The 4 New Body Parts Recently Discovered

TL;DR

Recent discoveries in human anatomy include the interstitium, a network of fluid-filled spaces that act as shock absorbers and transport fluids; Dua's layer in the cornea, a tough collagen layer that improves corneal surgeries; trans-cortical capillaries in long bones, which play a role in bone turnover; and the brain lymphatic system, crucial for waste removal and potentially linked to neurological diseases like Alzheimer's.

Transcript

{♫Intro♫} We spend a ton of time and energy studying the human body. Globally, hundreds of billions of dollars a year go into health research. The vast majority of that research asks questions broadly within the realm of physiology, or how our body functions. But discoveries in anatomy — or the study of the body’s structure and form — still happen ... Read More

Questions & Answers

Q: What is the significance of the discovery of the interstitium?

The interstitium's fluid-filled spaces act as shock absorbers and transport fluids, contributing to our understanding of disease spread and the lymphatic system's role.

Q: How does Dua's layer improve corneal surgeries?

Dua's layer, being a tough collagen layer, allows surgeons to delicately separate tissues during corneal surgeries, resulting in improved surgical outcomes and fewer transplant rejections.

Q: What is the role of trans-cortical capillaries in long bones?

Trans-cortical capillaries transport stem cells between bone marrow and the periosteum, helping maintain bone strength, prevent fractures, and potentially opening avenues for fracture healing therapies.

Q: How does the brain lymphatic system impact neurological diseases?

The brain lymphatic system, involved in waste removal, is potentially linked to neurological diseases like Alzheimer's. Monitoring lymphatic activity in the brain could aid in early detection and treatment.

Summary & Key Takeaways

• The interstitium, discovered in 2015, is a network of fluid-filled compartments that act as shock absorbers and hold fluids en route to the lymphatic system.

• Dua's layer, identified in 2013, is a thin, collagen layer in the cornea that improves corneal surgeries and protects against tearing.

• Trans-cortical capillaries are extremely thin blood vessels found in long bones, facilitating the transportation of stem cells between bone marrow and the rest of the body.

• The brain lymphatic system, confirmed in 2015, plays a vital role in waste removal and has implications for understanding and treating neurological diseases.
