The first attempts to make sewing machines failed, largely because the inventors tried to make machines that could mimic the motions of hand sewers. Early machines used a single strand of thread and needles with eyes on the blunt ends, which were pushed completely through the cloth.
The bicipital aponeurosis (also known as lacertus fibrosus) is a broad aponeurosis of the biceps brachii which is located in the cubital fossa of the elbow and separates superficial from deep structures in much of the fossa. The bicipital aponeurosis originates from the distal insertion of the biceps brachii.While the tendon of the biceps inserts on the radial tuberosity, the aponeurosis reinforces the cubital fossa, and helps to protect the brachial artery and the median nerve running underneath.This protection is important during venipuncture (taking blood) from the median cubital vein.ome individuals (about 3% of the population) have a superficial ulnar artery that runs superficially to the bicipital aponeurosis instead of underneath it. These individuals are at risk for accidental injury to the ulnar artery during venipuncture.
Occipital Nerve Block. An occipital nerve block is an injection that numbs the nerves at the back of the head. There are four nerves on each side of the scalp. Occipital nerves allow us to feel sensations in the scalp. An occipital nerve block is done to decrease headache pain, caused by migraine, injury (concussion), muscle tightness or occipital neuralgia. The medicine used is either a local anesthetic or a combination of a local anesthetic and a steroid. The medicine is placed around the occipital nerves, which are located just beneath the skin, in the back of the head. The occipital block is usually done in the office.
