• Understand the types of info transmitted and how the nervous system is divided based on these
• Understand the anatomical organisation of the somatic efferent division of the nervous system
• Understand how neurons communicate with effector cells
• Understand the anatomical oraganisation of the autonomic nervous system
• Understand how autonomic neurons communicate with effector cells
• Understand the differences between the sympathetic and parasympathetic
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].
Answer
voluntary
we are aware of
involuntary and unconscious
we are unaware of
Question 2
Question
Choose the incorrect statement about the somatic motor efferent division.
Answer
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.
Question 3
Question
One neuron can never innervate more than one muscle cell.
Answer
True
False
Question 4
Question
Choose the correct statements about the autonomic efferent motor division.
Answer
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
Question 5
Question
Choose the false statement about the autonomic nervous system.
Answer
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.
Question 6
Question
Norepinephrine is a more concentrated neurotransmitter than noradrenaline.
Answer
True
False
Question 7
Question
The autonomic nervous system has one afferent pathway, and two efferent pathways.
Answer
True
False
Question 8
Question
Choose the correct statement.
Answer
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.
Question 9
Question
The sympathetic chain ganglia has 21-23 pairs.
Answer
True
False
Question 10
Question
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].
