Document Summary

Explain the principal functions of the skeletal system. Discuss the different types of the bones based on their shape. Describe the structural organization of the skeletal system and list the bones of the axial and appendicular skeleton. Name the major openings on the floor on the cranial cavity. Attachment point to muscles and assists in locomotion. Sesamoid bones (embedded in the tendon of muscles - patella) Prevents the friction between the tendon of that muscle and the joint. Significantly increase the mechanical efficiency of the muscles. Structural organization of the skeletal system (more details in textbook) Superior orbital fissure (long opening for passage of cranial nerves) Optic canal (round opening also for passage of cranial nerves) Inferior orbital fissure (on the floor on the orbital cavity) Nasal conchae (curved boney shells - middle, inferior, superior [only seen in. Occipital bone (bone in the back of the skull)
