A haversian canal is a central canal within the haversian system — a network of canals inside compact bone. Haversian canals occur in the center of compact bone and contain blood vessels, connective tissues, nerve fibers and lymphatic vessels. Osteons, or the structure that forms compact bone, surround these canals and are the outer component of the haversian system.

Haversian systems are units of structure within mature bone. The systems run parallel to the long axis of bones. Each cylindrical unit within compact bone is an entire haversian system. The system includes lamellae, osteocytes, lacunae, canaliculi and a haversian canal.

Lamellae are the thin layers that compile and eventually form bone. They contain collagen fibers that are arranged in a parallel array. Lamellae also contain a small amount of proteoglycans in addition to collagen. This matter becomes mineralized and miniature crystals form along the collagen fibers. This process and layered arrangement creates strength in the bone.

The shaft of a long bone is made of compact bone. Compact bone is made of osteons, which produce osteocytes. These osteocytes are mature bone cells and are responsible for maintaining the integrity of the bone. Osteocytes form in tiny chambers called lacunae.

The spinothalamic tract consists of two adjacent pathways: anterior and lateral. The anterior spinothalamic tract carries information about crude touch. The lateral spinothalamic tract conveys pain and temperature.
The pathway decussates at the level of the spinal cord. Whereas the posterior column-medial lemniscus pathway and lateral corticospinal (not spinaothalamic)tract cross in the brain stem as the internal arcuate fibers and become medial lemniscus.

The posterior column, made up of the gracile fasciculus and the cuneate fasciculus is part of an ascending pathway carrying well-localized fine touch and proprioception (joint position sense and pressure sense)Lesions in this pathway can diminish or completely abolish movement or position sense below the lesion.
There are two types of cells that work together to alter the bones in response to many environmental factors: osteoblasts and osteoclasts. Bone is a hardened matrix composed mainly of the mineral calcium phosphate and the protein collagen. This matrix is produced and secreted by osteoblasts. Osteoblasts make bone in response to growth factors and mechanical stress on the bone.

Counteracting the osteoblast activity are osteoclasts - the bone reabsorbing cells. Osteoclasts make and secrete digestive enzymes that break up or dissolve the bone tissue. Osteoclasts then take up or 'absorb' the bone debris and further break it down inside the cell. The collagen is broken down into amino acids, which are recycled to build other proteins, while the calcium and phosphate are released to be used elsewhere in the body.
Sphenoid Bone
A hinge joint is a bone joint in which the articular surfaces are molded to each other in such a manner as to permit motion only in one plane.  Uniaxial. The direction which the distal bone takes in this motion is seldom in the same plane as that of the axis of the proximal bone; there is usually a certain amount of deviation from the straight line during flexion. The articular surfaces of the bones are connected by strong collateral ligaments.
Examples : the Interphalangeal joints of the hand and those of the foot and the joint between the humerus and ulna. The knee joints and ankle joints are less typical, as they allow a slight degree of rotation or of side-to-side movement in certain positions of the limb. The knee is the largest hinge joint in the human body. They are synovial joint.
Other objects that work like hinged joints are door hinges, closet doors, and dog flaps.
