- 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:
No. 5% of ciprofloxacin oral suspension for this child exceeds the therapeutic range.
Explanation:
Single dose of ciprofloxacin suspension shall be 400 mg
the pediatric oral dose is 10-20 mg/kg and body weight of child is 55 lb.
1 kg is 2.2 lb= 55÷ 2.2 = 25 kg
minimum required dose for child is 25 × 10= 250 mg
maximum required dose for child is 25 × 20 = 500 mg
1 teaspoonful is 5000 mg.
500 mg ÷ 5000 mg = 0.1 tsp
Hence, the dose exceeds the therapeutic range.

Health insurers can never discriminate based on genetic information in this way.
In small children or infants, a foreign body obstruction of the airway should be suspected if there is a sudden onset of <u>respiratory distress</u>
Signs of FBAO include a sudden onset of respiratory distress with coughing, gagging, stridor, or wheezing.
<h3>What is Foreign body airway obstruction(FBAO)?</h3>
Foreign object airway obstruction: Partial or complete obstruction of the airway to the lungs by a foreign object (food, beads, toys, etc.). Shortness of breath episodes can occur suddenly with a cough. Restlessness is common in the early stages of airway obstruction. Symptoms of shortness of breath include difficult and ineffective breathing (apnea) until the patient stops breathing. Loss of consciousness occurs if the obstruction is not removed.
Severe or complete foreign-body airway obstruction can kill the victim in minutes if he doesn't get appropriate treatment. The primary technique to clear an obstruction in a conscious adult is administration of abdominal thrusts—the Heimlich maneuver.
