Exam 10: Controlling Posture and Locomotion

The largest cell bodies in the cerebellum are the ______________cells although the most numerous are the ______________.

Refer to Figure 10.11, In the text if the wire was attached to the right hand and the cup held in the left hand during this postural reflex experiment, what would you expect to be true?

The only neurotransmitter used for signaling by the Purkinje neurons is ________.

Refer to the diagram below and correctly identify if the synapses labeled a and b are excitatory or inhibitory.

All of the following are part of the motor cortex in primates, except

Match each reflex with it's appropriate function: -_____rapid bending at the knee when your foot experiences a sharp stimulus

Which of the following reflexes are independent of visual signals?

Experiments with monkeys tracking hand movements with electrical stimulation to different sites in the motor cortex revealed what information about the motor cortex map?

Match each scientist with their appropriate contribution to understanding of the control of posture and locomotion -_____ conducted seminal experiments in lampreys to demonstrate that the core of the CPG for lampreys is a half-center oscillator

Match each division of the cerebellum with it's appropriate function: -_____sends and receives synaptic input from the frontal lobe

The motor cortex and spinal cord both contribute to the control of voluntary movements. Give an example from the text that provides evidence for the idea that control of walking is highly coordinated by the spinal cord.

After amputation of a limb, what might you might expect that in the area of the motor cortex that originally sent information to that missing limb

How might you determine if walking involves a central pattern generator or a chain of sensorimotor reflexes in an IACCUC-approved species not already discussed in the chapter?

Explain why miners that spend large amounts of time in very dim places might have pupils that are especially sensitive to light.

According to Penfield's motor homunculus, which body parts receive the most neural input from the motor cortex.
