The study of the structure of the human body.

The study of the function of the human body.

The standard reference position for describing anatomical features.

A flat surface that divides the body or organ into sections.

A vertical plane that divides the body into right and left halves.

A horizontal plane that divides the body into superior and inferior portions.

A vertical plane that divides the body into anterior and posterior sections.

The outermost layer of the skin, composed of stratified squamous epithelium.

The skeletal system provides support, protection, movement, mineral storage, blood cell production, and energy storage.

The six shape classes of bones are long, short, flat, irregular, sesamoid, and sutural.

A long bone consists of a diaphysis (shaft), epiphyses (ends), articular cartilage, periosteum, medullary cavity, endosteum, and bone marrow.

The periosteum is a tough, fibrous membrane that covers the outer surface of a bone, while the endosteum is a thinner membrane that lines the medullary cavity.

Osseous tissue is organized into cells (osteoblasts, osteocytes, osteoclasts), lamellae, osteons, lacunae, and canaliculi.

Intramembranous ossification forms bones directly from mesenchyme, while endochondral ossification uses a hyaline cartilage model.

Bone growth occurs through appositional growth (adding new bone tissue to the surface) and interstitial growth (growth from within the bone tissue).

Bone fractures can be classified as closed, open, complete, incomplete, displaced, or nondisplaced. Aging leads to decreased bone density and increased risk of fractures.
