Final Exam Review: Block XC, Module X8 Flashcards
(28 cards)
Signal Transduction is the process of…
Converting sensory stimulus into action potentials
Tonic receptors adapt X
slowly
Phasic receptors adapt X
quickly
Would the receptors that respond to the burning sensation of storng chemicals on your skin be tonic of phasic ?
Tonic
Would the receptors that respond to the smell of baked goods be tonic or phasic?
Phasic
Smaller receptor field are X sensitive
more
Larger receptive fields are X sensitive
less
Lateral inhibition helps X the stimulus by X X pathways
Localize, inhibiting, neighboring
Stimulus of pain and itch are detected by this sensory neuron.
Nociceptors
Stimulus of temperature are detected by this type of receptor.
Thermoceptors
Will a nociceptor attached to a large diamiter Mylinated primairy sensory neuron be tonic or phasic?
Phasic
Will a nociceptor attached to a small diamiter unmylinated primary sensory neuron by tonic or phasic?
Phasic
Will a professional pianist have a larger area in the brian detticated to touch and sound.
Most likely yes
Just because a sensory region of the body has been lost, (amputated for exemple) does this mean that sensation in this area of the body will be lost imediatly?
Overtime yes, but not imediatly the area of the brian associate with this sensory region will fade slowly
What is the idea of labeled line coding?
Idea that groups of sensory neurons will be associated to particular regions of the brain
In the sensory pathway for somatic sensation, sensory information from the primary sensory neuron will be relocated to…
The CNS
(medula or spinal cord)
In the sensory pathway for somatic sensation, sensory information from the secondairy sensory neuron will be relayed to…
The Thalamus
(oposite the side of stimulus location)
In the sensory pathway for somatic sensation, sensory information from the tertiary sensory nuron will be relayed to…
somatosensory cortex
(region of the brain dedicated to processing sensory information)
sensory pathways acosiated with pain will synapes where?
In the spinal cord
Sensory pathways accosiated with movement and fine touch will synapes where?
In the medulla
Spinothalamic pathways will synapes where?
In the spine
Lemniscous pathways will synapes where?
In the medulla
X allows use to sense thousands of different odors
Population coding
Sour taste receptor bind with X molecule
H+
