A+P Test 3 Flashcards
Brain
Function:Brain
Controller/coordinator of body
functions
Cerebral hemispheres
Function: Cerebral hemispheres
Motor and sensory function,
memory, regulation of neural
control, emotions, etc.
Frontal lobe
Function:Frontal lobe
Actions”, motor control,
planning, motivation
Region
Cerebral hemispheres
Ends caudally at central sulcus
Parietal lobe
Function: Parietal lobe
Sensory control, language
processing, spatial orientation
Region: Parietal lobe
Cerebral hemispheres
Begins rostrally at central sulcus
Temporal lobe
Function: Temporal lobe
Emotion/memory,
auditory/visual processing
Region: Temporal lobe
Cerebral hemispheres
Most lateral lobe of cerebrum,
separated from frontal lobe by a
lateral sulcus
Occipital lobe
Function:Occipital lobe
Visual processing
Region:Occipital lobe
Cerebral hemispheres
Most caudal lobe of cerebrum
Precentral gyrus
Function: Precentral gyrus
Primary motor cortex
Region: Precentral gyrus
Frontal lobe
Most caudal part of frontal lobe
Central sulcus
Region :Central sulcus
Between frontal and parietal
lobe
Divides motor cortex from sensory cortex
Postcentral gyrus
Function:Postcentral gyrus
Primary sensory cortex
Region :Postcentral gyrus
Parietal lobe
Most rostral part of parietal lobe
Cingulate gyrus
Function:Cingulate gyrus
Emotions/learning/memory
Region :Cingulate gyrus
Cerebral hemispheres
Visible in hemisection superor to
the corpus callosum
Corpus callosum
Function:Corpus callosum
White matter tract that bridges
left and right lobes
Region:Corpus callosum
Cerebral hemispheres
Visible in hemisection superior to
the third ventricle
Thalamus
Function:Thalamus
Regulatory core of brain,
regulates motor output and
sensory input to cerebrum,
regulates functions like sleep,
alertness, etc.
Region:Thalamus
Diencephalon (core of brain)
Visible in hemisection in lateral wall
of third ventricle.
Hypothalamus
Function:Hypothalamus
Regulates activity of pituitary
gland to integrate CNS with
endocrine organs
Region:Hypothalamus
Diencephalon (core of brain)
Visible on inferior brain and in
hemisection below thalamus
Pineal gland
Function:Pineal gland
Regulates circadian/seasonal
sleep cycles through hormones
like melatonin
Region:Pineal gland
Posterior to diencephalon
(core of brain)
Lies immediately posterior to the
third ventricle and thalamus.
Pituitary gland (hypophysis)
Function:Pituitary gland (hypophysis)
Produces hormones that
regulate blood pressure,
gonads, thyroid, and other
aspects of metabolism
Region:Pituitary gland (hypophysis)
Inferior to diencephalon (core
of brain)
Sits within the sella turcica of the
sphenoid bone. Covered by durawill
be separated from brain during
removals
Cerebellum
Function:Cerebellum
Regulation of motor function
for equilibrium, fine motor
control, motor learning, etc.
Region:Cerebellum
Inferior to cerebrum, caudal to
brainstem
Lobed, folded structure. Sits caudal
to the brainstem
Midbrain
Function:Midbrain
Visual and auditory processing,
conduction of motor and
sensory signals. Sleep and
wakefullness.
Region:Midbrain
Brainstem
Pons
Function: Pons
Conduction of motor and
sensory signals, motor and
sensory functions of head via
cranial nerves
Region: Pons
Brainstem
Medulla
Function:Medulla
Conduction of motor and
sensory signals, control of
autonomic functions of body,
motor and sensory functions of
head via cranial nerves
Region:Medulla
Brainstem
Lateral ventricles
Function:Lateral ventricles
Contains csf fluid to support
brain mechanically
Region :Lateral ventricles
Cerebral hemispheres
CSF is formed in the choroid plexus
within the lateral ventricles.
Connected to third ventricle via
interventricular foramina.
Third ventricle
Function:Third ventricle
Contains csf fluid to support
brain mechanically
Region:Third ventricle
Cerebral hemispheres and
diencephalon
Single midline ventricle, also
contains choroid plexus
Cerebral aqueduct
Function:Cerebral aqueduct
Transports CSF from third to
fourth ventricle.
Region:Cerebral aqueduct
Through brainstem to between
brainstem and cerebellum
Fourth ventricle
Function: Fourth ventricle
Contains csf fluid to support
brain mechanically.
Region: Fourth ventricle
Between cerebellum and
brainstem
Has apertures allowing CSF to the
subarachnoid space around brain
and the spinal co
