foramen magnum (Latin: 'great hole') is a large opening in the occipital bone of the cranium. It is one of the several oval or circular apertures in the base of the skull (the foramina), through which the medulla oblongata (an extension of the spinal cord) enters and exits the skull vault.

The opposite end of the muscle is called the origin.

Percussion is a method of tapping on a surface to determine the underlying structure, and is used in clinical examinations to assess the condition of the thorax or abdomen. It is one of the four methods of clinical examination, together with inspection, palpation and auscultation. It is done with the middle finger of one hand tapping on the middle finger of the other hand using a wrist action. The non striking finger (known as the pleximeter) is placed firmly on the body over tissue.. When percussing boney areas such as the clavicle the spleximeter can be omitted and the bone is tapped directly such as when percussing an apical cavitary lung lesion typical of TB.^[1]
There are two types of percussion: direct, which uses only one or two fingers, and indirect, which uses the middle/flexor finger. There are four types of percussion sounds: resonant, hyper-resonant, stony dull or dull. A dull sound indicates the presence of a solid mass under the surface. A more resonant sound indicates hollow, air-containing structures. As well as producing different notes which can be heard they also produce different sensations in the pleximeter finger.

Synovial membrane (or synovium)^[1] is the soft tissue found between the articular capsule (joint capsule) and the joint cavity of synovial joints. ^[2]
The word "synovium" is related to the word "synovia" (synovial fluid), which is the clear, viscid, lubricating fluid secreted by synovial membranes. The word "synvovia" or "sinovia" was coined by Paracelsus,^[3] and may have been derived from the Greek word "syn" ("with") and the Latin word "ovum" ("egg") because the synovial fluid in joints that have a cavity between the bearing surfaces is similar to egg white.
