ends of long bone that is made of spongy (cancellous) bone and red marrow
the tubelike, hollow space of diaphysis of long bone
shaft of bone. location of primary ossification center.
thin membrane that lines medullary cavity
a dense fibrous membrane covering the surface of bones (except at their extremities) and serving as an attachment for tendons and muscles
thin hyaline cartilage layer that covers epiphyses of bones in synovial joints
(bone building cells) Functions: synthesize and secrete collagen fibers and other organic compounds needed to build the matrix of the bone. Once full surrounded by bone matrix, they became trapped inside and become osteocytes.
(bone cell) Mature non dividing osteoblasts that have become surrounded by the matrix. They are the main bone cells and maintain daily metabolism of bone.
(bone absorbing) Giant cells that erode bone material. Funtion: secrete enzymes and acids that break down bone matrix to release calcium into the blood
fills the medullary cavity in adults. cells are saturated with fat and cannot produce anymore blood cells
produces red blood cells
most common type of cartilage. articular surface of bone, costal cartilage in ribs, rings in trachea, and tip of nose
gives from to the external ear, epiglottis, and auditory tubes
very strong and rigid. it is in the pubic symphysis and invertebral disks.
layer of hyaline cartilage that remains between the diaphysis and epiphysis until bone is done growing. in x rays you can esimate the age of an individual based on if present or how wide
secreted by parathyroid glands when blood calcium is too high. it stimulates osteoclast activity
secreted by the thyroid gland when blood calcium is too low to inhibit osteoclast activity
a partial fracture of a bone (usually in children). bent on one side but broken in outer arc
moving the foot so that the sole faces away from the midsagittal plane
moving the foot so that the sole faces towars the midsagittal plane
moving a part posteriorly
moving a part anteriorly

elongated forehead, wide sacrum, more movable coccyx
small pelvic inlet, subpubic angle less than 90 degrees, more massive muscle attatchment sites
