Math synonymous terms when describing directionality in the spinal cord Inferior: Superior:

Inferior: Caudal Superior: Rostral

Cerebral spinal fluid is produced in the choroid plexus of ventricles with helps to drive the pressure gradient that circulates CSF. Which of the following correctly describes the path of CSF fluid circulation

Lateral ventricles--> foramen of Monro--> third ventricle--> cerebral aquaduct--> fourth ventricle--> foramen of Luschka and Magendie--> subarachnoid space

This is the order from the most inferior to most superior of the components of the brainstem:

Medulla, pons, midbrain

Dynamic neuroimaging technique that measures glucose dependent metabolic activity by using a radioactive tracer. Neuroimaging technique that is static and uses an electromagnetic field and radio frequencies. This method provides a good amount of detail, but is sometimes still not sensitive enough to pick up on early onset neurological diseases like dementia. Neuroimaging technique that is static and uses x-rays. This method is sensitive to tissue density changes.

PET MRI CT

Considered the system that calms, conserves, and restores energy. When active, this system slows heart rate and increases digestion

Parasympathetic nervous system

Match Primary auditory processing cortex: Primary visual processing cortex:

Primary auditory processing cortex: temporal lobe Primary visual processing cortex: Occipital lobe

Which lobes holds the following cortex? Primary somatosensory cortex: Primary motor cortex:

Primary somatosensory cortex: parietal lobe Primary motor cortex: frontal lobe

Which of the following make up the central nervous system (CNS)? Spinal cord Brain Cranial Nerves Spinal Nerves

Spinal cord & brain

These control motor & sensory function below the neck

Spinal nerves

The peripheral nervous system (PNS) includes which of the following : Spinal nerves, cranial nerves, spinal cord

Spinal nerves & cranial nerves

Considered the "fight, flight, or freeze" system. When activated, accelerates heart rate, constricts peripheral blood vessels, raises blood pressure, and diverts blood to the brain, heart and skeletal muscles

Sympathetic nervous system

Match The internal carotid branches into these arteries that project superiorly from the circle of willis The basilar artery branches into the ____

The internal carotid branches into these arteries that project superiorly from the circle of willis: Anterior & middle cerebral arteries The basilar artery branches into the ____: posterior cerebral artery

An SLP should evaluate for speech & lang deficits in a patient with right arm and leg weakness following a stroke. Why?

The right arm & leg are controlled contralaterally by the left hemisphere of the brain which is where the speech & lang centers are.

Which of the following statements is true of the association cortices? - They are cortical areas within a hemisphere that assist in interpretation of meaning of stimuli - They connect cortical areas between the hemispheres - They connect the cerebral cortex with the spinal cord

They are cortical areas within a hemisphere that assist in interpretation of meaning of stimuli

T/F, An action potential is all or nothing

True

T/F, The diencephalon relays sensory information to and motor information from the cortex and is highly involved with autonomic, endocrine, & motor systems

True

T/F, With a few exceptions, there is bilateral muscle control for speech muscles which makes sense because speech movements need to be rapid and symmetrical in order for clear and precise sounds to be produced. Therefore, when unilateral damage occurs the effects on speech are generally mild because the other side is able to help compensate.

True

The dura mater folds in on itself to form the following a. Falx cerebri (designed to help anchor the brain to prevent damage from rotational displacement) b. superior sagittal sinus (can collect and remove blood through here in the result of an injury) c. subarachnoid space (contains complex branching of arterial systems) d. corpus callosum (commissural pathway between right and left hemispheres of the brain) e. the first and second ventricles (passageway for CSF to circulate)

a. Falx cerebri (designed to help anchor the brain to prevent damage from rotational displacement) b. superior sagittal sinus (can collect and remove blood through here in the result of an injury)

What association fiber tract connects Wernicke's area w/ Broca's area?

arcuate fasciculus

Which of the following statements are true about neurosensory organization? a. Sensory information enters the spinal cord through the ventral root b. Sensory information enters the spinal cord through the dorsal root c. Primary (1st order) neurons decussate in the spinal cord. d. Almost all sensory tracts synapse in the thalamus on their way to the cortex.

b. Sensory information enters the spinal cord through the dorsal root d. Almost all sensory tracts synapse in the thalamus on their way to the cortex.
