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 cranium is the upper bony structure of the skull, including everything except for the mandible, or jawbone. The cranium protects the brain and head, and supports facial structures such as the eyes and ears, holding them in the proper place to receive sensory information most efficiently.Animals that have a skull are collectively known as craniates. The cranium is not a single bone, but many.he human cranium consists of 21 bones and is subdivided into the neurocranium or brain case, which surrounds and protects the brain, and the splanchnocranium, which supports the structures of the face.
