NBL 355 - Quiz #1 questions with correct answers
What are the three functions of the nervous system? Correct Answer-
receives/detects sensory input, processes/integrates/stores information,
and produces responses and behavior
What are the main anatomical components of the nervous system?
Correct Answer-CNS and PNS
What is the CNS? Correct Answer-brain and spinal cord
What are the divisions of the PNS? Correct Answer-somatic, autonomic,
and enteric nervous systems
Describe the somatic nervous system. Correct Answer-the somatic
nervous system is split into afferent (sensory) and efferent (motor)
divisions; it produces voluntary movement via the skeletal muscles and
mediates conscious sensation
Describe the autonomic nervous system. Correct Answer-the autonomic
nervous system is split into afferent (sensory) and efferent (motor)
divisions; it produces involuntary control of smooth and cardiac muscle
and gland secretions and mediates unconscious sensation from viscera
and tissue
What are the divisions of the efferent autonomic system? Correct
Answer-parasympathetic (rest and digest) and sympathetic (fight or
flight)
, What is the enteric nervous system? Correct Answer-part of PNS located
in the digestive tract
What does gray matter contain? Correct Answer-neuronal cell bodies,
dendrites, synapses, gray matter astrocytes (glia), and blood vessels
(which give it color)
What does white matter contain? Correct Answer-myelinated axons,
oligodendrocytes, white matter astrocytes (glia), and blood vessels
What are the two types of gray matter? Correct Answer-cortex/cortical
and nuclear
Where is cortical gray matter found? Correct Answer-cerebral and
cerebellar cortex
What is the majority of the cerebral cortex? Correct Answer-neocortex
Define neocortex Correct Answer-evolved in mammalian evolution; has
6 layers
Where are nuclei found? Correct Answer-subcortical cerebral white
matter, basal ganglia, amygdala, thalamus, hypothalamus, brain stem,
and spine
