L29 Somatic Control: Voluntary and Reflex

Frage 1 von 8

1

Control of muscle can be a reflex movement, a precise movement, or an movement. These all occur via a final pathway, through a motor neuron. A motor neuron can never cause an action.

    skeletal
    voluntary
    automatic
    common
    inhibitory

Erklärung

Frage 2 von 8

1

Choose the correct statements about reflexes

Wähle eine oder mehr der folgenden:

  • A reflex movement is typically organised within the spinal cord.

  • Reflex movement pathways have an interneuron in the brain.

  • A reflex movement is a predictable, reproducible automatic response to a particular stimulus.

  • Stretch reflexes and withdrawal reflexes are common examples of reflexes.

Erklärung

Frage 3 von 8

1

The 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.

Wähle eins der folgenden:

  • WAHR
  • FALSCH

Erklärung

Frage 4 von 8

1

The sensory information delivered during a withdrawal reflex reaches the brain at the same time as the response is concluding.

Wähle eins der folgenden:

  • WAHR
  • FALSCH

Erklärung

Frage 5 von 8

1

Choose the incorrect statement about the corticospinal(pyramidal) tract.

Wähle eine der folgenden:

  • It carries efferent information.

  • It crosses over in the medulla.

  • There is always an interneuron.

  • It controls precise movement, e.g. in the hands and feet

Erklärung

Frage 6 von 8

1

Choose the incorrect statement.

Wähle eine oder mehr der folgenden:

  • The basal ganglia permit action potentials to be propagated from the motor cortex.

  • The cerebellum can modify the motor program by comparing sensory feedback to expected feedback.

  • The cerebellum maintains posture.

  • The procedural memory is a development of memory of motor programs/automatic movements.

  • The basal ganglia assure the movement is coordinated guided by sensory feedback.

Erklärung

Frage 7 von 8

1

Choose the incorrect statement about the basal ganglia.

Wähle eine der folgenden:

  • They act as a reward centre.

  • They are involved in addictive behaviours.

  • They release the hormone/neurotransmitter dopamine.

  • They only perform excitatory functions.

Erklärung

Frage 8 von 8

1

In Parkinson's Disease, the basal nuclei do not receive and so they cannot the inhibitory functions which allow a movement to be .
