The outermost membranous layer covering the bone is the periosteum. Beneath it are, in order, blood vessels, compact bone, spongy bone, and bone marrow, where blood cells are produced.
The outer surface of the bone is called the periosteum.
No, bone marrow is found inside the bone.
That would be the periosteum.

Spongy bone looks something like a sloppily made honeycomb covered with an outer layer of solid compact bone. The spaces in the spongy bone are filled with red bone marrow and blood vessels.
The innermost part of the bone in called the Bone Marrow or inner bone
well bone marrow is a substance that is inside of the bone, so there for bone marrow is part of the skeletal system.

Bones are made of a soft matrix which is then calcified with calcium hydroxyapatite, which gives it a rigid structure. The outermost layer is called the periosteum, and is a tough, fibrous layer to which ligaments and tendons attach. The next layer is the cortical bone, which is very rigid and hard. It provides the shape and structure of the bone. The next layer in is the cancellous bone layer, which is a bit softer, and provides space for vascular elements and marrow. The cancellous bone makes the bones lighter. In humans, the cortical bone makes up about 80% of bone mass, while cancellous bone is about 20%.
