Levator Scap
What does the Fasciculus Cuneatus do?
It is an ascending tract that collects sensory information from trunk neck and UE (proprioception, vibration, 2-pt discrimination, and graphesthesisa)
What does the Fasciculus gracilis do?
It is an ascending tract that collects sensory information from from trunk and LE (proprioception, vibration, 2-pt discrimination, and graphesthesisa)
What does the Spinocerebellar tract do? (dorsal and Ventral)
This is a sensory tract that ascends to the cerebellum for subconscious proprioception, muscle tension, joint sense and posture (dorsal= LE ; ventral =UE)
What does the Anterior spinothalamic tract do?
sensory tract for light touch and pressure
What does the Lateral spinothalamic tract do?
sensory tract for pain and temperature
What does the Anterior Corticospinal tract do?
it is a pyramidal motor tract responsible for ipsilateral voluntary discrete skilled movements
What does the Lateral Corticospinal tract do?
it is a pyramidal motor tract responsible for contralateral voluntary fine movements.
What happens if the pyramidal tracts are injured?
positive babinski sign, absent superficial abdominal reflex and cremasteric reflex, loss of fine motor and or skilled movements
What does the Tectospinal tract do?
it is an extrapyramidal tract that is responsible foe for contralateral postural muscle tone associated with auditory and visual stimuli
