Which muscle is described as pear-shaped?

Explanation:
Pear-shaped describes a muscle that has a broader base and tapers toward the end, giving a compact, tapered look. The piriformis fits this shape in the deep gluteal region: it starts on the anterior surface of the sacrum, passes laterally through the greater sciatic foramen, and attaches to the superior border of the greater trochanter. This results in a relatively small, tapered muscle that resembles a pear. The other gluteal muscles have different shapes—gluteus medius is broad and fan-like, gluteus maximus is large and bulky, and tensor fasciae latae is slender with a long tendon—so they don’t match the pear-shaped description as well.
