What are the four main features of the anatomical position?
- standing upright
- feet flat on floor
- arms at sides
- palms, face, and eyes facing forward
What are the 3 anatomical planes of section?
- Horizontal/Axial/Transverse
- Coronal/Frontal
- Sagittal
How does the transverse plane of section divide the body?
divides body into superior and inferior parts
How does the coronal plane of section divide the body?
anterior and posterior sections
How does the sagittal plane of section divide the body?
divides body into left and right sections

What are the main functions of the Integumentary System?
- protection of internal structures
- temperature regulation (homeostasis)
- somatosensation
- storage of water, fat, glucose, and vitamin D
What are the key structures of the Integumentary System?
skin, hair, and nails
What are the main functions of the skeletal system?
- biomechanical levers to facilitate movement
- protection of vital organs
- mineral storage
- hematopoeisis
What are the key structures of the skeletal system?
bones, cartilage, and joints/associated connective tissue
What are two defining features of synovial joints?
- articular cavity separates skeletal elements
- bones covered by hyaline cartilage
What is the defining feature of solid joints?
skeletal components held together by connective tissue and there is no articular cavity
What are the 3 types of fibrous joints?
sutures-linked by sutural ligament
gomphosis- linked by periodontal ligament
syndesmosis- linked by ligament
What are the 2 types of cartilaginous joints?
synchondrosis- ossification centers separated by cartilage
symphysis-separate bones linked by cartilage
