I also don't like how the bone and the marrow is the same colour - I'm not claiming to be an expert, but I recently did a bone dissection and the bone is certainly more white than the marrow. I don't believe the epiphyseal plates are in the right spot, and to me the main diagram in the Epiphyseal plate article, which yours resembles, is misleading.
Bone marrow is a semi-solid tissue found within the spongy (also known as cancellous) portions of bones. [2] In birds and mammals, bone marrow is the primary site of new blood cell production (or haematopoiesis). [3] It is composed of hematopoietic cells, marrow adipose tissue, and supportive stromal cells.
It is composed of 270 bones at the time of birth, [2] but later decreases to 206: 80 bones in the axial skeleton and 126 bones in the appendicular skeleton. 172 of 206 bones are part of a pair and the remaining 34 are unpaired. [3] Many small accessory bones, such as sesamoid bones, are not included in this.
Leg bones are the bones found in the leg. These can include the following: Femur – The bone in the thigh. Patella – The knee cap; Tibia – The shin bone, the larger of the two leg bones located below the knee cap; Fibula – The smaller of the two leg bones located below the patella
Diameter of canaliculi in human bone is approximately 200 to 900 nm. [1] In bovine tibia diameter of canaliculi was found to vary from 155 to 844 nm (average 426 nm). [ 2 ] In mice humeri it varies from 80 to 710 nm (average 259 nm), while diameter of osteocytic processes varies from 50 to 410 nm (average 104 nm).
Diagram of a typical long bone showing both compact (cortical) and cancellous (spongy) bone. Osteons on cross-section of a bone. In osteology, the osteon or haversian system (/ h ə ˈ v ɜːr. ʒ ən /; named for Clopton Havers) is the fundamental functional unit of much compact bone.
Many of the arteries, veins, nerves, and muscles in the leg are named according to what bone they are near (e.g. tibialis anterior and the tibial nerve are near the tibia). So the artery that runs near the smaller leg bone had two names: the peroneal artery and the fibular artery.
