Questão 1
Questão
Control 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.
Responda
-
skeletal
-
voluntary
-
automatic
-
common
-
inhibitory
Questão 2
Questão
Choose the correct statements about reflexes
Responda
-
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.
Questão 3
Questão
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.
Responda
- True
- False
Questão 4
Questão
The sensory information delivered during a withdrawal reflex reaches the brain at the same time as the response is concluding.
Responda
- True
- False
Questão 5
Questão
Choose the incorrect statement about the corticospinal(pyramidal) tract.
Responda
-
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
Questão 6
Questão
Choose the incorrect statement.
Responda
-
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.
Questão 7
Questão
Choose the incorrect statement about the basal ganglia.
Responda
-
They act as a reward centre.
-
They are involved in addictive behaviours.
-
They release the hormone/neurotransmitter dopamine.
-
They only perform excitatory functions.
Questão 8
Questão
In 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].
Responda
-
dopamine
-
acetylcholine
-
inhibit
-
excite
-
initiated
-
terminated
