Answer:
Nerve plexuses are composed of afferent and efferent fibers that arise from the merging of the anterior rami of spinal nerves and blood vessels. There are five spinal nerve plexuses—except in the thoracic region—as well as other forms of autonomic plexuses, many of which are a part of the enteric nervous system. A plexus is a bundle of intersecting nerves, blood vessels, or lymphatic vessels in the human body. These bundles typically originate from the same anatomical area and serve specific areas of the body. Bundles of nerves that form a plexus communicate information to your brain about pain, temperature, and pressure.
Answer:
B) Messenger RNA
Explanation:
Messenger RNA [mRNA] molecules carry the coding sequences for protein synthesis and are called transcripts.Ribosomal RNA [rRNA] molecules form the core of a cell's ribosomes [the structures in which protein synthesis takes place] and transfer RNA [mRNA] molecules carry amino acids to the ribosomes during protein

When the body is too hot the nerves send signals to the muscles to lower the hairs on your body to cool yourself off by releasing the air
Mechanisms that regulate smooth muscle contraction (independently of nerves or hormones) by which organs and tissues alter their own arteriolar resistances and blood flow are referred to as : Myosin and actin
<h3>Meaning of Myosin and actin </h3>
Myosin and actin are proteins that are found in all type of muscle tissue.
Smooth muscles (Heart) do not need nerves but it is an involuntary action, due to the presence of the myosin and actin, it work continuously.
Myosin and Actin are like a sliding filament in the muscle structure of the heart. they cause the heart to work continuously.
in conclusion, the Mechanisms that regulate smooth muscle contraction (independently of nerves or hormones) by which organs and tissues alter their own arteriolar resistances and blood flow are referred to as : Myosin and actin
