Lab 1 Exam option 1

What occurs when the brain is without blood flow for 2 minutes?

A person will pass out and neural activity will be impaired.

These ventricles are in the cerebral hemispheres.

A) Lateral

Damage to both nerve branches is fatal.

Bilateral damage to the cranial nerve highlighted in blue, above causes:

drooping eyelid, eyeball to rest laterally

Damage to the cranial nerve (highlighted in blue) causes: ____.

E) Deafness Nerve deafness-auditory branch

Damage to the cranial nerve highlighted in blue, causes:

Nystagmus

Damage to the cranial nerve in blue causes:

ataxic movement

Damage to the region (pin) causes what movement disorder?

sulcus (sulci)

Grooves above pin

Interpreting of general senses

Injury to the area of the brain (blue arrow) would most likely cause impaired

Motor planning

Injury to this area would most likely cause impaired...?

What occurs when the brain is without blood flow for 10 seconds ?

Loss of consciousness

Name the sensory only branches of the cranial nerve highlighted in blue

Ophthalmic branch & maxillary branch

central sulcus

The blue line in the picture is called

eyes to move laterally

The cranial nerve (highlighted in blue) enables what movements?

A) the largest cranial nerve. B) Correct! has a motor branch enabling facial expressions. C) has a motor branch that causes the gag reflex. D) has a sensory branch detecting gastrointestinal discomfort. E) has a sensory branch detecting balance.

The cranial nerve highlighted in blue

gyrus (gyri)?

The folds in the region above (blue pin) are called:

When protruding the tongue, it will deviate to the left.

The left cranial nerve (highlighted in blue) was damaged. How would this present during a physical examination?

chewing.
