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.
Cerebellum: Cerebellum is the second largest part of brain (after cerebrum). It lies within the posterior cranial fossa beneath the tentorium cerebelli. Its position in the hindbrain is posterior to both pons and medulla oblongata.It is connected to the midbrain through superior cerebellar peduncles, to the pons through middle cerebellar peduncles and to the medulla through inferior cerebellar peduncles.ons is situated below the midbrain and above the medulla oblongata anterior to the cerebellum. It is mainly composed of those nerve fibers that connect the two halves of cerebellum. In addition, it also contains the ascending and descending fibers connecting the forebrain, midbrain and the spinal cord.
