Pregunta 1
Pregunta
The somatic nervous system controls efferent, [blank_start]voluntary[blank_end] motor control, and afferent sensory information [blank_start]we are aware of[blank_end].
Autonomic efferent muscle control is [blank_start]involuntary and unconscious[blank_end], and afferent sensory information [blank_start]we are unaware of[blank_end].
Respuesta
-
voluntary
-
we are aware of
-
involuntary and unconscious
-
we are unaware of
Pregunta 2
Pregunta
Choose the incorrect statement about the somatic motor efferent division.
Respuesta
-
It effects only skeletal muscle.
-
There is only one axon between the CNS and effector, and it is unmyelinated.
-
The neuronal cell body is within the spinal cord.
Pregunta 3
Pregunta
One neuron can never innervate more than one muscle cell.
Respuesta
- True
- False
Pregunta 4
Pregunta
Choose the correct statements about the autonomic efferent motor division.
Respuesta
-
There are 2 neurons between the CNS and the effector.
-
Both neurons have their cell bodies in the CNS.
-
Both neurons have their axons in the PNS.
-
Effectors include smooth muscle, cardiac muscle, glands, and adipose tissue
Pregunta 5
Pregunta
Choose the false statement about the autonomic nervous system.
Respuesta
-
The preganglionic autonomic motor neuron is myelinated.
-
The postganglionic neuron is unmyelinated.
-
The neurotransmitter released at the synapse of the preganglionic neuron to the postganglionic neuron can be ACh or norepinephrine.
-
The neurotransmitter released at the synapse of the postganglionic neuron to the effector can be ACh or norepinephrine.
Pregunta 6
Pregunta
Norepinephrine is a more concentrated neurotransmitter than noradrenaline.
Respuesta
- True
- False
Pregunta 7
Pregunta
The autonomic nervous system has one afferent pathway, and two efferent pathways.
Respuesta
- True
- False
Pregunta 8
Pregunta
Choose the correct statement.
Respuesta
-
The parasympathetic nervous system can also be called the thoracolumbar nervous system.
-
The sympathetic nervous system can also be called the craniosacral nervous system.
-
The preganglionic neuron of the sympathetic division is short, while the postganglionic neuron is long.
-
The postganglionic neuron of the parasympathetic nervous system is long and synapses in the chain ganglia.
Pregunta 9
Pregunta
The sympathetic chain ganglia has 21-23 pairs.
Respuesta
- True
- False
Pregunta 10
Pregunta
There are [blank_start]3[blank_end] main collateral ganglia, which contain [blank_start]preganglionic[blank_end] axons that did not make synapses in [blank_start]chainganglia[blank_end].
Respuesta
-
3
-
2
-
preganglionic
-
postganglionic
-
chain ganglia
-
their effectors
