Neuroscience - Unit 11 USAHS questions with complete solutions 2023/2024

Neuroscience - Unit 11 USAHSFunctions of the cerebellum - correct answer Receives sensory information from both the brain and the spinal cord about body position and movement (rate, timing, and force) It tells the brain if it's doing too much or too little It compares what the actual movement is to what the brain intended and adjusts as needed Keeps movement going without us needing to think about it Exerts its influence by sending information back to motor systems of the cortex and the brainstem to correct movement Cerebellum function: Synergy of Movement - correct answer Properly grouping movements for the performance of selective responses and also has a major role in learning Muscle synergies: proper movement groups EX: picking up your phone Stroke patients have abnormal synergies Cerebellum function: Posture - correct answer Maintenance of Upright with respect to one's position in space Cerebellum function: Maintenance of Tone - correct answer Maintaining tension/firmness (i.e. tone) during a muscle contraction 3 functional regions of cerebellum - correct answer 1 & 2. Lateral region & Intermediate Zone: Control our limbs 3. Vermis and flocculus/flocculonodular lobes (Medial): Controls our trunk Region of cerebellum: lateral hemispheres Function & Motor Pathway Influenced - correct answer Motor planning for extremities
