Peripheral Nervous System 1 Flashcards
Consciously interpreting the world around you using your sensory system is known as?
Perception
Interpretation can either go the __________ or ________
A) Spinal cord
Or
B) Brain stem and upwards
The energy form of stimulus is called
Modality
Every receptor has its own modality (energy form)
Yes or No
Yes
What is the energy form converted into?
It’s converted into Action potential
Touch receptors will have __________ as it’s energy form (modality)
Touch
When light photons are converted into sensory modality, it’s called
Transduction
The change from one modality to modality is called
Transduction
The conversion of one energy form to another energy form is called
Transduction
Light made into an image by the eye is what type of transduction
Visual transduction
How does the conversion happen/how is the message produce?
It’s produces thru action potential, which is how they get to the CNS.
Action potential can take 2 distinct forms of generation?
- Receptor potential
- Generator potential
What’s helps to avoid wastage of energy?
Receptor adaptation
The receptor adaptation can either be ________ or _________z
Slow or rapid
2 major types of receptor adaptation?
- Tonic adaptation
- Phasic adaptation
What type of adaptation fires immediately and then slowly adapt to maintain homeostasis?
Tonic Adaptation
What type of adaptation is seen in muscle & joint receptor and pressure receptors?
Tonic Adaptation
What type of adaptation is fast and rapid?
Phasic adaptation
The type of adaptation where homeostasis is not disturbed is called?
Phasic adaptation
Touch receptors/smell receptor/tactile responses/olfactory receptors are all examples of what kind of adaptation?
Phasic adaptation
The adaptation working to maintain homeostasis is
Tonic Adaptation
What’s always follow a pathway?
Receptors
Which neuron is the first neuron in the somatosensory pathway?
Afferent Neurons
Which is the first order Neurons?
Afferent Neurons
