**Core Concept**
The epiphysis is a growth plate in long bones that ends in a rounded or oval end, typically forming a separate bone that eventually fuses to the rest of the bone shaft. In the human body, there are different types of epiphyses, which can be classified based on their location, shape, and development.

**Why the Correct Answer is Right**
The epiphysis can be classified into several types, including:
- **Apical epiphysis**: The end of a long bone, such as the femur, that is rounded or oval in shape.
- **Basal epiphysis**: A small, rounded or oval end of a long bone that is located at the base of the bone.
- **Intracapsular epiphysis**: An epiphysis that is located within a joint capsule, such as the patella.
- **Intramuscular epiphysis**: An epiphysis that is located within a muscle, such as the greater trochanter of the femur.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is not a recognized type of epiphysis.
**Option B:** This option is not a recognized type of epiphysis.
**Option C:** This option is not a recognized type of epiphysis.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the epiphysis is a growth plate that fuses to the rest of the bone shaft, typically in late adolescence or early adulthood. This fusion is a critical aspect of bone development and can be affected by various factors, including genetics, nutrition, and injury.

**Correct Answer: D.**
