Neurons

The functional unit that makes up the nervous system

• nodes

• neurons

• nephrons

• synapses

Which of the following is not a part of the neuron?

• axon

• dendrites

• cell body

• neurotransmitter

the direction the impulse travels in this neuron

• to the right -->

• to the left <--

Which is the correct function for the structures mentioned ( choose all that are correct)

• dendrite conducts impulses to the axon

• Axon carries nerve impulses from the cell body to muscles

• cell body carries nerve impulses to the dendrite

• the cell body contains the nucleus and cell organelles

The gaps in the myelin sheath are called---

• nodes

• synapses

• reflexes

• potentials

The three types of neurons shown in the diagram are

• 1= interneuron. 2= motor neuron 3= sensory neuron

• 1= sensory neuron. 2= motor neuron. 3= interneuron

• 1 = interneuron. 2 = sensory neuron. 3= motor neuron

• 1= motor neuron. 2 = sensory neuron. 3= interneuron

which is the correct path that a nerve impulse will follow in a reflex arc?

• motor neuron--> interneuron--> sensory neuron

• interneuron--> motor neuron --> sensory neuron

• motor neuron--> sensory neuron--> interneuron

true or false

Sensory neurons carry impulses from the brain

and the spinal cord to muscles and glands

• true

• false
