Proprioception Flashcards
Un-concious proprioception pathway projects into the _____________.
Un-concious proprioception pathway projects into the cerebellum.
_________ receptors detect changes in muscle length
Muscle Spindle receptors detect changes in muscle length
Clinical signs of proprioceptive defects
Ataxia
Knucking over, dragging toes
Failure of CP tests
Describe the Trigeminal Pathway
Trigeminal nucleus to principal nucleus
Principal nucleus (Deccussation) to medial lemniscus
Medial lemniscus to VCM
VCM to cortex
Two pathways of concious proprioception
Dorsal Column-Medial Lemniscus (DCML) Pathway
Trigeminal Pathway
Concious proprioception tests
Proprioceptive positioning
Wheelbarrowing
Hopping
Hemistanding/hemiwalking
Placing
Concious proprioception pathway terminates in the ___________ of the cerebrum.
Concious proprioception pathway terminates in the Somatesthetic cortex of the cerebrum.
Vulnerablity of proprioception pathways to damage is due to
Large Axons
Superficial location on the spinal cord
Describe the DCML Pathway
Dorsal Root to fasiculus cuneatus/gracilis
Fasiculus cuneatus/gracilis to nucleus cuneatus/gracilis
Nucleus cuneatus/gracilis (deccussation) to medial lemniscus
Medial lemniscus to VCL
VCL to Cortex
____________ receptors detect tension in tendons

________ receptors detect pressure and stretch in join capsule
Joint receptors detect pressure and stretch in join capsule
Skin mechanoreceptors are important in the __________ pathway
Skin mechanoreceptors are important in the DCML pathway
_________ ataxia due to a lesion in the vestibular apparatus, vestibular clinical signs can be seen.
Vestibular ataxia due to a lesion in the vestibular apparatus, vestibular clinical signs can be seen.
Three kinds of ataxia
Proprioceptive Ataxia
Vestibular Ataxia
Cerebellar Ataxia
_____________ is essential for well timed and accurate movements.
Proprioception is essential for well timed and accurate movements.
T/F: Proprioception deficits are first effected in injury to spinal cord.
True
_________ ataxia due to a lesion in proprioceptive pathway, abnormal posture with paresis clinical signs
Proprioceptive ataxia due to a lesion in proprioceptive pathway, abnormal posture with paresis clinical signs
___________ ataxia due to a lesion in the cerebellum, cerebellar clinical signs present.
Cerebellar ataxia due to a lesion in the cerebellum, cerebellar clinical signs present.
Describe the progression of deficits that occurs with spinal cord damage
