Bone Classification and Types
This section details the classification of bones within the skeletal system, organizing them into major groups and specific types based on their characteristics and functions.
Definition: The skeletal system is divided into two major groups: the axial skeleton (skull, vertebral column, and rib cage) and the appendicular skeleton (bones of upper and lower limbs).
The five types of bones are:
Example: Long bones - Found in limbs except for the patella and wrist/ankle bones; includes the clavicle Example: Short bones - Cube-shaped bones found in wrists and ankles Example: Flat bones - Thin, slightly curved bones including the scapula, sternum, ribs, and most skull bones Example: Irregular bones - Uniquely shaped bones including vertebrae, hip bones, and jaw bones Example: Sesamoid bones - Specialized bones embedded in tendons, such as the patella
Highlight: The axial skeleton primarily focuses on protection and support, while the appendicular skeleton is crucial for locomotion.
