Is the brainstem supratentorial?
The supratentorial area contains the cerebrum, lateral ventricle, third ventricle, choroid plexus, hypothalamus, pineal gland, pituitary gland, and optic nerve. The posterior fossa/infratentorial area contains the cerebellum, tectum, fourth ventricle, and brain stem (pons and medulla).
What is infratentorial?
Medical Definition of infratentorial : occurring or made below the tentorium cerebelli an infratentorial tumor.
Is the midbrain supratentorial?
The supratentorial compartment includes the cerebral hemispheres and the sellar, pineal, and diencephalic regions, whereas the infratentorial compartment includes the midbrain, pons, medulla, and cerebellum.
What part of the brain is supratentorial?
cerebrum
The supratentorial area (the upper part of the brain) contains the cerebrum, lateral ventricle and third ventricle (with cerebrospinal fluid shown in blue), choroid plexus, pineal gland, hypothalamus, pituitary gland, and optic nerve.
What does the supratentorial brain control?
In his proposed scheme, while the supratentorial parts (mainly the cerebrum) were responsible for planning and control of movement in the world, the infratentorial parts (mainly the cerebellum) were responsible for planning and control of bodily motion per se.
Is the occipital lobe supratentorial?
The image below shows a side (lateral) view of the tentorium cerebelli – an extension of the dura matter that separates the cerebellum from the bottom (inferior) portion of the occipital lobes. Tumors below the tentorium are called infratentorial and those above are called supratentorial.
Is thalamus supratentorial?
Structures located above the tentorium are supratentorial. The major supratentorial structures are the cerebral hemispheres, basal ganglia, thalamus, hypothalamus, and cranial nerves I (olfactory) and II (optic).
What is Cerebellopontine?
The cerebellopontine angle is a space filled with spinal fluid. It has the brain stem as its medial boundary, the cerebellum as its roof and posterior boundary, and the posterior surface of the temporal bone as its lateral boundary.
What is supratentorial region of brain?
The supratentorial area (the upper part of the brain) contains the cerebrum, lateral ventricle and third ventricle (with cerebrospinal fluid shown in blue), choroid plexus, pineal gland, hypothalamus, pituitary gland, and optic nerve. The skull and meninges protect the brain and spinal cord (left panel).
Where is a supratentorial tumor located?
Brain tumors located in the lobes are called supratentorial and tumors located in the cerebellum or brainstem are called infratentorial.

What does supratentorial region mean?
Supratentorial region. In anatomy, the supratentorial region of the brain is the area located above the tentorium cerebelli. The area of the brain below the tentorium cerebelli is the infratentorial region.
What does supratentorial neoplasms mean?
Supratentorial Neoplasms Primary and metastatic (secondary) tumors of the brain located above the tentorium cerebelli, a fold of dura mater separating the CEREBELLUM and BRAIN STEM from the cerebral hemispheres and DIENCEPHALON (i.e., THALAMUS and HYPOTHALAMUS and related structures).
