Q

Inferior Colliculi

A

The two inferior bilateral protrusions on the posterior side of the pons immediately inferior to the superior colliculi of the corpora quadrigemina

17
Q

Pons

A

The aspect of the brainstem inferior to the midbrain and superior to the medulla. The anterior side swells out and the posterior side articulates with the cerebellum

18
Q

medulla oblongata

A

The aspect of the brainstem immediately inferior to the pons and superior to the spinal cord.

19
Q

Pyramids of the Medulla Oblongata

A

Slight bilateral protrusions on the anterior side of the medulla oblongata

20
Q

Corpus Callosum

A

Brain tissue located within the longitudinal fissure of the brain. In a transected brain, it is found immediately inferior to the parietal lobe of the cerebrum.

21
Q

Lateral Ventricles

A

Bilateral openings in the brain filled with CSF. In a transected brain, they are located immediately inferior to the corpus callosum and superior to the thalamus.

22
Q

3rd ventricle

A

Open Space filled with CSF that sits on the midline of the brain. On a transected brain it sits immediately inferior to the corpus callosum and superior/anterior to the pituitary gland/thalamus

23
Q

4th ventricle

A

An Open space filled with CSF located between the pons and the cerebellum.

24
Q

Thalamus

A

Portion of the brain immediately superior to the midbrain and inferior to the third ventricle and the corpus callosum. It is also superior to the hypothalamus.

25
Q

hypothalamus

A

portion of the brain that sits on the midline. It is anterior and inferior to the thalamus. It is also posterior to the inferior portion of the frontal lobe.

26
Q

Pineal body

A

protrusion on the posterior side of the thalamus. It sits on the midline and is immediately superior to the superior colliculi of the corpora quadrigemina.

27
Q

Meninges

A

Located on the exterior surface of the brain

28
Q

Dura Mater

A

Outter layer of the meninges. Directly inferior to the bone of the skull and superior to the arachnoid mater Tough outer layer.

29
Q

Arachnoid Mater

A

Located inferior to the dura mater and superior to the pia mater. Layer has web-like structure.

30
Q

Pia Mater

A

located on the exterior of the cerebrum, inferior to the arachnoid and pia mater.
