Sensory Integration FoR Flashcards
Grey Matter-
Cell bodies of neurons
White Matter-
Axons (insulated wires)
Efferent = ___ signals
motor
Afferent = ___ signals
sensory
Lateral Spinothalamic Tract senses ___ and ____
Pain and temperature
Ventral Corticospinal Tract (Anterior) Carries ___
motor information of all the muscles that don’t involve the limbs
Anterior Spinothalamic Tract senses ____
Crude touch sensation
Dorsal Column Medial Lemniscus Pathway/ Posterior Column Conveys the senses of.
fine touch & proprioception to the brain
In the dorsal column medial leminscus pathway, information is taken in and ascends to the brainstem Also know as the ____ system
Discriminative
Serotonin is known as the ____ neurotransmitter
Workhorse
Directly and indirectly influences the majority of brain cells.
Function of serotonin
Influences mood, appetite, sexual desire/function, sleep, memory/learning
Which neurotransmitter directly and indirectly influences the majority of brain cells?
Serotonin
Dopamine plays a role in
movement, memory, pleasurable, behavior, cognition, sleep, mood & learning
The Proprioceptive Sense – ____ pressure (more ____ feedback)
deep
static
· The Vestibular Sense – sense of _____ (feedback in relation to ____)
movement
gravity
The _____ system is easiest to detect of all sensory dysfunction because it gets the most abuse
tactile
Which system in the primary protective system?
Tactile
Which two systems make up the somatosensory system?
proprioceptive and tactile
Which system has receptors present in all skeletal muscles?
The proprioceptive system
Information from the proprioceptive is carried in the
dorsal column-medial lemniscal system (Discriminative)
The propriocepive system · Receives information from:
1) Vestibular pathways
2) Cortex
The proprioceptive system · Sends info back to:
1) Brain Stem
2) Cerebellum
3) Thalamus
4) Cortex
Functions of the otoliths in the vestibular system?
Linear, positioning, static, postural holding responses
Functions of the utricle in the vestibular system?
Sensitive to motions in the horizontal plane-linear
Acceleration – forward or side-to-side
Functions of the saccules in the vestibular system?
o Sensitive to motions in the vertical plane
o up and down and tilt forward and back
The semicircular Canal System is sensitive to?
· Sensitive to rotary movement – angular, changing fast movement.
The semicircular canal system sends information to the _____ where the are _____…Connections to eye movement
upper brainstem
Superior Vestibular Nuclei
The _____ get the information from the otoliths, utricle, and saccule
inferior vestibular nuclei
Antigravity muscles of the neck and upper trunk get information via the
medial and lateral vestibulospinal tracts (related to decreased muscle tone with vestibular problems)
Cerebellum- Allows for movement through
inhibition!!!
Thalamus- acts as a relay of the information to the
cortex
The Interoceptive Sense is the Sense of
Internal Organ Function.
Praxis is the
ability to conceive of, plan, and organize a sequence of goal-directed motor actions.
Sensory Modulation is the ability to
respond adaptively to sensation over a broad range of intensity and duration.
Sensory Discrimination is the ability to interpret and differentiate between the
spatial and temporal qualities of sensory information—or the ‘‘where is it,’’ ‘‘what is it,’’ and ‘‘when did it occur’’ response.
Somatosensory Processing Deficits- poor discrimination of
tactile and proprioceptive information.
