Week 1- Macroscopic Neuroanatomy Flashcards
How many nerve roots are in the cerviacal spine
8
How many nerve roots are from the thoracic
12
How many nerve roots are from the lumbar
5
How many nerve roots are from the sacrum
5
Where does the spinal chord terminate
L2
Name the 4 lobes of the brain
Frontal
Parietal
Occipital
Temporal
Parietal lobe function
Sensations
Language
Perception
Body awareness
Attention
Occipital lobe function
Vision
Perception
Frontal lobe function
Voluntary movement
Expressive language
Managing higher level executive functions (plan, self control)
Temporal lobe function
Managing emotions
Retrieving and storing memories
Understanding language
Hearing
Cerebellum function
Muscle control
Balance
Movement
Posture
Name the division between frontal and parietal
Central sulcus
Name the division between frontal and temporal
Lateral fissure
Name the division between occipital and parietal
Parieto-occipital sulcus
Name the division between temporal and occipital
Preoccipital notch
Brain stem function
Consciousness
Breathing
Heart rate
Name the fluid that surrounds the brain and spinal cord
Cerebrospinal fluid CSF
It provides a cushion
How many ventricles make up the ventricular system
4
What colour is cerebrospinal fluid
Straw like colour
Yellowy
What are the ventricles of the brain
A couple of cavities within the brain responsible for the production, transport and removal of cerebrospinal fluid around the cranial cavity
What is dura
One of the layers of CT that makes up the meninges of the brain
Function of the dura
Limit rotational displacement of the brain
What are the meninges
Three layers of membrane which work to protect the brain and the spinal cord from trauma with CSF
Name the 3 layers of meninges
PIA
ARACHNOID
DURA
List the different layers and locations of meninges
Delicate inner layer + PIA matter
Web like structure filled with fluid to cushion brain = ARACHNOID
Tough outer layer= DURA matter
Where is the CSF located in the meninges
Subarachnoid space
Between ARACHNOID and PIA
Where is CSF produced
Wat cells make it
Choroid plexi located within lateral, third and fourth ventricles of brain
EPENDYMAL CELLS
Ventricles function
protection
Buoyancy
Chemical stability
What is the blood brain barrier
Mechanism by which transmission of nutrients and oxygen to the brain is carefully managed through the composition of the vessels of the brain
It prevents toxins, pathogens, inflammation, injury and disease effecting more fragile CNS tissue/brain
Mention 2 functional areas in parietal lobe
Primary somatosensory area
Primary sensory area for speech
Name 2 major sulcus of the superolateral surface of cerebrum
Central sulci
Parietooccipital sulci
Lateral sulci
List frontal functional ateas
Primary motor cortex
Preomtor
Frontal eye field
Prefrontal cortex
Brocas area
Lost occipital functional areas
Primary visual cortex
Visual assoc cortex
List temporal functional areas
Primary auditory cortex
Auditory assoc cortex
Wernicks area
Primary olfactory cortex
