  • Spinal nerves

  • sensory system

  • efferent system

Explanation

Question 2 of 13

1

The skull is the cranium.

Select one of the following:

  • True
  • False

Explanation

Question 3 of 13

1

Choose the correct statements about the skull.

Select one or more of the following:

  • It is composed of 7 laterally visible bones and one internally visible bone(ethmoid).

  • There are two frontal bones.

  • The parietal bones sit anterior to the occipital lobe/bone.

  • The temporal bones sit superior to the parietal bones.

  • The sphenoid bone cannot be completely seen from the outside of the skull, but can be seen on both sides

Explanation

Question 4 of 13

1

Which statement is false?

Select one of the following:

  • The coronal suture joins parietal and frontal bones.

  • The lambdoidal suture joins occipital and parietal bones.

  • The squamous suture links the temporal and occipital bones.

Explanation

Question 5 of 13

1

Choose the correct statements about the infantile skull.

Select one or more of the following:

  • Gaps between sutures are called fontanelles.

  • The naming conventions of the 'sutures' do not change.

  • Fontanelles allow the sutures to develop slowly so that they are structurally solid by adulthood and perform their protective function.

  • Premature closure of fontanelles and formation of sutures can lead to cognitive impairment during puberty or later in life.

Explanation

Question 6 of 13

Select one of the following:

  • There is one zygomatic bone.

  • The maxillary bone is inferior to the mandible.

  • There are four nasal bones.

  • The mandible is the largest facial bone.

Explanation

Question 7 of 13

1

Choose the false statements about the meninges.

Select one or more of the following:

  • The pia mater sits directly below the dura mater.

  • The dura mater has two layers, the first can form dural reflections.

  • There are four dural reflections which separate regions of the brain.

Explanation

Question 8 of 13

1

The venous sinus allows drainage from the brain and sits between the two layers pia mater and dura mater.

Select one of the following:

  • True
  • False

Explanation

Question 9 of 13

1

Which statement about the arachnoid layer is false?

Select one of the following:

  • It contains blood vessels

  • It extends into the sulci

  • It has granulations/villi which perforate the dura to allow CSF drainage via the venous sinus

Explanation

Question 10 of 13

1

Select one of the following:

  • True
  • False

Explanation

Question 11 of 13

1

Choose the correct statements about the ventricular system?

Select one or more of the following:

  • CSF is produced by special tissue, the choroid plexus, which lines the ventricles.

  • There are two lateral ventricles, which connect to the third ventricle via the cerebral aqueduct.

  • The third ventricle is superior to the fourth ventricle.

  • The cerebral aqueduct connects to the central canal.

  • CSF leaves to the sub-arachnoid space via the lateral apertures.

Explanation
