Vocab Quiz 5 Flashcards
Cerebral Angiography
inject radio-opaque dye into cerebral artery
Computed Tomography (CT)
3D representation of brain compiled from many X-rays
Magnetic Resonance Imaging (MRI)
measures waves that hydrogen atoms emit when they are activated by radio-frequency waves in a magnetic field
Positron emission tomography (PET)
images brain activity rather than structure
Functional MRI (fMRI)
measures increases in oxygen flow to different brain regions.
Basal Ganglia
A group of structures below the cortex involved in motor, cognitive and emotional functions.
Basilar Artery
Located at the base of the skull, the basilar artery is a large, specialized blood vessel that supplies oxygenated blood to the brain and nervous system.
Blood-Brain Barrier
A protective barrier that separates the brain from the blood circulating across the body. The blood-brain barrier is semipermeable, meaning it allows the passage of water as well as molecules like glucose and other amino acides that help promote neural function.
Brain-derived neurotropic factor (BDNF)
Sometimes referred to as “brain fertilizer” BDNF is a protein that helps promote the growth, maintenance, and survival of neurons.
Brain Stem
A primitive part of the brain that connects the brain to the spinal cord, the brain stem controls functions basic to survival, such as heart rate, breathing, digestive processes, and sleeping.
Broca’s area
Discovered by French physician Paul Broca in the late 19th century, this small region of the frontal lobe has been linked to speech production.
Central Sulcus
The primary groove in the brain’s cerebrum, which separates the frontal lobe in the front of the brain from the parietal and occipital lobes in the rear of the brain.
Cerebellar Artery
The major blood vessel providing oxygenated blood to the cerebellum.
Cerebellum
A brain structure located at the top of the brain stem that coordinates the brain’s instructions for skilled, repetitive movements and helps maintain balance and posture. Research suggests the cerebellum may also play a role, along with the cerebrum, in some emotional and cognitive processes.
Cerebrum
The cerebrum is the largest brain structure in humans, accounting for about two-thirds of the brain’s mass and positioned over and around most other brain structures. The cerebrum is divided into left and right hemispheres, as well as specific areas called lobes that are associated with specialized functions.
