Answer: d. none of the above
Explanation:
The respiratory membrane is the membrane which separates the air inside the alveoli from the pulmonary capillaries. The types of respiratory membranes includes the alveoli membrane, the capillary membrane and the basement membrane. The respiratory membrane is usually very thin. But it becomes thick due to the increase in the fluid content, which actually forces the gases to diffuse through the membrane and the fluid. Also the pulmonary diseases can also cause the membrane to become thick.

<h2>Cholinergic and Adrenergic neurons</h2>
Explanation:
The autonomic nervous system (ANS) is a dual innervations system which innervates internal organs of the body through the sympathetic and parasympathetic nervous system (PNS). Depending upon the neurotransmitter and receptor used, the ANS fibers are classified as cholinergic or adrenergic neurons.
The preganglionic neurons of the sympathetic and the preganglionic and postganglionic neurons of the parasympathetic nervous system release the neurotransmitter acetylcholine (ACH) and hence are called cholinergic neurons.
The postganglionic neurons of the sympathetic nervous system releases catecholamine like norepinephrine(NE) and hence called as adrenergic neurons.
The cholinergic neurons store ACH in the synaptic terminals. They are myelinated to aid in faster neurotransmission. The ACH neurotransmitter released from preganglionic neurons activates the two receptors – nicotinic ACH and muscarinic receptors on the postganglionic neurons
.
The postganglionic neurons releasing NE binds to the adrenergic receptors – Alpha 1 and 2, Beta 1, 2, and 3.
