In solid state electronics, either pure silicon or germanium may be used as the intrinsic semiconductor which forms the starting point for fabrication. Each has four valence electrons, but germanium will at a given temperature have more free electrons and a higher conductivity.
Circumduction. In anatomy, circumduction means to move a limb in a circular manner. Circumduction is defined as the movement pattern which is a combination of flexion, extension, adduction and abduction.ircumduction (Noun). The circular (or, more precisely, conical) movement of a body part, such as a ball-and-socket joint or the eye. It consists of a combination of flexion, extension, adduction, and abduction.
Neck anatomy is a well-engineered structure of bones, nerves, muscles, ligaments and tendons. The cervical spine (neck) is delicateâhousing the spinal cord that sends messages from the brain to control all aspects of the bodyâwhile also remarkably strong and flexible, allowing movement in all directions. The neck is connected to the upper back through a series of seven vertebral segments. Watch: Cervical Spine Anatomy Video. The neck begins at the base of the skull and through a series of seven vertebral segments connects to the thoracic spine (the upper back).
