1. lateral spinothalamic tract

what is the pathway in the lateral funiculus?

dorsal and ventral spinocerebellar tract

deals with muscle stretch and aids with balance and posture

muscle stretch

what does the ventral spinocerebellar do?

balance and posture

what does the dorsal spinocerebellar do?

what does the fasiculus cuneatus connect the spinal cord to?

1. two point (fine) touch

2. vibration sense

3. proprioception

what functions does the fasiculus cuneatus and gracilis do?

proprioception

sense of your body in space

Romberg test

used to evaluate cerebellar function and balance

medulla oblongata

where do the fasciculus gracilis and fasciculus cuneatus cross at?

pain and temperature

What does the lateral spinothalamic tract carry?

light (crude) touch

what does the ventral spinothalamic tract carry?

1. corticospinal tract

2. corticobulbar tract

what are the pyramidal pathways?

tectospinal tract

important for auditory and visual reflexes

pyramids of brain

where do the pyramidal pathways cross?

corticospinal tract

moves all your skeletal muscles

contralateral

what kind of pathway is the corticospinal?

corticobulbar tract

innervates skeletal muscles, inhibits reflexes for speech and swallowing

corticospinal tract

innervates skeletal muscles, activates muscles and inhibits reflexes
