1The dorsal white columns are a part of:
- APNS
- BSpinal nerves
- Csensory system
- Defferent system
2The skull is the cranium.
- AVerdadero
- BFalso
3Choose the correct statements about the skull.
- AIt is composed of 7 laterally visible bones and one internally visible bone(ethmoid).
- BThere are two frontal bones.
- CThe parietal bones sit anterior to the occipital lobe/bone.
- DThe temporal bones sit superior to the parietal bones.
- EThe sphenoid bone cannot be completely seen from the outside of the skull, but can be seen on both sides
4Which statement is false?
- AThe coronal suture joins parietal and frontal bones.
- BThe lambdoidal suture joins occipital and parietal bones.
- CThe squamous suture links the temporal and occipital bones.
5Choose the correct statements about the infantile skull.
- AGaps between sutures are called fontanelles.
- BThe naming conventions of the 'sutures' do not change.
- CFontanelles allow the sutures to develop slowly so that they are structurally solid by adulthood and perform their protective function.
- DPremature closure of fontanelles and formation of sutures can lead to cognitive impairment during puberty or later in life.
6There are 14 facials bones, but only seven are visible. Which statement about the visible facial bones is true?
- AThere is one zygomatic bone.
- BThe maxillary bone is inferior to the mandible.
- CThere are four nasal bones.
- DThe mandible is the largest facial bone.
7Choose the false statements about the meninges.
- AThe pia mater sits directly below the dura mater.
- BThe dura mater has two layers, the first can form dural reflections.
- CThere are four dural reflections which separate regions of the brain.
8The venous sinus allows drainage from the brain and sits between the two layers pia mater and dura mater.
- AVerdadero
- BFalso
9Which statement about the arachnoid layer is false?
- AIt contains blood vessels
- BIt extends into the sulci
- CIt has granulations/villi which perforate the dura to allow CSF drainage via the venous sinus
10The pia mater is the most delicate of the meninges, adhering closely to the brain's surface. It is also the only layer which extends into the sulci.
- AVerdadero
- BFalso
11Choose the correct statements about the ventricular system?
- ACSF is produced by special tissue, the choroid plexus, which lines the ventricles.
- BThere are two lateral ventricles, which connect to the third ventricle via the cerebral aqueduct.
- CThe third ventricle is superior to the fourth ventricle.
- DThe cerebral aqueduct connects to the central canal.
- ECSF leaves to the sub-arachnoid space via the lateral apertures.
12A [blank_start]blockage[blank_end] in the [blank_start]ventricles[blank_end] increases intracranial pressure. In infants and young children who still have [blank_start]fontanelles[blank_end], this can result in swelling of the ventricles and [blank_start]brain[blank_end] leading to progressive enlargement of the [blank_start]head[blank_end]. Other symptoms include convulsion, tunnel vision, and mental disability.
- Ablockage
- Bventricles
- Cfontanelles
- Dhead
- Ebrain
13Which statement about the dural reflections is correct?
- AThe falx cerebri separates the cerebellar hemispheres.
- BThe falx cerebelli separates the cerebral hemispheres.
- CThe falx cerebelli sits in the lateral plane.
- DThe tentorium cerebelli sits in the horizontal plane.
