1. Locomotor System Organization

Key Concepts & Definitions

  • Locomotor system : A coordinated set of bones, muscles, tendons, ligaments, cartilage, fascia, vessels, nerves, subcutaneous cellular tissue, and skin guided by signals from the nervous system.

Essential Points

  • The locomotor system provides support and protection, enables stability and movement during interaction with the environment, and forms a framework in which vital organs reside.

📌 The appendicular skeleton consists of two right and left thoracic limbs and two right and left pelvic limbs, whereas the axial skeleton consists of the head, laryngeal skeleton, thoracic cage, and rachis.

Memory Hook

Axial skeleton forms the central framework, whereas appendicular skeleton forms the four limbs.
