feralis notes question of joint types

[glme]

Members don't see this ad.

in feralis notes, it says

joint types:
1. fibrous: connects bones without allowing any movement. ex: skull, pelvis, spinous process and vertebrae
2. cartilaginous: bones attached by cartilage, allow little movement ex) spine and ribs

as for the difference between the spinous process, vertebrae, and the spine, are the first two what composes the spine? spinous process and vertebrae is what makes up the spine? so the individual units cannot move but the long rod can move?


thank you for your help in advance.

Pretty sure that 'spine' is particularly referring to the intervertebral disc, which is a cartilaginous joint. Spinous process is a protuding part of the individual vertebrae units, where other vertebral units can attach. This is a fibrous joint. Hope this helps.

The way I wrote this was kind of messy because I wrote down areas of the body that have multiple joint types, so as it stands it's pretty unclear (for example, the pelvis has fibrous joints at the pelvic symphysis, not all pelvic joints are fibrous). Vertebral bodies themselves are separated by cartilaginous joints (the intervertebral discs are a part of these). The ribs are connected to the sternum via cartilaginous joints as well (the joint where the ribs and spine connect are synovial).

I think there is a fibrous joint involved with the spinous process but it's incredibly obscure and not needed for the DAT (not to mention conceptually confusing) - I would just disregard that.

I believe you're thinking of the articulating processes where joints can form - I don't think other vertebral units attach at the spinous process.
