Emotion, especially fear

Amygdaloid Body

Place in order the circulation of cerebrospinal fluid.

CSF is produced by the choroid plexus in the ventricles CSF flows from the third ventricle thru the cerebral aquaduct into the fourth ventricle CSF flows thru the paired lateral apertures or the single medial aperture and into the central canal of the spinal cord CSF flows thru the subarchnoid thru the subarchnoid space and removes waste CSF flows into the archnoid villi and drains into the dural venous sinuses

Which midbrain region contains motor axons from the primary motor cortex to the spinal cord?

Cerebral peduncles

As you are reading these words on the screen, what part of your brain is allowing you to perform the complex, conscious intellectual task of reading and comprehension?

Cerebrum

Emotionally significant events

Cingulate gyrus.

Check all that are a function of the hypothalamus.

Control of autonomic nervous system Control of the endocrine system Control of emotional behavior Control of food and water intake Regulation of sleep-wake rhythms

Check all of the brain structures that are composed of white matter.

Corpus callosum Septum pellucidum Internal capsule

Control of facial muscles

Facial nerve

Voluntary motor functions

Frontal lobe

Innervates pharynx

Glossopharyngeal

Long-term memory

Hippocampus

Innervates tongue muscles

Hypoglossal nerve

In what way does the cerebellum coordinate and "fine tune" skeletal muscle movements? Check all that apply.

It stores memories of previously learned movement patterns. It regulates activity along the voluntary and involuntary motor pathways.

Processes visual input

Occipital lobe

Vision

Optic nerve

Sensory functions such as touch

Parietal lobe

Check all that are a function of cerebrospinal fluid.

Provides bouyancy to the brain Protects the brain from sudden movements Transports nutrients and chemicals to the brain, and removes waste products.

Involved with hearing and smell.

Temporal lobe

Which division of the diencephalon acts as an information filter for sensory information that is forwarded to the cerebrum?

Thalamus

Check all of the statements that apply to the subdural space.

The subdural space is between the arachnoid mater and the dura mater. The subdural space fills with fluid in the case of injury. The subdural space is a potential space.

Controls muscles of mastication

Trigeminal nerve

Controls visceral and cardiac muscle

Vagus nerve

Equilibrium and hearing

Vestibulocochlear nerve

Which of the following are PREVENTED from entering the interstitial fluid of the brain, due to the blood-brain barrier?

Waste products in the blood Some hormones

Damage to the ________ nerve may result in limited ability to move the eyeball laterally.

abducens

A functional MRI scan reveals that the left and right cerebral hemispheres are not able to communicate directly. This may indicate damage to

commissural tracts.

Identify the components of the brainstem.

midbrain pons medulla oblongata

Put the cranial meninges in order, from deep (closest to the brain) to superficial (farthest from the brain).

pia matter arachnoid matter (subdural space) dura matter

Corticospinal tracts send motor commands from the cerebral cortex to the spinal cord. Therefore, these are an example of _______ tracts.

projection
