,
Sacral S2-S4
Describe the anterior lateral spinothalamic pathway
- Ascending pathway
- Pain, temperature and course touch
- Sensations we have difficulty in precisely localising
- Involved in emotional aspects of perception
- periphery
- dorsal horn
- immediate decussation
- thalamus
- somatosensory
- sensation
where is erythropoietin produced from
Kidney
what is phospholipase and what inhibits it
enzyme which releases arachidonic acid which is a precursor for
- prostaglandins
- leukotrienes
- thromboxanes
initiating the production of key inflammatory mediators
inhibited by corticosteroids
what is the recommended chlorohexidine concentration for long term use (>2 weeks)
0.2%
What is the visual pathway
The visual pathway is the route by which visual signals from the eye are transmitted to the primary visual cortex in the brain for processing and perception
- retina
- optic nerve
- optic chiasm
- optic tract
- optic radiations
- LGN (lateral geniculate nucleus)
- primary visual cortex
