Question

1: The parasympathetic nervous system will cause

a) your eyes to be dry

b) your eyes to water

2: The sympathetic nervous system will have ______________ preganglionic neurons.

a) long

b) either short or long

c) short

3: What type of receptor is on the effector in the sympathetic nervous system?

a) muscarinic receptors

b) alpha/beta receptors

c) nicotinic receptors

4: What type of receptor is on the effector in the sympathetic nervous system?

a) muscarinic receptors

b) alpha/beta receptors

c) nicotinic receptors

Answer 1

1.Option B-Eyes to Water.

The parasympathetic branch of ANS (autonomic nervous system) controls  lacrimal glands .

Parasympathetic Stimulation----------Release of neurotransmitter acetylcholine ----- both the nicotinic &muscarinic receptors----Activation of the Receptors------- Stimulation of  lacrimal gland --- produce tears--Cause eyes to Water.

2.Option C-Short

Sympathetic preganglionic Neurons are shorter than parasympathetic preganglionic neurons because sympathetic ganglia are situated Close to the spinal cord & parasympathetic ganglia are Situated little away from the Spinal Cord.

3.Option B-Alpha/Beta

The types of sympathetic receptors (adrenergic receptors) are

1.Alpha

2.Beta 1

3.Beta 2

In Sympathetic Nervous System,Major Neurotransmitter released are-Epinephrine and norepinephrine that acts on Alhpa,Beta 1 & Beta 2 receptors.

In Parasympathetic nervous System Neurotransmitter released is Acetylcholin,and they acts on Cholinergic receptors-That is Nicotinic and Muscarinic receptors.
