- 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:
The chemical receptors of cells have been defined as molecular structures to which other molecules considered as chemical messengers (neurotransmitters, hormones and other neuroactive molecules) specifically bind.
Chemical receptors can be located on the plasma membrane into which they insert by crossing it. Membrane domains have been defined for them and also on both sides of the membrane. The one on the external side corresponds to the binding site for messengers that come from other cells, a situation that defines the so-called heteroreceptors. If messengers coming from the cell itself join that site, the so-called autoreceptors are defined.
But chemical receptors can also be located inside cells. They are intracellular receptors and are found in the cytoplasm or in the nucleus. Messages act on them, which due to their chemical nature can cross the plasma membrane, such as steroidal hormones, thyroid hormones and neurosteroids

Pregnancy has no effect on blood flow. receiving a blood transfusion increases blood flow greatly.
<h3>What is blood transfusion?</h3>
Intravenously putting blood components into a person's circulation is known as a blood transfusion. For a number of medical disorders, transfusions are performed to replenish lost blood components.
Patients who have sustained major injuries in vehicle accidents or natural disasters are treated with blood transfusions. Blood transfusions are frequently given to people who have a condition like leukemia or kidney disease, both of which can induce anemia.
Through a little tube inserted into a vein in your arm, donated blood is given to you as part of a standard medical operation known as a blood transfusion. Blood lost during surgery or an accident can be replaced with the aid of this potentially life-saving technique.
