Study Notes
Bone Shapes
- Long Bones: Include humerus, radius, ulna, femur, tibia, and fibula; characterized by length exceeding width, primarily involved in movement.
- Short Bones: Examples are carpals and tarsals; these bones are approximately equal in length and width, providing support and stability with little movement.
- Flat Bones: Such as the clavicle, scapula, sternum, and ribs; these bones provide protection to internal organs and serve as attachment points for muscles.
- Irregular Bones: Include vertebrae, pelvis, and facial bones; these have complex shapes that do not fit into other categories, serving various functions including support and movement.
- Sesamoid Bones: The patella is the main example; these bones are embedded within tendons and protect them from stress and wear.
Vertebrae Classifications
- Cervical Vertebrae: Have an oval shape and concave surfaces; consist of seven vertebrae in the neck region, accommodating a range of head movement.
- Thoracic Vertebrae: Feature a heart shape and convex surfaces; consist of twelve vertebrae in the upper back, providing attachment for ribs and stability to the chest.
- Lumbar Vertebrae: Resemble a kidney shape with concave surfaces; consist of five vertebrae in the lower back, designed to bear the weight of the upper body and allow flexibility.
