1Between T1 and L2 the vertebral grey matter contains 'lateral horns'. What is contained within these lateral horns?
- AParasympathetic Pre-Ganglionic Neurons
- BParasympathetic Post-Ganglionic Neurons
- CSympathetic Pre-Ganglionic Neurons
- DSympathetic Post-Ganglionic Neurons
2Match the definitions to the term they describe.
[blank_start]Ganglion[blank_end] A group of nervous cells residing outwith the central nervous system
[blank_start]Nucleus[blank_end] A group of nervous cells residing within the central nervous system- AGanglion
- BNucleus
- CNeuron
- DTract
3There are three major longitudinal arteries that supply the spinal cord: The 2 [blank_start]Posterior Spinal[blank_end] Arteries and the 1 [blank_start]Anterior Spinal[blank_end] Artery.
- APosterior Spinal
- BAnterior Spinal
4Unlike the dura in the cranial cavity, the dura in the spinal canal is not directly in contact with the bone. This space is called the [blank_start]Epidural[blank_end] space and is useful for anaesthesia.
- AEpidural
5Within the epidural space run a network of venous plexuses to drain the blood from the spinal cord. These are called [blank_start]Epidural[blank_end] venous plexuses.
- AEpidural
6Label the below diagram
- APrimary Somatosensory Cortex
- BPrimary Motor Cortex
- CCentral Sulcus
- DPrimary Somatosensory Cortex
- ECentral Sulcus
- FPrimary Motor Cortex
- GPrimary Somatosensory Cortex
- HPrimary Motor Cortex
- ICentral Sulcus
7The main sensory system responsible for fine touch and proprioception sensations is called the ...
- ADorsal Column/Medial Lemniscus System
- BSpinothalmic Tract
- CCorticospinal Tract
- DTectospinal Tract
8In terms of the dorsal column/medial lemniscus system, sensory nerve impulses first enter the spinal cord via the [blank_start]dorsal[blank_end] root (dorsal or ventral?) before synapsing in the [blank_start]Medulla[blank_end], from which they then travel up into the brain, synapsing again in the [blank_start]Thalamus[blank_end] before finishing their journey at the [blank_start]Somatosensory[blank_end] Cortex
- Adorsal
- BMedulla
- CThalamus
- DPrimary Somatosensory
9The [blank_start]Spinothalamic[blank_end] Tract is responsible for the sensory aspect of the pain sensation
- ASpinothalamic
10The [blank_start]Corticospinal[blank_end] Tract is the main Motor Pathway allowing fine and precise movements.
- ACorticospinal
- BTectospinal
- CReticulospinal
- DVestibulospinal
11An Upper Motor Neuron lesion is classed as a lesion anywhere between the [blank_start]Cortex[blank_end] and the [blank_start]Anterior Horn of vertebral grey matter[blank_end].
- ACortex
- BMedulla
- CPons
- DAnterior Horn of vertebral grey matter
- EPosterior Horn of vertebral grey matter
- FSpinal Nerve
- GAnterior Rami
- HMuscle
12The Corticospinal Tract is also known as the [blank_start]Pyramidal[blank_end] Tract
- APyramidal
13The decussation of the pyramids refers to the point at which around 85% of the fibres of the corticospinal tract cross from one side to the other. This occurs in the [blank_start]Medulla[blank_end].
- AMedulla
- BPons
- CMidbrain
- DPrimary Motor Cortex
- EAnterior Horn of Vertebral Grey Matter
14Name the white matter tract used by the Corticospinal Tract to pass neurons from the Primary Motor Cortex into the Midbrain
The [blank_start]Internal Capsule[blank_end]- AInternal Capsule
15Match each aspect of the extra-pyramidal system to its definition.
[blank_start]Tectospinal Tract[blank_end] Mostly serves the cervical area, mediating head and neck reflex movements in response to visual and auditory stimuli
[blank_start]Reticulospinal Tract[blank_end] Forms the central core of the brainstem, has many nuclei and receives input from virtually all parts of the CNS
[blank_start]Vestibulospinal Tract[blank_end] Maintains head and eye coordination, upright posture and balance.- ATectospinal Tract
- BReticulospinal Tract
- CVestibulospinal Tract
16Which Corticospinal tract crosses over in the medulla at the decussation of the pyramids?
- AThe Lateral Corticospinal Tract
- BThe Ventral (Anterior) Corticospinal Tract
17In terms of the spinal cord itself, what fibrous structure is the yellow arrow on the diagram pointing to?
[blank_start]Filum Terminale[blank_end]
- AFilum Terminale
18The [blank_start]Denticulate[blank_end] Ligaments are extensions of the pia mater over the spinal cord which holds the spinal cord in place, by connecting the pia mater to the arachnoid & dura maters.
- ADenticulate
