Study These Flashcards

A

Cerebral (mesencephalic) aqueduct

Q

What are the CSF exit points from the fourth ventricle?

Study These Flashcards

A

Two lateral apertures and one median aperture

Q

What are the three meningeal layers?

Study These Flashcards

A

Dura mater, arachnoid mater, pia mater

Q

What is the falx cerebri?

Study These Flashcards

A

A dural fold separating the cerebral hemispheres

Q

What is the tentorium cerebelli?

Study These Flashcards

A

A dural fold separating the cerebellum from occipital/temporal lobes

Q

What is the function of arachnoid granulations?

Study These Flashcards

A

Reabsorb CSF into the superior sagittal sinus

Q

Where is the thalamus located and what is its function?

Study These Flashcards

A

Inferior to the body of the lateral ventricles and bilateral to the 3rd ventricle
Major relay to/from cortex

Q

Where is the hypothalamus located and what is its function?

Study These Flashcards

A

Dorsal of the thalamus
Regulates homeostasis

Q

What are the mammillary bodies?

Study These Flashcards

A

Round structures on the underside of the hypothalamus

What is the location and function of the superior colliculi?

* Dorsal midbrain * Visual and auditory orienting reflexes

What is the location and function of the inferior colliculi?

* Dorsal midbrain * Auditory spatial mapping and prioritization

What is the function of the superior brachium?

Connects the superior colliculus and lateral geniculate nucleus (thalamus)

What is the function of the superior brachium?

Connects the inferior colliculus and medial geniculate nucleus (thalamus)

What are the cerebral peduncles?

White matter tracts connecting brainstem and cortex

What is the basilar sulcus?

A midline groove on the anterior pons for the basilar artery

What are the three cerebellar peduncles and their functions?

* Superior: efferent to cortex and red nucleus * Middle: afferent from pons * Inferior: afferent from medulla and spinal cord

What are the medullary pyramids?

Ridges on the anterior medulla containing corticospinal tract fibres

What are the medullary olives?

Oval structures lateral to the pyramids; contain inferior olivary nucleus

What are the gracile and cuneate tubercles?

Landmarks on the dorsal medulla of the gracile and cuneate nuclei (fine touch/proprioception)

What is the anterior median fissure?

Groove on the anterior surface of the spinal cord and medulla
