Brain Structures
This structure connects the two cerebral hemispheres.
corpus callosum?
This lobe contains the primary motor cortex.
Frontal Lobe
These three layers protect the brain and spinal cord.
meninges
Difficulty producing speech may result from damage to this area.
Brocas Area
The brain stem consists of the midbrain, pons, and medulla oblongata.
True
The cerebellum is located under this part of the brain.
cerebrum
This brain part regulates hunger, thirst, and body temperature
hypothalamus
This fluid cushions the brain and spinal cord.
cerebrospinal fluid (CSF)
Tremors, rigidity, and slow movement are signs of this CNS disorder.
Parkinson’s disease
The hypothalamus does not play a role in emotions.
False
This part of the brain connects to the spinal cord and controls vital functions.
brain stem
The RAS helps control this daily cycle
sleep and wakefulness
This structure prevents harmful substances in the blood from entering the brain.
blood-brain barrier
Inflammation of the protective layers of the brain and spinal cord is called this.
meningitis
Cerebrospinal fluid is found in the ventricles of the brain.
True
The thalamus and hypothalamus are part of this brain region?
diencephalon
This structure coordinates voluntary movements and balance.
cerebellum
The choroid plexus produces this fluid.
What is cerebrospinal fluid (CSF)
Sudden loss of blood flow to part of the brain causes this.
Stroke
The spinal cord ends at approximately the L5 vertebra.
False (it ends at L1-L2 in adults)
These projections of neurons make up white matter in the CNS
axons
This structure processes and relays sensory information to the cerebral cortex.
Thalamus
Damage to these can lead to meningitis?
meninges
This CNS disorder is caused by the degeneration of myelin sheaths, leading to impaired neural signaling.
multiple sclerosis
Gray matter contains mainly myelinated axons, while white matter contains neuron cell bodies.
False (gray = neuron cell bodies, white = myelinated axons)
