Ascending Pathways Flashcards
Dorsolateral Fasiculus also known as
Tract of Lissauer
Function of Dorsolateral Fasiculus
Accepting projecting axons carrying discriminating pain, temperature and information
Substancia Gelatinosa known as
Lamina 2
Function of Anterior funiculus
Motor information
Function of posterior funiculus
Sensory information
Function of Lateral funiculus
Autonomic function
What is responsible for Conscious proprioception
Fasiculus cuneatus and gracilis
Lateral spinothalamic tract function
Pain and temperature
Spinotectal Tract function
Spino-visual information (eyes and head towards source of stimulation)
Spinoreticular tract function
Consciousness
Spino-olivary tract function
Proprioceptive organs
Lateral spinothalamic tract pain characteristic
Type A delta and Type C
Where does the lateral spinothalamic tract crosses?
Midline at the anterior white and grey commissure
Post central gyrus
Relation to past experience
Cingulate gyrus of the limbic system
Emotional aspect of pain
Insular gyrus
Pain from internal organs
anterior spinothalamic tract
Touch and pressure
Fasiculus gracilis starts and ends where
T6 to Sacral portion
Fasiculus cuneatus starts and ends where
Cervical to T6
What are the receptors for proprioception
Muscle spindles and GTO
Where does the posterior column crosses over?
Level of the medulla
Spinocerebellar function
Transmits unconscious proprioception to the cerebellum
N1 for Pain and Temperature Pathway
Trigeminal ganglion 5
Geniculate ganglion 7
Petrossal ganglion 9
Superior ganglion 10
Major sensory for the face
Cranial nerve 5
Back of the ears
Cranial nerve 7
Nerve for the skin of the ears
Cranial nerve 9 or 10
N2 for discriminative touch and pressure
Main sensory nucleus of cn 5
N1 for conscious proprioception (dorsal and ventral trigeminothalamic)
Mesencephalic nucleus
N2 for conscious proprioception (dorsal and ventral trigeminothalamic)
Main motor nucleus of CN 5
Nucleus dorsalis is also known as
Clarke’s column
