6 250 EXAM QUESTIONS GRADED A+
The answer appears before the question
Arachnoid mater
During a lumbar puncture, cerebrospinal fluid (CSF) is collected for diagnostic
purposes. The needle passes
through the thin meninge with hair-like extensions of tissue that contains CSF in
the space beneath it. Which
meningeal layer is this?
Arachnoid mater
Dura mater
Pia mater
False
T/F Sulci are deep grooves in the brain that separate large regions such as the
cerebral hemispheres.
Children and sometimes in adults during concentration
Theta waves are typically observed in:
-Comatose patients with no brain activity
-Adults when they are asleep
-Children and sometimes in adults during concentration
,-Adults when they are deeply relaxed with their eyes closed
-All individuals during periods of extreme mental focus
label the brain
parietal lobe
Processes sensory input from the body
fontal lobe
Functions in decision making and personality
temporal lobe
Involved in processing auditory information
occipital lobe
Responsible for visual processing
Lateral sulcus
Which sulcus separates the temporal lobe from the frontal and parietal lobes?
Longitudinal fissure
Transverse cerebral fissure
Lateral sulcus
Parieto-occipital sulcus
Cauda equina
,Nerves that continue past the conus medullaris and resemble a horse's tail are
known as the:
Ventral roots
Central canal
Filum terminale
Denticulate ligaments
Cauda equina
False
T/F Ascending tracts carry motor impulses from the brain to the periphery.
Pia mater
What meningeal layer remains intact and clings tightly to the surface of the
sheep brain?
Dura mater
Gray matter
Pia mater
White matter
Arachnoid mater
Sensory function
, What type of loss of function would result if the dorsal root were damaged?
Reflex function
Motor function
Sensory function
Balance control
Coordinated movement
inferior colliculus
A patient has difficulty with auditory reflexes after head trauma. Imaging shows
damage to a brain structure
within the midbrain. What structure has been affected?
True
T/F The central nervous system (CNS) can send and receive signals to and from
the peripheral
nervous system (PNS).
The depolarization of the membrane to the threshold at the axon hillock.
The initiation of an action potential depends on:
-Stabilization of the membrane at its resting potential.
-The hyperpolarization of the axon.
