- 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?

Answer:
True
Explanation:
Pacemaker cells, unlike other neurons in the body, can depolarized themselves (and therefore can fire action potentials) without the need of an external innervation of the autonomic nervous system.
Each class of pacemaker cells has its own intrinsic rate.
For example, sinoatrial node rate is 60-100 bpm (the normal heart frequency).
The atrioventricular node is also part of the electrical conduction system of the heart. When the sinoatrial node fails, atrioventricular node takes the lead (40-60 bpm).
The Food and Nutrition Board recommends that Americans consume 45% to 65% of their total calories from carbohydrates.
