No, the sciatic nerve is not located in the brachial plexus. The sciatic nerve is a large nerve that originates in the lower back and runs down the back of each leg, while the brachial plexus is a network of nerves in the shoulder region that innervates the upper limb.
The median nerve is a member of the brachial plexus. It is formed by contributions from the lateral and medial cords of the brachial plexus, primarily from spinal nerve roots C6, C7, C8, and T1.

Brachial plexus (C5-T1)
The radial nerve is derived from the posterior cord of the brachial plexus, which is formed by the fusion of the posterior divisions of the upper, middle, and lower trunks of the brachial plexus.
The brachial plexus.
The function of the brachial plexus is cutaneous and muscular innervation of the upper limb. It is a network of nerves running from the spine and neck into the arm.
The first thoracic nerve roots are in the brachial plexus. The nerves pass through the neck, the armpit area, and then into the arm.
The axillary nerve, which arises from the brachial plexus, is primarily responsible for innervating the deltoid muscle. It provides motor innervation to the deltoid muscle, controlling its function of shoulder abduction.
The pectoralis minor muscle is located near the brachial plexus in the human body. It lies underneath the muscle and can sometimes compress or put pressure on the brachial plexus, which is a network of nerves that control movement and sensation in the arm. This can lead to symptoms like pain, tingling, or weakness in the arm and hand.
The brachial plexus is a network of nerves that originate from the lower cervical and upper thoracic spinal cord. It controls the muscles of the shoulder, arm, and hand, and provides feeling to the upper limb. Damage to the brachial plexus can result in weakness or loss of function in the affected areas.
The Ulnar nerve is located in the joint of the elbow. It is the largest unprotected nerve in the human body, therefore injuries are very common. It is also commonly referred to as the "Funny Bone".
