P1 PHYSIOLOGY Flashcards
mention the 2 main types of sensations
1- cutaneous / tactile
2- proprioceptive
what is stereognosis
Recognition of the shape of objects
what is topognosis
Recognition of the texture of surfaces
spacing of 2 points is known as
2 point discrimination
self movement and body position from muscles and joints is known as
Proprioception
crude touch , pressure & temperature are taken to the brain by which tract
antero- lateral spinothalamic tract
fine touch , vibration & proprioception are taken to the brain by which tract
DCML
Process of converting the energy of a stimulus into electrical signal is known as
Somatosensory transduction
Regarding types of receptors , which type receives sensation on the neuron itself
Generator potential
Generator receptor is found in
free nerve endings & encapsulated nerve endings
Regarding types of receptors , when receptors are separate cells that when active they will transmit the electrical signal
receptor potential
mention the 2 types of summation
- spatial
- temporal
stimulation by several presynaptic neuronsnis which type of summation
Spatial summation
high frequency stimulation by 1 presynaptic neurons is which type of summation
temporal summation
a specific pathway that transmits information about a specific modality is known as
labelled line
