Combining Forms Of The Skeletal System: Chapter 6

The term "sacrum" refers to the triangular bone located at the base of the spine, formed by the fusion of five vertebrae. It plays a crucial role in connecting the spine to the pelvis and providing stability and support to the upper body. The given term "sacr/o" is a combining form that specifically relates to the sacrum. Therefore, the correct answer is "sacrum."

The term "humer/o" refers to the humerus, which is the bone located in the upper arm. This bone is commonly referred to as the humerus in medical terminology. Therefore, the correct answer is "humerus."

The correct answer is "ilium". The ilium is a bone that is part of the pelvis. It is the largest and uppermost bone of the pelvis, and it forms the prominence of the hip. The other options mentioned, such as tendon, kneecap, and curvature, do not relate to the given term "ili/o". Therefore, the ilium is the most appropriate answer in this context.

The term "ischium" refers to a bone in the hip. It is one of the three bones that make up the hip bone, along with the ilium and pubis. The ischium is located at the lower and posterior part of the hip bone. Therefore, the correct answer is "ischium, hip".

The given answer, "sternum, breastbone," is correct because the sternum is commonly referred to as the breastbone. The sternum is a flat bone located in the center of the chest, connecting the ribs and forming the front of the rib cage. It serves to protect the vital organs in the chest, such as the heart and lungs. Therefore, the sternum and breastbone are interchangeable terms referring to the same anatomical structure.

The term "tendon/o" refers to the combining form for tendon. Tendons are tough, fibrous cords that connect muscles to bones. They are responsible for transmitting the force generated by muscles to the bones, allowing for movement. The suffix "-o" is commonly used in medical terminology to denote a combining form. Therefore, "tendon/o" can be understood as the combining form for tendon.

The term "tibia" refers to the bone located in the lower leg, commonly known as the shinbone. It is one of the two long bones in the lower leg, with the other being the fibula. The tibia plays a crucial role in supporting body weight and providing stability during movement. It is also an important site for muscle attachment, as tendons connect muscles to the tibia. Therefore, among the given options, "tibia" is the most appropriate term related to bone and tendon.

The term "vertebr/o" refers to the vertebra, which is a bone in the spinal column. This term is derived from the Latin word "vertebra" meaning joint or joint of the spine. Therefore, the correct answer is "vertebra," as it is directly related to the term "vertebr/o."

The correct answer is "fibula". The term "fibula" refers to a bone located in the lower leg, on the lateral side. It is one of the two bones in the lower leg, along with the tibia. The fibula is slender and does not bear as much weight as the tibia, but it plays a crucial role in providing stability and support to the leg.

The term "oste/o" is a combining form that is derived from the Greek word "osteon" meaning bone. It is commonly used in medical terminology to refer to anything related to bones. Therefore, the correct answer for this question is "bone".

The term "lamin/o" refers to the thin plate-like structure. The sacrum is a bone located at the base of the spine, which does not match the definition of a thin plate. Similarly, the spine refers to the series of bones in the back, and the kneecap is a bone located in the knee joint. Therefore, the correct answer is lamina, as it accurately represents a thin plate-like structure.

The term "clavicul/o" refers to the collarbone or clavicle. The clavicle is a long bone that connects the shoulder to the sternum (breastbone). It is located in the upper part of the chest and plays a crucial role in stabilizing the shoulder joint and supporting arm movement. Therefore, "collarbone or clavicle" is the correct answer as it accurately represents the meaning of "clavicul/o."

The term "femor/o" refers to the femur, which is the thigh bone in the human body. The femur is the longest and strongest bone in the body, located between the hip and the knee. It plays a crucial role in supporting the weight of the body and facilitating movement. Therefore, the correct answer is "femur."

The term "carcin/o" is derived from the Greek word "karkinos," which means crab. It is used as a combining form to refer to cancer. Cancer is a disease characterized by the uncontrolled growth and spread of abnormal cells in the body. The term "carcin/o" is commonly used in medical terminology to indicate cancer or cancer-related conditions. Therefore, the correct answer for this question is "cancer."

The term "crani/o" refers to the skull. It is derived from the Greek word "kranion," which means skull. Therefore, "crani/o" is the correct answer because it specifically relates to the skull, not the toe or kneecap.

The term "arthr/o" refers to the joint, and "tibia" refers to the shinbone. Therefore, the combination of "arthr/o" and "tibia" suggests a joint related to the shinbone. The other options, wrist and glue, do not relate to the given terms. Hence, the correct answer is joint.

The word "spin/o" is a medical term that refers to the spine. Therefore, the correct answer is "spine" as it is directly related to the given term.

The term "burs/o" refers to a pouch-like structure in the body. This can be seen in various anatomical terms such as bursa, which is a small fluid-filled sac that cushions and reduces friction between tissues such as bones, tendons, and muscles. Therefore, the correct answer for this question is "a pouch".

The correct answer is "coccyx, tailbone". The term "coccyg/o" or "coccyg/e" refers to the coccyx, which is the small triangular bone at the base of the spine. It is commonly known as the tailbone. The other options mentioned, such as collarbone and humerus, are unrelated to the term "coccyg/o" or "coccyg/e".

The word "carp/o" refers to the bones of the wrist, so the correct answer is "wrist". The other options, spine, elbow, and hand, do not correspond to the term "carp/o".

The term "sarc/o" refers to flesh or connective tissue. This is the correct answer because it matches the meaning of the prefix "sarc/o" which is commonly used in medical terminology to indicate flesh or muscle. The other options, such as bone, wrist, and joint, do not match the meaning of "sarc/o" and are therefore incorrect.

The correct answer is coccyx, tailbone. The term "coccyx" refers to the small triangular bone at the base of the spine, commonly known as the tailbone. The term "tailbone" is a more colloquial term for the same bone. Therefore, both "coccyx" and "tailbone" are correct terms to describe the bone located at the end of the vertebral column.

The term "mandibul/o" refers to the lower jawbone. This can be inferred from the word "mandible," which is the anatomical term for the lower jawbone. The other options, such as "upper jawbone," "bone marrow," and "radius," do not correspond to the term "mandibul/o." Therefore, the correct answer is "lower jawbone."

The term "uln/o" refers to the ulna bone, which is one of the two bones in the forearm. The clavicle is the collarbone, the wrist is the joint connecting the hand to the forearm, and the neck is the part of the body connecting the head to the shoulders. Therefore, the correct answer is "elbow," as it is the joint connecting the upper and lower arm.

The word "menisc/i" refers to the meniscus, which is a crescent-shaped structure found in the knee joint. The other words in the list, such as small, rib, and glue, do not have any direct connection to the term "menisc/i". Therefore, the correct answer is "crescent" because it is the only word that is related to the shape of a meniscus.
