Skeletal System Continued
This is the second installment of the skeletal system in the review section for massage therapist that are working towards passing the national certification examination.
The fibrous membrane that lines the medullary caivity is the endosteum.
The two major types of connective tissue in the skeletal system are bone, and cartilage. The names of the outer layers of the hard bone are dense and compact while the name for the porous bone at the end of the bones is called spongy bone. The needle-like threads of spongy bone that surrounds a network of spaces is called the trabecule.
The intracellular substance of the tissue is called a matrix an example of this is the bone its calcified and blood it is liquid. Numerous structural units that are how the matrix of bone is organized. The ring of calcified matrix surrounding the Haversian canal is called the concentrix lamella. The pathway in the bone that contains the blood vessel is called the central canal.
Bone Cells are called osteocytes, they are found between the hard layers of the lamellae. The spaces between the layers are called lacunae, while nutrients pass from the blood vessel in the harvesian canal to the osteocytes through the canaliculi.
