Musculoskeletal OSCE Exam Questions

Question 1

Functions of the Skeleton

Answer 1

Support Protection Erethrocyte (create & store red blood cells) Rigidity Movement & Minerals Storage of Energy

Question 2

Bone compostion

Answer 2

1. Compact - tough layer, appears solid and dense to the eye
2. Cancellous - inside, appears spongy
3. Periosteum - vascual fibrous membrane around bones

Question 3

Types of bone

Answer 3

1. Long -are some of the longest bones in the body, such as the Femur, Humerus and Tibia but are also some of the smallest including the Metacarpals, Metatarsals and Phalanges
2. Short - Short bones are defined as being approximately as wide as they are long and have a primary function of providing support and stability with little movement. Examples of short bones are the Carpals and Tarsals
3. Flat - Flat bones are as they sound, strong, flat plates of bone with the main function of providing protection to the bodies vital organs and being a base for muscular attachment. The classic example of a flat bone is the Scapula (shoulder blade). The Sternum (breast bone), Cranium (skull), os coxae (hip bone) Pelvis and Ribs are also classified as flat bones
4. Iggegular - These are bones in the body which do not fall into any other category, due to their non-uniform shape. Good examples of these are the Vertebrae, Sacrum and Mandible (lower jaw). They primarily consist of cancellous bone, with a thin outer layer of compact bone.
5. Sesamoid - Sesamoid bones are usually short or irregular bones, imbedded in a tendon. The most obvious example of this is the Patella (knee cap) which sits within the Patella or Quadriceps tendon.
