Preguntas del test (8)
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.
- Askeletal
- Bvoluntary
- Cautomatic
- Dcommon
- Einhibitory
2Choose the correct statements about reflexes
- AA reflex movement is typically organised within the spinal cord.
- BReflex movement pathways have an interneuron in the brain.
- CA reflex movement is a predictable, reproducible automatic response to a particular stimulus.
- DStretch reflexes and withdrawal reflexes are common examples of reflexes.
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.
- AVerdadero
- BFalso
4The sensory information delivered during a withdrawal reflex reaches the brain at the same time as the response is concluding.
- AVerdadero
- BFalso
5Choose the incorrect statement about the corticospinal(pyramidal) tract.
- AIt carries efferent information.
- BIt crosses over in the medulla.
- CThere is always an interneuron.
- DIt controls precise movement, e.g. in the hands and feet
6Choose the incorrect statement.
- AThe basal ganglia permit action potentials to be propagated from the motor cortex.
- BThe cerebellum can modify the motor program by comparing sensory feedback to expected feedback.
- CThe cerebellum maintains posture.
- DThe procedural memory is a development of memory of motor programs/automatic movements.
- EThe basal ganglia assure the movement is coordinated guided by sensory feedback.
7Choose the incorrect statement about the basal ganglia.
- AThey act as a reward centre.
- BThey are involved in addictive behaviours.
- CThey release the hormone/neurotransmitter dopamine.
- DThey only perform excitatory functions.
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].
