Study Notes

Muscle Attachment

Flattened muscles are attached to bones by a thin but strong sheet of fibrous tissue called an aponeurosis.
A raphe is an interdigitation of the tendinous ends of fibers of flat muscles.

Cartilaginous Joints

Cartilaginous joints can be divided into two types: primary and secondary.
Primary cartilaginous joints: bones are united by a plate or a bar of hyaline cartilage, allowing for a small amount of movement.
Example: union between the 1st rib and the manubrium sterni.

Synovial Joints

Articular surfaces of bones are covered by a thin layer of hyaline cartilage.
Joint cavity separates the articular surfaces.
Outer part of the shaft is composed of compact bone covered by a connective tissue sheath, the periosteum.

Flat Bones

Found in the vault of the skull (e.g., frontal and parietal bones).
Composed of thin inner and outer layers of compact bone.
Scapulae, although irregular, are included in this group of flat bones.
