Patho Exam 6 - Module 12: Neuro Verified
and Updated Questions and Answers (100%
Correct Answers)
Central nervous system: basic structure
Answer: -brain and spinal cord responsible for receiving and processing
information, and creating coordinated responses
-Cerebrospinal fluid surrounds the brain and spinal cord for protection
-The BBB separates and shields the CNS from the body's periphery
Forebrain:
Answer: telencephalon and diencephalon
Midbrain:
Answer: connects forebrain and hindbrain, contains red nucleus and substantia
nigra
Hindbrain:
Answer: cerebellum, pons, medulla oblongata
Spinal cord:
Answer: one long nerve starting from the medulla oblongata and ends between the
first and second lumbar vertebrae
Afferent:
Answer: sensory nerve pathways,, ascending, carry info from periphery to central
NS
Efferent:
Answer: motor nerve pathways, from CNS to PNS
Differentiate between white and gray matter
Answer: -White matter contains spinal tracts
-The grey matter creates a hornlike structure throughout the inside of the spinal cord
while the white matter makes up the surrounding sections of the spinal cord.
-The grey matter does extend to the spinal cord to make signaling more effective.

Describe the structures necessary for reflexes
Answer: Receptor, afferent neuron, efferent neuron, and a muscle or gland
Autonomic nervous system
Answer: -Sympathetic
-Parasympathetic
-Identify neurotransmitters of the ANS, including which are preganglionic and which
are post ganglionic
Cell body:
Answer: -also known as the soma, which is located mainly in the central nervous
system.
-Dense groupings of cell bodies in the central nervous system are known as nuclei.
-Cell bodies found in the peripheral nervous system are called ganglia.
Dendrites:
Answer: the receptive portion of the neuron and carries nerve impulses toward the
cell body
Axons
Answer: are long conductive projections that generate and conduct action
potentials. Axons carry nerve impulses away from the cell body
Neuroglia:
Answer: support the neurons of the central nervous system
Oligodendroglia:
Answer: cells that form the myelin sheaths within the brain and spinal cord
Schwann Cells:
Answer: form the myelin sheath around axons in the peripheral nervous system
Non-myelinating Schwann Cells:
Answer: help provide metabolic support
Myelinating vs non-myelinating
Answer: Myelinated axons are the neuron axons which are covered with myelin
sheaths. Unmyelinated axons are the axons which are not covered with myelin
