Chapter Fourteen Brain Control of Movement
1. In the hierarchy of motor control, which of the following is a function at the lowest level
of control? Choose the correct option.
A) Activation of motor neurons that generate goal-directed movement
B) Sequences of muscle contraction to accurately achieve the goal
C) The goal of movement and the best method to achieve this goal
D) Memory of sensory information from the past movements
2. What is the function of lateral pathways with regard to the descending motor pathways?
Choose the correct option.
A) Control the posture and locomotion
B) Control the voluntary movement of distal musculature
C) Control the sensory modification of motor control
D) Control balance of head and shoulders
3. Which cortical area is referred to as the primary motor cortex? Choose the correct
option.
A) Area 8
B) Area 5
C) Area 6
D) Area4
4. Which of the following is true about how Ml commands voluntary movement? Choose
the correct option.
A) The motor cortex is active only for complex voluntary movements.
B) The activity of each cell cast multiple votes for a particular direction of movement.
C) The direction of movement is determined by spinal reflex mechanisms.
D) The activity of each cell represents a single vote for a particular direction of
movement and the direction of movement is determined by averaging the votes in
the population.
5. Which of the following is a symptom of cerebellar damage? Choose the correct option.
A) Tremors of the hands and jaws
B) Abnormal movements, dementia, and kinesia
C) Sequential joint movement and dysmetria
D) Difficulty in initiating willed movements
