Neural Basis Of Behavior

Front 1

What area of the brain tends to be depleted in conservatives?

Back 1

The right entorhinal cortex (subcortical telencephalic)

Front 2

What are the two components of the peripheral nervous system?

Back 2

-Somatic Nervous system and the autonomic nervous system

Front 3

What are the three components of the Autonomic NS?

Back 3

-Sympathetic NS
-Parasympathetic NS
-Enteric NS

Front 4

The somatic NS conveys what kind of information and in what direction?

Back 4

-conveys sensory information from the internal and external environments to the CNS (afferent/input)
-conveys motor information from the CNS and to the skeletal muscles (efferent/output)

Front 5

The Autonomic NS is specialized to innervate smooth muscle. Describe which smooth muscle groups each component innervates.

Back 5

-Sym: innverates smooth muscles of the blood vessels to dilate to allow blood to flow to teh skeletal muscles. SPORT mode.
-Parasympathetic: COMFORT Mode. Innvervates smooth muscles involved in peristalsis of the GI tract to digest food and constricts blood vessels leading to peripheral body parts
-enteric - maintains the smooth muscle of the gut
