Anatomy of Brain Continued Flashcards
when a rupture in an artery allows blood to leak into the brain
Hemorrhagic Stroke
clots or other debris prevent blood from reaching a region of the brain, causing it to die
Ischemic Stroke
is caused by the rupture or blockage of blood vessels, leading to insufficient oxygen supply
Stroke
derived fluids during sleep
- Besides CSF, the brain depends on an ample supply of oxygenated blood from the cerebral arteries
The brain has a Glymphatic System that drains waste in CSF
- Provides nutrients to the brain
- Allows for exchange of nutrients with the blood system
- Acts as a buffer/cushion for the brain
- Picks up waste material
The Ventricular System is a series of chambers filled with CSF
is an acute infection of the meninges
Meningitis
lies between the other two; filled with cerebrospinal fluid (CSF)
Arachnoid Membrane
delicate innermost layer
Pia Mater
tough outermost layer
Dura Mater
marks transition from brain to spinal cord; drives essential processes such as respiration and heart rate; origin of some cranial nerves
Medulla
contains sensory and motor nuclei; origin of some cranial nerves
Pons
attached to the brainstem; crucial for motor coordination and control; participates in some types of learning
Cerebellum
auditory processing
Inferior Colliculi
visual processing
Superior Colliculi
contains nuclei with many functions; extremely important in hormone release
Hypothalamus
a cluster of nuclei that relay sensory information
Thalamus
sense of smell
Olfactory Bulb
attention
Cingulate Gyrus
learning and memory
Hippocampus and Fornix
emotional regulation and perception of odor
Amygdala
structures important for emotion and learning
limbic system
important in motor control and consist mainly of the caudate nucleus, putamen, and globus pallidus
basal ganglia
body parts on the same side of the body or in reference to a given point
Ipsilateral
