Functional Anatomy Of The Brain Flashcards
What is the main function of the cerebrum
Coordinates voluntary movement
Which part of the cerebrum is grey matter
Cerebral cortex
What are basal nuclei
Subcortical structures found in the white matter
What is the role of basal nuclei
Voluntary/ involuntary musculoskeletal activity
What part of the brain is responsible for memory and emotions
Limbic system (collection of different regions)
What part of the cerebrum is white matter
Corpus callosum
What makes up white matter
Myelinated nerve fibres
What is the corpus callosum
Neuronal connections between the hemispheres
What are the different cortex’s found in the cerebrum
Motor cortex
Sensory cortex
Association cortex
Name the different lobes of the cerebrum
Frontal lobe
Partial lobe
Temporal lobe
Occipital lobe
What is the function of the parietal lobe
Conscious perception
What is the function of the piriform lobe
Conscious olfaction
What vesicles make up thalamus
Diencephalon
What is the function of the thalamus
Interpret senses (pain, touch, temp)
Which vesicle makes up the midbrain
Mesencephalon
What is the function of the midbrain
Auditory + visual reflex
Which part of the midbrain is the visual reflex
Rostral colliculus
What part of the midbrain is the auditory reflex
Caudal colliculus
What is the cerebral peduncle
Stalk that attaches cerebrum to brainstem
Which region of the brain does the trochlear nerve enter
Mid brain (caudal colliculus)
Which region does the oculomotor nerve enter
Cerebral peduncle
Which brain vesicle makes the pons
Ventral metencephalon
Which brain vesicle makes the cerebellum
Dorsal metecephalon
What is the function of the brain pons
Unconscious processes ex) breathing
What is the function of cerebellum
Balance
What is the function of the medulla oblongata
Regulated heart rate and breathing rate (blood pressure)
What are the meninges layers and the function
Connective tissue that surrounds brain and spinal cord
Dura mater - thick fibrous outer layer
Arachnoid layer - thin middle
Pia mater - inner vascularised layer
Where is Cerebral spinal fluid found
Subarachnoid space (between Pia mater and arachnoid layer)
What are the functions of Cerebral Spinal Fluid
Gives brain boyancy and support to protect from trauma.
Provides nutrients
What are brain ventricles
CSF filled sacs that sit deep in your brain to help with Boyancy
Where are the 1st 2 ventricles found
In the cerebral hemisphere
Where is the 3rd ventricle found
Diencephalon
Where is the 4th ventricle found
Midbrain

Vagus
Accessory
Hypoglossal
Where is blood pooled in in the brain
Cerebral arterial circle
In a dog which arteries supply the rental arterial circle
Internal carotid
Basilar artery
