the cervical plexus is a network of nerves formed in the neck.
formation : ventral rami of C1- 4 nerves. except first cervical nerve, other nerves divide into ascending and descending branches. these nerves unite to form loops on the anterior surface of the scalenus medius and levator scapulae muscles. the plexus is covered by the prevertebral fascia. the plexus is superficially related to sternocleidomastoid and internal jugular vein.
branches: they are classified into superficial, deep and communicating branches.
superficial branchesthey are cutaneous branches.transverse cutaneous nerve of neck (C2,3)
lesser occipital nerve(C2)
greater auricular nerve(C2,3)
supraclavicular nerves(C3,4)
deep branchesanterior branches supply:phrenic nerve(C3,4,5)- diaphragm
rectus capitis lateralis (C1)
rectus capitis anterior(C1)
longus capitis(C1-4)
longus colli (C3-8)
inferior limb of ansa cervicalis(C2-3)
scalenus anterior (C4,5,6)
posterior branches supplysternocleidomastoidc2levator scapulae c3,4
trapezius- c 3,4
scalenus medius c3,4.
communicating branches:superior cervical sympathetic ganglion communicates with C1-4 nerves by grey rami communicantes
What else can I help you with?
The phrenic nerve is a member of which nerve plexus?
Cervical plexus....
The obturator and femoral nerves branch from this plexus?
cervical plexus
What spinal nerves form a plexus?
The cervical spinal nerves form the cervical plexus, the brachial spinal nerves form the brachial plexus, the lumbar and sacral spinal nerves form the lumbosacral plexus, and the sacral spinal nerves form the sacral plexus.
The major plexuses of the spinal cord?
The major plexuses of the spinal cord are the cervical plexus (C1-C5), brachial plexus (C5-T1), lumbar plexus (L1-L4), and sacral plexus (L4-S4). These plexuses are networks of nerves that supply motor and sensory function to various regions of the body.
What primary nerve that controls breathing is found in which nerve plexus?
The nerve that control the larynx during breathing is the Vagus Nerve.
Where is Cervical plexus in the sensory pathway?
lower back
What makes up a network of nerves?
Plexus
What is a nerve emerging from the cervical plexus involved in breathing?
The Phrenic Nerve
What major nerve serves the head neck and shoulder plexus?
The major nerve that serves the head, neck, and shoulder plexus is the spinal accessory nerve (CN XI). It originates in the brainstem and courses through the neck to innervate muscles involved in head turning and shoulder shrugging.
The Nerve plexus that supplies the diaphragm and thus causes respiratory damage is the plexus?
The phrenic nerve plexus supplies the diaphragm and controls its movement during respiration. Damage to this plexus can lead to impaired breathing and respiratory function.
Which spinal plexus gives rise to the phrenic nerve and what organ does this nerve supply?
The phrenic nerve arises from the cervical plexus (C3-C5) and supplies the diaphragm, which is the primary muscle involved in breathing.
What are the four nerve plexuses?
Cervical: C1 - C5Innervates muscles of neck and extend into thoracic cavity, where they control diaphragmatic muscles. Major nerve: Phrenic...which provides entire nerve supply to diaphragm.Brachial: C5-T1Innervates pectoral girdle and upper limbs. Major nerves: Radial nerve, median nerve, ulnar nerve.Lumbar: T12 - L4Innervates pelvic girdle and lower limbs. Major nerves: Genitofemoral nerve, lateral femoral cutaneous nerve, and femoral nerve.Sacral: L4-S5Innervates pelvic girdle and lower limbs. Major nerves: Sciatic nerve (which branches into tibial and fibular nerves) and pudendal nerve.
