The term 'fossa trochanterica' refers to a bony depression located on the posterior aspect of the femur bone. The correct spelling of this word can be explained using the International Phonetic Alphabet (IPA) transcription. 'Fossa' is pronounced as /ˈfɒsə/, where the 'o' is pronounced as a short vowel. 'Trochanterica' is pronounced as /ˌtrɒkəˈntrɪkə/, with stress on the second syllable. The 'ch' is pronounced as a hard 'k' sound, and the 'er' in 'erica' is pronounced as a short 'i' sound. The spelling of 'fossa trochanterica' is crucial for accurate communication in medical settings.
The fossa trochanterica is a term derived from the Latin words "fossa" meaning "a ditch" or "a trench" and "trochanterica" referring to "trochanter," which is a bony prominence found on the femur. In anatomy, the fossa trochanterica is a depression or hollowed-out area found on the posterior side of the proximal femur, specifically on the greater trochanter.
Located at the topmost part of the femur bone, the fossa trochanterica is an indentation that forms the inferior aspect of the greater trochanter. It serves as an attachment site for several muscles, including the piriformis, gemellus superior, gemellus inferior, and obturator internus muscles. These muscles belong to the deep gluteal muscles and are responsible for hip joint movement and stabilization.
The fossa trochanterica plays a crucial role in supporting the hip joint during movements such as walking, running, and other lower limb activities. It provides an anchoring point for the muscles that control and stabilize the hip, contributing to the overall functionality and range of motion of the lower limb.
It is important to note that the fossa trochanterica is a distinctive anatomical feature exclusive to humans and some other mammals. Its presence and function are critical in facilitating the complex movements of the hip joint, enabling efficient locomotion and weight-bearing activities.
Trochanteric f., digital f., a depression at the root of the neck of the femur beneath the curved tip of the great trochanter; it gives insertion to the tendon of the obturator externus.

The word "fossa trochanterica" is primarily used in the field of anatomy to refer to a specific anatomical feature. Its etymology can be broken down as follows:
1. Fossa: The term "fossa" originated from the Latin word "fossus", which means "ditch" or "trench". In anatomy, it is used to describe a depression or hollow area in a bone or organ.
2. Trochanterica: The word "trochanterica" is derived from the Greek term "trokhantēr", which means "runner" or "ball". In anatomy, a trochanter is a prominence found on the femur (thighbone) that serves as an attachment point for various muscles involved in hip movement.
