Pelvic Floor: “This complex layer of muscles and connective tissue seals our pelvis from below, supporting important organs such as bladder and intestines and maintaining our stability as well as an upright posture.

A strong pelvic floor is not only important for women. It plays a crucial role for movement, body awareness, and health in all people.

On the preparation, you can see a half-female pelvis in the Sagittarius cut. It shows the structures of the small pelvis with its internal organs in their natural position and makes visible what would otherwise remain hidden.”

Q: What is the green area?

“The sphenoid bone is one of the strangest looking bones in the human body, recognizable by its unique bat or butterfly shape. It’s a structural keystone of the cranium, situated centrally at the base of the skull. It articulates with twelve different bones, bridging the neurocranium and facial skeleton while housing critical neurovascular pathways.

The sphenoid bone is widely considered the central hub of modern skull base neurosurgery because it serves as the direct anatomical gateway for endoscopic endonasal approaches to the pituitary gland and parasellar region.”

Skull Bone Marrow: “PET and MRI imaging found elevated levels of TSPO protein in skull bone marrow of people with chronic back pain and knee osteoarthritis compared to healthy individuals, suggesting a potential new target in understanding and treating chronic pain.”

Chronic Traumatic Encephalopathy: “A new study found that one in four former N.F.L. players who died over a recent six-year period — and likely many more — had the incurable, progressive brain disease known as C.T.E.”

Immune System Influence on Physiology: “A 2025 Science Review offers an overview of recent research that reveals the immune system not only defends the body but also actively shapes and supports various life-sustaining processes through dynamic, reciprocal interactions with other physiological systems.”

Brain Science: “The evolution of the human brain may owe as much to fruit and honey as to meat…”

The findings challenge one of the dominant ideas about our ancestors' diet.”

“In the face of a cornucopia of food options in the modern world, many commentators have sought to look backwards to human ancestors for diet directions. In recent decades, attention has focused on the increasing consumption of animal foods as a driver of human evolution. Considering the changing requirements of an enlarging brain and the demands of reproduction, Brand-Miller et al. modeled the distribution of macronutrient requirements across four million years of hominid evolution. They concluded that glucose—from fruit and honey early on and later from the pounding and cooking of starch—was essential for the evolution of the human brain.”

Concepts of Traversing & Exiting Nerve Roots:

“Understanding the difference between Traversing and Exiting nerve roots is fundamental for correctly interpreting lumbar disc herniations and predicting clinical symptoms. Let's break it down using this clear anatomical illustration from the lumbar spine.

The Exiting Nerve Root (The "Named" Root)
These are the nerve roots that exit the spinal canal through the neuroforamen (the bony opening) of their corresponding vertebral level. For example, the L4 nerve root exits at the L4 level.

See in image: Follow the yellow roots down. The one that branches off to pass through the L4 foramen is the L4 exiting root.

The Traversing Nerve Root (The "Descending" Root)
These are nerve roots that travel downward within the spinal canal, passing behind the intervertebral disc of the level above, to exit at a lower level.

See in image: The diagram clearly labels several roots as "Traversing". Notice how the L4 root, for instance, continues to run down past the L3-L4 disc space before it eventually exits at the L4 foramen.

Clinical Relevance: The Importance of Differentiation
This distinction is critical for orthopedic assessment and surgical planning. A typical posterolateral disc herniation at the L4-L5 level will compress the traversing L5 nerve root, not the L4 root, because the L4 root has already exited the canal higher up.

Example: An L4-L5 disc herniation classically causes L5 radiculopathy (leg pain, weakness), while a herniation at L5-S1 affects the traversing S1 nerve root.”

The Climber’s Finger 🧗

“Finger flexor tendon (FT) pulleys are delicate anatomical structures whose primary function is to anchor the tendon sheaths to the underlying bone. They maintain the tendons in close proximity to the phalanges, thereby stabilizing them during finger flexion. This arrangement allows for efficient force transmission, preserves an effective lever arm, and prevents bowstringing, ensuring a full range of motion.”

Vagus Nerve: “The spatial organization of fibers in the human vagus has implications for vagus neuromodulation therapies.”

“Study Purpose: With its large numbers of afferent (sensory) and efferent (motor) fibers, the vagus is the main conduit for bidirectional communication between the brain and visceral organs and participates in autonomic reflexes regulating cardiorespiratory, gastrointestinal, and neuroimmune functions. In the human vagus, nerve fibers are arranged in fascicles.”
