Exam 7: The Peripheral Nervous System: Efferent Division

Indicate whether the following autonomic anatomical and physiological features pertain to a.the parasympathetic division b.the sympathetic division c.both parasympathetic and sympathetic divisions d.neither parasympathetic nor sympathetic divisions -Causes fat breakdown in adipose tissue

ACh always causes depolarization of skeletal muscles.

Depolarization of the motor end plate results from more ____________________ ions entering the cell than ____________________ ions leaving the cell.

Indicate whether the following autonomic anatomical and physiological features pertain to a.the parasympathetic division b.the sympathetic division c.both parasympathetic and sympathetic divisions d.neither parasympathetic nor sympathetic divisions -Causes pupil constriction

Match the chemical with correct characteristic. a.myasthenia gravis b.black widow spider venom c.curare d.Clostridium botulinum toxin e.organophosphates -Binds with ACH receptor sites.

Binding of ____________________ to muscarinic receptors may initiate EPSPs or IPSPs.

Which neuron releases a neurotransmitter that binds to B₂ receptors?

Indicate which part of the autonomic nervous system is being described by writing the appropriate letter in the blank using the following answer code. a.sympathetic nervous system b.parasympathetic nervous system c.both sympathetic and parasympathetic nervous system d.neither sympathetic nor parasympathetic nervous system -Preganglionic fiber secretes acetylcholine

The sympathetic nervous system

The neuromuscular junction

Neuron 2

Indicate whether the following autonomic anatomical and physiological features pertain to a.the parasympathetic division b.the sympathetic division c.both parasympathetic and sympathetic divisions d.neither parasympathetic nor sympathetic divisions -Some preganglionic fibers synapse with postganglionic fibers outside of ganglia

____________________ fibers of the autonomic nerve pathway are located partially in the central nervous system.

An EPP is similar to an EPSP, except that the magnitude of an EPSP is much larger.

The autonomic nervous system mainly controls smooth and cardiac muscles, but it can inhibit a few skeletal muscles.

What would occur if ACh was not removed from the nicotinic receptors on skeletal muscle cells?

Sympathetic preganglionic fibers originate in the thoracic and lumbar segments of the spinal cord.
