Explanation:

• For Question 11: Rachi/o - and spondyl/o - are medical combining forms related to the spine, vertebral column, or vertebra. Radi/o - relates to the radius (bone in the forearm) and trachel/o - to the neck. Skelet/o - is about the skeleton in general and ile/o - to the ileum (part of the small intestine). Rect/o - is for the rectum and tars/o - for the tarsus (ankle bones).
• For Question 12: Myofilaments are the basic units that make up myofibrils. Endomysium is connective - tissue around individual muscle fibers. A muscle fiber bundle is a group of muscle fibers. Perimysium is connective - tissue around muscle fiber bundles.
• For Question 13: The term meniscus comes from Greek and means crescent - shaped. It is a crescent - shaped fibrocartilage in joints like the knee.
