Parts of the Brain
The brain is divided into four major parts including the cerebrum, cerebellum, and diencephalon. What is the fourth?
The Brainstem
This major part of the brain is associated with the coordination of movement.
The cerebellum
What layer of the three cranial meninges is divided into two layers, and what are they?
They dura mater is divided into the periosteal and meningeal layer
What are the four lobes of the brain?
Frontal, parietal, temporal, and occipital
How many cranial nerve pairs are there?
Twelve (12)
What are the three layers of the cranial meninges (in order)?
The dura mater, the arachnoid mater, and the pia mater.
Which major area in the brain is considered the major "relay station" for sensory impulses?
The thalamus
The medulla oblongata is located in this part of the brain.
The brainstem
What lobe of the brain is associated with the primary auditory cortex?
Temporal lobe
What is the largest cranial nerve?
The Trigeminal nerve (three branches: ophthalmic, maxillary, and mandibular)
This part of the brain allows for the controlled passage OR blockage of certain substances to the brain.
The blood brain barrier (BBB)
The occipital lobe is associated with sensory pathways for what sense?
Vision (Primary Visual Cortex)
The diencephalon consists of the thalamus, epithalamus, and this third structure that is associated with emotional behavior, body temperature regulation, and satiety.
The hypothalamus
What lobe of the brain is associated with the primary motor cortex?
Frontal lobe
What cranial nerve axons end in the olfactory (smell) cortex in the temporal lobe of the cerebrum?
CN I: OLFACTORY nerve
Where is cerebrospinal fluid (CSF) found?
The subarachnoid space
Broca's area is associated with nerve impulses that control speaking. Damage to this region of the brain results in what type of aphasia?
Nonfluent aphasia (clear thoughts, but cannot form words)
The primary somatosensory cortex is a sensory area of the cerebrum located in this lobe of the brain.
Parietal lobe
What of the four lobes of the brain is the largest?
The Frontal Lobe
What three cranial nerves are associated with extraocular eye movements (control muscles that move the eyeballs)?
CN III: The Oculomotor Nerve, CN IV: The Trochlear Nerve, and CN VI: The Abducens Nerve
The medulla oblongata is lectured about in what movie?
Water Boy
Each hemisphere of the brain specializes in performing certain functions. This is called what?
Hemispheric lateralization
What is the largest white matter structure that connects the two hemispheres of the brain and allows for communication?
The corpus collosum
This mixed cranial nerve senses from the anterior 2/3 of the tongue from the taste buds to the gustatory areas in the brain
CN VII: Facial Nerve
