NEUROSCIENCE EXAM #1 DRQ
QUESTIONS AND ANSWERS
What does the PNS consist of? - Answer-All nerves outside of the CNS.
How are the CNS and PNS related? - Answer-The PNS has afferent and efferent
pathways that both provide the CNS with sensory input and carries out the
commands of the CNS.
What is the difference between the ANS and SNS? - Answer-SNS associated with
voluntary movements while ANS involved with automatic processes such as heart
rate and digestion.
How does the ANS and SNS interact with the CNS/PNS? - Answer-SNS and ANS
subdivisions of the PNS. PNS utilizes the nerves in the SNS and ANS to relay
messages (afferent/efferent) to and from the CNS.
Superior/Inferior, Anterior/Posterior, Rostral, Dorsal/Ventral and Caudal - Answer-
The six major directional terms
Medial - Answer-Toward the midline
Lateral - Answer-Away from the midline
Proximal - Answer-Closer
Frontal Lobe - Answer-Higher order thinking such as problem solving and planning
ahead
Parietal Lobe - Answer-Regulates motor control and attention
Temporal Lobe - Answer-Major role in language processing, hearing and memory
Occipital Lobe - Answer-Processes visual information
Meninges - Answer-Protects the CNS and restricts the movement of the brain. (Dura
Mater, Archnoid Mater & Pia Mater)
Gyrus - Answer-The ridges of the brain
Sulcus - Answer-The Grooves
Fissure - Answer-Deeper versions of sulci
What blood vessels are responsible for providing blood flow to the surface of the
brain? - Answer-Anterior, middle and posterior arteries
