3. C
1. Correct!
2. Ahh, synarthroses are the least movable general type of joint. Plane (gliding) joints are synovial joint with the least range of movement.
3. Yep!

1. Nail sinus/nail root?
2. C, flat bone
3. Chondrocytes?
1. Close, I was looking for the nail matrix. The root is like the fold in the epidermis near the bone of the finger, where the nail body grows out from. However, the matrix is where the cells are produced to become the nail plate.
2. Correct!
3. Not quite, the answer is chondroblasts, chondrocytes are basically the mature cartilage cells.
Your turn!

all good, except 3 is Perimysium (the endomysium surrounds an individual muscle fiber, while the perimysium groups a bunch of them together)

Your turn!
