Understanding the Suspensory Ligament
While 'suspensory ligament' refers to a type of fibrous tissue, it is not a single, specific structure. Instead, it is a classification for ligaments that support or suspend a body part, especially an organ. This general term is used in various contexts, from equine anatomy to human biology, but when discussing a specific ligament, a more precise name is used. Understanding this distinction is key to comprehending medical and anatomical texts.
The Role of Suspensory Ligaments
At their core, suspensory ligaments serve a supportive function. They anchor organs and other structures to the surrounding skeletal or fascial framework, ensuring that the body parts remain in their proper position. Without this support, gravity and movement could cause organs to shift, potentially leading to medical issues. The integrity of these ligaments is vital for the proper function of the associated organ.
Specific Names by Anatomical Region
Answering the question, "What are suspensory ligaments also called?" requires looking at the specific part of the body. Here are some of the most notable examples and their alternative names:
Suspensory Ligaments of the Breast (Cooper's Ligaments)
Named after Sir Astley Cooper, who first described them in 1840, these are the primary connective tissues within the breast. They run from the deep fascia over the pectoral muscles through the breast tissue and attach to the dermis of the skin. Cooper's ligaments are responsible for maintaining the shape and structural integrity of the breasts. When these ligaments lose elasticity or become stretched, it contributes to breast sagging over time.
Suspensory Ligament of the Eyeball (Lockwood's Ligament)
Forming a hammock-like structure, Lockwood's ligament is a supportive tissue that helps to hold the eyeball in position within the eye socket. It extends below the globe, stretching between the medial and lateral check ligaments. Damage or weakening of this ligament can lead to the downward displacement of the eye, a condition that can have significant effects on vision.
Suspensory Ligament of the Ovary (Infundibulopelvic Ligament)
This fold of peritoneum extends from the ovary to the wall of the pelvis, acting as a supportive structure. It is also referred to as the infundibulopelvic (IP) ligament. This ligament is particularly important because it contains the ovarian artery and vein, and therefore provides the neurovascular supply to the ovary. As such, it is a crucial landmark for surgeons during pelvic procedures.
Suspensory Ligament of the Lens (Zonule of Zinn)
In the eye, a series of fibrous strands connect the ciliary body to the lens, forming the suspensory ligament of the lens. These fibers, collectively known as the zonule of Zinn, play a crucial role in accommodation, the process by which the eye focuses on objects at varying distances. By altering the tension on the lens, the ciliary muscle is able to change its shape.
Suspensory Ligament of the Penis
This ligament attaches the top of the penis to the pubic symphysis, helping to support it. While it doesn't have a common alternative name, it is a key structure in male anatomy.
Comparison of Suspensory Ligaments
To illustrate the diversity of structures referred to by this general term, the table below provides a quick comparison of some of the most prominent examples.
| Ligament Name | Also Called | Location | Primary Function |
|---|---|---|---|
| Suspensory ligaments of the breast | Cooper's ligaments | Breast | Maintain breast shape and support |
| Suspensory ligament of the eyeball | Lockwood's ligament | Eye socket | Support the eyeball's position |
| Suspensory ligament of the ovary | Infundibulopelvic ligament | Pelvis | Provide neurovascular supply to the ovary |
| Suspensory ligament of the lens | Zonule of Zinn | Eye | Change lens shape for focusing (accommodation) |
| Suspensory ligament of the penis | Penis | Support and anchor the penis |
The Clinical Relevance of Suspensory Ligaments
Medical professionals frequently need to identify and reference specific suspensory ligaments, which is why the more precise names are so important. Injury or damage to these structures can have significant health implications. For example, stretching of Cooper's ligaments is a natural consequence of aging and gravity, but it can also be exacerbated by factors like large breast size, multiple pregnancies, and weight fluctuations. In the eye, a weakened Lockwood's ligament can contribute to a sunken eye appearance.
Understanding the correct terminology is also critical for surgical procedures. For instance, the infundibulopelvic ligament is a key surgical landmark during procedures involving the ovaries due to its vascular contents. Surgeons must be aware of its location and contents to avoid complications.

Conclusion
In summary, the term "suspensory ligament" is a broad anatomical descriptor. To get a precise answer to the question "What are suspensory ligaments also called?", one must specify the anatomical location. The alternative names are not mere synonyms but are a necessary part of precise medical and anatomical language, distinguishing between critical structures like Cooper's ligaments, Lockwood's ligament, and the infundibulopelvic ligament. This specificity is vital for both general understanding and professional medical communication.
