Week 2 - WET + DRY Flashcards
What kind of fibres pass through the corpus callosum?
Commisural
Label the rostrum, genu, body, splenium of the corpus callosum.
What thin sheet seperates the anterior horns of the two lateral ventricles?
Septum pellucidum
What is the main function of the hypothalamus?
Neuroendocrine role
More specificly :
Hormone production
Regulation of body tempurature
Regulation of behaviour/emotions
Where are the colliculi (a component of the midbrain) in relation to the pineal gland?
Inferior
What structures constitute the basal ganglia?
Caudate
Putamen
Globus Pallidus
Substantia Nigra
Sub-thalamic Nuclei
The internal capsule is made up of white or grey matter?
White matter (myelinated axons)
What is the name given to the fibres that connect the cerebral hemispheres with other parts of the brain?
Association
The internal capsule is made up of an anterior limb, genu and a posterior limb. Identify these on a diagram.
Which cerebral artery through one of its branches supplies the internal capsule?
Middle cerebral
in the midbrain, where would the red nucleus be in relation to the substantia nigra, anterior or posterior to it?
Posterior
Identify the part of the midbrain called as the cerebral peduncles. What fibres does it contain?
Projection -consist of efferent and afferent fibers uniting the cortex with the lower parts of the brain and with the spinal cord.
What fibres make up the pyramids of the medulla?
Motor fibres - corticospinal tract
List the features that can be used to identify the region of spinal cord each section comes from.
Cervical - mostly white matter
Thoracic - lateral horns in grey matter
Lumbar - process of elimination
Sacral -mostly grey matter
Which aspect of the spinal cord receives sensory nerve fibres?
Dorsal horn
From which aspect of the spinal cord do motor nerve fibres project?
Ventral horn
