<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.
Answer:
They make the protein fibers in CT
Explanation:
Fibroblast is a proteinous compound which aids the synthesis and maintenance of extra cellular matrix.
They also help in the wound healing processes of the body and as a major component of the connective tissues in the body also.
The analysis above then validates the fibroblast as making the protein fibers in the connective tissue.

-Ultraviolet (UV) exposure – The sun is the most well-known source of UV radiation, but UV rays also come from tanning beds and other artificial sources.
-Genetics – Some risk factors of skin cancer can be inherited through our DNA.
-Immunosuppression – Some conditions, like AIDS, and certain medications, such as those provided after organ transplants, can suppress the body’s immune system and might contribute to the development of skin cancer.
-Radiation exposure – In addition to UV, there are other forms of radiation that may adversely affect the skin cells, such as X-rays or therapeutic radiation.
-Toxic sunscreens -- Most sunscreens block the absorption of Vitamin D with toxic chemicals that seep through the skin and into the bloodstream and all throughout your body. Using these toxic sunscreens could actually cause cancer. Some toxic ingredients that are in these kinds of sunscreens: oxybenzone. benzene, parabens, homosalate, octinoxate, and octocrylene
Caucasians are more at risk for skin cancer because they have less melanin produced in their skin. Lighter skin tones produce less melanin and are more prone to damaged DNA particulate from UV radiation.
