Study Notes
Muscular System
- Responsible for most visible body movements, such as walking, running, and lifting.
- Generate approximately 85% of the body's heat.
Skeletal System
- Primary functions include support, movement, protection, production of blood cells, storage of minerals, and endocrine regulation.
- The sternum, a major component of the skeleton, has three distinct parts: manubrium (superior), body (middle), and xiphoid process (inferior).
Bone Formation
- Process of bone formation is called ossification.
- Two main methods of ossification: intramembranous and endochondral.
Urinary System
- Bladder and urethra derive from the cloaca, a common opening for the digestive, urinary, and reproductive systems in embryos.
