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.
the skull. Your 3 pound (1.4 kg) brain needs a home...your skull! Your brain is protected by several bones. There are eight bones that surround your brain: one frontal bone; two parietal bones, two temporal bones, one occipital bone, one sphenoid bone and one ethmoid bone. These eight bones make up the cranium.Another 14 bones in the face make up the entire skull.There are also three small bones in each ear. Also protecting your brain are three layers of tissue called the meninges. A few of the bones have been colored in the diagram below.here is a large opening, called the foramen magnum, located in the back of the occipital bone. This is where the medulla ends and projects out of the skull. Smaller holes in the skull, called foramina, allow nerves and blood vessels to enter and leave the cranium.
