Somatic Nervous System Flashcards
________ is processed through a series of neurons
Sensory information
May result in conscious sensation or motor response
Sensory pathways
Are carried out by a series of neurons
Motor response
Transduce stimuli into an electrical charge interpreted by your brain that results in __________
Sensation
Allows receptors to become less sensitive to stimuli overtime
Adaptation
Can adapt quickly
Phasic receptors
Adapt slowly or not at all
Tonic receptors
Detects pain
Nociceptors
Detects pressure
Baroreceptors
Detects physical stimuli like pressure and vibration
Mechanoreceptors
Detects solute concentration in bodily fluids
Osmoreceptors
Stimuli from external environment
Exteroceptors
Stimuli from internal organs and tissues
Interceptor
Moving body parts
Proprio receptors
Found all over the body
General sense receptors
Found in the head
Special sense receptors
Is accomplished by photoreceptors of the eye
Vision
It is a chemical special sense
Taste gustation
What are the recognized tastes
Sweet sour bitter salty umami and fat
Where are the taste buds contained
Papillae
What replaces damaged taste receptors
Basal epithelial cells
What desolves molecules so that chemicals reach taste receptor cells
Saliva
It is detected when Na ions reach taste cell receptors
Salty
It is detected when H ions reach taste cell receptors
Sour
It is detected when glucose reach taste cell receptors
Sweet
Is detected by 23 different taste receptors but varies between individuals
Bitter
It is detected when L glutamate activates taste cell receptors
Umami
Detects deep pressure
Lamellated corpuscle
Detects light pressure
Tactile corpuscle
Detects stretching of skin
Bulbous corpuscle
These types of pain can share the same pathway
Somatic pain and visceral pain
Prevents further damage to tissues and cells of the body
Pain
Pain that originates inside blood vessels and internal organs
Visceral pain
Pain that covers other bodily tissues loke skin muscle and bone
Somatic pain
When the brain becomes confused on
where the origin of the pain is unclear
Referred pain
