In endochondral ossification, cartilage is replaced with bone, and in intramembranous ossification, mesenchyme in an embryo is transformed into bone.
In endochondral ossification, mesenchyme in an embryo is transformed into bone, and in intramembranous ossification, cartilage is replaced with bone.
Endochondral ossification produces flat bones of the skull and the clavicle in the fetus.
Intramembranous ossification produces the long bones.

The Dermis is composed of connective tissue, and is part of the skin.
The hypodermis is composed of connective tissue, and is not part of the skin.
Thick skin is found in the palms of hands and soles of feet, and has sweat glands, but not hair follicles nor sebaceous (oil) glands.
Thin skin is found in the palms of hands and soles of feet, and has sweat glands, but not hair follicles nor sebaceous (oil) glands.

Typical histology of resting hyaline cartilage
Breakdown of lacuna walls, leaving open channels; death of chondrocytes; bone deposition by osteoblasts, forminc trabeculae of spongy bone.
Chondrocytes multiplying and lining up in rows of small flattened lacuna walls
Temporary calcification of cartilage matrix between columns of lacunae
Cessation of mitosis; enlargement of chondrocytes and thinning of lacuna walls
Protective enclosure of the viscera.
Maintenance of electrolyte balance.
Maintenance of acid-base balance.
Regulation of body temperature.
