The primary nerves involved in breathing are the phrenic nerve and the intercostal nerves. The phrenic nerve controls the diaphragm, the main muscle involved in breathing, while the intercostal nerves control the muscles between the ribs that help with the mechanics of breathing.
What else can I help you with?
Major functions of the phrenic nerves?
The major function of the phrenic nerves is to innervate the diaphragm, which is the primary muscle responsible for respiration. These nerves play a crucial role in controlling the movement of the diaphragm during breathing by sending signals from the brain to the diaphragm muscle. Dysfunction of the phrenic nerves can lead to respiratory issues and difficulty breathing.
How many nerves in your lungs?
There are no nerves located within the lungs themselves. However, the lungs are innervated by the pulmonary plexus, which consists of autonomic nerves that regulate functions such as breathing, blood flow, and airway constriction.
What is the nerves that carry activating impulses to the muscles of inspiration?
The nerves that carry activating impulses to the muscles of inspiration are primarily the phrenic nerves. These nerves originate from the cervical spinal cord (C3-C5) and innervate the diaphragm, the primary muscle of respiration. Additionally, the intercostal nerves, which arise from the thoracic spinal nerves, stimulate the intercostal muscles that assist in expanding the thoracic cavity during inhalation. Together, these nerves coordinate the process of breathing.
What spinal nerves may be involved in the case where a woman injures her neck in a car accident and now has difficulty breathing?
It should be the nerve to diaphragm.
Nerves that leave the brain directly are called?
Cranial nerves
Major functions of the phrenic nerves?

Dysfunction of the phrenic nerves can lead to respiratory issues and difficulty breathing.
When injuring a neck in a car accident and now having difficulty breathing which spinal nerves may be involved?
In a car accident that injures the neck and leads to difficulty breathing, the spinal nerves involved are likely those in the cervical region, particularly C3 to C5. These nerves innervate the diaphragm through the phrenic nerve, which is essential for breathing. Injury to these areas can impair respiratory function, leading to breathing difficulties.

what consists the peripheral nervous system?
-cranial nerves: which are located on the brain and carry impulses to the head and neck -spinal nerves: which extend from the spine and provide information to areas of the body below the neck -autonomile nerves: which responsible for involuntary body functions such as breathing and digestion
What stimulates diaphragm?
The diaphragm is primarily stimulated to contract by the phrenic nerves, which originate from the spinal cord. The phrenic nerves send signals to the diaphragm to contract and initiate breathing. Additionally, chemical factors like excess CO2 levels in the blood can also stimulate the diaphragm to increase breathing rate.
What spinal nerve serves the diaphragm?
Phrenic nerves from brachial and cervical plexus.
The central nervous system consists of the?
The central nervous system consists of the brain and spinal cord. The nerves leading from the spinal cord make up the peripheral nervous system.
Which nerves prepare the body for emergencies and stress as part of the response?
Sympathetic nerves: prepare the body for emergencies and stress by increasing the breathing rate, heart rate, and blood flow to muscles. These nerves become aroused as part of the fight-or-flight response, which is the body's natural reaction to real or imaginary danger.
Describe how breathing is controlled?
Autonomic nerves from the medulla oblongata to the diaphragm and chest muscles to produce the cycles of the cpntraction that bring air to the lungs
What spinal nerves may be involved in the case where a woman injures her neck in a car accident and now has difficulty breathing?
It should be the nerve to diaphragm.
Why can you not hold your breath until you lose consciouness?
Once you loose you consciousness, the involuntary muscles will act and it will trigger the nerves to do the normal thing such as "breathing"
