I would put for them "nodes" and "joints".

However, I am not pretty sure about "nodes".

Fuge = joint.

I THINK this is correct, but I'm not a medical specialist.

Synarthroses are divided into three classes: fibrous, cartilaginous, and fibrocartilaginous; the last class is called symphysis.

synarthrosis A type of joint in which the skeletal elements are united by a continuous intervening substance (cartilage, fibrous tissue, or bone). Movement is absent or limited, and a joint cavity is lacking. It includes the synchondrosis, suture, and syndesmosis types of joints. SYN: synarthrodia.

suture
2 a : the line of union in an immovable articulation (as between the bones of the skull); also : such an articulation b : a furrow at the junction of adjacent bodily parts

Joints and Sutures
Now, we have our skeleton in formation, but how does it come together. It comes together in joints and sutures. It is important that we talk just a little about the various ways that joints meet. One way to break up the various types of joints is based on movement. A synovial joint or diarthrosis is a movable joint and a synarthrosis permits no relative movement between two articulated bones. Synovial joints have a synovial capsule made of dense, fibrous connective tissue filled with synovial fluid. After that is the articular cartilage. There are two types of synarthrosis, a synchondrosis and a syndesmosis. Synchondrosis is easy, it is where the two bones have cartilage at their aligned surfaces. A sysndesmosis is when the contact is with fibrous connective tissue. We call it a synostosis if the two bones fuse together and the bones are said to be ankylosed. If this is at the midline, we call it a symphysis such as the pubic or mandibular symphyses. Most sutures are syndesmoses.

SYNARTHROSIS: no movement allowed
a. Suture- (fibrous joint)
examples: sagittal suture, coronal suture, etc.
b. Synchondrosis- (cartilaginous joint)
examples: metaphysis of growing bone; 1st rib with the sternum
c. Gomphosis- (fibrous joint) example: teeth in sockets
