KAAP220 Lecture Notes - Lecture 14: Wormian Bones, Appendicular Skeleton, Sesamoid Bone
Document Summary
Bones of skull, thorax, and vertebral column. Bones of the limbs and girdles that attach them to the axial skeleton. Provide surface area for skeletal muscle attachment. Complex shapes with short, flat, notched, or ridged surfaces. Examples: vertebrae, bones of pelvis, facial bones. Small, flat, and somewhat shaped like a sesame seed. Develop inside tendons of knee, hands, and feet. Examples: bones of the wrist (carpals) and ankles (tarsals) Sites for blood vessels or nerves to lie alongside or penetrate bone. Expanded proximal end of a bone that forms part of a joint. Narrow connection between the head and diaphysis of a bone. Tuberosity - small, rough projection that takes up a broad area. Trochlea - smooth, grooved articular process shaped like a pulley. Line- low ridge, more delicate than a crest. Ramus - extension of a bone that makes an angle with the rest of a structure. Canal or meatus - large passageway through a bone.
