Flashcards in Pathways Deck (29)
Which pathways are reactive?
Which pathways are discriminative?
Dorsal column-medial leminicsus
Which motor pathways are voluntary?
Pyramidal- cerebral cortex
Which motor pathways are involuntary/ autonomous?
What is spinothalamic
Spinal cord- thalamus- cortex
Anterior- Pressure and tough
Lateral- Pain and temp
What is dorsal column-medial leminiscus pathway?
Lemon with good posture (proprioceptive)
T6 above- cunate nucleus
T6 below- gracile nucleus
Light touch/ vibration
What is spinocerebellum
Spine to cerebellum
What is corticospinal?
Ends at spinal cord
-lateral pyramids of medulla
-anterior spinal cord
What is corticobulbar?
Head and neck
Ends at brainstem
What is reticulospinal?
Reticular formation to spinal cord
Facilitates and inhibits voluntary movement
What is tectospinal?
Tectum (Superior colliculi) to spinal cord
Vision- head moves towards the light
What is ruborospinal?
Red nucleus to spinal cord
Caught red handed
fine control of hand
What is vestibulospinal?
Vestibular nuclei to spinal cord
What do the inferior and superior colliculi do?
actually speaking-frontal (motor)
Pre central gyrus
Post central gyrus
Touch something, feel it later
What is the limbic system?
Inlcudes thalamus, hypothalamus, basal nuclei, cerebral cortex and olefactory cortex
Controls visceral functions through the autonomic NS and endocrine
Involved in- Emotions, memory, reproduction and nutrition
What are the 3 cerebral white matter fibres?
What are association fibres?
Same hemisphere, connect areas
What are projection fibres?
Connect one cerebrum to other part of the brain/spinal cord
Example= Internal capsule
What are commissure fibres?
Connect one hemisphere to the other
Example- corpus collosum
What is the occipital part of the brain for?
What is the frontal part of the brain for?
Personality and memory, emotion and motor
What is parietal for?
Language and touch- contains wernickes area
What is the cerebellum for?
Movement and coordination
What is the temporal for?
Hearing, learning and feelings
