1.True or false.
____ Cranial meninges are connective tissue layer that separates the brain tissue from the scalp
____ Dura mater is the toughest out the 3 meninges and contours every gyrus of cerebral cortex.
____ Arachnoid mater protects blood vessels that supply the brain
____ There is a potential space between the arachnoid and pia mater called the subarachnoid space that contains cerebrospinal fluid
____ The meningeal layer is the part of the dura mater that covers the brain and extends into the vertebral canal
____ Superior sagittal sinus which is located between the right and left cerebral hemisphere in the superior site
____ Lateral ventricles communicate with each other by the centrum pellucidum.
____ Choroid plexus is only present in ventricles 3 and 4
____ Blood Brain Barrier (BBB) is made by capillary endothelial cells surrounded by astrocytes. It allows nutrients to go in and
nourish the brain tissue and allows CO2 and waste to get out of brain tissue
____ BBB is also present in the choroid plexus.

What is the primary function of the abducens nerve?
This branch of CN V carries only sensory fibers and innervates the eye.
Nerve moves head and shoulders and innervates the sternocleidomastoid and trapezius muscles.
Which cranial nerve innervates the parotid salivary gland?
Shortest nerve of the body (number).
Trigeminal, facial, glossopharyngeal, and vagus have which type of FUNCTION?
This nerve innervates the lateral rectus muscle.
Cranial nerve responsible for equilibrium.
Damage to the optic nerve impedes what kind of primary function?
This nerve takes sensory information directly to brain without having to pass through thalamus.
A branch of the trigeminal nerve that innervates the muscles of mastication.
This is the longest nerve; it innervates the digestive system (name).
Which cranial nerve innervates muscles that help with facial expression?
These nerves are involved in gustation and digestion of food. (number)
