Worked practice questions

In Hydra, the neural system is composed of

  1. A network of neurons
  2. A dorsal nerve cord
  3. A ventral nerve cord
  4. A brain and ganglia
Show answer and solution

Correct answer: A. A network of neurons

Hydra has a very simple neural organisation made of a diffuse network of neurons with no brain.

Afferent nerve fibres carry impulses in which direction?

  1. Between two motor neurons
  2. From the CNS to muscles
  3. From the CNS to glands
  4. From tissues to the CNS
Show answer and solution

Correct answer: D. From tissues to the CNS

Afferent fibres bring impulses from tissues and organs into the CNS.

Impulses from the CNS to involuntary organs and smooth muscles travel through the

  1. Afferent fibre system
  2. Somatic neural system
  3. Central neural system
  4. Autonomic neural system
Show answer and solution

Correct answer: D. Autonomic neural system

The autonomic division of the PNS sends impulses to involuntary organs and smooth muscles.
