Topographic Anatomy Flashcards
Conus Medullaris
Lowest tapering portion of the spinal cord
Filum terminale interna
Continuation of the pia mater from the end of the conus
Cauda equina
Lumbar and sacral nerve roots arising from the conus
Where does the anterior median sulcus run?
In the anterior spinal artery
Where is the dorsal intermediate sulcus located?
Between the dorsal median sulcus and the dorsolateral sulcus.
It is only present in the upper part of the spinal cord
Location of Dorsal Funiculus?
Between posterior median and posterolateral sulci
Location of Lateral funiculus?
Between dorsolateral sulcus and the ventrolateral sulcus
Location of ventral funiculus?
Between ventrolateral sulcus and anterior median sulcus
What happens when you have damage to dorsal part of the spinal cord?
It will cause loss of ability to detect vibration, discriminate touch and recognize movements of the affected limbs.
What is the substantia gelatinosa?
The most posterior portion of the dorsal horn. It is a processing center for pain
What is major function of the cerebellum? What happens when you have damage to the basal pons, middle peduncle or cerebellum
Coordinating skilled movements of the ipsilateral side of the body.
Damage causes incoordination
Abducens Nerve
Cranial nerve VI: Lateral eye movement
Facial Nerve
Cranial nerve VII: movement of muscles of facial expression
Hypoglossal Nerve
CN XII: Motor to the tongue
Glossopharyngeal nerve
CNIX: Control pharynx
