Answer: (B)

Verified step by step guidance

1. Step 1: Understand the term 'Olecranon bursitis' by breaking it down: 'Olecranon' refers to the bony prominence of the elbow, and 'bursitis' means inflammation of a bursa, which is a fluid-filled sac that reduces friction between tissues. Therefore, Olecranon bursitis is inflammation of the bursa located at the elbow, not the shoulder or the bone itself.
2. Step 2: Recognize that bursae are found near joints to cushion and reduce friction. The olecranon bursa specifically cushions the elbow joint, so inflammation here causes pain and swelling at the elbow.
3. Step 3: For 'Polydactylism,' analyze the prefix and root words: 'poly-' means many, and '-dactyl' relates to fingers or toes (digits). Thus, polydactylism is a condition characterized by having more than the usual number of fingers or toes.
4. Step 4: Differentiate polydactylism from other digit abnormalities such as syndactyly (webbed digits), macrodactyly (abnormally large digits), or absence of digits. Polydactylism specifically refers to extra digits, not webbing or size changes.
5. Step 5: Summarize the correct definitions: Olecranon bursitis is inflammation of the bursa of the elbow, and polydactylism is the condition of having too many fingers or toes.
