Chapter 14 & 16 Flashcards
Somatic Sense
information about body and environment
Visceral Sense
information about internal organs
Tonic Receptors
accommodate slowly
Phasic Receptors
accommodate quickly
Primary Receptor
axons conduct action potentials in response to receptor potential
Secondary Receptor
cause release of neurotransmitter that bind to receptors on a neuron causing a receptor potential
What kind of pathway is the lateral spinothalmic tract
ascending pathway
Secondary and Tertiary neurons are
in an ascending tract
The fasciculus gracilis and fasiculus cuneatus are both what
touch oriented
Where is the taste area of the brain found
the insula of the brain
Where does forethought and motivation occur
the prefrontal area
Left brained people are better at what
math and speech
Right brained people are better at what
artistic activities
A change in the neurons cytoskeletons shape is involved in what
long term memory
Are skeletal muscles controlled by the autonomic nervous system
no
In the sympathetic division of the ANS where is the cell body of the preganglionic neuron located
brain stem or lateral horn of the spinal cord
Which system has short postganglionic neurons near the effector organs
parasympathetic
Where is the enteric nervous system located
digestive system
Chain ganglia are part of what system
sympathetic
Which ramus communication is a short connection between a spinal nerve and a sympathetic chain chain ganglian thru which preganglionic neurons pass
white
There are 4 ways axons exit the sympathetic chain ganglia what are they
spinal, sympathetic, splanchnic nerves and innervation to the adrenal glands
Sympathetic stimulation of the adrenal medulla causes the release of what two hormones
epinephrine and norepinephrin
What is another name for parasympathetic ganglia
terminal ganglia
Nicotonic receptors are located where
cell bodies of both sympathetic and parasympathetic postganglionic neurons
Muscarinic receptors are located where
all parasympathetic and some sympathetic effectors
When acetylcholine binds with nicotonic receptors the response is what
excitatory
What do beta blockers do
reduces B/P
What are some examples of sympathetic effects on the body
increased coagulation
dilation of the pupils
relaxation of the ciliary muscle for far vision
decreased insulin secretion
Is there parasympathetic innervation of blood vessels
no
What does the hypothalmus do
integrates thoughts and emotions to produce ANS response
Sympathetic nervous system
fight or flight
Parasympathetic nervous syetm
rest and digest
WHich system would cause the dilation of the bronchial tubes in the lungs
SNS
