Peripheral Somatosensation Flashcards
1
Q
What are the types of Somatosensations?
A
- Position Sense
- Vibration Sense
- Touch
- Pain
- Temperature
2
Q
What are the Somatosensory Receptors?
A
- Mechanoreceptors
- Nociceptors
- Thermoreceptors
3
Q
Mechanoreceptors respond to
A
Mechanical stimuli like position, vibration + touch
4
Q
Describe Mechanoreceptors?
A
- Large diameter axons
- Thick myelin sheath
5
Q
What is the function of Nociceptors?
A
They detect pain
6
Q
Describe Nociceptors
A
- Bare nerve endings
- Small diameter axons
- Thin / no myelin sheath
7
Q
Thermoreceptors detect
A
Temperature changes
8
Q
Describe Thermoreceptors
A
- Bare nerve endings
- Small diameter axons
- Thin / no myelin sheath
9
Q
Muscle spindles can detect
A
Muscle stretch
10
Q
What gets stretched in muscle spindles?
A
Specialized fibers
11
Q
How do muscle spindles detect muscle stretch?
A
Their axons detect stretch and send information back into the CNS
12
Q
In the CNS, the neurons carrying information about the stimulus form an
A
Excitatory synapse
