Answer:
The correct answer is: do not enter into a plexus and directly connect to the structures they supply.
Explanation:
<u>The </u><u>anterior rami</u><u> of the thoracic spinal nerves </u><u>from T1 to T11</u><u> give birth to the </u><u>intercostal nerves</u>, which are part of the somatic nervous system.
The intercostal nerves supply the thoracic pleura and abdominal peritoneum, and they vary from the anterior rami of the other spinal nerves in that they each take their own path without forming a plexus, <em>directly connecting to the structures they supply</em>.
The intercostal nerves are derived from the somatic nervous system, unlike the autonomic nervous system nerves that innervate the visceral pleura of the thoracic cavity. They can govern muscle contractions and give sensory information about the skin and parietal pleura as a result of this. This explains why damage to the thoracic cavity's interior wall can be felt as a severe discomfort in the damaged area. Damage to the visceral pleura causes a pain that is not localized.

<u>Some overall examples of biotic and abiotic factors are listed below.</u>
<u>Biotic factors: predators, competitors for food, competitors for space, parasitism, disease, animals, plants.</u>
<u>Abiotic factors: sunlight, wind, soil, atmosphere, water, temperature, humidity, UV radiation, salinity, pH levels.</u>
Answer:
Explanation:
The barnacles are only able to attach themselves to surfaces in the water. Since the surface is limited, barnacles are attaching themselves to the other barnacles, crowding the rock. The muscles were not able to grow or attach themselves off the surface of the rock. Same thing with the mussels that are growing on the rock. So not only barnacles are crowding the rock, but Mussels as well are crowding the rock.
