CONFUSING PARTS NERVOUS SYSTEM Flashcards
Inferior cuniculli
Auditory pathway in brain stem
Superior cuniculli
Sensory info on visual space, auditory space, somatosensory space
Posterior horns
Sensory processing spinal cord (gray matter)
Anterior horns
Motor response to skeletal (gray matter)
Lateral horns
Region found in upper lumbar, sacral, responsible for ANS
Ascending tracts
Sends sensory info to brain (white matter)
Descending tracts
Send motor output from brain (white matter)
Dura mater
Thick strong protective sheath over entire brain and spinal cord
Arachnoid mater
Forms thin loose sacs around CNS and has arachnoid trabecular found beneath (filament mesh layer)
Pia mater
Thin membrane following convolutions/indentation of gyri and sulcus on cerebral cortex
Lateral ventricle
Deep in cerebrum
3rd ventricle
Between left and right of diencaphalon
4th ventricle
Between cerebellum and pons/medulla
Pathway of CSF
lateral ventricle –> 3rd ventricle –> cerebral adequcdt –> 4th ventricle –> subarachnoid space –> canal of spinal cord
Dorsal root ganglion
Emerges from dorsal root of spinal nerves carrying sensory messages from various receptors at periphery to CNS
