Endochondral ossification is responsible for development of most bones including long and short bones, [4] the bones of the axial (ribs and vertebrae) and the appendicular skeleton (e.g. upper and lower limbs), [5] the bones of the skull base (including the ethmoid and sphenoid bones) [6] and the medial end of the clavicle.

In mammalian anatomy, the cribriform plate (Latin for lit. sieve-shaped), horizontal lamina or lamina cribrosa is part of the ethmoid bone.It is received into the ethmoidal notch of the frontal bone and roofs in the nasal cavities.
Bone morphogenetic protein 1, also known as BMP1, is a protein which in humans is encoded by the BMP1 gene. [ 5 ] [ 6 ] There are seven isoforms of the protein created by alternate splicing . Function
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.
By 1500 BC, the peoples of the Indus Valley were creating gold earrings and necklaces, bead necklaces, and metallic bangles. [citation needed] Before 2100 BC, prior to the period when metals were widely used, the largest jewellery trade in the Indus Valley region was the bead trade. Beads in the Indus Valley were made using simple techniques.
The body's shape is determined by a strong skeleton made of bone and cartilage, surrounded by fat (adipose tissue), muscle, connective tissue, organs, and other structures. The spine at the back of the skeleton contains the flexible vertebral column , which surrounds the spinal cord , which is a collection of nerve fibres connecting the brain ...
The masterful creative mind behind the Muppets, “Labyrinth,” “The Dark Crystal” and so much more, Henson is the focus of this immersive, Emmy-winning documentary from director Ron Howard ...
Bone mineral (also called inorganic bone phase, bone salt, or bone apatite) is the inorganic component of bone tissue. It gives bones their compressive strength . Bone mineral is formed predominantly from carbonated hydroxyapatite [ 1 ] [ 2 ] with lower crystallinity.
