Macroscopic Anatomy Flashcards
what are the four lobes of the brain
frontal, parietal, occipital, frontal
what are the 4 important sulci called
pre central sulcus
post central sulcus
parieto-occipal sulcus
lateral sulcus
what are the 3 functionally different areas the cortex
sensory, motor, associative
what is the function of the frontal lobe
movement, problem solving, personality, behaviour, mood
what is the function of the parietal lobe
sensations, language, perceptions
what is the function of the occipital lobe
vision
what is the function of the temporal lobe
hearing, language, memory
what is the function of the cerebellum
posture, balance, coordination
what is the function of the brain stem
consciousness, breathing, heart rate
what are the 5 layers of the scalp
Skin
subcutaneous Connective tissue
galea Aponeurotica
Loose areolar connective tissue
periosteum
what are the meninges
3 protective layers of tissue to protect the brain from trauma with CSF
what are the 3 protective layers of the meninges
Pia mater
arachnoid mater
dura mater
where do the meninges sit in context
deep to the skull
between what layers is CSF present
epidural space
subdural space
subarachnoid space
where is the epidural space
between the skull and dura mater
what artery enters the skull through the foramen spinosum and the epidural space
middle meningeal artery
where is the subdural space
between inner layer of dura and arachnoid mater
which veins travel through the subdural space
bridging veins
what is inside the subarachnoid space
arachnoid trabecular, blood vessels and CSF
what is the ventricles of the brain
set of communicating cavities in the brain
what is the function of the ventricles in the brain
protection - cushioning effect
buyoancy
chemical stability
what are the ventricles responsible for
responsible for the production, transport and removal of CSF
name the 4 ventricles
1 lateral ventricle
2 lateral ventricle
3rd ventricle
4th ventricle
What is the blood brain barrier
A mechanism by which transmission of nutrients and oxygen to the brain is carefully managed through vessels in the brain
