Bones of the skeleton are connected at junctions called ________.
articulations
This is the most common type of skeletal cartilage.
hyaline
This type of cartilage supports the external ear and keeps it firm but flexible.
elastic
Vertebrae belong to this category of bones.
irregular

endosteum
What is the periosteum made of (tissue)?
Dense irregular connective tissue: covers outside of bone and protects it
articular cartilage is made up of what type of cartilage?
hyaline (covers ends of bones at joints to reduce friction)
Where would hematopoietic tissue be located?
In red bone marrow within the Spongy bone of ephiphyses
