16 And 17 Flashcards
Spinothalamic anterior pathway
Cross in spinal cord. Crude touch and pressure
Posterior column pathway
Cross in medulla sensory impulses from skin muscles tendons and joints
Spinothalamic lateral pathway
Cross in spinal cord. Pain and temp
Spinocerebellar anterior
Cross in medulla proprioception for fine coordination
Posterior spinocerebellar
Doesn’t cross. Prop for fine coordination
Corticospinal
Controls voluntary movement
Corticobubular
Motor cranial nerves
Lateral corticospinal
Motor spinal nerves crosses in medulla
Anterior corticospinal
Doesn’t cross over. Motor spinal nerves
Medial pathway verstibulospinal
Position and hear movement
Medial tectospinal
Reflexive head movement
Medial reticulospinal
Movement and muscles of trunk and proximal limb
Lateral descending. Rubrospinal
Start in red Nucleus cross over extend to cerivical region skeletal muscles
Of upper distal limb
Sympathetic chain ganglia
3 cervical 12 thoracic 2-5 lumbar 4-5 sacral 1 coccygeal
Preganglionic fibers originate in what region
T1-l2
Postganglionic fibers that have been modified into glandular cells known as
Chromaffin cells
In sympathetic activation what receptor is on the target tissue
Adrenergic
Sympathetic preganglionic fibers are short or long
Short
Cranial nerve ten and s2-4
Parasympathetic converge in large autonomic plexus and tater heart lungs gi tract urinary tract and sexual organs
Dual innervation cranial area
Sympathetic reaches via chain ganglia parasympathetic reaches via cranial ganglia
Dual innervation thoracic and ab
Mingle at Cardiac plexus and esophageal
