Exam 7: The Peripheral Nervous System: Efferent Division

The sympathetic nervous system is always excitatory to the organs it innervates.

The autonomic nervous system is

Sympathetic fibers originate from ____________________ and ____________________ spinal nerves.

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 -Has short preganglionic fibers

Indicate which type of neuron is associated with the characteristic by writing the appropriate letter in the blank using the answer code below. a.afferent and efferent neurons and interneurons b.afferent and efferent neurons c.afferent neurons d.efferent neurons e.interneurons f.none of the neurons -Lie entirely within the central nervous system

Indicate the characteristics of the types of autonomic receptors using the following answer code: a.nicotinic receptors b.muscarinic receptors c.alpha receptors d.beta-1 receptors e.beta-2 receptors f.alpha-1 and beta-1 receptors g.muscarinic, alpha, beta-1, and beta-2 receptors -Bind with acetylcholine released from preganglionic fibers

The parasympathetic nervous system dominates in situations when a person is afraid.

Indicate which type of neuron is associated with the characteristic by writing the appropriate letter in the blank using the answer code below. a.afferent and efferent neurons and interneurons b.afferent and efferent neurons c.afferent neurons d.efferent neurons e.interneurons f.none of the neurons -Release neurotransmitter that binds to peripheral, cholinergic receptors

Muscarinic receptors are found on the effector cells innervated by the parasympathetic division.

In the autonomic nervous system, a(n) ____________________ neuron sends impulses away from a ganglion.

Describe the events that occur at a skeletal neuromuscular junction.Include the following in your answer: action potential (on axon and muscle fiber), end-plate potential, terminal button, ACh, Ca⁺² channels, motor end plate, depolarization, and Na⁺ channels.

The two divisions of the efferent division of the peripheral nervous system are the ____________________ nervous system, which supplies cardiac muscle, smooth muscle, and glands, and the ____________________ nervous system, which supplies skeletal muscle.

Indicate which type of neuron is associated with the characteristic by writing the appropriate letter in the blank using the answer code below. a.afferent and efferent neurons and interneurons b.afferent and efferent neurons c.afferent neurons d.efferent neurons e.interneurons f.none of the neurons -Are responsible for thoughts and other higher mental functions

Parasympathetic stimulation ____ heart rate and ____ the motility in the digestive tract.

Nicotinic and muscarinic receptors are the two kinds of adrenergic receptors.
