Major Divisons Of The Brain Flashcards
•Also called as Prosencephalon
•largest division of the brain
Forebrain
The forebrain is home to
sensory processing, endocrine structures,
and higher reasoning
plays a role in most of our
brain activity and thus is more
analogous to an entire division
of the nervous system than to a
particular delimited brain
structure
Forebrain: Telencephalon
The cerebral cortex contains folded
bulges called _____ that create
indentations in the brain.
Gyri
Functions of
the cerebral cortex include:
processing
sensory information, controlling motor
functions, and performing higher-order
functions such as reasoning and
problem-solving
The _________’s functions
primarily involve ‘higher’ cognitive functions
such as decision-making, conscious thought,
problem-solving, and attention.
frontal lobe
Responsible for receiving and
processing sensory information
Parietal Lobes
Parietal lobes
also contain the _________ ______,
which is essential for processing touch
sensations
somatosensory cortex
Occipital lobes is responsible for
receiving
and processing visual information from the
retina
Temporal Lobes: Home of the limbic system structures including the
amygdala and hippocampus
These lobes organize
sensory input, as well as aid in auditory
perception, memory formation, and language
and speech production.
Temporal Lobes
•are a group of structures near the center of your brain that form
important connections
•These connections allow different areas of your brain to work
together
Basal ganglia
The basal ganglia manage the
signals your brain sends that help you move
your muscles
is a brain structure
embedded deep in the temporal lobe
of each cerebral cortex
Hippocampus
The hippocampus is a small but
complex brain structure that plays an
important role in the
process of
learning and the formation of new
memories
The amygdala is responsible
for the ___________
such as anger, fear, and sadness,
as well as the _______________.
perception of emotions, controlling of
aggression
helps to
store memories of events and
emotions so that an individual may
be able to recognize similar events
in the future
Amygdala
is the region of the brain that relays sensory
information and connects components of the endocrine
system with the nervous system
Diencephalon
A limbic system structure that connects areas of the
cerebral cortex that are involved in sensory perception and
movement with other parts of the brain and spinal cord
Thalamus
The major functions of the __________ include
control of the pituitary gland, regulation of body temperature, food
intake, fluid intake, control of the autonomic nervous system,
control of stress, emotional expression and aggression, sleep and
waking, sexual arousal and memory
hypothalamus
Another term for midbrain
Mesencephalon
the area of
the brain that connects the forebrain
to the hindbrain
Midbrain/Mesencephalon
The midbrain and
hindbrain together compose the
Brainstem
The midbrain regulates _________
and aids in the processing of
_____________ information
movement, auditory and visual
It forms the dorsal side of the mesencephalon or midbrain.
Tectum
The midbrain tectum is
formed by two structures:
Superior and Inferior Colliculus
is a tiny structure that serves as a key reflex hub
Superior Colliculus
The inferior colliculus is made up of a single layer of neurons to which the _____________ (auditory fibers) synapses.
lateral lemniscus
The ___________ of the medulla contains the medullary reticular formation, together with cranial nerve
nuclei and ascending tracts.
tegmentum
also known as the
rhombencephalon
Hindbrain
is one of the most crucial parts of
the central nervous system (CNS) as it
connects the brain to the spinal cord so that
messages can be sent from the brain, down
the spinal cord, to the rest of the body
Hindbrain/Rhombencephalon
The hindbrain’s chief role is to _________, making the
hindbrain important for survival.
coordinate the
vital functions of our bodies, such as breathing and heart rate
The metencephalon is the upper region of the hindbrain and
contains the _______ and __________.
pons, cerebellum
The metencephalon gives rise to the cerebellum, the part of the
brain responsible for
coordinating movements, posture, and balance
is a component of the brainstem, which acts as a bridge
connecting the cerebrum with the medulla oblongata and cerebellum
Pons
relays information between muscles and areas
of the cerebral cortex that are involved in motor control.
Cerebellum
is the lower region of
the hindbrain located below the
metencephalon and above the spinal cord
Myelencephalon
The myelencephalon is the part of the ______
brain that develops into the ______________ and connects the brain to the
spinal cord.
fetal, medulla oblongata
is also known as the brain stem.
It emerges out from the base of the brain
and joins the brain to the spinal cord
Medulla oblongata
