What is brachial plexus?
The brachial plexus is a network of nerves that controls movement and sensation in the shoulder, arm, and hand. It is formed by the combination of nerves from the cervical spine and supplies motor and sensory innervation to the upper limb. Damage to the brachial plexus can result in weakness, numbness, or paralysis in the affected arm.
Which spinal nerves comprise the brachial plexus and the lumbosacral plexus?
The brachial plexus is formed by the spinal nerves C5-T1, while the lumbosacral plexus is formed by the spinal nerves L1-S4. These plexuses are networks of nerves that supply motor and sensory innervation to the upper and lower limbs, respectively.
What do you call the large bundle of nerve under your armpit?
It is a continuation of the Brachial 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.
Describe brachial plexus palsy associated with nerve compression?
Brachial plexus palsy from nerve compression involves damage to the network of nerves that control movement and sensation in the arm. This condition can result from trauma, tumors, or other factors causing pressure on the nerves. Symptoms may include weakness, numbness, and pain in the affected arm, and treatment may involve physical therapy, medications, or surgery depending on the severity.
The anterior root and the posterior root fuse to form?
Each spinal nerve attaches to spinal cord by a ventral (anterior) root and a dorsal (posterior) root.All spinal nerves are mixed nerves (both motor and sensory).
Why are spinal nerves mixed nerves?
Spinal nerves are said to be mixes because their posterior roots contain sensory axons and their anterior roots contain motor axons.
Is the deltoid muscle innervated by the axillary nerve from C5 and C6?
The deltoid is innervated by the axillary nerve which originates from the ventral rami of the C5 and C6 spinal nerves, via the superior trunk, posterior division of the superior trunk, and the posterior cord of the brachial plexus.
WHAT IS THE DIFFERENCE BETWEEN THE ANTERIOR and POSTERIOR ROOT OF THE SPINAL NERVES?
The cerebrospinal nervous system consists of the brain, spinal cord and the peripheral nerves given off by these to the outer parts of the body. 31 pairs of nerves emerge from the spinal cord. Each nerve has 2 roots - 1 anterior(at the front of the spine) and 1 posterior (at the back of the spine) carrying sensory nerves. Motor nerves carry impulses to the muscles, & have the responsibility for bodily movement. On the other hand, sensory nerves are responsible for carrying sensory impulses which provide the brain with information about sensation i.e. hot and cold.
Structure is located within the posterior triangle?
The structure most commonly found in the posterior triangle of the neck is the brachial plexus, a network of nerves that supplies the upper limb. Other structures that can be found in this triangle include the external jugular vein and the spinal accessory nerve.
Do wasp have central nerves?
Yes. Like all insects its anterior rather than posterior to the body ... and all bugs have tiny "brains" - but they work well for their size.

Brachial plexus....
What major nerves serve the posterior thigh?

Which nerves innervate the taste buds?
Brances of the Facial (VII), Glossopharyngeal (IX), and Vagus (X) cranial nerves carry information about taste
