What is the cervical and brachial plexus?
The brachial plexus is a bundle of nerves that stems from nerve roots in the cervical (neck) and upper trunk (torso) sections of the spinal cord (C5-T1), creating a network that connects to the nerves in the arm.
Is cervical plexus same as brachial plexus?
The cervical plexus is formed from the C1–C4 spinal roots and is located in the lateral neck. It is the smallest of the plexuses. In comparison to the brachial plexus, iatrogenic neuropathies of the cervical plexus are rare or unrecognized.
What is a cervical plexus function?
The function of the cervical plexus is to provide skeletal muscle control of the neck and upper torso as well as providing cutaneous sensation to parts of the occiput, neck, and shoulder. The greater occipital nerve originates from the second cervical nerve independent of the cervical plexus.
What is cervical plexus in anatomy?
The cervical plexus is a group of nerves located in the neck. It is one of the most complex structures in the body, providing sensory and motor nerve supply to parts of the neck, upper back, and arms. Branches from the cervical plexus also supply nerve impulses to the diaphragm, a large muscle that powers breathing.
What does the brachial plexus innervate?
The brachial plexus is a major network of nerves transmitting signals responsible for motor and sensory innervation of the upper extremities, including the shoulder, arm, and hand.
What is a cervical plexus block?
Cervical plexus blocks (CPBs) have been used in various head and neck surgeries to provide adequate anesthesia and/or analgesia; however, the block is performed in a narrow space in the region of the neck that contains many sensitive structures, multiple fascial layers, and complicated innervation.
Where does the brachial plexus originate from?
The brachial plexus passes from the neck to the axilla and supplies the upper limb. It is formed from the ventral rami of the 5th to 8th cervical nerves and the ascending part of the ventral ramus of the 1st thoracic nerve.
Why is brachial plexus formed?
The brachial plexus is formed by the anterior primary rami of C5 through T1 and provides sensory and motor innervation of the upper extremity. The trunks can be found within the posterior triangle of the neck, between the anterior and middle scalene muscles.
What is the neck region called?
cervical spine
The neck, also called the cervical spine, is a well-engineered structure of bones, nerves, muscles, ligaments, and tendons.
Is brachial anterior or posterior?
The brachial plexus is formed by the anterior primary rami of C5 through T1 and provides sensory and motor innervation of the upper extremity. The brachial plexus is divided, proximally to distally into rami/roots, trunks, divisions, cords, and terminal branches.
How do you do the brachial plexus block?
Insert a block needle in-plane from posterior to anterior and lateral to medial, aiming for the deep portion of the brachial plexus where it overlies the first rib. Confirm negative aspiration, then inject a small amount of local anesthetic to raise the plexus off of the first rib.
What is the function of the cervical plexus?
Cervical plexus – serves the head,neck and shoulders.
What is the major nerve of the cervical plexus?
The ansa cervicalis which gives motor innervation branches to the infrahyoid muscles.
What are the 4 major nerve plexuses?
What are the 4 major nerve plexuses? Nerve plexus. Cervical plexus – serves the head, neck and shoulders. Brachial plexus – serves the chest, shoulders, arms and hands. Lumbar plexus – serves the back, abdomen, groin, thighs, knees, and calves. Sacral plexus – serves the pelvis, buttocks, genitals, thighs, calves, and feet.
Where is the cervical plexus located?
Lesser occipital nerve – innervates the skin and the scalp posterosuperior to the auricle (C2)
