Neuro Lab 4 Flashcards
(28 cards)
Mammillary Body
Connected to Hippocampus via Fornix
Optic Chiasm
Crossing of Peripheral Visual Information from Both Eyes
Optic Tracts
Carries opposite visual field info from both eyes
Lateral Geniculate
Associated with Vision, Superior Colliculus and Brachium
Olfactory Tract and Bulb
Associated with sense of smell
Medial and Lateral Olfactory Striae
“Pathways” of Olfactory Tract
Cerebral Peduncles (Crus Cerebri)
Major White Matter Pathway from Brain Stem to Hemispheres
Interpeduncular Fossa
Space Between Cerebral Peduncles
Middle Cerebellar Peduncle
Communicates information from cerebrum to cerebellum
Pyramids/Pyramidal Decussation
Ventral Motor Pathway/ Crossing of Pathway
Olives
Superior-Laterally in Ventral Medulla/Climbing Fibers
Retro-Olivary Sulcus
Exit of CN 9, 10, and portions of 11
Lateral Geniculate
Associated with Vision and Superior Colliculus
Medial Geniculate
Associated with Audition and Inferior Colliculus
Tectum: Superior and Inferior Colliculus
Forms “Roof” over Cerebral Aqueduct
Brachium of Superior/Inferior Colliculi
Pathway connecting colliculi to geniculate bodies
Roof of 4th Ventricle
Superior and Inferior Medullary Velum
Facial Colliculus
Formed by CN VII arching dorsally around Abducens Nucleus, located towards the midline portion of the floor
Stria Medullaris
AKA “Acoustic Stria”, exit at Lateral Apetures
Sulcus Limitans
Groove where floor of 4th ventricle meets walls of ventricle. Division of Motor and Sensory Structures.
Obex/Area Postrema
Posterior/Lateral Walls of Obex, Area Postrema Associated with Vomiting
Dorsal Column Nuclei
NUCLEI Associated with Sensory Information from Body
Tuberculum Gracilis (Gracile Tubercle)
Lower Extremity Vibration, Joint Position, 2 point discrimination
Tuberculum Cuneatus (Cuneate Tubercle)
Upper Extremity Vibration, Joint Position, 2 point discrimination
