All of the structures of the CNS originate from the
Neural tube
The primary brain vesicles in which the neural tube is divided into are:
Prosencephalon - Mesencephalon - Rhombencephalon
The medulla oblongata and the pons are structures in the CNS or PNS?
Central Nervous System
Which structure would be most active if you were in a hot, dry desert without water?
Diencephalon (hypothalamus)
In which type of neurons do impulses move fastest?
myelinated neurons
Which are the components of the PNS?
Cranial nerves, Spinal nerves, Ganglia
To which primary brain vesicle is the medulla oblongata a part of?
rhombencephalon
Which area regulates sleep, food intake, and endocrine (hormone) functions?
Diencephalon
Is the cerebellum part of the brain stem?
No
Which brain region regulates blood pressure, breathing, and swallowing, acting as an autonomic reflex center of the brain?
Medulla oblongata
Are cranial nerves part of the brain?
No
Brain region where the corticospinal tracts cross the midline to the opposite side of the body.
Medulla oblongata
Why is the cerebral cortex known as gray matter?
Because it contains unmyelinated neuron cell bodies.
Brain region that controls visual reflexes that coordinate head and eye movements when we follow a moving object.
midbrain
Relaying information from the cerebrum to cerebellum is a function of the:
pons
In adult humans, what percentage of the body’s neural tissue does the brain contain?
97%
