- The phrenic nerve is derived from the cervical plexus and receives innervation from the C3, C4, and C5 nerve roots. It is the longest branch of the cervical plexus.
Why does phrenic nerve supply diaphragm?
- The C3-C5 spinal nerves in the neck give rise to the phrenic nerve, a mixed motor and sensory nerve.
- The diaphragm, the main muscle of respiration, is exclusively controlled by the nerve, making it essential for breathing.
What organ does this nerve supply?.
- The jejunum receives both intrinsic and extrinsic nerve supply.
- The preganglionic parasympathetic and postganglionic sympathetic branches of the celiac plexus provide the autonomic extrinsic supply.
- These neurons go via branches of the major vessels from the mesentery into the jejunum.
What are the 4 types of nerves?
It is conventional, however, to describe nerve types on the basis of their function: motor, sensory, autonomic or cranial.
- Motor Nerves.
- Sensory Nerves.
- Autonomic Nerves.
- Cranial Nerves.

Answer:
14.8% of H2O2
Explanation:
Based on the redox reaction of H2O2/MnO4- is:
2MnO4- + 5H2O2 + 6H+ ⇄ 2Mn2+ + 5O2 + 8H2O
<em>2 moles of KMnO4 react with 5 moles of H2O2</em>
<em />
To solve this question we need to find the moles of KMnO4 until reach the endpoint. Using the balanced reaction, we can find the moles of H2O2 that must be converted to grams using its molar mass -Molar mass H2O2: 34.015g/mol-:
<em>Moles KMnO4:</em>
0.0297L * (1.4686eq/L) = 0.04362eq MnO4- * (1mol / 5eq) = 0.008723 moles MnO4-
<em>Moles H2O2:</em>
0.008723 moles MnO4- * (5mol H2O2 / 2mol MnO4-) = 0.02181 moles H2O2
<em>Mass H2O2:</em>
0.02181 moles H2O2 * (34.015g/mol) = 0.7418g H2O2
<em>%:</em>
0.7418g H2O2 / 5.0mL * 100
<h3>14.8% of H2O2</h3>
<h3> Number = 23</h3>
<h2>Step-by-step explanation:</h2>
<h3>Given:</h3>
Six is subtracted from a number.
The result is equal to one fourth of the sum of the number and 45 find the number .
<h3 /><h3>To Find:</h3>
What is the number ?
Solution: Let the number be x.
➟ Subtracting 6 from x.
➟ (x – 6) ㅤㅤㅤㅤㅤ(eqⁿ 1)
Now,
➙ One fourth of sum of the number + 45
➙ 1/4 × x + 45
➙ x + 45/4ㅤㅤㅤㅤ(eqⁿ 2)
According to the question,
Equation 1 = 2
⟹ (x – 6) = x + 45/4
⟹ 4(x – 6) = x + 45
⟹ 4x – 24 = x + 45
⟹ 4x – x = 45 + 24
⟹ 3x = 69
⟹ x = 69/3
⟹ x =23
Hence, the number is 23.
