Resumo de Recurso

Questão 1

Questão
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].
Responda
  • voluntary
  • we are aware of
  • involuntary and unconscious
  • we are unaware of

Questão 2

Questão
Choose the incorrect statement about the somatic motor efferent division.
Responda
  • 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.

Questão 3

Questão
One neuron can never innervate more than one muscle cell.
Responda
  • True
  • False

Questão 4

Questão
Choose the correct statements about the autonomic efferent motor division.
Responda
  • 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

Questão 5

Questão
Choose the false statement about the autonomic nervous system.
Responda
  • 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.

Questão 6

Questão
Norepinephrine is a more concentrated neurotransmitter than noradrenaline.
Responda
  • True
  • False

Questão 7

Questão
The autonomic nervous system has one afferent pathway, and two efferent pathways.
Responda
  • True
  • False

Questão 8

Questão
Choose the correct statement.
Responda
  • 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.

Questão 9

Questão
The sympathetic chain ganglia has 21-23 pairs.
Responda
  • True
  • False

Questão 10

Questão
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].
Responda
  • 3
  • 2
  • preganglionic
  • postganglionic
  • chain ganglia
  • their effectors
