Types Of Joints

Classification of Joints:

Synarthroses: immovable joints, joined by fibrous tissue, no cavity is present
           Example: Suture joints of the skull
Amphiarthroses: Slightly movable, joined by cartilage, no cavity is present
           Example:  Symphysis pubis
Diathroses: freely movable joints, most joints in the body, aka synovial joints


Types of Synovial Joints:

Ball and Socket: The joint moves 360 degrees (examples: hip and shoulder)
Gliding: one bone moves while the other one stays still (examples: tarsals, carpals, vertebra)
Pivot: rotational movement (examples: Atlas to Axis)
Saddle: allow angular movement of bone but greater movement than condylar (example: thumb)
Hinge:  moves like a door hinge (examples: knee, elbow, phalanges)
Condylar: allow angular movement between two axes (example: fingers)

Types of Bones

Image
a. Long bones: elongated shape, not necessarily in size -shaft with heads at both ends -primarily compact bone -contains spongy bone in its interior b. Short bones: cube-like -thin outer surface is compact bone -composed mostly of spongy bone -bones of wrist and ankle -sesamoid bones such as the patella: attach to tendons c. Flat bones: thin, flat, and usually curved -thin layers of compact bone around a layer of spongy bone -sternum, ribs, and skull bones d. Irregular bones: bones that don't fit into categories -examples: vertebra and hip bones -mostly spongy bone with thin outer layers of compact bone

Major Subdivisions

There are two main divisions in the skeleton, axial and appendicular. Axial: The  axial skeleton  consists of bones that form the skull, laryngeal skeleton, vertebral column, and thoracic cage. -The Skull -Paranasal Sinuses -Hyoid Bone -Fetal Skull -Vertebral Column -Bony Thorax: sternum, ribs, thoracic vertebrae Appendicular: The appendicular skeleton consists of the bones that form the upper and lower limbs, shoulder, and pelvic girdle. -Upper limbs: Humerus, Ulna, Radius -Hand: Carpals, Metacarpals, Phalanges -Lower Limb: Femur, Tibia, Fibula -Foot: Tarsals, Metatarsals, phalanges Pectoral Girdle: Clavicle, Scapula
