**Core Concept:** Ossification centers are sites where bone formation occurs, typically during development or healing. In humans, these centers are important for understanding bone growth and maturation.

**Why the Correct Answer is Right:** The correct answer is "C. Epiphyses," which refer to the ossification centers that appear at the ends of long bones during growth. This process primarily occurs in the diaphysis (midshaft) and epiphysis (ends) of long bones, allowing for elongation and growth.

**Why Each Wrong Option is Incorrect:**

A. **Salient:** Salient refers to something noticeable or important, not a specific ossification center.
B. **Appearing After Birth:** Ossification centers typically appear before birth, not after.
D. **Osteoid:** Osteoid is an immature bone matrix, not an ossification center.

**Clinical Pearl / High-Yield Fact:** Epiphyseal growth plates, also known as growth plates or physeal cartilage, are crucial for understanding pediatric bone growth and development. These plates transition into epiphyses after puberty, leading to the fusion of these plates and eventual bone maturation.
