the brain Flashcards
what is the cerebrospinal fluid
ultrafiltrate of plasma that surrounds the brain and spinal cord
what are the main functions of the cerebrospinal fluid
protection
buoyancy
chemical stability
what are the ventricles of the brain
these are the structures responsible for producing cerebrospinal fluid
what lines the ventricles of the brain
ependymal cells
what are the four ventricles of the brain
- right lateral
- left lateral
- third ventricle
- fourth ventricle
what connects the lateral ventricles to the third ventricle
foramen of monro
where is the third ventricle in the brain
situated between the right and left thalamus
how does the fourth ventricle receive CSF
from the third ventricle via the cerebral aqueduct
where is the fourth ventricle of the brain
within the brainstem
what produces the CSF
choroid plexus
where is the choroid plexus
within the lining of the ventricles
what are the lobes of the brain
frontal lobe
temporal lobe
parietal lobe
occipital lobe
which lobe is responsible for perceiving sounds, assigning meaning and remembering them
the temporal lobe
what is the function of the temporal lobe
auditory processing
what is the function of the occipital lobe
processes what we see
which lobe of the brain is responsible for recognising colours, shapes, faces and movements
the occipital lobe
which lobe of the brain is described as the visual brain
the occipital lobe
what is the function of the parietal lobe
process sensory information for understanding numbers, objects and spacial relations
which lobe of the brain is responsible for spacial reasoning
the parietal lobe
what is the function of the frontal lobe
voluntary movement, speech, attention, reasoning, problem solving, impulse control, memory and emotional expression.
which lobe of the brain is responsible for personality
the frontal lobe
what is the function of the cerebellum
coordination, precision, balance and posture
what is the function of the medullary oblongata
involuntary functions like breathing and heart rate
what are the areas of the brain
cerebrum
ventricles
hypothalamus
pituitary gland
pons
medulla
cerebellum
midbrain
brainstem
thalamus
corpus callosum
what is the brain divided into
two hemispheres - left and right
what are the two hemispheres each divided into
the four lobes
what connects the two hemispheres of the brain
corpus callosum
what is brocas area
section of the frontal lobe responsible for language production
what is wernickes area
the section of the temporal lobe essential for understanding speech
which side of the body does the left hemisphere control
the right side
which side of the body does the right hemisphere control
the left
what is the lateral sulcus
a deep fissure in each hemisphere that separates the frontal and parietal lobes from the temperol lobe
what is the precentral gyrus
an elevated bridge of brain tissue that executes voluntary movements
what does the post central gyrus do
the somatosensory cortex where the body’s sensory inputs like touch pain and temperature are registered
what does the left hemisphere specialise in
language and speech
what does the right hemisphere specialised in
visual and spatial skills
what is the pons
the largest part of the brainstem between the midbrain and the medulla oblongata. it is a group of nerves that function as connection between the cerebrum and the cerebellum
what is cerebral cortex
the gray matter that forms the outermost layer of nerve tissue in the brain and is what is then separated into the lobes
what is the central sulcus
groove separating the frontal lobe from the parietal lobe
