  2. Cerebral peduncle - Wikipedia

    en.wikipedia.org/wiki/Cerebral_peduncle

    The region includes the tegmentum, crus cerebri and pretectum. By this definition, the cerebral peduncles are also known as the basis pedunculi, while the large ventral bundle of efferent fibers is referred to as the cerebral crus (crus means ‘leg’ in Latin.) or the pes pedunculi (pes means 'foot' in Latin.).

  3. Cerebral crus - Wikipedia

    en.wikipedia.org/wiki/Cerebral_crus

    The cerebral crus (crus cerebri. crus means ‘leg’ in Latin.) is the anterior portion of the cerebral peduncle which contains the motor tracts, traveling from the cerebral cortex to the pons and spine. The plural of which is cerebral crura. In some older texts, this is called the cerebral peduncle, but presently, it is usually limited to ...

  4. Midbrain - Wikipedia

    en.wikipedia.org/wiki/Midbrain

    The cerebral peduncles each form a lobe ventrally of the tegmentum, on either side of the midline. Beyond the midbrain, between the lobes, is the interpeduncular fossa, which is a cistern filled with cerebrospinal fluid [citation needed]. The majority of each lobe constitutes the cerebral crus.

    Cerebral peduncle. Crus cerebri; Mesencephalic cranial nerve nuclei. Oculomotor nucleus (III) Edinger-Westphal nucleus; Trochlear nucleus (IV) Mesencephalic duct (cerebral aqueduct, aqueduct of Sylvius)

  6. Tegmentum - Wikipedia

    en.wikipedia.org/wiki/Tegmentum

    The midbrain tegmentum is the part of the midbrain extending from the substantia nigra to the cerebral aqueduct in a horizontal section of the midbrain. Structures included in the midbrain tegmentum include the red nucleus, reticular formation, and substantia nigra. The red nucleus is responsible for controlling basic body and limb movements.

  7. Internal capsule - Wikipedia

    en.wikipedia.org/wiki/Internal_capsule

    The internal capsule is a paired white matter structure, as a two-way tract, carrying ascending and descending fibers, to and from the cerebral cortex. The internal capsule is situated in the inferomedial part of each cerebral hemisphere of the brain. It carries information past the subcortical basal ganglia.

  8. Interpeduncular cistern - Wikipedia

    en.wikipedia.org/wiki/Interpeduncular_cistern

    The interpeduncular cistern (or basal cistern [1]) is the subarachnoid cistern situated between the dorsum sellae (anteriorly) [2] and the two cerebral peduncles [1] [3] [2] at the front of the midbrain. [3] Its roof is represented by the floor of the third ventricle (i.e. posterior perforated substance, and the two mammillary bodies).

  9. Brainstem - Wikipedia

    en.wikipedia.org/wiki/Brainstem

    The tectum comprises the paired structure of the superior and inferior colliculi and is the dorsal covering of the cerebral aqueduct. The inferior colliculus is the principal midbrain nucleus of the auditory pathway and receives input from several peripheral brainstem nuclei, as well as inputs from the auditory cortex.
