Sharpening pencils is not only time-consuming, it can also be frustrating trying to achieve that perfectly pointed tip. Eliminate the hassle of sharpening with mechanical pencils that use lead refills that advance and retract with either twist-action or click-action to keep a sharp point constantly at the ready.
Overview. Problems. Contents. Anatomy. Point: 18. Superior cerebellar peduncle. Function: Principle efferent (out of) pathway of the cerebellum. Plays a major role in the coordination of the IPSI. arm and leg.esion of the superior cerebellar peduncle CAUDAL to the decussation will result in motor incoordination on the IPSI. side of the body, whereas a lesion that occurs ROSTRAL to the decussation results in CONTRA. motor incoordination of the arm and leg. Other Note: REMEMBER THAT CEREBELLAR LESIONS RESULT IN IPSI.
The corpora quadrigemina (quadruplet bodies) are four solid lobes on the dorsal side of the cerebral aqueduct, where the superior posterior pair are called the superior colliculi and the inferior posterior pair are called the inferior colliculi.The four solid lobes help to decussate several fibres of the optic nerve.he midbrain comprises the tectum (or corpora quadrigemina), tegmentum, the cerebral aqueduct (or ventricular mesocoelia or iter), and the cerebral peduncles, as well as several nuclei and fasciculi.
