• part 3 — types of bones

complete the table using the word bank.

Explanation:

Part 3 – Types of Bones

1. Femur is a long bone; there are 80 long bones in the human skeleton.
2. Carpals are short bones; there are 54 short bones in the human skeleton.
3. Sternum is a flat bone; there are 126 flat bones in the human skeleton.
4. Vertebra are irregular bones; there are 26 irregular vertebrae (including sacrum and coccyx) in the human skeleton.
5. Patella is a sesamoid bone; there is 1 pair (2 total, but the word bank has 1, referring to each individual, standard for this type of worksheet) sesamoid patella per side, the given number 1 corresponds here.

Sort the Bones

1. Long bones are elongated with a shaft; Radius and Metacarpals fit this.
2. Short bones are cube-shaped; Tarsals fit this.
3. Flat bones are thin and broad; Scapula fits this.
4. Irregular bones have complex shapes; Mandible fits this.

Part 4 – Synovial Joints

Hinge joints allow only flexion and extension (unidirectional bending), which corresponds to no specific letter given, but the function matches reducing friction at joints (A) is a general joint function, but hinge joint's movement is flexion/extension, the only relevant function tied to joint structure is A, as synovial joints (including hinge) have cartilage to reduce friction.
