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 superior colliculus refers to the rostral (front) bump on the lateral (side) part of the midbrain. It is, in fact, a pair of two colliculi, superior and inferior, on either side of the midbrain that together constitute the tectum.The superior colliculus is a layered, multi-sensory structure.Its upper layer receives visual signals from the retina of the eye, while the lower layers process multiple signals from various other parts of the brain. This colliculus is not restricted to a visual role alone.ovement of the eyes is also connected with the cells present in the lower layers of the colliculus. In mammals and other higher animals, the brain processes sensory inputs in correlation with the superior colliculus. In lower animals it helps to perceive any sudden movement that occurs before the retina.
