Fracture healing occurrs in several steps: haemorrhage: blood and surrounding cells fill the space created by the fracture. fibrous callus: chondrocytes colonize the fracture space, with neovascularization. bony callus: osteocytes colonize the fracture space and rearrange in woven bone remodelling: in long bones, woven bone is remodelled into lamellar bone ...

They would die. Let's imagine that we perfectly cut a person down the middle. That would mean cutting the spinal cord in half, probably damaging the tissue so much that the remaining half wouldn't work well. The liver would be gone. The intestines and bladder would just be open. The heart would have to be adjusted to the left. The surgery would probably ...

They are actually different. INTERVERTEBRAL FORAMINA is actually spaces between adjacent vertebrae which gives passage for spinal nerves to exit. Whereas, VERTEBRAL FORAMINA forms vertebral canal. Source: Organization of the Nervous System: An introduction for students in the Human Anatomy Course

This looks like a misinterpretation. Because collarbone is the only horizontal long bone of the human body [1], it is the first to fracture when falling on the shoulder. Its fracture can affect many structures: The muscles involved in clavicle fractures include the deltoid, trapezius, subclavius, sternocleidomastoid, sternohyoid and pectoralis major ...

The best way to ensure you're getting an accurate skull, near as I can tell, is striking the "model" part of your question, and go straight for a real skull. A cursory search revealed, for instance, Skulls Unlimited International, The Bone Room, and The Evolution Store although other providers probably exist as well. A regulatory board for model skulls ...

The existence of the G-spot remains highly debated among researchers.  Two recent publications (Hines 2001, Kilchevsky et al. 2012) review studies of the so-called G-spot and conclude the evidence is too inconsistent to claim its definite existence.  Foldes and Buisson (2009) argue that the G-spot is actually just a clitoris that is richly  innervated. This ...

I am not sure whether I grasped the gist of your question appropriately, but let me provide some clarifications. $\text{Nerve}$ is simply a collection of axons. Therefore, all the spinal nerves are just bundles of assorted nerve axons. Now, the origin of nerve is slightly ambiguous as far as its meaning is considered. It can mean the physical origin, ...
