Are there osteocytes in spongy bone?
Spongy bone tissue does not contain osteons that constitute compact bone tissue. Instead, it consists of trabeculae, which are lamellae that are arranged as rods or plates. Blood vessels within this tissue deliver nutrients to osteocytes and remove waste.
What is the 206 bones?

What kind of bones are in the pectoral girdle?
The pectoral or shoulder girdle consists of the scapulae and clavicles. The shoulder girdle connects the bones of the upper limbs to the axial skeleton. These bones also provide attachment for muscles that move the shoulders and upper limbs.
