  1. 1Control of [blank_start]skeletal[blank_end] muscle can be a reflex movement, a precise [blank_start]voluntary[blank_end] movement, or an [blank_start]automatic[blank_end] movement. These all occur via a final [blank_start]common[blank_end] pathway, through a motor neuron. A motor neuron can never cause an [blank_start]inhibitory[blank_end] action.
    1. Askeletal
    2. Bvoluntary
    3. Cautomatic
    4. Dcommon
    5. Einhibitory
  2. 2Choose the correct statements about reflexes
    1. AA reflex movement is typically organised within the spinal cord.
    2. BReflex movement pathways have an interneuron in the brain.
    3. CA reflex movement is a predictable, reproducible automatic response to a particular stimulus.
    4. DStretch reflexes and withdrawal reflexes are common examples of reflexes.
  3. 3The major difference in the relay of neurons between the stretch and withdrawal reflex is that in the withdrawal reflex, a neuron in the CNS travels from the spinal cord interneuron to the brain to provide conscious sensory information.
    1. AVerdadeiro
    2. BFalso
  4. 4The sensory information delivered during a withdrawal reflex reaches the brain at the same time as the response is concluding.
    1. AVerdadeiro
    2. BFalso
  5. 5Choose the incorrect statement about the corticospinal(pyramidal) tract.
    1. AIt carries efferent information.
    2. BIt crosses over in the medulla.
    3. CThere is always an interneuron.
    4. DIt controls precise movement, e.g. in the hands and feet
  6. 6Choose the incorrect statement.
    1. AThe basal ganglia permit action potentials to be propagated from the motor cortex.
    2. BThe cerebellum can modify the motor program by comparing sensory feedback to expected feedback.
    3. CThe cerebellum maintains posture.
    4. DThe procedural memory is a development of memory of motor programs/automatic movements.
    5. EThe basal ganglia assure the movement is coordinated guided by sensory feedback.
  7. 7Choose the incorrect statement about the basal ganglia.
    1. AThey act as a reward centre.
    2. BThey are involved in addictive behaviours.
    3. CThey release the hormone/neurotransmitter dopamine.
    4. DThey only perform excitatory functions.
  8. 8In Parkinson's Disease, the basal nuclei do not receive [blank_start]dopamine[blank_end] and so they cannot [blank_start]inhibit[blank_end] the inhibitory functions which allow a movement to be [blank_start]initiated[blank_end].
    1. Adopamine
    2. Bacetylcholine
    3. Cinhibit
    4. Dexcite
    5. Einitiated
    6. Fterminated
