The
receptors found in the retina are:
|
photoreceptors
|
|
Which
type of receptor provides continuous information about the stimuli
being monitored?
|
Tonic
receptor
|
|
The
parasympathetic nervous system:
|
A) has
long preganglionic fibers that end on terminal ganglia, which lie in
or near the effector organ
b) dominates in quiet, relaxed situations c) have fibers that originate from the cranial and sacral portions of the CNS |
|
Does not release acetylcholine
|
Sympathetic post-ganglionic fibers
|
|
Acetylcholine
|
A)
is released from the vesicles when an action potential is propagated
to the terminal button of a motor neuron.
b) increases the permeability of the motor end plate to Na+ and K+ when combined with the receptor sites on the motor end plate. c) is the chemical transmitter substance at the neuromuscular junction. |

|
Releases acetylcholine
|
A. sympathetic pre-ganglionic fibers
b. parasympathetic pre-ganglionic fibers c. motor neurons d. parasympathetic post-ganglionic fibers |
|
T / F
Adrenergic receptors are both excitatory and inhibitor, depending on subtype |
True
|
|
The sympathetic nervous system
|
A. has short pre-ganglionic fibers that end in ganglia, that are located close to the CNS
b. dominates in stressful situations c. have fibers that originate from the lumbar and thoracic portions of the CNS |
|
Which component of the reflex arc directly sends an impulse to an organ making a response?
|
Efferent pathway
|
|
The normal sequence of structures activated for signal transmission and response in the body is
|
Receptor - afferent neuron - interneuron - efferent neuron - effector
