Question 1

MATCHING
Indicate which part of the autonomic nervous system is being described by writing the appropriate letter in the blank using the following answer code.
-Has a long preganglionic fiber and a short postganglionic fiber.
A)sympathetic nervous system
B)parasympathetic nervous system
C)both sympathetic and parasympathetic nervous system
D)somatic system

Accepted Answer

This is a characteristic of the parasympathetic nervous system, which has long preganglionic fibers that extend near or into the target organ and short postganglionic fibers.

Question 2

Match chemical with correct characteristic.
-Blocks release of ACh.
A)myasthenia gravis
B)black widow spider venom
C)curare
D)Clostridium botulinum toxin
E)organophosphates

Accepted Answer

Clostridium botulinum toxin, also known as botox, blocks the release of acetylcholine (ACh), a neurotransmitter involved in muscle contractions, ultimately leading to muscle paralysis.

Answer: C
 Curare also blocks the release of ACh, causing muscle paralysis. It is used as a muscle relaxant during surgeries.

Answer: E
 Organophosphates interfere with the breakdown of ACh, leading to an accumulation of the neurotransmitter and overstimulation of muscles, ultimately resulting in muscle paralysis.

Therefore, choices D, C and E are the best options as they all relate to the blocking of the release of ACh.

Question 3

Indicate the characteristics of the types of autonomic receptors using the following answer code (more than one answer may apply):
-Response to activation of this type of adrenergic receptor is generally inhibitory.
A)nicotinic receptors
B)muscarinic receptors

-Originates in the cranial and sacral regions of the CNS.
A)sympathetic nervous system
B)parasympathetic nervous system
C)both sympathetic and parasympathetic nervous system

Question 11

MATCHING
Indicate which part of the autonomic nervous system is being described by writing the appropriate letter in the blank using the following answer code.
-Originates in the thoracic and lumbar regions of the CNS.
A)sympathetic nervous system
B)parasympathetic nervous system
C)both sympathetic and parasympathetic nervous system
D)somatic system

Accepted Answer

The sympathetic nervous system originates in the thoracic and lumbar regions of the CNS, while the parasympathetic nervous system originates in the cranial and sacral regions. The somatic system is responsible for voluntary movements and is not part of the autonomic nervous system. C is not a correct answer as it does not accurately describe one specific part of the autonomic nervous system.

-Found in all autonomic ganglia.
A)nicotinic receptors
B)muscarinic receptors

The autonomic nervous system (ANS) is divided into two branches: the sympathetic and parasympathetic. Both branches innervate smooth muscle, cardiac muscle, and exocrine glands, so the correct answer is C. The somatic system, on the other hand, controls voluntary movements and skeletal muscle contraction.

-Predominates in relaxed situations.
A)sympathetic nervous system
B)parasympathetic nervous system
C)both sympathetic and parasympathetic nervous system

The parasympathetic nervous system is responsible for promoting rest and relaxation in the body, which is consistent with a "relaxed situation."

Question 20

Match chemical with correct characteristic.
-Causes explosive release of ACh.
A)myasthenia gravis
B)black widow spider venom
C)curare
D)Clostridium botulinum toxin
